| 00:04:56 | ProtWork | Are there any schems of the comm board? |
| 00:05:50 | ProtWork | And the UCB1200 is a combined audio/telcom codec. It has a built in DAA so you can run the phone lines right into it. |
| 00:06:09 | SpaceCoaster | GPSFan: was doing schematics of stuff, I've just got the cave drawing and the ones with it |
| 00:06:28 | SpaceCoaster | ProtWork: that's what I thought, we don't need no stinking DSP! |
| 00:07:21 | SpaceCoaster | We are not likely to ever get the modem to work. |
| 00:07:26 | GoRK | so in theory if we just ran the phone line into the ucb1200 we could hear audio from that? |
| 00:07:44 | ProtWork | The audio codec has 12-bit resolution, the telcom codec is 14-bit, and 10-bit touchscreen control. |
| 00:07:53 | ProtWork | If the UCB1200 is ran into the StrongARM. |
| 00:08:07 | SpaceCoaster | yes, it is |
| 00:08:12 | GoRK | i thought the ucb1200 talked to the SA through the SIB too though? |
| 00:09:00 | SpaceCoaster | SIB != SPI, SIB = 8 bytes, dma, fifos, luxury, SPI = 1 bit twiddle city |
| 00:11:15 | SpaceCoaster | The DSP has lots of control lines, happy tones (for Aelhaz :-), timers etc, which are fine and should work but the audio? |
| 00:11:53 | GoRK | i am trying to read the stuff on the dsp itself |
| 00:12:02 | GoRK | i mean the words on the chip |
| 00:12:57 | SpaceCoaster | GoRK: the photos, or the chip, I used a pair of binoculars the wrong way around, worked fine, I think I've invented the microscope! |
| 00:13:44 | Aelhaz | Most flatbed scanners have a deapth of field of at least a few mm, pull the board off and scan it at the highest optical rez you've got |
| 00:14:14 | Aelhaz | I've used flatbed scanners that had a 4" deapth of field, you could literally prop them up over a non-flat object and get a pretty good image |
| 00:14:19 | GoRK | i was trying to read it without desoldering the mongoose daughterboard |
| 00:14:22 | Aelhaz | ah |
| 00:14:28 | rw-rw-rw- | does anyone have a tuxscreen outside of the US? |
| 00:14:50 | GPSFan | GoRK: Hi all, Yes I'm working on schematics, the UCB1200 is on the list , but at the bottom of the pile right now I'm almost done with the DRAM/SODIMM, it probably will be on the net tomorrow. |
| 00:15:17 | SpaceCoaster | GoRK: ah, indeed, RedBaron came the closest to unsoldering the cover. |
| 00:15:36 | GoRK | i already took the cover off.. i meant the whole board |
| 00:15:43 | GoRK | hmm i could take the whole board off |
| 00:16:00 | GoRK | if anyone thinks it would help.. |
| 00:16:31 | SpaceCoaster | GPSFan: where are these schematics online? |
| 00:16:31 | Aelhaz | well, the DSP board is the only board we have schematics for, really |
| 00:16:34 | GoRK | GPSFan: where are you putting these? |
| 00:16:34 | Aelhaz | from lucent i mean |
| 00:17:17 | GPSFan | GoRK: the start of the main board PCMCIA is at : http://ipaq.secret.org.uk/TuxScreen/tux.pdf |
| 00:17:55 | GPSFan | Courtsy of Tangent. |
| 00:18:24 | GPSFan | (sp?) |
| 00:21:51 | SpaceCoaster | GPSFan: could you look for a realtime clock chip? It's just something I'm becoming obsessed with! |
| 00:22:53 | GPSFan | SpaceCoaster: There ain't none on the main board, I don't think there is one on the I/O board and I haven't taken my DSP off yet. |
| 00:24:24 | Tangent | SpaceCoaster : Isn't RTC part of SA1100? |
| 00:24:41 | SpaceCoaster | GPSFan: funny omission really, when they put so much else in. |
| 00:25:31 | ProtWork | Eh, the RTC needs a battery usually. |
| 00:26:07 | Tangent | ProtWork : There's 4 of em :) |
| 00:26:22 | ProtWork | Tangent: On the strong arm? Or are you just looking at timers/counters? |
| 00:26:46 | Tangent | ProtWork : I'm working on the assumption that RTC is the same as the iPAQ (which is provided by SA1100) |
| 00:26:47 | SpaceCoaster | sometimes they are in the chip, my sun4 has such a beast, new chip every 8 years or so, on it's second one |
| 00:27:20 | GPSFan | SpaceCoaster: if you have an internet connection, you have REAL time. usually a PC running Linux or Windoze uses a timer to keep track of time untill the power goes off. |
| 00:28:52 | ProtWork | Tangent: Does the iPAQ have the companion chip? |
| 00:29:16 | SpaceCoaster | GPSFan: true, I am writing a suite of programs, including a clock app, if you power off the TuxScreen it is wrong, unless it can get to the server, not a REAL problem, just interested |
| 00:29:17 | Tangent | ProtWork : Nope.. no SA1111 in the iPAQ |
| 00:29:33 | Tangent | ProtWork : The RTC on the SA1100 is detailed in section 9.3 od the SA1110 manual |
| 00:30:12 | ProtWork | Tangent: Hrm. Well, they asked about it. I figured it would get the TOD from CID, then update the RTC on the ARM accordingly. |
| 00:31:42 | SpaceCoaster | ProtWork: Hmm, so those tele-sales calls could prove useful at last, no one else calls much :-), tho buying caller id just for that seems a bit perverse. |
| 00:33:21 | Tangent | SpaceCoaster : May as well just ignore the phone :) |
| 00:33:27 | ProtWork | SpaceCoaster: *shrug* You told me that the box got the TOD from the DSP. |
| 00:34:00 | ProtWork | I'm still in pure theory mode, considering my TuxScreen doesn't get shipped until Friday. |
| 00:35:45 | SpaceCoaster | Tangent: the ringers turned off and the sound turned down, might take out the tape soon. |
| 00:36:18 | ProtWork | Tape? |
| 00:36:37 | Tangent | SpaceCoaster : Just change the message to match mine... 'Hi. I haven't answered your call... Leave me a message if it makes you feel better.. It'll be automatically deleted after 7 days... beep" |
| 00:37:43 | SpaceCoaster | ProtWork: yes, it does when the DSP is reset but the DSP must be getting it from somewhere, don't worry it will be clearer later. |
| 00:39:03 | ProtWork | SpaceCoaster: K. |
| 00:39:54 | Sammy | moening all |
| 00:41:17 | Tangent | Sammy : You're up early today |
| 00:41:21 | Tangent | Sammy : Morning BTW |
| 00:43:08 | SpaceCoaster | back to the driver, thanks everyone |
| 00:44:51 | GoRK | WHEATIES |
| 00:44:55 | GoRK | goes to eat |
| 00:45:35 | Sammy | Tangent : not to early almost 10 o'clock |
| 00:49:10 | Tangent | Sammy : I'm just used to you saying morning around the same time I say G'night... i.e. about 5AM here |
| 00:56:11 | Sammy | Tangent : not sleep all nigh ? should take some sleep :-) |
| 00:56:24 | Sammy | er night |
| 00:56:31 | Tangent | Sammy : Nah.. electricity is cheaper at this time of day (erm.. night) |
| 00:56:46 | Tangent | Sammy : Not that it's a concern... just an excuse :) |
| 00:58:02 | Tangent | Sammy : Since I don't have a job at the moment, I only need 4-6 hours downtime a night |
| 00:59:37 | Tangent | as_ : Morning Nightowl |
| 01:01:28 | as_ | HAha, Evnin Tangent. |
| 01:01:44 | Sammy | Tangent : even I have job at this moment , I still only can have almost 6 hours to zzz |
| 01:28:22 | RedBaron | Sweet. Got the voltage regulators all wired up and working. |
| 01:32:41 | Aelhaz | http://store.yahoo.com/justdeals/luctecorsil1.html !? |
| 01:34:42 | other | wow |
| 01:35:04 | other | that 3.3v? |
| 01:35:15 | Aelhaz | dunno |
| 01:35:20 | Aelhaz | great price for those tho |
| 01:35:33 | Aelhaz | if i didn't have a spare wireless nic already i'd jump on 'em |
| 01:35:43 | other | i have no wireless as of yet. |
| 01:36:38 | Aelhaz | I have a little linksys wap11 access point, a linksys wireless nic, and a LeArtery wireless nic i got on ebay for $40 |
| 01:37:30 | other | if i had a laptop, i'd buy one or more of those. |
| 01:37:38 | Aelhaz | laptops are grand |
| 01:37:54 | as_ | Yikes 11MBit?!? |
| 01:38:03 | other | not 802.11a yet. |
| 01:38:12 | as_ | I wonder what band it works on. Dont think we have anything like that here. |
| 01:38:28 | Aelhaz | as_: 2.4ghz |
| 01:38:40 | Aelhaz | 2.40 to 2.48 in the us |
| 01:38:41 | other | its pretty standard. |
| 01:38:44 | Aelhaz | yeah |
| 01:39:10 | other | store.yahoo.com is having some problems.. |
| 01:39:58 | as_ | Last I looked the only wireless systems here were kbit data rates :/ |
| 01:40:00 | other | Aelhaz: how do you like the linksys stuff? |
| 01:40:07 | RedBaron | $60 on an orinoco silver? Nice. |
| 01:40:26 | Aelhaz | other: the AP is pretty alright |
| 01:40:33 | Aelhaz | other: the nic is OK I guess |
| 01:40:42 | Aelhaz | i got a great deal on both of 'em |
| 01:41:01 | Aelhaz | staples had $50 rebates on both of 'em, and i had coupons for $40 off and $30 off |
| 01:41:06 | other | moce/ |
| 01:41:08 | other | er nice. |
| 01:41:09 | Aelhaz | it was quite a scam |
| 01:41:17 | other | staples is usually a bitch about those things |
| 01:41:22 | other | you must have gotten lucky |
| 01:41:23 | other | :) |
| 01:42:25 | RedBaron | Hey SpaceCoaster. Got my voltage regulators all wired up and working. |
| 01:42:41 | SpaceCoaster | woohoo |
| 01:42:58 | SpaceCoaster | what batteries are you planning on using? |
| 01:43:03 | Aelhaz | other: Linksys seems to be updating the AP firmware pretty actively. Nice stuff like MAC and IP filtering. |
| 01:43:16 | Aelhaz | other: to make it 10% more difficult for passing geeks to abuse my network |
| 01:43:17 | RedBaron | Now...I gotta wire up a plug sacrificing the bogus power supply that originaly came with my tuxscreen |
| 01:43:46 | RedBaron | SpaceCoaster: NiCD most likely. Right now I have a lead acid gel battery I borrowed from work to test it with |
| 01:43:57 | other | haha |
| 01:43:57 | other | nice. |
| 01:44:03 | Aelhaz | NiCD are the pits, why not NiMH? |
| 01:44:25 | RedBaron | Aelhaz: erm..I think I meant nimh. I forget. :) |
| 01:44:29 | other | i want to bring my tuxscreen to class. |
