| 02:22:27 | Tangent | wonders if there's any life here |
| 04:50:28 | Tangent | goes to bed.. night all |
| 07:42:48 | CMC0619 | hey all. |
| 14:09:59 | fontenot | is tuxscreen backlit? |
| 14:11:22 | MicroChip32 | yes |
| 14:11:30 | MicroChip32 | ummm i think |
| 14:11:38 | MicroChip32 | its visible in the dark |
| 14:11:44 | Tangent | Yeah.. it is backlight |
| 14:11:48 | Tangent | backlit even |
| 14:14:15 | fontenot | cool |
| 14:14:40 | fontenot | do we have backlight brightness control as on the ipaq? |
| 14:25:18 | Tangent | fontenot : I think we have contrast and brightness controls.. but I'm not sure we've got an app to twiddle the right ioctls at the moment |
| 14:26:35 | fontenot | Tangent: do you know if the display is active matrix? |
| 14:26:44 | Tangent | fontenot : I think it's DSTN |
| 14:28:44 | fontenot | ah, ok, what's viewing angle like? |
| 14:30:52 | Tangent | fontenot : Side to side, it's very good.. up and down, it's not so hot.. but the screen tilts back and forth... just not quite enough |
| 14:31:07 | fontenot | cool |
| 16:55:23 | Tangent | goes off to watch scrapheap challenge |
| 16:58:47 | SteveD | too |
| 17:26:38 | MicroChip32 | gets comfortable watching football |
| 17:28:12 | SpaceCoaster | rushes to television and then realises he's on the wrong continent |
| 17:32:12 | MicroChip32 | kicks SpaceCoaster a little ROUND BLACK & WHITE ball |

| 17:46:48 | Error403 | Hi all |
| 17:47:53 | SpaceCoaster | GPSFan: you around. to talk me through connecting by shanip to my tuxphone? |
| 17:48:02 | Error403 | Is there any chance that I can put familiar linux on my tuxscreen without having to have a flash card or network card? |
| 17:48:14 | SpaceCoaster | s/tuxphone/TuxScreen/ |
| 18:02:28 | Tangent | SpaceCoaster : I can do that |
| 18:02:41 | Tangent | SpaceCoaster : I've got mine all hooked up |
| 18:04:01 | SpaceCoaster | Tangent: thanks, i thought you were busy with the tv, junkyard wars? |
| 18:04:13 | Tangent | SpaceCoaster : Yeah.. but that's finished now |
| 18:04:35 | SpaceCoaster | Cool, I see, http://tuxscreen.net/download/schematics/j500.jpg which is pretty clear |
| 18:04:53 | SpaceCoaster | Do I really need three grounds frame, signal and gnd? |
| 18:05:07 | Tangent | SpaceCoaster : Yeah.. that's the connections on the bottom of the i/o board.. the other one is http://www.tuxscreen.net/download/schematics/ucb.jpg |
| 18:05:15 | Tangent | SpaceCoaster : No.. all grouhds are the same thing |
| 18:06:52 | SpaceCoaster | Tangent: ok, the ucb.jpg is less clear, which pins are which? |
| 18:07:16 | Tangent | SpaceCoaster : The dot on the corner of the chip is pin 1... the red circle on the left is around pins 8&9 |
| 18:07:24 | GPSFan | SpaceCoaster: Tangent: howdy, just finished lunch, Tangent go ahead and talk SpaceCoaster through it you are doing fine. |
| 18:07:35 | Tangent | SpaceCoaster : pin 10 is speaker power and needs a connection to 3.3v.. hence the yellow line |
| 18:07:53 | Tangent | SpaceCoaster : The other red circle is pins 20&21 |
| 18:08:10 | Tangent | Gotta nip out for 5 mins.. back real soon.... (Garage run for more Red Bull) |
| 18:08:15 | SpaceCoaster | ok I'm using the schematic which has no connection for spkr- |
| 18:09:54 | GPSFan | SpaceCoaster: did you do a PCB of just wire it up on a piece of perf-board? |
| 18:10:58 | prpplague | whats everyone working on today? |
| 18:11:09 | SpaceCoaster | perf board |
| 18:12:21 | SpaceCoaster | GPSFan: will it matter if I just use the GN near the T/R OUT +- |
| 18:12:27 | SpaceCoaster | s/GN/GND/ |
| 18:12:54 | GPSFan | SpaceCoaster: that one is fine, you also don't need the spkr- lead. |
| 18:13:08 | prpplague | SpaceCoaster: makin a shanip board? |
| 18:13:24 | SpaceCoaster | prpplague: correct |
| 18:13:45 | SpaceCoaster | GPSFan: I am using you 2.5 pdf |
| 18:14:11 | GPSFan | prpplague: I'm just relaxing after lunch befor heading out for another load of hay for the critters. |
| 18:14:38 | GPSFan | SpaceCoaster: yeah, it shows spkr- connected to the connector, but unused. |
| 18:15:14 | SpaceCoaster | GPSFan: oh, the 1uF capacitor, I got a tantalum and it has + sign is it polarised? |
| 18:15:25 | SpaceCoaster | GPSFan: will it work? |
