| 00:14:37 | prpplague | GPSFan: you alive? |
| 00:14:41 | | GPSFan was last seen on #tuxscreen 3 days, 6 hours, 41 minutes and 58 seconds ago, saying: prpplague: on J600 & J601 the pins going to the LCD are the ones labeled LDD and the GP0-9 GPIO's, that's the shortcut I took, on the Comms board b schematic, they are bussed together, rather than shown individually. I believe that shannon.c has a table telling which is which. [Wed Mar 6 17:32:43 2002] |
| 00:14:41 | prpplague | ibot: seen GPSFan |
| 00:14:56 | prpplague | [trebb]: howdy |
| 00:20:01 | GPSFan | prpplague: Howdy! |
| 00:21:00 | p2_ | hi |
| 00:21:45 | GPSFan | bbiab, time to feed the critters... |
| 00:23:03 | prpplague | GPSFan: got some power supply questions on the tuxscreen when you get back |
| 00:38:28 | [trebb] | prpplague: Howdy! |
| 00:40:27 | prpplague | [trebb]: started on making a tuxpad yet? |
| 00:41:43 | [trebb] | prpplague: well, I got linux runnig today... toying around a bit now. |
| 00:42:39 | [trebb] | I was planning to go with Qtopia, so I guess I'll have to get familiar running? |
| 00:42:46 | GPSFan | prpplague: back what's up? |
| 00:43:23 | prpplague | GPSFan: the mainboard for the tuxscreen only needs 3.3 right? the 5v is used by the dsp and the lcd panel? |
| 00:44:08 | GPSFan | prpplague: correct, Tom_W has built a development board running the core of +3.3V |
| 00:44:40 | GPSFan | prpplague: the LCD itself is 3.3V, it's the backlight that needs 5V |
| 00:45:01 | prpplague | GPSFan: has he gotten the info posted yet? i knew he was working on some stuff but didn't know if he'd gotten some additional schematics posted |
| 00:45:05 | prpplague | GPSFan: right |
| 00:45:17 | prpplague | GPSFan: that leads to one more questions |
| 00:45:36 | GPSFan | prpplague: I thought he had the schematics posted on his web site. |
| 00:46:02 | prpplague | GPSFan: there are a series of caps and resistors on comm board going into the lcd panel connector |
| 00:46:14 | prpplague | GPSFan: happen to know what those are for? |
| 00:46:28 | prpplague | GPSFan: i didn't see them on any of the schematics |
| 00:47:22 | prpplague | GPSFan: FL303-FL313 and C335-c345 |
| 00:47:31 | GPSFan | prpplague: yes, that's my fault, I believe that they are EMI filters, there are lots of signals with fast transitions going up that cable. |
| 00:48:39 | prpplague | GPSFan: hmm, should i worry about that on my initial test board? |
| 00:50:09 | GPSFan | prpplague: probably not, unless you fing that you get a lot of "sparklies". They can also serve to stabalize the impedance of that "long" cable for the controller. I don't believe that the SA1100 has very powerful drive on the LCD pins. |
| 00:50:20 | GPSFan | s/fing/find |
| 00:50:46 | [trebb] | time for bed... seeya |
| 00:51:01 | prpplague | GPSFan: ok thanks, i think i'll see how my initial board turns out before addressing the emi stuff |
| 00:52:27 | GPSFan | prpplague: ok, make sure that the clocks run with a parallel ground wire. TFT's are especially sensitive, DSTN less so. |
| 00:53:36 | prpplague | GPSFan: ok thanks |
| 00:53:44 | GPSFan | ;>) |
| 00:53:52 | prpplague | GPSFan: i'm going to try and get the serial console running first |
| 00:54:07 | prpplague | GPSFan: then once i get that going move on the a the lcd |
| 00:54:47 | GPSFan | prpplague: I got it so I could send & receive. I used the RTS/CTS driver/receiver that's on the primary port. |
| 00:56:43 | prpplague | GPSFan: you lost me... are you talking about the serial console? |
| 00:56:59 | GPSFan | prpplague: the second serial port. |
| 00:57:20 | prpplague | GPSFan: ohh |