| 01:45:33 | RedBaron | Aelhaz: I can never keep the two names straight. |
| 01:49:50 | SpaceCoaster | how long do you hope it will run from batteries? |
| 01:51:26 | Aelhaz | A lot of the wearables folks build designs based around Sony InfoLithium packs |
| 01:51:39 | Aelhaz | or camcorder batteries |
| 01:51:42 | RedBaron | Hmm...why lithium? |
| 01:52:29 | RedBaron | SpaceCoaster: I dont realy know. I havent measured the current draw of this thing. I'm hoping at last 1.5 hours though..thats figuring off what the power supply is rated at. And the tux better not draw that much. |
| 01:53:10 | Tangent | Anyone here familiar with Dallas DS1820 ? (Just on the offchance) |
| 01:53:59 | SpaceCoaster | one wire thermometer? |
| 01:54:21 | Tangent | SpaceCoaster : Yeah.. that's the one |
| 01:54:44 | Aelhaz | RedBaron: lithium get twice the volts per cell, are generally longer lasting |
| 01:54:45 | Tangent | SpaceCoaster : I'm part way through implementing the search rom command, and now my head hurts |
| 01:55:16 | Tangent | SpaceCoaster : I'm part way through implementing the search rom command, and now my head hurts |
| 01:55:28 | SpaceCoaster | I have some wire up via a Dallas TINI board, neat |
| 01:55:42 | Tangent | SpaceCoaster : Neat indeed :) |
| 01:55:58 | Tangent | SpaceCoaster : I've spent days several days messing with them :) |
| 01:56:01 | SpaceCoaster | I used dallas libraries, so mostly higher level stuff |
| 01:56:28 | SpaceCoaster | they supply source code, i think |
| 01:56:34 | Tangent | SpaceCoaster : Nod.. that's the stuff I'm trying to code on my PIC board at the moment... |
| 01:56:48 | Tangent | SpaceCoaster : It all becomes much more fun with only one working register... |
| 01:56:49 | RedBaron | Aelhaz: But whats the amphour rating on lithium compared to nimh? |
| 01:57:20 | RedBaron | okay...the power connector for the tuc is wired weirdly. |
| 01:57:30 | RedBaron | s/tuc/tux |
| 01:58:09 | SpaceCoaster | derek goes to watch friends |
| 01:58:25 | SpaceCoaster | s/derek// |
| 01:59:02 | Aelhaz | RedBaron: I don't have numbers handy . . the pack on the back of my notebook, a few years old, is 10.8v 2600mAh, probably has six A cells in it |
| 01:59:28 | Tangent | AlHaz : 2600mAh sounds more like C cells |
| 02:00:15 | Aelhaz | http://www.mjsales.net/sonycam1.htm |
| 02:00:27 | Aelhaz | Tangent: the pack is a little thicker than AA cells |
| 02:00:33 | Aelhaz | which is why i say A cells |
| 02:00:37 | Tangent | Lithium-ion batteries are typically 20-35% lighter and will provide 10-20% better performance than a NiMH battery of equivalent mAh rating. |
| 02:00:38 | Aelhaz | long & skinny |
| 02:01:03 | Tangent | http://www.cellpower.com/battery_tips.cfm |
| 02:01:14 | RedBaron | hmm |
| 02:02:24 | RedBaron | Tangent: nice page. thanks |
| 02:02:54 | RedBaron | I'm realy just a software geek who knows just barely enough electronics to get myself in trouble. :) |
| 02:04:34 | Tangent | RedBaron : Heh.. I'm a hardware geek who knows just enough software to be dangerous :) |
| 02:04:56 | Tangent | Actually.. I know just enough hardware to be dangerous too |
| 02:05:02 | Tangent | is a bloody liability :) |
| 02:05:16 | Aelhaz | the wearables bunch probably know more about retrofitting stuff for battery power than any other group publishing schematics on the net . . |
| 02:06:05 | RedBaron | Tangent: *grin* |
| 02:06:28 | RedBaron | Aelhaz: *nod* |
| 02:07:00 | GPSFan | Tangent: howdy! I have some more schematic data, the DRAM & SODIMM aread are pretty much done, Flash is almost done too. |
| 02:07:41 | Tangent | GPSFan : Cool... mail it over and I'll update the PDS |
| 02:07:42 | Tangent | PDF |
| 02:08:17 | GPSFan | Tangent: on its way, 4 files. |
| 02:14:55 | RedBaron | Just looked up the price on some lithium AA's. And they are listed here at 2600mAhr. |
| 02:16:55 | RedBaron | But lithium is 1.5V where nimh is 1.2V..not that much more..but I could save about 3 batteries that way. |
| 02:17:57 | Aelhaz | um, no, lithium is 3v |
| 02:18:35 | RedBaron | OKay...maybe mcmaster-Carr is wrong..but they say 1.5 for a lithium AA. *shrug* |
| 02:19:29 | Aelhaz | hmm |
| 02:19:39 | Aelhaz | oh, no, that's non-rechargable lithium |
| 02:19:43 | Aelhaz | I mean lithium-ion |
| 02:19:50 | RedBaron | Ah. ok |
| 02:19:53 | RedBaron | That would be it |
| 02:20:56 | Aelhaz | LiIon aren't packaged as alkaline-replacers for that and other reasons |
| 02:22:23 | RedBaron | Do you know of any place that sells LiIon batteries that arent cell phone batteries? |
| 02:23:31 | Aelhaz | RedBaron: Dunno. I figured batteriesplus would but i don't see 'em on their page |
| 02:23:47 | Aelhaz | you mean individual cells for which you will build your own charger circuit, right? |
| 02:25:03 | RedBaron | Aelhaz: Well...I believe thats the best way to go. Because I can then fit the cells into my webpad-ified tuxscreen where there will be holes that would be nice to fill up with batteries. But..I know nothing about building chager circuits. |
| 02:27:30 | Aelhaz | RedBaron: I'm pretty sure there are a lot of single chip lithium charger controllers, prolly would come with spec sheets, etc. |
| 02:28:13 | RedBaron | Aelhaz: Acutaly...just happened to see one on digikey. made by TI. |
| 02:28:19 | RedBaron | Aelhaz: was looking for batteries |
| 02:28:44 | Aelhaz | RedBaron: camcorder battery packs seem to be popular for wearable projects |
| 02:28:56 | Aelhaz | I'm not sure why, other than being nice, easy to aquire, self-contained boxes |
| 02:31:08 | RedBaron | Aelhaz: *nod* I'm going for a webpad type setup with the tuxscreen. Just the touchscreen, the pcmcia slots, the IR port, the serial, the reset button and a charger port being used/availible. And because of how the two boards in the tux are layed out, there will be large gaps inside this thing that a AA just fits inside nicely. |
| 02:31:25 | | cosmicpenguin was last seen on #tuxscreen 1 days, 2 hours, 17 minutes and 17 seconds ago, saying: bye! [Wed Oct 17 01:14:08 2001] |
| 02:31:25 | Russ | ibot: seen cosmicpenguin |
| 02:31:50 | SpaceCoaster | Russ: he is in vegas till monday. |
| 02:32:28 | Russ | ah |
| 02:32:38 | Russ | redoing the touchscreen ioctls |
| 02:32:45 | SpaceCoaster | Russ: I have to make the dsp work before he gets back :-) |
| 02:33:03 | RedBaron | Russ: Did cosmicpenguin pass on to you my hack to make the screen+ and screen- keys work? |
| 02:33:12 | Russ | RedBaron: no, is it a kernel thing? |
| 02:33:22 | Russ | should really be a microwindows thing |
| 02:33:25 | Aelhaz | RedBaron: the NP-550 is 1&5/8" x 3/4" x 2&3/4" |
| 02:34:11 | RedBaron | Russ: kernel, microwindows, and tuxscrwm. Had to add the scancode to keycode mapping in the kernel because I didnt think we had the keyboard utils in the dist. Do we? |
| 02:35:00 | Aelhaz | They do cost $45 each, tho |
| 02:35:06 | Aelhaz | *shrug* |
| 02:35:06 | RedBaron | Aelhaz: *nod* |
| 02:35:18 | Aelhaz | 7.2v 1500mAh |
| 02:36:46 | Russ | right now, the keyboard has two layes |
| 02:36:50 | Russ | er, layers |
| 02:37:00 | Russ | the layer that passes it to the input portion of the kernel |
| 02:37:19 | Russ | and the layer that reads hooks into the input portion of the kernel and spits out keys |
| 02:37:35 | Russ | the second portion isn't neccessary if you read directly from the input layer |
| 02:39:32 | RedBaron | Russ: *nod* Okay |
| 02:39:41 | RedBaron | Russ: What I did was I edited input_keyb.c to map the scancode of those two keys to the a keycode that wasnt being used. Because microwindows just deals in keycodes. Its a three line change. |
| 02:41:47 | RedBaron | Russ: Was there a better way to do it? I'm not exactly sure how the scancodes and keycodes work into what you just said. The screen+ and screen- scancodes werent known by the kernel. |
| 02:46:23 | Russ | you could possibly change it in shannon_ikbd.c to a more commonly used char that isn't on the keyboard |
| 02:47:31 | RedBaron | Ah. Yes. That would make more sense. did not notice the shannon_ikbd.c. |
| 02:48:34 | Tangent | OK.. latest diagrams are all up at http://ipaq.secret.org.uk/TuxScreen |
| 02:49:07 | RedBaron | Well.....Its the time of truth. Time to see if I wired up this circuit correctly and if the tux will work or smoke. |
| 02:49:07 | Tangent | This IRC client sucks |
| 02:50:00 | Tangent | RedBaron : What are you about to try? |
| 02:51:05 | Tangent | reads the scrollback instead |
| 02:51:18 | RedBaron | Tangent: Powering my tux off a battery. a while ago I got my voltage regulators to work correctly. I just wired it into the same style connector that the tux power cable uses |
| 02:51:30 | RedBaron | Tangent: checked....rechecked....checked again...and it all looks good. |
| 02:52:02 | Tangent | RedBaron : Oooh.. interesting.. How are you doing the 3.3V supply? Bang Bang converter? |
| 02:52:31 | RedBaron | Tangent: Two switching DC-DC convertors. I'm powering those off a 12V battery I borrowed from work |
| 02:54:12 | Tangent | RedBaron : Nod.. among other things I've been playing with lately, switchmode converters are high on the list right now |
| 02:55:34 | RedBaron | Tangent: *nod* They are supposed to be much better on the power consumption than the ones that basicly a resistor that burns off that energy |
| 02:56:30 | Tangent | RedBaron : Given ideal components, 100% efficient... |
| 02:58:19 | RedBaron | Alright...looks good on the actual connector pins. I guess its time to see what happens |