| 18:16:44 | GPSFan | SpaceCoaster: it should, to be correct, you should measure the DC component on T/R OUT- , should it be + then connect the + of the cap there, |
| 18:18:37 | SpaceCoaster | the 1uF is connected to T/R OUT +, I have it connected with the + on the capacitor to R4, is that reasonable? |
| 18:22:46 | GPSFan | SpaceCoaster: the problem with using electrolytics in a situatiion where there is no DC bias in the circuit is that innards of the cap do not get properly polarized, and do not achieve the desired capacitance. I'm sorry I looked at the schematic to quiclky and thought it was connected to T/R OUT+, that's the place to look for the DC bias. |
| 18:24:04 | SpaceCoaster | so probably no good, is the technical summary? |
| 18:25:34 | GPSFan | SpaceCoaster: correct, if there is + voltage on the T/R OUT+ pin it should be connected to the + end of the cap. |
| 18:27:16 | SpaceCoaster | GPSFan: ok, so i, after lunch, I reassemble this beast and use a meter to measure the volts that might help to determine which way round, if any, this should go? |
| 18:28:10 | GPSFan | SpaceCoaster: yep, that should do it, and if there isn't any DC then either way should be ok. |
| 18:28:17 | Tangent | comes back |
| 18:30:55 | SpaceCoaster | GPSFan: thanks, and to you too Tangent, gonna eat lunch, bbiab |
| 18:36:07 | prpplague | goes for more sinus medicine |
| 18:39:48 | prpplague | hmm, cough drops and coffee, what a mix |
| 18:41:21 | Tangent | prpplague : Yeah... that sounds like good stuff... can you still feel your feet? |
| 18:43:53 | prpplague | Tangent: feet are fine, its my eyes i'm worried about...., feel's like someone scraped them out with a spoon and pushed them back in |
| 18:44:51 | Tangent | prpplague : Flu? |
| 18:45:25 | prpplague | Tangent: sinus, big cold front moved through friday, big weather change |
| 18:45:54 | prpplague | thursay high of 89f friday high 53f |
| 18:47:20 | prpplague | ok guys, can someone answer a question, i'm not sure i understand why all i/o from userland apps are memory mapped |
| 18:47:56 | prpplague | if i'm accessing a gpio or an address for pcmcia, why do i have to map a memory page to do the access? |
| 18:49:48 | prpplague | anyone? |
| 18:50:08 | GPSFan | prpplague: all the I/O etc on an SA1100 is memory mapped. |
| 18:50:48 | GPSFan | prpplague: there is no seperate I/O space like on an x86 |
| 18:51:43 | prpplague | GPSFan: i just don't understand the reasoning behind using a memory mapped i/o, |
| 18:51:51 | prpplague | GPSFan: let's see... |
| 18:52:12 | prpplague | GPSFan: i have a device at 0x30000000 that i want to talk to |
| 18:52:45 | Tangent | GPSFan : I've been looking at the schematic for j602 (unpopulated connector).. Have you any idea what it's there for, or is it destined to become something fun like a General purpose I/O port for use to hack on? |
| 18:52:48 | prpplague | GPSFan: i make a request to the mmu to provide a virtual address to represent the io address of 0x3000000? |
| 18:53:41 | prpplague | GPSFan: from that point forward the virtual address provided by the mmu is used to read/write to the physical address of 0x3000000? |
| 18:54:22 | GPSFan | prpplague: I think that's the way it works. if ther were no mmu, it would be simpler. |
| 18:55:26 | prpplague | GPSFan: so even though i'm requesting the same physical address space, i may not get that same virtual address space everytime, it will depend on what other i/o's have been requested? |
| 18:56:54 | GPSFan | Tangent: j602 might be a "test connector" I also saw a reference to an ISA interface, in one of the shannon pieces of source code. since there are only 9 bits of address, and one nCS line, it might look like a paralled interface if you were to add some latches, etc. there is also the GPIO that could serve as an interrupt to the CPU. |
| 18:57:31 | Tangent | GPSFan : I've seen ISA cards hooked up to PIC microcontrollers before.. I expect we could hook an ISA card up if anyone was really desperate |
| 18:57:39 | prpplague | GPSFan: the fact that having a mmu usually means you have true multi-tasking enviroment, does this mean that by using virtual addresses rather that physical address that multiple applications can use the same physical device without creating conflicts, hence the memory MANAGEMENT comes into play? |