| 00:58:24 | GPSFan | prpplague: Tangent & I worked out how to do it a while ago, he got his working to run his home automation system, I just got around to getting mine running the other day. |
| 00:58:54 | prpplague | GPSFan: cool |
| 00:59:43 | GPSFan | I want to connect my 2nd port to a Dallas one wite weather station. I have it running on my CerfCube. under glibc. still fiddling around with compiling it under uClibc. |
| 00:59:55 | GPSFan | s/wite/wire |
| 01:00:12 | prpplague | nice |
| 01:01:27 | scanline | notices #tuxscreen |
| 01:01:30 | scanline | hi GPSFan! |
| 01:01:52 | GPSFan | prpplague: haven't had much time to work on it lately, had an ISP problem for the last week, finally fixed yesterday. |
| 01:02:00 | GPSFan | hi scanline: |
| 01:03:19 | prpplague | GPSFan: ya well i really should be working on some of my other more profitable projects, but i'm playing around |
| 01:04:47 | GPSFan | prpplague: I define palying around as doing cool interesting stuff, that reduces time when you have to do the same thing for a customer. |
| 01:05:19 | prpplague | true |
| 01:06:09 | GPSFan | prpplague: so playing around can be rewarding, esp. if followed by a good pint or two! |
| 01:07:35 | prpplague | lol |
| 01:07:43 | prpplague | amen |
| 01:07:48 | GPSFan | mmm... beer |
| 01:08:51 | GPSFan | scanline: What have you been up to lately, how's pico going. |
| 01:09:10 | prpplague | GPSFan: well i have the j600-j601 connector built and the power supply just need the max3232 chips |
| 01:09:25 | scanline | GPSFan: I've been doing a lot of picogui development lately, for fun and for profit |
| 01:09:42 | GPSFan | prpplague: maxims sample program works well. |
| 01:09:57 | scanline | GPSFan: I just got around to writing an updated FAQ :) |
| 01:10:04 | prpplague | GPSFan: ya i'm going to give them a call monday |
| 01:10:10 | scanline | well, i should go get some dorm food before they close... |
| 01:10:13 | | scanline: bugger all, i dunno |
| 01:10:13 | scanline | ibot: dorm food? |
| 01:10:31 | | scanline: huh? |
| 01:10:31 | scanline | ibot: dorm food probably won't kill you... but no guarantees |
| 01:10:34 | GPSFan | scanline: I'll go read it, mmm... dorm food ...yuck |
| 01:10:43 | | scanline: huh? |
| 01:10:43 | scanline | ibot: dorm food isn't quite poisonous |
| 01:10:46 | scanline | bah... |
| 01:10:51 | | PicoGUI faq is at http://picogui.org/wiki/view/Main/FAQ |
| 01:10:51 | scanline | ibot: PicoGUI faq? |
| 01:10:57 | scanline | is away: ZzZzZzzzzz |
| 01:10:59 | scanline | oops |
| 01:11:05 | GPSFan | thanks ibot. |
| 01:11:06 | scanline | is away: foodlike stuff, i think |
| 01:12:24 | GPSFan | prpplague: if you don't see what you need on the web site, call, they will often send you just what you need ( the right package that is) |
| 01:13:39 | prpplague | GPSFan: i'm only doing dev work right now, are they gonna what me to be say i'm going make x number of boards? |
| 01:15:21 | GPSFan | prpplague: several years ago I needed one of their dc-dc dhips, tried to buy 100 or so for production, got told 12 weeks. Then ther rep said that their sample pool had plenty, so just order a lot of samples. 6 months after the end of the project I was still getting samples of that chip in the mail. |
| 01:15:52 | prpplague | GPSFan: cool |
| 01:16:46 | GPSFan | prpplague: in the past they have bent over backwards to get me the samples I needed. ymmv, but worth a try. |
| 01:18:43 | GPSFan | prpplague: Samtec is another good source of cable and connector samples. I just received some FFSD .05" cables day before yesterday. |