| 02:58:38 | GPSFan | Tangent: Thanks, more to come tomorrow. Look at the SODIMM, A12 is connected to nCS1. that may explain some of the memory oddness. |
| 03:00:01 | RedBaron | Woohoo! She works! |
| 03:00:14 | Tangent | GPSFan : You must have the patience of a saint |
| 03:00:18 | Tangent | RedBaron : Woohoo :D |
| 03:01:50 | GPSFan | Tangent: the Flash is driving me nuts, there are on board jumpers to support different types of flash, and lots of 0 Ohm resistors ;>)) |
| 03:02:24 | RedBaron | Wow. The tux only draws .3 amps. |
| 03:02:55 | GPSFan | RedBaron: wait till you put in a PCMCIA card. |
| 03:03:01 | Tangent | RedBaron : Cool.. so my plans to run it from my solar panels are justified then :) |
| 03:03:17 | RedBaron | GPSFan: Heh. Good point. |
| 03:03:45 | RedBaron | Tangent: Yah..that was just the tux with the screen. No cards. I'm rather surprised it was only .3A |
| 03:04:24 | Tangent | RedBaron : Yeah.. that seems very low... erm.. 4W... Is the backlight on? |
| 03:04:41 | GPSFan | Tangent: BTW wnen this schematic business is done we may have a design that could be reproduced with our on mods, a-la-LART. |
| 03:04:54 | GPSFan | s/on/own |
| 03:04:59 | RedBaron | Tangent: yes it is |
| 03:05:06 | Tangent | GPSFan : Heh. and OrCAD can even route the CB for us too :) |
| 03:05:11 | Tangent | s/CB/PCB/ |
| 03:05:57 | GPSFan | Tangent: I can generate a netlist that I could route with Orcad PCB, it looks like a 4 or 6 layer board. |
| 03:06:03 | SpaceCoaster | RedBaron: congrats |
| 03:06:34 | RedBaron | SpaceCoaster: Thanks. :) |
| 03:06:51 | SpaceCoaster | DSP update I made the input lines from the DSP toggle! |
| 03:06:58 | RedBaron | In case anyone cares, it looks like the PFI line on the power supply doesnt matter. I have that unconnected and the machine works fine. |
| 03:07:40 | SpaceCoaster | I can't believe the 1 bit interface, it's blowing my mind |
| 03:07:44 | Tangent | GPSFan : Pah... I can only make single sided right now.... |
| 03:07:54 | Tangent | SpaceCoaster : Damn cool isn't it :) |
| 03:08:38 | SpaceCoaster | 500 usecond delays all over the place, bring back cans and string. |
| 03:08:55 | GPSFan | Tangent: Oh well, I might do something if Intel haden't discontinued the SA1100 in favor of the SA1110. :>( |
| 03:12:14 | RedBaron | Whelp. goodnight everyone. time for me to sleep |
| 03:12:31 | SpaceCoaster | see ya |
| 03:12:34 | Tangent | RedBaron : Night |
| 03:12:50 | Tangent | SpaceCoaster : You gotta admire the parasitic power thing on the 1-wire bus tho' |
| 03:13:01 | Tangent | SpaceCoaster : Really neat way of doing things |
| 03:14:29 | SpaceCoaster | Tangent: yes that is cool |
| 03:16:38 | GPSFan | nite all.... |
| 03:16:48 | Tangent | GPSFan : Night |
| 03:16:58 | Tangent | Hrm.. actually, that's not a bad idea... |
| 03:17:04 | Tangent | goes to defrag brain... |
| 03:17:06 | Tangent | Night all |
| 03:17:09 | Tangent | <- Zzzzzzz |
| 03:17:32 | Aelhaz | input lines from the dsp toggle? what does that mean? |
| 03:19:57 | SpaceCoaster | Aelhaz: the data input line is changing between 1 and 0 when I shuffle the data from/to the DSP. |
| 03:21:35 | Aelhaz | SpaceCoaster: ok, um, what are those input lines connected to? |
| 03:22:12 | Aelhaz | <-- ignorant. or as they say in southern utah, ignert |
| 03:22:47 | SpaceCoaster | Aelhaz: well it's just one line, it's an input to the SA1100 and an output from the DSP, it's GPIO11 on the SA1100 |
| 03:23:10 | Aelhaz | ok |
| 03:24:03 | SpaceCoaster | I am sortof at the same place as I was with the touchscreen, waiting for a read confirm bit to toggle. |
| 03:25:04 | Aelhaz | *nod* |
| 03:25:28 | SpaceCoaster | Aelhaz: it should start singing those happy tones tomorrow, goodnight |
| 03:25:35 | Russ | attepts to build 2.4.10-ac11-rmk1-np1-tux1 |
| 03:25:42 | Aelhaz | heh |
| 03:25:45 | Aelhaz | g'nite |
| 03:37:03 | BZFlag | RedBaron got battery power working, cool. "socket" low power ethernet shoud only add 65mA max. |
| 03:47:29 | GoRK_ | if youre running on a battery, what's the fun of wired ethernet? |
| 03:49:07 | BZFlag | oh! that is the pcmcia version. the CF version is only 19mA |
| 03:49:29 | Proteus | Once again, I /join into the middle of a convo. :-) |
| 03:50:08 | BZFlag | Proteus: heh, I was just replying to an old one. RedBaron got a tux running on battery power. |
| 03:50:33 | Proteus | BZFlag: Wow. How much more cktry does Shannon have compared to a LART? |
| 03:51:02 | GoRK | it has more pieces |
| 03:51:05 | GoRK | hehehe |
| 03:51:08 | Proteus | *lol* |
| 03:51:23 | Proteus | I was wondering what kind of current draw Shannon had. |
| 03:51:31 | GoRK | 1.21 jiggawatts |
| 03:51:44 | BZFlag | RedBaron claims .3A |
| 03:51:46 | GoRK | or .3A |
| 03:51:58 | andersee | GoRK: but only when moving at 88 mph... |
| 03:52:14 | scanline | Hehe. So will it have a lightning rod? |
| 03:52:25 | GoRK | i think the flux capacitor in my phone was improperly wired up |
| 03:52:31 | scanline | haha |
| 03:52:42 | GoRK | or i did not pour enough beer into the mr. fusion unit |
| 03:52:44 | BZFlag | mine runs the lightning screen saver from time to time. |
| 03:52:52 | Proteus | RedBaron is some Shannon w/ethernet? |
| 03:52:57 | scanline | not beer, empty beer cans |
| 03:53:04 | BZFlag | RedBaron is a user with a tux |
| 03:53:15 | GoRK | and beer too. beer is good for mr. fusion |
| 03:53:29 | GoRK | and it became too much for him to bear... |
| 03:54:07 | Proteus | Grr. Damn packet fragmentation. |
| 03:59:25 | Proteus | Mmm. Can't wait to get my screen. |
| 04:01:13 | GoRK | hmm ok so can a phone line be hooked directly into the UCB1200? |
| 04:01:19 | GoRK | for audio purposes |
| 04:01:26 | Russ | I'm thinking possibly |
| 04:02:30 | Proteus | Yes, a phone line can be hooked directly into the UCB1200. |
| 04:02:39 | Proteus | pulled the spec for the chip earlier. |
| 04:02:48 | GoRK | Proteus: does it have a schematic on there |
| 04:03:34 | Proteus | GoRK: Just a moment... |
| 04:03:36 | Proteus | GoRK: Just a moment... |
| 04:05:36 | Proteus | Nope, but they have plenty of information on the datasheet for you to understand how it works. |
| 04:06:05 | Proteus | http://www.semiconductors.philips.com/pip/ucb1200be |
| 04:10:24 | Proteus | Anyways, that'll get you guys all the info you'd ever want about the UCB1200. |
| 04:12:25 | Russ | new driver coming out soon hopefully |
| 04:14:55 | Russ | attempting to boot kernel now |
| 04:15:59 | andersee | Russ: cool |
| 04:16:11 | Russ | ucb1x00_audio_init chokes |
| 04:16:32 | GoRK | on 2.4.10 or currently? |
| 04:16:34 | andersee | I'm compiling 2.4.12-ac3-rmk2 on my netwinder at the moment... |
| 04:16:44 | Russ | 2.4.10-ac11-rmk1-np1-tux1 |
| 04:17:23 | Russ | Linux version 2.4.10-ac11-rmk1-np1-tux1 (russ@russ) (gcc version 2.95.2 19991024 (release)) #7 Wed Oct 17 22:14:48 MST 2001 |
| 04:17:55 | GoRK | does the ucb1200 audio device work with the current 2.4.7 kernel that we are using in buildroot? |
| 04:18:18 | Russ | dunno, a whole bunch of stuff relating to the ucb1x00 will have to change though |
| 04:18:52 | GoRK | what happened to it? |
| 04:18:56 | Russ | new driver |
| 04:19:30 | GoRK | ahh |
| 04:19:52 | GoRK | well in theory, the audio driver in the 2.4.7 should work if we hook something up to the audio, right? |
| 04:20:03 | Russ | yah, it plays...to nowhere |
| 04:20:06 | andersee | 2.4.9-ac10-rmk3 added "New MCP/UCB1x00 drivers" by Russell King |
| 04:20:26 | Russ | ucb1x00_io_set_dir... |
| 04:20:39 | GoRK | hmm i may find those pins and stick a multimeter on them and play a tone.. read rms frequency and see if i get something |
| 04:20:56 | Russ | hmm....why is the ts being inited before the ucb |
| 04:45:47 | Lenolium | UCB1200 can play audio? |
| 04:49:54 | Proteus | Yes, it can. |
| 04:51:13 | Lenolium | Woah. Is it hooked up to anything? |
| 04:51:25 | GoRK | nope |
| 04:51:46 | Lenolium | Oh. bummer. |
| 04:52:57 | Proteus | Why didn't they hook that up? Were they just using the DAA? |
| 04:53:48 | GoRK | they didnt require audio applications at all |
| 04:54:09 | GoRK | it was just a phone |
| 04:54:10 | andersee | presumably one could easily hook a power transistor up to the ucb1200 audio output and connect that to the phones speaker.... |
| 04:54:38 | Proteus | I'm seriously amazed that they used the UCB1200 when all they needed was a DAA and an ADC. |
| 04:54:46 | GoRK | andersee: if you could hook it up to the DSP, it'd be better. the DSP has audio routing |
| 04:55:02 | andersee | ahh. that would be better |
| 04:55:13 | andersee | Then you could decide were to send the output... |
| 04:55:29 | GoRK | they used the UCB1200 probably because it was easier for them to work with... |
| 04:56:00 | GoRK | i wouldnt think it'd be all that significantly more expensive than designing new circuts with different hardware |
| 04:56:31 | GoRK | what is the v.34 software modem on this thing? |
| 04:58:52 | Proteus | The damn chip is eight bucks! I could build a 14-bit ADC and DAA for half that cost. |
| 04:59:01 | Proteus | And if there's one thing that rules Philips, it's cost. :-) |
| 04:59:43 | Proteus | But, it's time for me to bail for the evening. |
| 04:59:48 | Proteus | TTY all later. |
| 04:59:51 | GoRK | heh. they did run the shannon into the ground after dumping $30M into it :) |
| 05:00:07 | Proteus | GoRK: I meant with final product cost, not investment cost. :-) |
| 05:00:12 | Proteus | ttyt. |
| 05:05:01 | GoRK | hmm im going to explore hooking the ucb1200 up to the phone's audio circutry |
| 05:08:05 | GoRK | i can't read the PDF's from philips at all! |