| 18:59:30 | GPSFan | prpplague: I'm lost now, if multiple processes are using the same hardware, there needs to be some sort of lock so porcess 1 doesn't read data requested by process 2. |
| 19:00:52 | prpplague | GPSFan: isn;t that the purpose of the mmu to manage the i/o read/writes? |
| 19:02:34 | prpplague | GPSFan: process has made a request for info to a virtual address, shortly there after process makes a request, the mmu already knows process 1 has made a request, and waits for the first response and forwards it to processor 1 and then forwards process 2's request to the physical port |
| 19:02:58 | prpplague | GPSFan: process 1 has made a request for info to a virtual address, shortly there after process 2 makes a request, the mmu already knows process 1 has made a request, and waits for the first response and forwards it to processor 1 and then forwards process 2's request to the physical port |
| 19:03:03 | prpplague | oops |
| 19:04:12 | prpplague | GPSFan: instead of process locks on a single physical address the mmu intercepts the requests by using virtual address |
| 19:04:45 | prpplague | and handles the "locking" by keeping track of whos asking for what |
| 19:04:58 | prpplague | GPSFan: does that sound logical? |
| 19:05:25 | prpplague | GPSFan: i'm just trying to understand this myself |
| 19:07:25 | prpplague | that make sense to anyone else? |
| 19:07:42 | GPSFan | prpplague: I always thought that the MMU allowed the OS to map and allocate memory such taht different physical memory may be made to appear contiguous. I prpbably need to re-read the SA1100 and or the ARM architecture manuals. My view of an MMU came from experience with the Z8000 years ago, and it didn't do much more than logical to physical translation. |
| 19:14:24 | prpplague | GPSFan: ok did some quick reading... |
| 19:15:52 | prpplague | GPSFan: the cpu has a limited number of address spaces that it can access, but by using these as virtual spaces an unlimited number of physical spaces can be access on the limited number of cpu addresses |
| 19:16:20 | prpplague | GPSFan: sound closer to what your idea of mmu was? |
| 19:17:53 | GPSFan | prpplague:it does at that. |
| 19:20:10 | prpplague | GPSFan: so i see now, the ARM gods didn't want to take up valuable address space be defining a set of physical i/o address, instead they've used the i/o's just like memory there for maximizing the amount of ram and peripheral devices that can be attached to the system |
| 19:22:20 | GPSFan | prpplague:yes, but there are specific memory address ranges dedicated to DRAM, SRAM/FLASH. |
| 19:23:09 | prpplague | like the default physcial address of 0x00000000 being the block in flash to execute on a reset irq |
| 19:23:41 | prpplague | or the physical addresses where sleep pointer info is stored |
| 19:25:08 | GPSFan | prpplague: or where you setup the memory controller, but not how you setup the MMU, it has dedicated instructions. |
| 19:26:26 | prpplague | GPSFan: ok things are a little clearer now, hmm i guess a standard pcmcia controler chip would have some form of a mmu to manage access to pcmcia cards |
| 19:28:28 | as_ | Evnin all. |
| 19:29:10 | prpplague | howdy as_ |
| 19:29:27 | GPSFan | prpplague: the SA1100's builtin PCMCIA controller is also memory mapped, but something like a Cirrus 6720 was all i/O for x86 architectures, the 6722 was a PCI device. aren't you using an elf, and doesn't it have a 6720? |
| 19:31:24 | prpplague | GPSFan: ya i'm using the elf and it has a 6722 |
| 19:32:42 | prpplague | GPSFan: just reading the cl6722 manual, they don't call it a mmu function, they refer to it as "memory map windowing" |
| 19:33:39 | GPSFan | prpplague: memory map windowing is so that PC cards that are memory based can be "mapped" to appear in the CPU's address space. |
| 19:34:50 | GPSFan | prpplague: PC cards can be I/O, memory, or a combination. all must have the configuration tuples memory mapped though. |
| 19:35:24 | GPSFan | prpplague: do yu have a copy of th PCMCIA spec? |
| 19:35:32 | as_ | Hiya prp. |