| 01:32:11 | prpplague | GPSFan: hey, would a 7.2v rechargable battery do ok with a 5v and 3.3v regulator to run the tuxscreen? |
| 01:32:53 | GPSFan | prpplague: I'd use a switcher, but a linear should be ok for testing. |
| 01:33:38 | GPSFan | use LDO for the 5V, since the 7.2V will probably sag. |
| 01:33:58 | prpplague | GPSFan: don't suppose you could recommend for the 3.3v? |
| 01:34:27 | GPSFan | prpplague: switcher of linear? |
| 01:34:53 | prpplague | GPSFan: switcher |
| 01:37:23 | GPSFan | bbiab |
| 01:37:36 | prpplague | TomW: ? |
| 01:38:26 | GPSFan | prpplague: http://www-s.ti.com/sc/ds/78ht233.pdf samples available... off to feed, mmm... real food & beer... |
| 01:39:05 | prpplague | GPSFan: thanks |
| 01:39:47 | GPSFan | prpplague: bypass it well or it will sing loke a bigd! |
| 01:39:55 | GPSFan | s/bigd/bird |
| 01:40:03 | prpplague | lol |
| 01:40:07 | prpplague | will do |
| 02:50:13 | | GPSFan was last seen on #tuxscreen 1 hours, 10 minutes and 18 seconds ago, saying: s/bigd/bird [Sun Mar 10 01:39:55 2002] |
| 02:50:13 | comMan | ibot: seen GPSFan |
| 02:56:25 | prpplague_home | GPSFan: if you get back around, got one more question that pop'd up on the drive home |
| 03:11:18 | GPSFan | prpplague_home: back, ask away, good food & beer... |
| 03:43:38 | prpplague_home | GPSFan: you said the lcd upper data was gpio0-7 on the tuxscreen |
| 03:44:17 | prpplague_home | GPSFan: why did they not use some of the gpio's 11-27 which share an irq rather than take up gpio's 0-7 which have individual irqs |
| 03:44:41 | prpplague_home | GPSFan: you don't need irqs for an lcd interface, right? |
| 04:03:44 | GPSFan | prpplague: the GPIOs used for the LCD interface are GPIO 2:9, and are pre defined by the SA11x0 for that purpose, if I said 0:7 I meant to say 2:9. |
| 04:04:43 | prpplague_home | ohh |
| 04:05:06 | prpplague_home | GPSFan: so when you use an lcd, you loose the use of 8 gpio's? |
| 04:05:27 | prpplague_home | GPSFan: unless you use some sort of lcd controler interface? |
| 04:06:09 | GPSFan | the schematic for the Comm board B shows GPIO1 going to the LCD bus, that's an error I have yet to correct. |
| 04:07:33 | GPSFan | prpplague: correct, if you an LCD that needs all the bits, like most DSTN and all TFTs |
| 04:08:11 | GPSFan | an external LDC controller will solve that problem, at the cost of cost, power, & software. |
| 04:09:27 | prpplague_home | GPSFan: ok, gotcha |
| 04:10:01 | prpplague_home | GPSFan: thanks, i was wondering about that, i need to add that info to my gpio notes |
| 04:11:17 | GPSFan | page 11-17 of the Intel version of the SA1100 developers manual 278088.pdf |
| 04:12:32 | prpplague_home | GPSFan: thanks, i'll give it a read |
| 04:13:13 | prpplague_home | GPSFan: you'll have to forgive my uneducated questions, taking a stab at working with arm hardware for the first time |
| 04:14:14 | GPSFan | chapter 11.7 is all about the LCD controller. lots of good stuff |
| 04:15:10 | GPSFan | prpplague: np, I have a much worse time with software than most of you guys have with hardware. ;>( |
| 04:15:38 | GPSFan | but if I don't try it I won't learn it. |
| 04:16:03 | prpplague_home | GPSFan: well just remember, i'm here to share what little knowledge i have anytime |
| 04:16:20 | GPSFan | Thanks! |
| 04:19:41 | prpplague_home | GPSFan: what do you think about using a 240x64 lcd panel on a SA? |
| 04:20:39 | GPSFan | is it a graphic lcd, or one with a built in controller? |
| 04:21:05 | prpplague_home | GPSFan: it has a built in controler |
| 04:21:30 | prpplague_home | GPSFan: i also am looking at this - http://www.earthlcd.com/pdalcd.htm |