| 05:10:24 | BZFlag | hmm... I thought I saw that the ucb1200 audio was connected to the DSP which could route it to the speaker/handset or phone line? |
| 05:11:05 | GoRK | i was going to look up which pins were the audio ones and see for sure.. was that from the cave_drawings schematic? |
| 05:12:01 | GoRK | that would, of course, make sense |
| 05:13:14 | GoRK | how many layers is this comm board? it looks to be only 3 |
| 05:13:34 | GoRK | with GND only in the middle |
| 05:14:32 | GoRK | mumbles and goes to get a meter |
| 05:39:49 | GoRK | why would they print "Message" above the big LED if it couldn't record audio? |
| 05:40:04 | GoRK | maybe the UCB1200 is the DSP's "Line2" |
| 05:40:39 | andersee | Hmm. That would be a sensible thing for them to have done.... |
| 05:42:05 | Lenolium | GoRK: It can detect if you have a new message at the CO |
| 05:42:24 | GoRK | oh. hrm. how does it do that? something with CID? |
| 05:43:09 | GoRK | i cant seem to trace it. there's nothing on the schematic for the mongoose board that shows that it is connected up there... not that i can tell anyway |
| 05:47:41 | GoRK | ok where is the modem in this exactly? is it provided by the DSP or by the ucb1200? |
| 05:49:54 | Lenolium | GoRK: Supposidly, DSP. |
| 05:50:27 | GoRK | hmm page 34 of the UCB1200 manual looks interesting... |
| 05:54:33 | GoRK | interesting.. philips has a v.34 software modem for the PR31500 and PR31700 MIPS processor that use only the ucb1200 |
| 05:54:44 | GoRK | so the UCB1200 could be a modem also. heh |
| 06:41:00 | nicknam3 | hi. |
| 06:41:35 | nicknam3 | Is there anybody who can help me installing pgui on a SA1100 board? |
| 06:43:26 | GoRK | is this a tuxscren or something else? |
| 06:44:43 | GoRK | what is your SA1100 board? |
| 06:45:23 | nicknam3 | it is an Arnold board.. |
| 06:45:38 | nicknam3 | unknown board .-) |
| 06:46:04 | GoRK | ah. well, first, it's probably best to discuss this in #picogui instead of here |
| 06:46:42 | nicknam3 | oh.. well. I thought that there is no difference between SA and tuxscreen..but you're right :.) |
| 06:46:46 | nicknam3 | zorry |
| 07:48:58 | BZFlag | nite |
| 07:51:52 | GoRK | whoot libiax is all ready for some audio functionality :) |
| 11:06:41 | Tangent | wakes up |

| 14:09:47 | ctr | well |
| 14:09:51 | ctr | in brum i should say |
| 14:10:38 | SpaceCoaster | the accent, my wife worked in birmingham for 3 months, took two years to drop the accent and she's from california |
| 14:10:56 | SpaceCoaster | from the wiki |
| 14:10:56 | ctr | mwhahahahahahahahahahha |
| 14:11:02 | ctr | ahahaha |
| 14:11:08 | ctr | the brum accent is terible |

| 14:13:47 | SpaceCoaster | I'm from Basildon in Essex so I can't really speak, well not clearly |
| 14:14:02 | ctr | heh |
| 14:14:09 | ctr | so you are from the uk =P |
| 14:14:44 | SpaceCoaster | yup, got to the US just in time for all the jobs to vanish :-( |
| 14:14:59 | ctr | shit |
| 14:15:02 | ctr | you working at the moment? |
| 14:15:26 | SpaceCoaster | yes, on my TuxScreen! |
| 14:15:36 | ctr | heh |
| 14:15:42 | pattieja | is away: bank |
| 14:15:48 | ctr | well i am from bucks :) |
| 14:15:56 | ctr | so i speak the queens english :) |
| 14:18:14 | kram | has returned. |
| 14:18:28 | SpaceCoaster | well done!, tho' coming from Essex is good too, for mostly the wrong reasons. |
| 14:20:44 | mallum | ctr: I am from berks ( sort of ) |
| 14:21:30 | SpaceCoaster | mallum: I lived in Lower Earley for 10 years |
| 14:22:11 | SpaceCoaster | ctr: I worked in Milton Keynes for Mercury aka Cable and Wireless. |
| 14:22:32 | SpaceCoaster | mallum: where 'bouts? |
| 14:24:59 | pattieja | is back (gone 00:09:17) |
| 14:28:13 | prpplague | SpaceCoaster: not enough tech jobs in the uk? |
| 14:29:02 | SpaceCoaster | nah, always wanted to give the US a try. |
| 14:29:20 | prpplague | fun, i've always wanted to give the UK a try |
| 14:30:43 | SpaceCoaster | my wife did she went, to the uk, for a week and stayed 10 years |
| 14:31:12 | prpplague | lol |
| 14:31:41 | prpplague | anyone had experience with the smsc ethernet chipset? |
| 14:33:03 | ctr | lives in Aston Clinton, nr Aylesbury, Bucks |
| 14:33:10 | ctr | but i am at uni in bham |
| 14:33:29 | mallum | SpaceCoaster: well I was born in Middlesex, moved to maidenhead for most of my teens, now live in north London. |
| 14:34:12 | prpplague | man i knew there was a reason i like the people in this channel... |
| 14:34:41 | prpplague | live longview texas |
| 14:36:27 | SpaceCoaster | lives half moon lake, new hampshire |
| 14:36:50 | mallum | dont fuck with texas |
| 14:38:09 | SpaceCoaster | don't let the guys from Utah hear you talking like that, ohh my |
| 14:40:19 | mallum | utah is harder than texas ? |
| 14:40:29 | mallum | who would win in a fight ? |
| 14:40:40 | mallum | I though texas could whip any other state ? |
| 14:40:49 | mallum | s/though/thought/ |
| 14:41:01 | SpaceCoaster | mallum: glasgow |
| 14:41:30 | prpplague | utah in my mind would be about the only other state with the pionering spirit like texas |
| 14:41:44 | SpaceCoaster | i'll drink to that |
| 14:43:38 | mallum | yeah glasgow could probably kick texas's arse no problems |
| 14:43:59 | mallum | for that matter it could probably kick most small continent's arses |
| 14:44:17 | mallum | If given enough special brew |
| 14:46:54 | SpaceCoaster | lol, true, miss the special brew, lived in Scotland for 5 years, and miss the fish suppers most of all. |
| 14:56:00 | prpplague | hmm, someone said brew.... |
| 15:00:10 | prpplague | i'd just about kill for a real stout, porter, or ale, instead of the yellow stuff they drink here in texas |
| 15:00:52 | mallum | special brew is pretty yellow |
| 15:01:06 | SpaceCoaster | special brew is about 8% alcohol, it's yellow too, it's really the quantity thats important |
| 15:01:18 | Russ | what about strange brew? |
| 15:01:26 | prpplague | pilsner or larger? |
| 15:02:11 | Russ | moranis |
| 15:02:41 | SpaceCoaster | Russ: can I ask you a quick kernel question? |
| 15:03:01 | Russ | I'm leaving in a sec |
| 15:03:18 | mallum | SpaceCoaster: HSL is even worse - I havn't drunk that though since I was a teenager |
| 15:03:23 | SpaceCoaster | how do i install a handler for a GPIO interrupt? |
| 15:03:50 | SpaceCoaster | gpio14 is supposed to interrupt but I don't know how to trap it. |
| 15:04:54 | Russ | et_GPIO_IRQ_edge( GPIO_H3600_NPOWER_BUTTON, GPIO_RISING_EDGE ); |
| 15:04:57 | Russ | er |
| 15:05:03 | Russ | set_GPIO_IRQ_edge( GPIO_H3600_NPOWER_BUTTON, GPIO_RISING_EDGE ); |
| 15:05:25 | SpaceCoaster | but where does the handler routine ? |
| 15:05:47 | Russ | result = request_irq(IRQ_GPIO_H3600_ACTION_BUTTON, action_button_handler, SA_SHIRQ | SA_INTERRUPT | SA_SAMPLE_RANDOM, NULL) |
| 15:06:07 | Russ | look at drivers/char/h3600_ts.c |
| 15:06:26 | SpaceCoaster | thanks that should get me started, bit tricky this stuff. |
| 15:06:43 | SpaceCoaster | Russ: the DSP is returning data! |
| 15:08:28 | Russ | coo |
| 15:08:42 | mallum | woohoo |
| 15:10:17 | AlHazWork | SpaceCoaster: but what does it all mean?! :) |
| 15:11:36 | SpaceCoaster | AlHazWork: it means we are close to flashing lights, happy tones, speaker, etc. |
| 15:12:06 | AlHazWork | SpaceCoaster: I know, I was being silly |
| 15:12:50 | SpaceCoaster | oops, sorry, bit intense today |
| 15:13:29 | AlHazWork | s'alright |
| 15:13:30 | scanline | is back (gone 03:15:47) |
| 15:14:54 | prpplague | is there a channel for arm developers or embedded developers on openprojects.net? |
| 15:15:21 | mallum | prpplague: theres the mailing lists via arm.linux.org.uk |
| 15:17:58 | prpplague | mallum: ya already on that |
| 15:19:37 | mallum | prpplague: me too |
| 15:20:55 | prpplague | i'm trying to surround myself with "arm", in the hopes that some off the info with rub off on me |
| 15:24:51 | mallum | prpplague: hopefully my cat board is waiting for me at home |
| 15:25:56 | prpplague | mallum: i'd like to know how you like that board, i've looked at it a couple of times, but couldn't find anyone with first hand experience using it |
| 15:26:31 | GPSFan | prpplague: me too, there is something about the folks working on Tux, they like Red Drawf, Strange Brew, & StrongArms. |
| 15:27:38 | prpplague | GPSFan: it does seem that way doesn't it |
| 15:28:23 | GPSFan | prpplague: yea, a real sense of community developer spirit. |
| 15:32:07 | mallum | prpplague: well I guess we'll find out :) I spoke to a guy there on the phone and he said it comes with a Linux boot CD |
| 15:32:22 | mallum | prpplague: only has 2.2 kernel though - but he said a 2.4 *should* work :) |
| 15:33:28 | GPSFan | prpplague: what is a cat board? |
| 15:37:32 | prpplague | GPSFan: its a strongarm development board in an atx form factor |
| 15:38:10 | GPSFan | prpplague: URL? |
| 15:38:36 | prpplague | i'm looking |
| 15:38:53 | GPSFan | tnx... |
| 15:43:59 | collord | anyone know of hacking on the ceiva photo frames (arm) ? |
| 15:52:38 | SpaceCoaster | woohoo, DSP alert, just made the mute and speaker lights flash or maybe blink!!! |
| 15:52:57 | AlHazWork | woo |
| 15:54:35 | prpplague | collord: mine should be here today! |
| 15:57:38 | collord | prpplague: good luck... i wonder if the jtag is available on that hardware |
| 15:57:56 | collord | prpplague: but they're cheap enough now it's low risk |
| 15:59:53 | prpplague | collord: the maverick processor seems to be well documented and acording to some info i got on the units the jtag solder points are suppose to be available |