| 19:35:46 | prpplague | GPSFan: negative, i've not gotten around to spending the $$ |
| 19:36:15 | prpplague | GPSFan: beer and hookers have been higher on the list....lol |
| 19:36:22 | as_ | Might be good to search, just in case someone has it online. |
| 19:36:37 | as_ | I'll try a search now. |
| 19:37:22 | GPSFan | prp, ah, I know the feeling, I've managed to get a hold of my old copy, and can excerpt sections if need be. but I'm off to get another load of hay, so I'see you all later. |
| 19:37:42 | as_ | Do we know the actual spec name? Like ISOblah? |
| 19:38:01 | prpplague | GPSFan_away: thanks |
| 19:38:13 | GPSFan_away | PCMCIA PC Card Standard Release 2.1 |
| 19:38:23 | GPSFan_away | date july, 1993 |
| 19:43:05 | prpplague | as_: nothing yet.... |
| 19:46:27 | prpplague | hmm, i'm wondering, if your going to use an i/o address in an app, should you map the address, do your access,and then un-map it, or should you map the address at the begning of the app and un-map the exit of the app? |
| 19:47:16 | as_ | This is a long process. |
| 19:47:34 | as_ | It took me several days to find the ISO document for MPEG2. |
| 19:47:47 | prpplague | as_: what looking for a freebie? |
| 19:47:48 | as_ | ISO want to charge money for it. |
| 19:47:52 | as_ | Yes. |
| 19:48:33 | as_ | Does it have an ISO name? |
| 19:48:49 | prpplague | as_: don't think so, or not one i've found |
| 19:49:47 | prpplague | as_: i wonder how good this is - http://www.sycard.com/toc99.html |
| 19:51:01 | as_ | I dont bilieve in paying several hundred pounds to a standards organisation for an electronic copy of a standard that costs nothing for them to produce. |
| 19:51:50 | prpplague | as_: i'd agree with that |
| 19:52:18 | as_ | That looks good, how much is that book? |
| 19:55:50 | prpplague | http://www.amazon.com/exec/obidos/ASIN/0964034220/ref=pd_bxgy_text_1/102-6608671-2348137 |
| 19:56:13 | prpplague | $90 us, guess about 50 punds |
| 19:56:31 | prpplague | s/pund/pounds |
| 19:56:32 | as_ | Thats not bad. |
| 19:56:44 | as_ | Id consider paying that. |
| 19:57:38 | prpplague | did you read the review? |
| 19:59:41 | as_ | Not yet, I have a lot of windows open. |
| 20:02:58 | prpplague | as_: bad reviews |
| 20:03:16 | prpplague | as_: found this page though - http://www.ruske.net/pcmcia.htm |
| 20:04:17 | prpplague | as_: this seems to be the book every is talking about - http://www.amazon.com/exec/obidos/ASIN/0750697474/qid%3D1005512551/ref%3Dsr%5F11%5F0%5F1/102-6608671-2348137 |
| 20:09:44 | as_ | Interesting, and cheeper. |
| 20:09:55 | as_ | By a lot. |
| 20:13:11 | prpplague | hmm seems the pc-card.com group regularly harasses used book dealers who try to sell used copies of the specs |
| 20:13:44 | as_ | Miserable bastards. |
| 20:14:00 | as_ | How much is the spec from there site? |
| 20:15:11 | as_ | If I had access to the spec Id OCR the damn thing. |
| 20:15:22 | prpplague | around $100 IIRC |
| 20:15:52 | as_ | Mmm, not terrible. |
| 20:17:22 | prpplague | i guess when things get to a point where i need it, i'll order it, right now i'm just working on some basic code to access the pcmcia controler |
| 20:19:34 | as_ | Is that an electronic copy, or a printed copy? |
| 20:20:39 | prpplague | printed |
| 20:20:53 | prpplague | although i think it comes with an electronic copy as well |
| 20:22:00 | prpplague | http://www.pc-card.com/bookstore.htm |
| 20:22:13 | prpplague | i was wrong its $300 for non-members |
| 20:22:25 | prpplague | and it does come with an encrypted pdf |
| 20:22:33 | as_ | http://www.rdrop.com/~cary/html/pc_card_faq.html is ok. |
| 20:22:45 | as_ | Oddly enough, printed is better. |
| 20:23:10 | as_ | Electronic copy could be finger printed. |
| 20:23:56 | prpplague | as_: most encrypted pdf files won't read under xpdf |
| 20:24:07 | as_ | xpdf? |
| 20:25:22 | prpplague | x-windows app to view adobe acrobat pdf files |
| 20:25:30 | as_ | Ahh. |
| 20:25:39 | as_ | I dont use nix yet. |
| 20:25:39 | prpplague | hmm looks like this is what i need - http://www.pc-card.com/products/sa-pcm.htm |
| 20:25:47 | prpplague | as_: shhh |
| 20:25:57 | prpplague | as_: don't tell anyone that.... |
| 20:26:29 | as_ | Haha. |
| 20:26:42 | prpplague | has been m$ free for 2 years and 8 months |