| 04:21:43 | GPSFan | looking... |
| 04:22:22 | GPSFan | that link points to a 320 x 240 |
| 04:22:42 | prpplague_home | GPSFan: ya thats another one i'm looking at |
| 04:22:45 | prpplague_home | GPSFan: $39 |
| 04:23:09 | prpplague_home | GPSFan: and if i understand the docs, only requires a 3.3v source |
| 04:25:51 | GPSFan | http://www.zlcd.com/downloads/lm24014h.pdf is a 5V device that also needs 18V, http://www.earthlcd.com/pdalcd.htm is a 3.3V device that also needs 23V for bias. |
| 04:26:43 | prpplague_home | GPSFan: ahh, guess i didn't read it right |
| 04:27:52 | GPSFan | the other voltage is typically negative WRT the LCD ground, and is often used for contrast adjustment. |
| 04:28:31 | GPSFan | page 7 of the Sharp spec. |
| 04:29:58 | prpplague_home | GPSFan: what about - http://www.seiko-usa-ecd.com/lcd/products/graphic_mods/g242cx5r1a0.html |
| 04:33:45 | GPSFan | The seiko requires VLC which is negative WRT LCD ground, again for bias/contrast, Pin 19 of the connector .pdf |
| 04:34:59 | GPSFan | The Samsung fro earthlcd.com needs a positive bias, which may be easier to generate. that panel sould be controllable directly from the SA1100's LCD controller. |
| 04:36:17 | GPSFan | the bias voltage isn't usually a big deal to generate. it is usually really low current. however it may need to have a temperature variable component to compensate for temperature changes in the LCD itself. |
| 04:39:00 | prpplague_home | GPSFan: hmm, this char lcd 4x40 is looking kinda fun right now!lol |
| 04:41:24 | GPSFan | many of the character based displays have a built in bias generator, so all they need is 5V, then again some don't: http://www.mpja.com/product.asp?product=14117+OP |
| 04:42:32 | prpplague_home | GPSFan: i'm not sure which mode i have (i've got about 30 in storage) |
| 04:43:18 | GPSFan | do you have a mfr P/N? |
| 04:43:38 | prpplague_home | GPSFan: i'll have to pull one tomorrow and check them out |
| 04:44:24 | GPSFan | ok, pass along the mfr & P/N and I'll see if I can dig up a datasheet, that will tell. |
| 04:45:46 | GPSFan | this is a good source for cheap LCD's, mostly B&W or char based. http://www.allelectronics.com/cgi-bin/category.cgi?category=365&type=store |
| 04:46:52 | prpplague_home | GPSFan: ya i've bought from allelectronics before, but i've not checked them out for lcd's |
| 04:48:52 | prpplague_home | http://www.allelectronics.com/cgi-bin/category.cgi?category=365&item=LCD-58&type=store |
| 04:48:58 | prpplague_home | that one looks interesting |
| 04:54:42 | GPSFan | it does, it's sort of smart, needing a parallel type of interface, but it needs a -18V supply, at what someone said is a bit of power. |
| 04:55:01 | prpplague_home | GPSFan: yep |
| 04:55:11 | GPSFan | I'm off to bed, night all... |
| 04:55:26 | prpplague_home | GPSFan: thanks for the help |
| 04:55:31 | GPSFan | ;>) |

| 11:03:35 | fontenot | ibot: seen andersee |
| 11:12:22 | p2_ | anyone here using the tuxscreen in europe ? |
| 11:12:52 | fontenot | several people are, but not me |
| 11:13:01 | fontenot | pokes Tangent |
| 11:13:02 | Tangent | me |
| 11:13:16 | fontenot | heh, does the UK count as europe? ;-) |
| 11:13:49 | p2_ | Tangent: how about the powersupply ? Do you have to build your own, or can you use the US powersupply with a 230V to 120V transformer ? |
| 11:13:49 | Tangent | fontenot : Just barely |
| 11:14:03 | Tangent | p2_ : I have a 230/120 transformer |
| 11:14:15 | p2_ | fontenot: enough for my purposes, ie a country where mains power is 230V/50hz AC :) |
| 11:14:45 | p2_ | Tangent: and does the phone part work ? or does it really need a 120Hz signal on the PFI pin ? |