| 16:00:33 | collord | prpplague: you ordered from compgeeks.com ? |
| 16:00:36 | prpplague | SpaceCoaster: i'll be happy when the DSP does "exterminate!exterminate!" |
| 16:00:47 | AlHazWork | I order from compgeeks.com with alarming frequency |
| 16:00:49 | prpplague | collord: bought mine off ebay |
| 16:01:28 | collord | pprplague: wonder if the ethernet is available too. $69 new on compgeeks |
| 16:01:48 | prpplague | back when i owned a retail store, i started doing biz with compgeeks when they were just 2 guys |
| 16:01:50 | AlHazWork | collord: what is? |
| 16:02:20 | collord | polaroid (ceiva rebrand) ARM-based picture frames |
| 16:02:21 | prpplague | darn! i got ripped then |
| 16:02:56 | prpplague | collord: whats it listed under? |
| 16:03:09 | collord | http://www.compgeeks.com/details.asp?invtid=PHOTOFRAME |
| 16:03:44 | AlHazWork | says "subscription to cevia network service" at the bottom |
| 16:04:26 | collord | compgeeks won't enforce that. the sub. is required for a useful device for normal people |
| 16:04:26 | AlHazWork | So what are the exact hardware specs on those? |
| 16:04:55 | prpplague | AlHazWork: the specs i got were arm720t 32meg flash 16meg ram |
| 16:05:12 | AlHazWork | prpplague: hmm, could do a lot with that |
| 16:05:21 | AlHazWork | has anyone cracked one open and taken pictures of the board? |
| 16:05:24 | collord | prpplague: that sounds high on memory... let me find a reference |
| 16:05:52 | prpplague | AlHazWork: i'll be doing that as soon as it arrives, maybe tomorrow or monday |
| 16:07:02 | prpplague | collord: i'll never forgive you for showing me how i got ripped off! |
| 16:09:05 | collord | prpplague: sorry, that's where i started researching it. don't think i would have *found* it there. |
| 16:10:02 | collord | The Cirrus Maverick 7212 is the one with the DSP... wonder why they used it? |
| 16:14:28 | prpplague | collord: they using the DSP for the modem? |
| 16:15:54 | collord | prpplague: hmmm could be. 7212 has serial though. |
| 16:17:18 | AlHazWork | prpplague: It would make outstanding kinetic art |
| 16:17:28 | AlHazWork | prpplague: Say, run an artificial life simulation on it |
| 16:17:39 | SpaceCoaster | goes to feed the chipmunks |
| 16:17:57 | AlHazWork | prpplague: or classic screen savers - think about it, flying toasters 24/7 |
| 16:18:24 | collord | wind river does brag about the software modem implementation... |
| 16:18:48 | AlHazWork | collord: in the picture frame? screw it, rip out the modem and install an rs232 serial port |
| 16:20:05 | collord | AlHazWork: that's what they implemented via 7212 onboard DSP. plague was right. |
| 16:22:52 | collord | ethernet on that makes my mouth water. i *think* memory is the constraining factor in general. |
| 16:25:26 | AlHazWork | collord: is there ethernet on it? or are you just drooling over the prospect? |
| 16:29:13 | collord | AlHazWork: doh! mixed specs. i guess IrDA ppp will have to do. |
| 16:29:46 | AlHazWork | it has IrDA? how fast? |
| 16:30:14 | collord | at this point you know as much as I. http://www.beamaverick.com/sub.cfm?CategoryID=3&CirrusProductNumber=EP7212 |
| 16:31:37 | AlHazWork | ah |
| 16:31:47 | AlHazWork | SIR is pretty slow, I'd rather just have rs232 serial |
| 16:34:02 | prpplague | Support for up to two ultra-low-power CL-PS6700 PC Card controllers |
| 16:34:02 | prpplague | Dedicated LED flasher pin from RTC |
| 16:35:15 | AlHazWork | the ps6700 is also ultra-low-performance and ultra-hard-to-implement and ultra-end-of-lifed |
| 16:35:52 | AlHazWork | you have to clock the cpu down to 18mhz to use it, for starters |
| 16:39:30 | collord | compgeeks only has 11 left. |
| 16:40:56 | collord | ...so they weren't interested in bulk hacker deal |
| 16:45:08 | AlHazWork | screams and launches a volley of ICBMs against Lineo UK |
| 17:21:10 | SpaceCoaster | AlHazWork: TuxScreen just made a happy tone, this one was yours! |
| 17:27:56 | Lenolium | SpaceCoaster: HAPPY TONE!!!!! |
| 17:29:09 | SpaceCoaster | indeedy doody! |
| 17:30:00 | Lenolium | SpaceCoaster: After I get back from lunch. I gotta get a copy of your kernel. |
| 17:30:14 | GoRK | woah no way did you hear happy tone? |
| 17:30:22 | SpaceCoaster | Gonna put together a /proc interface so that we can read/write bytes from the DSP in userspace. Then we can generate tones / flash lights etc. |
| 17:31:27 | GoRK | @!$*(@&^$)&$@ HAPPY TONE! |
| 17:32:16 | SpaceCoaster | GoRK: wanna bet? |
| 17:32:16 | SpaceCoaster | GoRK: three tones, di di dah |
| 17:32:37 | Russ | SpaceCoaster: do a char device |
| 17:32:44 | SpaceCoaster | Lenolium: I removed the ucb1200 driver to do this, didn't want any funky interference |
| 17:33:21 | SpaceCoaster | Russ: good idea, do you have a simple skeleton, or document? |
| 17:33:45 | GoRK | what about sad done? did you hear one of those? |
| 17:33:58 | Russ | the online o'reily book |
| 17:34:14 | GoRK | it woudl be funny if it said: da da da dummmmm |
| 17:34:34 | GoRK | play when it detects mother-in-law on CID |
| 17:35:13 | SpaceCoaster | Russ: might take a week to read :-) need fasttrack |
| 17:35:27 | Russ | just read that part then |
| 17:35:54 | GoRK | how about the 'writing char devices for bit nibbling interfaces HOWTO' version 5 |
| 17:37:00 | SpaceCoaster | k, the device will write to the DSP and any messages will be queued up for reading. |
| 17:38:25 | Russ | just make a read queue, and a write queue |
| 17:38:39 | Russ | the read queue is flushed on open |
| 17:38:55 | SpaceCoaster | Russ: going for lunch now, will you be around later? |
| 17:38:59 | GoRK | if you want a super simple example, the emu10k1 midi device is pretty easy to understand and it has queued reading and writing |
| 17:39:02 | Russ | off and on |
| 17:39:20 | GoRK | i hacked on that a bit and didn't find it too alien for someone who has no idea about kernel hacking |
| 17:39:35 | Russ | add_wait_queue(), utc |
| 17:39:37 | Russ | er, etc |
| 17:40:18 | SpaceCoaster | GoRK: the sad tone is a two second long fart |
| 17:40:37 | GoRK | hahaha |
| 17:41:11 | GoRK | were you able to get DTMF turned on? or does that require reading a keypush and telling the DSP to make a dtmf tone? |
| 17:41:34 | SpaceCoaster | GoRK: I was going to say the Happy Tone is Aelhaz and the sad is for you as that is what you enquired about, but thats not kind. |
| 17:41:50 | GoRK | haha |
| 17:42:26 | GoRK | a 2 second fart huh? |
| 17:42:30 | GoRK | hahaha |
| 17:43:16 | GoRK | i ordered one of those photo frames. it'll make a fun xmas present for my buddy who just got a nice new digital camera if i can get it nice and hacked |
| 17:43:29 | GoRK | or he can do it heh |
| 17:43:34 | SpaceCoaster | farts and goes to lunch |
| 17:43:45 | GoRK | SpaceCoaster: you are a beast, man |
| 17:45:24 | GoRK | i like compgeeks a bunch |
| 17:48:02 | GoRK | blah and they have token ring cards for 2 bucks today :( i had to spend $10 ea for 2 a couple weeks ago %-\ |
| 17:55:44 | SpaceCoaster | GoRK: wanna name the new driver? |
| 17:56:03 | GoRK | why dont you just call it 'eat your wheaties' |
| 17:56:42 | GoRK | or you could call it 'riki tiki tavi' |
| 17:56:44 | SpaceCoaster | sort of like the HME (happy meal ethernet)? |
| 17:57:00 | GoRK | heck yeah happy meal's are cool boxes |
| 17:58:21 | GoRK | the IC really is called wheaties, and the IC says mongoose on it so 'eat your wheaties' or 'riki tiki tavi' both would be appropriate, but probably both a little long. |
| 17:58:40 | GoRK | how about 'eat your wheaties, riki tiki tavi' |
| 17:59:06 | GoRK | /dev/eywrtt |
| 17:59:08 | SpaceCoaster | you are stretching my knowledge of US popular culture! |
| 18:00:26 | SpaceCoaster | how bout something with SPI or DSP or shannon? |
| 18:00:26 | AlHazWork | Make it something obscure |
| 18:00:35 | GoRK | eywrtt! |
| 18:00:36 | AlHazWork | like the last name of the first jock they put on the box |
| 18:00:47 | AlHazWork | (of the cerial) |
| 18:01:06 | SpaceCoaster | AlHazWork: this is probably the most tricky part, serious ideas please! |
| 18:01:29 | GoRK | ok the DSP talks to the SA1100 through the SIB right? |
| 18:01:59 | GoRK | call it sib-wheaties |
| 18:02:18 | GoRK | in line with ucb1200-ts, etc |
| 18:02:18 | AlHazWork | Hmm, Jack Armstrong, who doesn't exist |
| 18:02:20 | AlHazWork | http://www.wheaties.com/AT/index.asp?id=1 |
| 18:02:27 | SpaceCoaster | no it's a bit twiddling interface made up of GPIO lines on the Strong Arm, it's documented as SPI |
| 18:02:43 | GoRK | so /dev/sa1100-wheaties |
| 18:02:58 | AlHazWork | hm, serious. |
| 18:03:38 | AlHazWork | hmm |
| 18:04:14 | AlHazWork | shannon-wheaties sounds so dry |
| 18:04:24 | SpaceCoaster | Jack Armstrong, you wheaties knowledge is impressive, like the ArmStrong for a StrongArm! |
| 18:04:31 | SpaceCoaster | neat |
| 18:04:51 | SpaceCoaster | looks like it might be armstrong.c |
| 18:05:03 | AlHazWork | heh |
| 18:05:15 | AlHazWork | Boy, that's obscure |
| 18:05:17 | GoRK | /dev/dsp1653 |
| 18:06:00 | GoRK | haha armstrong |
| 18:06:25 | SpaceCoaster | ok, lets come up with another one, then we can vote! |
| 18:06:51 | SpaceCoaster | maybe just wheaties.c |
| 18:07:11 | GoRK | it should probably just be called wheaties |
| 18:07:17 | mallum | what are we voting on ??? |
| 18:07:20 | GoRK | i mean.. that's the name of the device |
| 18:07:28 | GoRK | mallum: what the DSP driver should be named :) |
| 18:07:35 | GoRK | mallum: now that there is one!!!!!!!!!!!! |
| 18:07:39 | SpaceCoaster | the name for DSP driver, it's singing today! |