| 20:27:13 | as_ | Too much of my hardware wont work under nix. |
| 20:27:54 | prpplague | as_: ??? like what ? |
| 20:28:10 | as_ | Video capture card... |
| 20:29:29 | prpplague | as_: unless its a really oddball unit it should work under linux |
| 20:29:52 | as_ | Its dedicated hardware. |
| 20:30:21 | as_ | I found people trying to develop a nix driver for it, but nothing that works. |
| 20:30:22 | prpplague | ahh |
| 20:30:37 | prpplague | well, make soon then |
| 20:32:15 | as2 | The driver work had been discontinued. |
| 20:32:19 | prpplague | doh |
| 20:32:42 | prpplague | sorry to hear that |
| 20:32:44 | as2 | I only found shadows. Links to the page, and some information in the google cache. |
| 20:33:11 | as2 | Its a shame becuase the driver was going to include features the windows driver doesnt. |
| 20:33:26 | as2 | It primary for that reason I wanted it. |
| 20:33:39 | prpplague | as2: well i just ordered this one - http://www.amazon.com/exec/obidos/ASIN/0201409917/qid=1005514242/sr=8-1/ref=sr_8_5_1/102-6608671-2348137 |
| 20:34:20 | prpplague | as2: didn't get very good reviews, but he uses the cl6722 chipset as examples and thats what i'm working with |
| 20:35:17 | as2 | In the tuxscreen or something else? |
| 20:35:55 | prpplague | as2: this - http://www.inhandelectronics.com/html/elf.html |
| 20:36:51 | as2 | Looking. |
| 20:37:45 | as2 | That looks very cool. |
| 20:38:30 | as2 | Due to my location, my tuxscreen hasnt arrived yet. |
| 20:38:54 | prpplague | as2: where in the uk are you? |
| 20:39:05 | as2 | Midlands. |
| 20:40:34 | Tangent | as2 : I used to live in Telford.. my parents still do |
| 20:41:54 | as2 | Cool. |
| 20:44:24 | prpplague | Tangent: you still alive? |
| 20:47:53 | prpplague | man its dead today! |
| 20:48:09 | prpplague | guess everyone has a life except me and as2 |
| 20:48:38 | prpplague | as2: got a nice pub near where you live? |
| 20:49:34 | GoRK | greetings |
| 20:49:40 | GoRK | i have no life today |
| 20:49:42 | GoRK | i had it yesterday |
| 20:51:15 | GoRK | as2: i wish someone would get the targa cards working in linux. those are awesdome.. built in scsi controllers and the works |
| 20:52:16 | SpaceCoaster | GoRK: how do I play stuff via my shanip? |
| 20:52:50 | GoRK | SpaceCoaster: new kernel or old kernel? |
| 20:53:09 | prpplague | the barbados telco found the problem with our dds circuit - http://www.abcsinc.com/images/56dds.jpg |
| 20:53:10 | SpaceCoaster | GoRK: old kernel, new hardware, one thing at a time. |
| 20:53:31 | GoRK | ok old kernel you have to make a device node |
| 20:53:33 | GoRK | looking... |
| 20:53:50 | GoRK | you are nfs root, right? running debian? |
| 20:54:19 | SpaceCoaster | not really debian, bits of this, bits of that. |
| 20:54:41 | GoRK | well... you should grab madplay and sox |
| 20:54:50 | GoRK | and wget as well |
| 20:56:41 | SpaceCoaster | ok, got madplay, wget, where would I find sox for ARM? |
| 20:57:03 | prpplague | don't you mean sox for feet? |
| 20:57:05 | GoRK | debian testing has it |
| 21:04:12 | prpplague | argh, seven more hours.... |
| 21:06:48 | GoRK | SpaceCoaster: ok mknod /dev/ucb1200-audio c 42 3 |
| 21:06:48 | prpplague | i don't understand why there are so many pda's whit quarter vga displays, 240x320 just isn't big enough for me |
| 21:07:16 | GoRK | SpaceCoaster: symlink that to /dev/dsp |
| 21:07:28 | prpplague | GPSFan: did you check out the pic of the telco pole? |
| 21:11:14 | GPSFan | prpplague: yeah, that was a real snarl. looked like a mix of power & data & telco all chrunched together. |
| 21:12:02 | prpplague | GPSFan: ya pretty nasty, took them 8 hours to re-do that pole to fix our circuit |
| 21:14:13 | GPSFan | prpplague: so it's back on line? |
| 21:15:00 | prpplague | GPSFan: the circuit is testing good now, but we can't switch over untill the store closed for the day, any three hours |
| 21:16:50 | GPSFan | prp, then it's "miller time" not that I would drink miller, but you know what I mean. ;>) |
| 21:17:28 | prpplague | GPSFan: lol yep know what ya mean |
| 21:17:43 | GoRK | SpaceCoaster: you get it working? |
| 21:18:23 | prpplague | GPSFan: although i was hopeing it was something really bad that i'd have to go fix |