| 11:14:56 | fontenot | well looks like you are in luck then :-) |
| 11:15:06 | Tangent | p2_ : The phone part works, but Caller ID didn't... |
| 11:15:14 | Tangent | p2_ : I know nothing about any PFI pin |
| 11:15:48 | p2_ | Tangent: ok, I guess callerid is a country specific thing |
| 11:16:02 | p2_ | Tangent: http://tuxscreen.net/wiki/view/Users/PFI :) |
| 11:16:11 | Tangent | p2_ : Yep.. I know that the UK invented it's own standard for Caller ID |
| 11:17:02 | Tangent | p2_ : Haven't run into any problems with PFI... Tuxscreen has been up and running fine since september |
| 11:17:24 | p2_ | Tangent: belgium did too. standards are nice, there so many to choose from |
| 11:17:34 | p2_ | Tangent: ok. just to know |

| 18:12:39 | prpplague | kinda quite |
| 18:27:04 | prpplague | anyone know whats up with openhardware.net ? |
| 18:28:01 | | TomW was last seen on #tuxscreen 3 days, 20 hours, 21 minutes and 28 seconds ago, saying: is away: I'm busy [Wed Mar 6 22:06:33 2002] |

| 18:58:38 | [trebb] | prpplague: do you know if familiar-based images exist for the tuxscreen? |
| 18:59:04 | prpplague | [trebb]: i don't know, i rarely use popular dists |
| 18:59:45 | [trebb] | i see... I need something with c++ library suport. |
| 19:00:33 | [trebb] | i guess I'll have to fidle around myself :) |
| 19:00:37 | prpplague | [trebb]: yep |
| 19:18:33 | pmisfit | c++ library support is something that andersee is working on right now, no? |
| 19:19:34 | pmisfit | i don't remember if he finished with it or not. if not, then you'd probably have to run a glibc-based disty via nfs. |
| 19:20:38 | prpplague | pmisfit: yes that is correct, but there are still a few issues |
| 19:20:56 | prpplague | pmisfit: something should be available in a couple of weeks or less |
| 20:03:16 | [trebb] | pmisfit: yes, i think I'll do that, but from cf. is andersee working with uClib? anyway, i guess i'll have a look at the familiar stuff for now. or are there any recommended alternatives? |
| 20:04:22 | prpplague | [trebb]: andersee is the maintaner of busybox, uclibc and tiny login |
| 20:07:05 | [trebb] | prpplague: oh... :) |
| 20:08:24 | | i think andersee is running into "issues" and hence fixing uclibc bugs. |
| 20:08:24 | prpplague | ibot: andersee |
| 20:17:01 | [trebb] | later.. |
| 21:39:17 | Donwulff | BZFlag: I think it'd be fair to warn on the TuxScreen sales-page that PayPal's capped at $100 dollars of payments for the first month in most cases. |
| 21:39:56 | Donwulff | Anyway, I couldn't find on the WiKi anything too definite on the color-depth & supported memory on the device, what's the latest on those? |
| 21:42:11 | BZFlag | 640x480x8 |
| 21:42:30 | BZFlag | the panel may support more, but that's the mode that Inferno and Linux use. |
| 21:42:32 | Donwulff | That's colors, not bits, or gray-scales? |
| 21:42:39 | BZFlag | bits. |
| 21:42:43 | Donwulff | Ah. |
| 21:42:58 | BZFlag | just as 640x480x24 is bits. |
| 21:43:57 | Donwulff | Thanks. How about the memory. The flash is un-expansible? And how far can the RAM go currently? |
| 21:48:29 | Donwulff | works in a project developing prototype XML-browser with future information appliances etc. in mind, which happen to be fairly hard to come by right now. Since we've used the iPAQ with Familiar so far, it would appear the TuxScreen would be good match for prototyping, but I need to convince the decision-makers of it ;) |
| 21:49:12 | Donwulff | I assume it's usable to such a degree right now, ie. running Linux software without too many hitches? Or is it still in need of OS level work to be usable? |