| 18:08:03 | mallum | ???? whats singing mean ....... |
| 18:08:15 | GoRK | happy tone! |
| 18:08:24 | mallum | wow cool !!!! |
| 18:08:25 | prpplague | webejammin.c |
| 18:08:36 | SpaceCoaster | and sad tone and flashing lights.. |
| 18:08:44 | SpaceCoaster | prpplague: lol |
| 18:08:52 | GoRK | you got the BIG LED to come on? |
| 18:09:45 | GoRK | you know... i think im going to eat some wheaties in celebration whenever my phone first plays happy tone |
| 18:09:53 | SpaceCoaster | funnily enough no, that was what I was aiming for but the rest lit up and flashed. |
| 18:10:36 | GoRK | the big one might not be connected to the DSP .. it might be on its own GPIO pin of the sa1100 or the ucb1200 |
| 18:10:40 | SpaceCoaster | mallum: got an idea for a name, choices so far armstrong.c wheaties.c webejammin.c |
| 18:11:03 | GoRK | i think it's only fair to add dsp1650.c to that list as a possibility |
| 18:11:46 | SpaceCoaster | GoRK: I don't think so, when I reset the DSP it flashes, when I probed the GPIO the only one which made a differenc was the line which reset the DSP. |
| 18:11:52 | mallum | buzby.c ? |
| 18:12:11 | GoRK | what about the GPIO's on the ucb1200? |
| 18:12:16 | SpaceCoaster | ok, dsp1650.c is in too, buzby.c, hmm |
| 18:12:39 | mallum | heh |
| 18:13:01 | SpaceCoaster | GoRK: didn't try them, aren't they all used, contrast, backlight, brightness? |
| 18:13:17 | GoRK | SpaceCoaster: i dunno there's supposed to be 10 |
| 18:13:46 | GoRK | the big led may be the most elusive device on the phone. It may never work!!!! |
| 18:14:03 | SpaceCoaster | 1+6+3=10, on/off 0-63 and 0-7 |
| 18:14:24 | GoRK | but if it requires its own device it can be /dev/bigredled |
| 18:14:31 | GoRK | hehehehe |
| 18:14:36 | SpaceCoaster | nah, the modem is never going to work |
| 18:14:38 | SpaceCoaster | hehehe |
| 18:15:32 | SpaceCoaster | mallum: buzby.c, British Telecoms advertising mascot of the late 80s, a big yellow bird, hmmm |
| 18:17:20 | SpaceCoaster | mallum: oh i get it, doh, it's connected to the telephone, more obscure than Jack Armstrong the fictional wheaties champion. |
| 18:18:24 | prpplague | GoRK: how about /dev/redalert |
| 18:18:31 | GoRK | hehe |
| 18:18:38 | GoRK | bigredled |
| 18:19:53 | GoRK | hmm easy steps to recompile all of system from source ... mmmmm |
| 18:20:05 | GoRK | like buildroot on steroids |
| 18:20:08 | GoRK | for debian! |
| 18:22:00 | prpplague | SpaceCoaster: are documenting how you are developing this new dsp driver? |
| 18:22:06 | SpaceCoaster | ok, it's armstrong.c, bigredled.c, buzby.c, dsp1650.c, webejammin.c or wheaties.c |
| 18:22:47 | SpaceCoaster | prpplague: ROFL, we don't need no stinking documentation, we are bandits! |
| 18:23:02 | prpplague | SpaceCoaster: i like GoRK's one bigredled.c |
| 18:23:14 | ProtWork | bigredled.c? |
| 18:23:26 | ProtWork | *blink* |
| 18:23:31 | prpplague | SpaceCoaster: ohh come on, try to think of us poor strongarm wannabies |
| 18:24:13 | SpaceCoaster | prpplague: I'm not really doing a working driver more of a tool for investigation, hacking. I suspect that handling audio etc. will make it very different eventually. |
| 18:24:31 | SpaceCoaster | prpplague: ok just for you I'll put in a comment. |
| 18:24:42 | prpplague | SpaceCoaster: thats what i'm interested in |
| 18:25:27 | SpaceCoaster | prpplague: have you done any kernel hacking before? |
| 18:25:35 | mallum | SpaceCoaster: yep , when we were kids we used to hassle the operator asking to speak to buzby ..... |
| 18:25:59 | prpplague | SpaceCoaster: ya some |
| 18:26:16 | SpaceCoaster | mallum: this is turning into some weird cultural exchange |
| 18:26:40 | GoRK | wait bigredled.c is not for this driver! |
| 18:26:54 | GoRK | bigredled.c is for the seperate device that controls only the big red led |
| 18:27:32 | collord | prpplague: got ceiva yet? |
| 18:27:35 | AlHazWork | ponders paying someone in the UK to manufacture and deliver a toombstone to a certian developer with the phrase "It ought to be trivial" on it |
| 18:27:52 | prpplague | collord: heck no, fedex just came and went |
| 18:29:05 | AlHazWork | now i have to reboot. Bah. |
| 18:33:05 | SpaceCoaster | GoRK: big red light works, ignoring the info and writing FF turns everything on |
| 18:33:21 | signal11 | what is the easiest way to get the calibration utility? |
| 18:34:23 | SpaceCoaster | the lights stay on or flash for 8 seconds and then reset. |
| 18:35:02 | GoRK | signal11: how do you mean? |
| 18:35:30 | GoRK | signal11: cvs -z3 :pserver:anonymous@cvs.tuxscreen.sf.net:/cvsroot/tuxscreen co fbtuxcal |
| 18:35:36 | GoRK | err |
| 18:35:43 | GoRK | signal11: cvs -z3 -d:pserver:anonymous@cvs.tuxscreen.sf.net:/cvsroot/tuxscreen co fbtuxcal |
| 18:35:59 | signal11 | that is indeed easy. thanks |
| 18:36:59 | mallum | GoRK: have you played with the libm problems any more ? |
| 18:42:22 | GoRK | mallum: not especially. i changed the references in those unions so stuff stopped crashing and I could move on, but that's about all i did |
| 18:42:49 | GoRK | mallum: though i did manage get a fairly full perl distribution down to < 1MB of flash as i had intended :) |
| 18:43:04 | GoRK | the only thing that was missing was the debugger |
| 18:44:26 | prpplague | does anyone here actually get paid to do ARM development? |
| 18:45:10 | AlHazWork | I get paid to test arm code from time to time |
| 18:45:51 | GoRK | prpplague: i think it would be neat if someone would pay me to do that |
| 18:46:19 | mallum | GoRK: cool. Do you have a patch you could send me to stop the crashes ? |
| 18:46:59 | GoRK | mallum: no. heh. i could try making a diff tonight or tomorrow though |
| 18:47:13 | GoRK | the tree that i build my kludged libm out of is fairly out of date |
| 18:51:47 | mallum | GoRK: ok np, I can wait |
| 18:54:12 | GoRK | gotta go do some work. bbl |
| 18:55:29 | prpplague | hmm, i wonder how much trash i can accumulate on my desk before it becomes impossible to work... |
| 18:57:35 | SpaceCoaster | andersee: progress on the DSP! |
| 18:59:21 | andersee | Oh? |
| 18:59:27 | andersee | What news? |
| 18:59:56 | SpaceCoaster | yes, writing commands, reading responses, flashing lights and happy tones! |
| 19:00:07 | andersee | Wohoo! |
| 19:00:13 | andersee | Very nice |
| 19:00:20 | SpaceCoaster | indeed! |
| 19:00:29 | andersee | Can you detect button presses? |
| 19:00:59 | SpaceCoaster | Haven't tried but yes, no reason why not. |
| 19:01:51 | andersee | neeto. I suppose we will need some sort of /dev/tuxscreend to make those evens available to user space, right? |
| 19:02:06 | Lenolium | *pling* |
| 19:02:27 | SpaceCoaster | yes I can, I have a /proc device which accesses the read queue, press a button and it's full of stuff! |
| 19:02:40 | andersee | cool |
| 19:02:43 | andersee | !!!! |
| 19:03:20 | SpaceCoaster | Russ: suggested a character device, write it and it gets sent, read it and it returns the queued up info. |
| 19:03:47 | Lenolium | SpaceCoaster: You know, that is the most logical thing I've heard. |
| 19:03:54 | andersee | Right. So now we just need to write a tuxscreend to select on /dev/tuxscreen (or proc whatever) and do the Right Thing with those events |
| 19:04:15 | Lenolium | andersee: That's the easy part. |
| 19:04:25 | SpaceCoaster | andersee: would a read queue of events be suitable for you? |
| 19:08:52 | andersee | Sure. Just present a char device interface that user space can select on get events as they happen |
| 19:09:26 | SpaceCoaster | do you know how I get/choose a major device number? |
| 19:10:05 | andersee | hpa is responsible for the list |
| 19:10:15 | SpaceCoaster | hpa? |
| 19:10:41 | GoRK | SpaceCoaster: there is document somewhere that lists them. linus doesnt seem to know it exists, for some reason :) |
| 19:10:57 | SpaceCoaster | andersee: and lastly we need a name for the device/driver |
| 19:11:20 | mallum | SpaceCoaster: buzby ! |
| 19:12:06 | andersee | H. Peter Anvin -- <hpa@transmeta.com> at work, <hpa@zytor.com> For the short term, you could just use one of the unused char misc devices |
| 19:12:43 | SpaceCoaster | I liked armstrong that original fictional character on the wheaties box. But it will probably be dsp1650.c, boring. |
| 19:16:51 | GoRK | wheaties.c! |
| 19:17:28 | SpaceCoaster | I guess it is more than just the DSP, it's the whole module. |
| 19:19:46 | SpaceCoaster | GoRK: wins! |

| 19:20:19 | andersee | And you could name each function after a famous sports figure... void steve_young(int foo, char* bar) |
| 19:23:44 | Lenolium | andersee: Hey, do you know of anyplace local that has the Netgear 411? |
| 19:24:24 | andersee | Lenolium: I bought one at CompUSA, approximately at state st and I-215 |
| 19:25:19 | andersee | Lenolium: It cost like $69 I think. So it bought it to check that it worked. It did. Then I ordered one from buy.com, and returned the compusa one... |
| 19:26:03 | prpplague | andersee: netgear 411, ethernet or 802.11 ? |
| 19:26:23 | Lenolium | andersee: Ahh.. was hoping you had about 50 of them lying around so you could loan me one until I could gather up the funds to grab one myself. |
| 19:26:53 | andersee | prpplague: 10/100 ethernet |
| 19:28:12 | prpplague | i've got to find time to get my dlink cf 802.11 card working on my yopy |
| 19:32:58 | signal11 | # ./fbtuxcal |
| 19:33:00 | signal11 | Floating point exception |
| 19:33:14 | signal11 | has anyone else seen this, or is it a new problem? |
| 19:33:31 | AlHazWork | haven't seen it |
| 19:33:37 | AlHazWork | fbtuxcal works here |