| 21:19:03 | GPSFan | prpplague: ;>)) |
| 21:19:56 | prpplague | ohh well maybe next time |
| 21:28:42 | SpaceCoaster | GoRK: sorry, got distracted, couldn't find sox |
| 21:29:13 | GoRK | well you dont really need it except for testing stuff on the new kernel (the new driver is more particular about sample rates) |
| 21:29:49 | SpaceCoaster | GoRK: I suspect that all the rate conversion was taken out of the kernel |
| 21:30:04 | GoRK | SpaceCoaster: exactly. |
| 21:30:42 | SpaceCoaster | I hear that they are going to take crc's out next and we can all checksum our own packets :-) |
| 21:31:43 | GoRK | SpaceCoaster: actually i heard that the kernel was just going to become a way for userspace code to register itself directly with io ports and interrupts |
| 21:32:14 | SpaceCoaster | ok, got wget, got /dev/ucb1200-audio, /dev/dsp, got wget, got madplay |
| 21:32:30 | GoRK | ok just madplay -m your.mp3 |
| 21:32:57 | GoRK | unplug the telephone line from the back of the phone and pick up the handset. you should hear it |
| 21:33:12 | GoRK | if you want to save some processor madplay -m --downsample your.mp3 |
| 21:33:24 | SpaceCoaster | no sound, :-( |
| 21:33:29 | GoRK | the dsp i think resamples down to 11khz anyway |
| 21:33:46 | GoRK | SpaceCoaster: does madplay act like its playing or do you get an error? |
| 21:34:23 | SpaceCoaster | do I need tuxphone, madplay doesn't return and error, it prints the titles etc and then just sits there |
| 21:34:32 | GoRK | yeah it's playing then |
| 21:34:38 | SpaceCoaster | good |
| 21:34:56 | GoRK | tuxphone; no... on the old kernel it just makes it skip :) |
| 21:35:04 | SpaceCoaster | :-) |
| 21:35:41 | GoRK | what did you build your circut w/ ? a breadboard or a pcb? |
| 21:36:16 | SpaceCoaster | on a proto pcb from radioshack |
| 21:36:17 | prpplague | GoRK: i think he said perf board |
| 21:36:52 | GoRK | SpaceCoaster: did you build from teh shanip2 schematic or did you follow a pcb layout? |
| 21:36:56 | prpplague | goes for more coffee |
| 21:37:13 | SpaceCoaster | shanip2 schematic but with a few less GND connections |
| 21:37:26 | GoRK | right you only need signal gnd |
| 21:37:37 | GoRK | hmm ok and you made sure to jumper 3.3v to spk_vcc? |
| 21:38:01 | SpaceCoaster | I didn't do that, is it useful? |
| 21:38:23 | GoRK | hehehe yeah it's necessary for ucb1200 to power its audio output circut :) |
| 21:39:14 | SpaceCoaster | I guess that isn't on the shanip schematic tho' |
| 21:39:34 | prpplague | SpaceCoaster: doh |
| 21:39:43 | GoRK | hmm no it used to be... it showed them jumpered. i just pulled it up and noticed that it was no longer there |
| 21:40:10 | GoRK | hmm ok let me see if i can find a drawing to show you where the pads are |
| 21:40:37 | GoRK | http://www.tuxscreen.net/download/schematics/ucb.jpg |
| 21:40:42 | GoRK | yellow line |
| 21:41:00 | prpplague | SpaceCoaster: you can blame it on GoRK |
| 21:41:11 | GoRK | i didnt make the schematic! gpsfan did! |
| 21:41:19 | GoRK | :) |
| 21:41:31 | prpplague | is being a jerk today |
| 21:41:55 | GoRK | i want macaroni and cheese. i should make some |
| 21:42:10 | prpplague | cat /home/prpplague/personality > /dev/null |
| 21:42:36 | SpaceCoaster | GoRK: how was the toga party? |
| 21:42:47 | GoRK | cat /dev/macaroni /dev/cheese | nc gork stomach |
| 21:43:20 | prpplague | toga party? |
| 21:43:24 | SpaceCoaster | prpplague: yes GoRK is to blame for lots of stuff, audio, speakerphone, etc... |
| 21:44:24 | GoRK | SpaceCoaster: it was fun. we went to walmart and bought fabric. one of my friends got some toy story stuff. another got big smiley faces, i got cow print, my gf got blues clues. the other guy that went with us just wore a brown sheet. i also got some wheat to chew on since i was wearing a cow toga |
| 21:44:25 | prpplague | SpaceCoaster: ya but has he gotten it to say "smeghead" yet? |
| 21:44:28 | SpaceCoaster | so pin 10 --> pin 18 on ucb1200? |
| 21:45:43 | GoRK | SpaceCoaster: right well it looks to be pin 10 -> 17 but yes.. the yellow line indicates where you have to jumper |
| 21:45:54 | prpplague | GoRK: so are you on a college campus or do you normally get invited to toga parties? |
| 21:47:16 | GoRK | prpplague: no i dont go to school anymore but my gf and some other friends still do so i go do that stuff :) |
| 21:47:30 | prpplague | ahh |
| 21:48:59 | prpplague | GoRK: just remember, be very carfull about doing - #mv /tmp/gf /home/wife |
| 21:49:05 | GoRK | SpaceCoaster: im trying to put in the changes between old wheaties.c (that works) and new wheaties.c (that's broken) one by one |
| 21:51:11 | GoRK | prpplague: heh of course. she's still got a few more years before she's done with school anyway ... so it's not really an issue. she'll graduate next fall. then a 6 month internship somewhere other than here, then possibly masters at another school, so :) |
| 21:51:22 | GoRK | we shall see |
| 21:52:00 | prpplague | GoRK: thats cool, sooner or later you'll end up with - #cat /dev/paycheck > /home/wife |
| 21:52:44 | GoRK | haha |
| 21:53:02 | GoRK | wife is more like a fifo though |
| 21:53:22 | GoRK | that gradually increases its buffer size |
| 21:53:26 | prpplague | lol |
| 21:53:28 | prpplague | rofl |
| 21:53:58 | GoRK | eventually you run out of memory and want to ram your rom |
| 21:54:55 | prpplague | or a filesystem, you have to fsck it ever so often, or else you start having problems |
| 21:55:21 | GoRK | the kernel then freaks out and kills your process, which makes the fifo clean up and lie in wait for the next unsuspecting process |
| 21:55:33 | prpplague | lol |
| 21:56:40 | prpplague | you might be a geek if you use unix functions to describe relationships or bodily functions.... |
| 21:58:07 | prpplague | you might be a geek if know all the standard irqs on an x86 board, but can't remember you gf/wife's birthday |
| 21:59:32 | SpaceCoaster | GoRK: got music!! |
| 22:00:25 | prpplague | SpaceCoaster: hope your playing something good.... |
| 22:00:44 | SpaceCoaster | Diamonds on the Soles of Her Shoes |
| 22:02:11 | prpplague | howdy BZFlag |
| 22:02:51 | prpplague | BZFlag: so whens the new addition to the family due? |
| 22:05:00 | GoRK | SpaceCoaster: rock on. |
| 22:05:07 | SpaceCoaster | GoRK: how do I get it out of the speaker? |
| 22:05:20 | GoRK | SpaceCoaster: well... two ways |
| 22:05:29 | GoRK | first you can run tuxphone and hit the speakerphone button |
| 22:05:50 | GoRK | or you can run buzby and set the audio route manually |
| 22:06:02 | GoRK | tuxphone is easier, but you'll see what i mean about the skipping |
| 22:06:55 | GoRK | if you want to test recording you can use netcat... cat /dev/dsp | nc yourpc 5000 |
| 22:06:59 | GoRK | on the tux |
| 22:08:18 | GoRK | and on your pc use nc -l -p 5000 | sox -t .sw -r 8000 - -t ossdsp /dev/dsp |
| 22:09:17 | GoRK | also the new kernel seems to have issues with recording. whenever you try to record, you get weird noise on the speaker lines |
| 22:10:28 | GoRK | basically the ucb1x00 on the new kernel is way messed up :-/ |
| 22:13:38 | boris | Gork: you to make a kernel and jffs2 image for us normal humans? |
| 22:14:00 | SpaceCoaster | playing on the speaker phone, record is a little bit scratched but not too bad. |
| 22:14:23 | boris | +are you |
| 22:14:32 | GoRK | hmm you are using netcat with sox to record? record quality should be pretty good |
| 22:14:42 | GoRK | SpaceCoaster: maybe it is the polarized caps? |
| 22:14:59 | prpplague | cold solder joint? |
| 22:15:11 | SpaceCoaster | GoRK: speaking oldspeak, sounds like a scratched vinyl record! |
| 22:15:34 | SpaceCoaster | GoRK: just a bit clicky, tuxphone effect! |
| 22:15:47 | GoRK | SpaceCoaster: must be something simple in your circut then.. oh yeah or it could be tuxphone too i guess |
| 22:16:39 | GoRK | SpaceCoaster: anyway, good enough to test with eh? |
| 22:17:39 | SpaceCoaster | GoRK: I measure the voltage on the TR OUT + and it was 1.8 when the TuxScreen booted and 0.06 after booting, I connected the + side of the cap to the TR OUT+ line, what do you think? |
| 22:17:58 | GoRK | spacecoater: i dont know. im not an electronics guy :) |
| 22:20:31 | SpaceCoaster | well GPSFan said wire the + side to TR OUT+ to provide a +ve bias, i did, it does and it appears to work, It gives me something to hack with until you get you fancy dancy board sorted. |
| 22:20:45 | GoRK | heh |