| 19:33:38 | signal11 | it at least tries to unzip the graphics |
| 19:33:55 | AlHazWork | maybe you have an earlier or later snapshot of it than i do |
| 19:34:13 | andersee | signal11: change your nick and it will start working. ;-) |
| 19:34:23 | AlHazWork | [alhaz@thinmint alhaz]$ w |

| 19:34:31 | signal11 | heh |
| 19:38:34 | AlHazWork | Afternon, BZFlag |
| 19:38:56 | Lenolium | BZFlag: Do you guys have power back yet? :) |
| 19:39:21 | BZFlag | Lenolium: heh, yeah. it was out for almost 2 hours yesterday. |
| 19:40:39 | Lenolium | BZFlag: Did the ups's hold on the gateway? |
| 19:41:10 | AlHazWork | BZFlag: http://store.yahoo.com/justdeals/luctecorsil1.html <-- Orinoco Silver for $59 |
| 19:44:59 | Lenolium | AlHazWork: The only problem with those are that they are 5v |
| 19:45:04 | Lenolium | has one sitting right here. |
| 19:45:21 | AlHazWork | Lenolium: Sure, but if you've got notebooks to populate anyway . . . |
| 19:45:49 | Lenolium | AlHazWork: And, why didn't you tell me about that before I bought two off of ebay? :) |
| 19:47:04 | signal11 | ah, it couldn't open /dev/ucb1200-ts |
| 19:47:11 | signal11 | so it gave a floating point exception error |
| 19:47:31 | signal11 | weird |
| 19:47:40 | signal11 | nice looking graphics, i must say |
| 19:48:03 | collord | anyone know if there is a 3.3V prism2-based wlan card? |
| 19:48:07 | AlHazWork | Lenolium: Only found it ;ast night |
| 19:52:40 | AlHazWork | collord: Supposedly all of them are 3.3v capable |
| 19:53:12 | AlHazWork | collord: I have a Linksys WPC11 and a LeArtery LN-101 that at least show up what they are in "cardctl ident" when i plug them into the phone |
| 19:53:25 | AlHazWork | but we don't have a working wireless driver on the phone yet |
| 19:54:00 | AlHazWork | there's a hub under my couch at home, so wireless for the phone at home is useless for me, but I'm willing to test, if someone gets a driver right-way 'round |
| 19:55:36 | BZFlag | Lenolium: UPS shutdown one of the routers after about an hour. |
| 19:56:07 | signal11 | hmm, no delete key on the keyboard. |
| 19:56:16 | mallum | hmmm, I thought the orinoco's would work under 3.3v ? |
| 19:56:16 | signal11 | is there any way to simulate a right mouse click? |
| 19:57:10 | gjg | signal11: bind a keyboard key to it. |
| 19:57:51 | Lenolium | mallum: The d-link orinoco is supposidly 3.3v |
| 19:58:10 | Lenolium | mallum: But the lucent ones definitely aren't |
| 19:58:27 | mallum | hmmm, I have lucent one :( |
| 19:58:30 | Lenolium | signal11: That blank unlabeled key between 'Screen -' and 'Ctrl' would be perfect. |
| 19:58:33 | collord | AlHazWork: thanks for that command. interesting... my dlink prism2 running at 5V, linksys at 3.3V |
| 19:59:09 | Lenolium | is away: Doing Dishes. Eewww. |
| 19:59:12 | mallum | well I got iwconfig compiled against uClibc anyway, if anybody wants it |
| 19:59:34 | mallum | Dont know if it works - but it dont segfault anyway |
| 19:59:53 | AlHazWork | collord: See, that at least says that the pcmcia part of the card is powered, it's still possible the radio requires 5v |
| 20:00:44 | AlHazWork | I hear tell that wlan_ng (aka prism2_cs) works on arm, but have not tried to compile it for arm |
| 20:02:22 | AlHazWork | the script that comes with it will configure it for either ppc or x86 |
| 20:02:41 | AlHazWork | and i lack motivation, since I don't forsee placing a phone anywhere that i don't have convenient ethernet |
| 20:03:16 | mallum | yeah and I dont have the money for another wireless card |
| 20:03:22 | mallum | I dont even have an AP |
| 20:03:33 | mallum | have to run everything in Ad-Hoc |
| 20:03:50 | collord | the HostAP drivers I run for prism2 supposedly work on PPC |
| 20:08:03 | BZFlag | collord: http://www.epitest.fi/Prism2/ ? work well? |
| 20:08:38 | collord | BZFlag: yes and yes |
| 20:09:20 | BZFlag | nice. |
| 20:09:55 | mallum | collord: yeah, also also heard there were binary only AP drivers for FreeBSD and orinoco's but I've never found em |
| 20:10:22 | BZFlag | Lenolium: cept that there is no insert key either. |
| 20:10:35 | AlHazWork | Well, I took a flailing whack at cross-compiling wlan_ng and didn't get anywhere |
| 20:10:42 | mallum | I should maybe get a Prism2 card, anyone recommend a working ( with Linux ) cheap one ? |
| 20:10:42 | AlHazWork | maybe I'll look again another time |
| 20:11:05 | AlHazWork | mallum: dunno what's cheap in the uk, dlink is cheap in the US and works |
| 20:11:15 | AlHazWork | dwl-650 |
| 20:11:21 | BZFlag | I think I'd rather have scr+=ins and scr-=del |
| 20:11:37 | collord | mallum: i think everything besides this is a firmware injection |
| 20:12:02 | mallum | orinoco's are damn impossible to get in the UK |
| 20:13:20 | AlHazWork | what's the unmarked key do? anything? |
| 20:15:34 | signal11 | screen shots if anyone is interested: http://hs.knm.org/~markl/ts-001.jpg through ts-003.jpg |
| 20:16:53 | pattieja | is away: I'm busy |
| 20:17:34 | gjg | signal11: NFS root I assume? |
| 20:18:11 | signal11 | X |
| 20:18:22 | signal11 | not nfs root |
| 20:19:00 | signal11 | though nfs root might be fun to play with |
| 20:19:11 | gjg | thats KDE right? |
| 20:19:14 | signal11 | yes |
| 20:19:37 | signal11 | i'm using tux screen as just an x terminal, connecting to my red hat box |
| 20:19:59 | gjg | OH I see..you running KDE from the red hat box and displaying it on the tuxscreen. |
| 20:20:15 | signal11 | right... the reason X was invented |
| 20:20:20 | gjg | ah, werd. |
| 20:20:30 | signal11 | or at least one of the main reasons 8^) |
| 20:20:35 | gjg | Yup! |
| 20:20:44 | signal11 | runs pretty well, actually! |
| 20:20:48 | gjg | cool...I should have mine pretty soon.. |
| 20:22:28 | BZFlag | more screenshots: http://BZFlag.org/test.jpg (oh, you meant of the TuxScreen ;-) |
| 20:22:47 | SpaceCoaster | BZFlag: did you hear the DSP news? |
| 20:23:33 | BZFlag | no, I read the doc, it there more news? |
| 20:23:40 | signal11 | tim nice, what is that? |
| 20:23:50 | BZFlag | signal11: uh, bzflag? ;-) |
| 20:24:05 | signal11 | as in battle zone? |
| 20:24:15 | | i think BZFlag is TimRiker or a 3D internet multiplayer multiplatform (linux, irix, win32, etc) opensource opengl Battlezone capture the flag game at http://BZFlag.org/ debian arm linux contains a version that will run on the ipaq at like 6 fps |
| 20:24:15 | BZFlag | ibot: BZFlag? |
| 20:24:25 | SpaceCoaster | BZFlag: I have a simple driver which can flash and beep and read keys! |
| 20:24:53 | BZFlag | SpaceCoaster: sweet! got any audio out the speaker yet? |
| 20:25:29 | SpaceCoaster | BZFlag: I think that's where the beeps come from..reboot TuxScreen... |
| 20:25:48 | mallum | signal11: are you running an XServer locally or over NFS ? |
| 20:26:11 | SpaceCoaster | yes, sounds like the speaker, happy tone |
| 20:26:56 | Lenolium | is back (gone 00:27:47) |
| 20:28:00 | SpaceCoaster | BZFlag: I have updated the Wiki and more news tomorrow. |
| 20:28:51 | Lenolium | So, what's this news about the UCB1200 being able to do audio? |
| 20:29:35 | signal11 | mallum no, it only has Xfbdev |
| 20:29:47 | signal11 | and busybox & fbtuxcal |
| 20:30:50 | SilverBullet | Lenolium: UCB1200 is not doing audio only the DSP, I don't think the UCB is connected to raw audio. |
| 20:32:02 | signal11 | mallum so to answer your question, locally |
| 20:34:37 | mallum | signal11: did you build Xfbdev statucally against libc ? |
| 20:35:07 | signal11 | yes |
| 20:35:13 | signal11 | i took the lazy way out |
| 20:35:21 | mallum | signal11: do you keep changing your sig ? |
| 20:35:23 | signal11 | i could rebuild it against uclibc now i suppose |
| 20:35:27 | mallum | s/sig/nick/ |
| 20:35:31 | signal11 | heh. i used to be blzbubba |
| 20:35:39 | mallum | and before that ... |
| 20:35:48 | signal11 | i think that was it. |
| 20:35:59 | signal11 | on other servers I'm markl |
| 20:36:03 | mallum | heh |
| 20:36:05 | signal11 | but someone on this network reserved it |
| 20:36:51 | mallum | signal11: I hate the way to X-compile X , it has the x-compiler paths hardcoded |
| 20:37:04 | mallum | is not making any sense |
| 20:37:25 | signal11 | cross compiling X is a pain |
| 20:37:30 | signal11 | but it's _way_ better than it used to be |
| 20:37:53 | signal11 | ever since the ipaq came out, jim & keith and those X guys have fixed it up |
| 20:38:37 | mallum | signal11: yeah but I wish they never hardcoded the paths from /skiff |
| 20:39:18 | signal11 | ln -s is your friend. 8^) |
| 20:39:19 | mallum | signal11: ordered a cat board so hopefully this weekend I'll have daddy ARM compile box |
| 20:39:53 | mallum | signal11: you just ln -s'd it and all was ok ? |
| 20:40:11 | Lenolium | Hey, do we know how to overclock the tuxscreen? I know that sboot could do it pretty easily, but can we do it with blob? |
| 20:40:45 | BZFlag | Lenolium: it's overclocked now. |
| 20:41:09 | BZFlag | Lenolium: check the blob sources, I think it's at 194mhz or something like that. |
| 20:41:17 | Lenolium | BZFlag: So by default it's overclocked? Cool. |
| 20:41:47 | BZFlag | should be able to take it to 206 or perhaps even 221 but there are memory timing issues to resolve first. |
| 20:42:12 | BZFlag | fixing them will allow speed switches on the fly. |
| 20:42:14 | signal11 | signal11 i imagine a symlink would work... |
| 20:42:20 | signal11 | i don't see why not |
| 20:42:35 | signal11 | but i haven't done it (yet) |
| 20:43:26 | mallum | signal11: you were using the skiff X-compiler ? |