| 22:21:03 | GoRK | i need to find a cheap place to get press n peel |
| 22:21:37 | SpaceCoaster | what is cheap? |
| 22:21:50 | GoRK | i dunno. i guess about $1/sheet |
| 22:22:15 | SpaceCoaster | get Tangent to mail you a couple of sheets :-) |
| 22:22:28 | GoRK | heh he's in the UK though. plus i think he ran out |
| 22:22:44 | GoRK | anyway i will just order some from techniks.com . they manufacture the stuff i think |
| 22:23:19 | SpaceCoaster | Ok, better still, buy 30 sheets, take 10 and send the rest to Tangent and charge him what you paid, he will save money and get it quicker! |
| 22:23:46 | SpaceCoaster | GoRK: I lived in the uk too. |
| 22:33:41 | SpaceCoaster | GoRK: does this music play over the phone line? |
| 22:46:54 | Tangent | SpaceCoaster : I pay £15 per 5 sheets from Maplin... I know that's extortion, but I've only ever bought 5 sheets so far |
| 22:47:29 | GoRK | spacecoaster: no |
| 22:47:30 | GoRK | err |
| 22:48:09 | GoRK | Tangent: i just ordered a 20 pack of 8.5x11" for $30 USD |
| 22:48:21 | Tangent | GoRK : That sounds a little more reasonable |
| 22:48:33 | Tangent | GoRK : I thought you were gonna have boards professionally made |
| 22:49:52 | GoRK | Tangent: yes i am but i have to make sure everything lines up and is going to work first before i order a whole ton |
| 22:50:19 | prpplague | Tangent: did you see the telco pic? |
| 22:50:42 | Tangent | GoRK : Nod.. I just happened to get real-lucky when I did my board layout.. The thing turned out to be _exacly_ the right size to fit on a flat bit at the side (approx 2mm clearance) |
| 22:50:47 | Tangent | prpplague : nope |
| 22:51:16 | prpplague | Tangent: remember the bad 56k dds circuit yesterday? well the telco found the problem here - http://www.abcsinc.com/images/56dds.jpg |
| 22:51:54 | Tangent | prpplague : Hmm... not exactly a structured wiring solution |
| 22:52:11 | prpplague | Tangent: thats a big negative |
| 22:52:13 | GoRK | ouch. you'd have to pay me $5000 just to climb up onto that pole |
| 22:52:53 | Tangent | You'd have to convince me that the power was off... then pay me $5000 |
| 22:54:09 | Tangent | Looks like it's in some hot european country... I'm convinced that they're not afraid of electricity in hot european countries |
| 22:54:47 | SpaceCoaster | Ah, the Guru has arrived at last. |
| 22:55:02 | GoRK | it'd be a lot of fun to let the smoke out of that mess |
| 22:55:20 | Tangent | GoRK : And the magic sparks too :) |
| 22:56:03 | SpaceCoaster | Tangent: have you ever seen residential power on poles in the UK? |
| 22:56:18 | Tangent | SpaceCoaster : Yep |
| 22:56:29 | Tangent | SpaceCoaster : Usually in pairs, with a transformer mounted at the top |
| 22:57:12 | SpaceCoaster | Tangent: yeah, that's what it's like here, In florida my place has a massive bucket up a pole to power the air conditioning etc. |
| 22:57:52 | Tangent | SpaceCoaster : It's the only way to ship your power around... lots of volts, so you don't need the current |
| 22:58:24 | Tangent | is always impressed by the clever trick the power companies do in winter |
| 22:58:29 | SpaceCoaster | Tangent: and telephone lines and cable tv and everything else, I waiting to see a place which has gas pipes strung between poles. |
| 22:59:10 | prpplague | Tangent: thats in barbados |
| 22:59:10 | Tangent | SpaceCoaster : In the UK they have different poles for the differnet services.. but you know that.. you're in the UK |
| 22:59:24 | Tangent | prpplague : Yeah.. looked somewhere hot |
| 22:59:30 | GoRK | SpaceCoaster: a lot of oil and gas pipeline is run above ground. some is heated, like the alaskan pipeline :) |
| 23:00:26 | SpaceCoaster | Tangent: no I'm in New Hampshire, i moved from Edinburgh last year. |
| 23:00:40 | Tangent | SpaceCoaster : Ah.. I see |
| 23:01:22 | SpaceCoaster | It was just the photo looked like lots of stuff I've seen here and in Florida, looks weird/dangerous to me. |
| 23:02:20 | Tangent | spots the /. article about openprojects.net's recent upgrade |
| 23:09:33 | Guru | prpplague: December 18th, it's a boy (or it should be ;-) |
| 23:14:08 | prpplague | BZFlag: cool |
| 23:29:42 | prpplague | whoo, circuit is UP |
| 23:47:39 | EGg0 | BZFlag: You around? |