| 20:44:38 | Lenolium | BZFlag: Hey, I think 194 is fast enough... I hope I get enough money to buy a ethernet card for this thing tommorrow. |
| 20:47:25 | BZFlag | Lenolium: I'd like to get at least 206 working to be the same as the ipaq, and then get speed switching working for those folk that plan on running on battery power. drop the clock speed and save power when idle. |
| 20:47:49 | signal11 | mallum yes |
| 20:47:58 | BZFlag | should be able to drop very low, 67mhz iirc. |
| 20:48:05 | andersee | BZFlag: I added a little plug for you on http://cvs.uclinux.org/uClibc.html |
| 20:48:56 | mallum | Does anybody know what the differences are between a sa110 and an sa1100 ? |
| 20:49:34 | BZFlag | andersee: nice. you could have added lrzsz, pcmcia-cs and microwindows to the list. ;-) |
| 20:50:25 | BZFlag | mallum: one more 0? ;-) actually I'd have to check the specs. I seem to recall the 1100 has more integrated features but clock speeds were about the same etc. |
| 20:51:20 | signal11 | bzflag were you offering to load blob onto the tux screens for a few extra bucks? |
| 20:51:50 | Lenolium | signal11: I think it was aroud $25 |
| 20:52:02 | BZFlag | signal11: uh, not yet. I offer to do the flash unlock for $25 |
| 20:52:35 | signal11 | ok thanks |
| 20:52:42 | prpplague | anyone use lynx in here? |
| 20:53:15 | andersee | BZFlag: k, added those as well |
| 20:53:38 | AlHazWork | prpplague: occasionally, I like "links" better, mostly |
| 20:53:55 | Lenolium | prpplague: w3m is my preferred. |
| 20:54:46 | prpplague | i've got a html form that suppose to have "apply cancel reset" but all i get is "[BUTTON] cancel [BUTTON]" any ideas? |
| 20:56:58 | cdm | hey guys. |
| 20:57:01 | prpplague | hwody |
| 20:57:02 | cdm | got my 'screen today. |
| 20:57:13 | cdm | if I nuke inferno will the phone still work? ;) |
| 20:57:25 | cdm | and is the screen supposed to shimmer? ;) |
| 20:57:33 | BZFlag | pulse dial, ring, etc yes. |
| 20:57:48 | cdm | BZFlag: and will the speaker phone still work? |
| 20:57:55 | BZFlag | shimmer? it flickers a bit, but should not be too bad. |
| 20:58:06 | BZFlag | cdm: no speaker phone, no tone dial. |
| 20:58:17 | cdm | BZFlag: wow. That is all in the DSP huh? |
| 20:58:21 | BZFlag | yep |
| 20:58:32 | cdm | cool. |
| 20:58:40 | SpaceCoaster | cdm: the flicker is much, much less when you lose the murky gray inferno. |
| 20:59:19 | andersee | cdm: and SpaceCoaster is making much progress on making the DSP behave itself under Linux |
| 21:00:52 | cdm | oh yeah? Does the DSP boot unto itself and just needs a good talking to? |
| 21:02:30 | AlHazWork | yes, it has it's own flash and ram |
| 21:03:11 | AlHazWork | prpplague: that sounds supiciously like a broken FrontPage form |
| 21:03:43 | Lenolium | AlHazWork: How much ram does the DSP have? do we know? or is that the Serial "rom" I've heard about? |
| 21:04:13 | prpplague | AlHazWork: its a html setup page on a linksys router |
| 21:04:19 | AlHazWork | Lenolium: dunno, and no |
| 21:04:22 | AlHazWork | prpplague: hmm |
| 21:04:50 | prpplague | AlHazWork: i've done this before, but for the life of me i can't remember what i had to do to submit the form |
| 21:05:17 | cdm | I assume the DSP will have it's own onboard SRAM. |
| 21:05:36 | Lenolium | BZFlag: My friend rocky, who is picking up two tuxscreens today is on his way. :) |
| 21:06:32 | Lenolium | scanline: You awake to anwser some of my newbie questions? |
| 21:07:30 | BZFlag | Lenolium: just got off the phone with him. he's running a bit late, but coming. |
| 21:08:37 | BZFlag | serial ROM is where Inferno stores user data. it is not used for DSP booting fwict. |
| 21:09:26 | Lenolium | BZFlag: What kind of data is stored there? Calibration data and the whatnot? |
| 21:09:32 | BZFlag | ram/flash details for the DSP in the data sheet listed on LucentDSP: http://TuxScreen.net/download/dsp1650.pdf |
| 21:09:58 | BZFlag | Lenolium: calibration, phone list, callerid list, notes, etc. |
| 21:10:31 | Lenolium | BZFlag: So, all the data is stored in the serial ROM? do they have the same limited write problems as flash? |
| 21:11:51 | BZFlag | Lenolium: not sure. I have no idea how they store it there. I do know that if I do a full flash rewrite under Inferno the user data remains. |
| 21:12:21 | BZFlag | I assume that machine serial numbers are stored there too. |
| 21:13:03 | AlHazWork | the repeated use limitations on flash aren't really a "problem" they just mean you can't thrash on them like you can on a disk |
| 21:13:22 | SpaceCoaster | BZFlag: does the DSP have it's own internal flash for code? |
| 21:13:29 | Lenolium | AlHazWork: Yeah, but you know what I mean, aren't the limits like 100,000 times to write? |
| 21:13:35 | BZFlag | SpaceCoaster: yes. see the data sheet. |
| 21:13:53 | Lenolium | BZFlag: Could the user data just be stored in ram? and use the batteries to back it up? |
| 21:14:13 | BZFlag | Lenolium: something like that, yes. but that is for each block. |
| 21:14:14 | SpaceCoaster | BZFlag: do you think it is write protected, he asks hopefully? |
| 21:14:32 | BZFlag | Lenolium: could be, but they did not build it that way. |
| 21:14:34 | AlHazWork | Lenolium: Well, yeah, after a whole lot of erase cycles, some bits might get stuck |
| 21:14:44 | BZFlag | SpaceCoaster: I doubt it. |
| 21:15:20 | AlHazWork | Lenolium: My boss here used to be a QA manager at philips semiconductor, I asked him about the erase cycle limitations on flash |
| 21:15:24 | SpaceCoaster | BZFlag: I'll take triple care then. |
| 21:15:34 | AlHazWork | Lenolium: He said "We rated our flash chips at 100k because everyone else rates their flash chips at 100k" |
| 21:16:03 | AlHazWork | Lenolium: it's pretty much just like speed ratings on CPUs. They sample each batch and test the samples to see if they're up to snuff |
| 21:17:06 | AlHazWork | Lenolium: He said that most of the time, the samples were well in excess of 100k, up around 3 or 4. Occasonally they were less than 100k, so they destroyed those batches. And every now and then they'd get samples that would go into millions of erase cycles without errors |
| 21:17:46 | GoRK | SpaceCoaster: how's it going? :) |
| 21:17:53 | AlHazWork | Lenolium: I've personally never heard from anyone who started getting stuck bits on a flash device |
| 21:18:11 | AlHazWork | Lenolium: tho I'm sure people who develop flash filesystems have probably artificially created that condition |
| 21:18:58 | AlHazWork | Lenolium: You'll be fine using it like a normal disk, so long as you don't try to do anything rash like use it for swap or for a web browser cache |
| 21:20:00 | SpaceCoaster | GoRK: good, I have a null driver with read/writes. |
| 21:20:34 | SpaceCoaster | GoRK: gonna be major device 60, experimental |
| 21:20:50 | SpaceCoaster | GoRK: /dev/wheaties |
| 21:21:24 | GoRK | SpaceCoaster: Wheaties! |
| 21:21:31 | AlHazWork | Lenolium: And even then it would be a while before you had issues |
| 21:21:39 | BZFlag | SpaceCoaster: you have looked at the telephony driver? We should mirror that where possible. |
| 21:23:01 | SpaceCoaster | BZFlag: I am writing a test driver so we can investigate a bit first. |
| 21:23:30 | BZFlag | don't get me wrong, any effort is appretiated, just giving input. ;-) |
| 21:24:30 | SpaceCoaster | thanks, my first linux device driver so all input is appreciated, though I can't act on it now I will later. |
| 21:25:11 | SpaceCoaster | BZFlag: I have done other unix drivers just not in living memory! |
| 21:25:58 | signal11 | is this the dsp you're playing with? |
| 21:26:20 | SpaceCoaster | BZFlag: I worked for the oldest Unix computer company still in existence, a prize if you guess it. |
| 21:26:31 | BZFlag | at&t ? |
| 21:26:42 | signal11 | unisys? |
| 21:26:56 | signal11 | or are they history |
| 21:27:18 | SpaceCoaster | at&t would be good but it doesn't exist, unisys took our Unix port. |
| 21:27:36 | signal11 | ok how about a hint |
| 21:27:44 | SpaceCoaster | later. |
| 21:30:51 | SpaceCoaster | might actually be just the oldest in the rest of the world (non-us). |
| 21:31:49 | SpaceCoaster | goes back to his cave |
| 21:34:41 | andersee | SpaceCoaster: brittish east india company? |
| 21:49:16 | AlHazWork | I was gonna say data general but it looks like they've been borged |
| 21:50:36 | SpaceCoaster | Do you want a quote from the founder? |
| 21:50:44 | mallum | to be a Unix Company they had to of produced a Unix flavour ? |
| 21:52:34 | AlHazWork | there's always sun and sgi, they don't feel, old, tho |
| 21:53:06 | SpaceCoaster | I didn't intend this to be a tease, just accidentally said something contentious, the founders quote is at http://www.netproject.com/consultants/profiles/eddieb.htm |
| 21:54:38 | SpaceCoaster | Argue it with eddie, tell him I sent you :-) |
| 21:55:18 | BZFlag | heh, I think the likes of at&t, ibm, sgi, sun etc. would not agree. ;-) |
| 21:55:48 | boris | agree with what? |
| 21:55:52 | SpaceCoaster | yeah but you don't know eddie, they would lose the argument :-) |
| 21:57:25 | SpaceCoaster | Sun was 1982, six years later |
| 21:57:44 | AlHazWork | IBM was 1940something, dunno when they first made a unix-like OS tho |
| 21:57:52 | signal11 | speaking of eddie, i am getting the urge to play some iron maiden |
| 21:57:58 | mallum | man, Bleasdale computer systems rocks |
| 21:58:33 | mallum | the name is so much cooler than sun , sgi etc |
| 22:02:33 | mallum | ok night all |
| 22:07:07 | BZFlag | bbiab |
| 22:12:31 | as_ | Evnin all. |
| 23:09:10 | BZFlag | later |
