|---|---|---|
| kristianpaul | wb | 09:59 |
| nebajoth | how are you | 09:59 |
| nebajoth | kristianpaul: what is your current nanonote project, if I may ask? | 10:02 |
| kristianpaul | nebajoth: oh sure | 10:04 |
| kristianpaul | i'm working on GPS for the nanonote | 10:04 |
| nebajoth | ah yes | 10:04 |
| nebajoth | have you been participating in that mailing list thread then? | 10:04 |
| kristianpaul | yes | 10:04 |
| nebajoth | I've been skimming it | 10:04 |
| nebajoth | interested, but not enough to read all of it | 10:05 |
| kristianpaul | i see | 10:05 |
| nebajoth | I saw you had some success | 10:05 |
| kristianpaul | well that happens | 10:05 |
| kristianpaul | yup some basic so far | 10:05 |
| nebajoth | but I don't know enough to know how difficult the actual mod was | 10:05 |
| kristianpaul | but gps proven to work | 10:05 |
| nebajoth | for exampkle | 10:05 |
| nebajoth | you soldered to the serial port points beneath the battery case somehow? | 10:05 |
| nebajoth | truthfully, this is a matter that DOES interest me | 10:06 |
| nebajoth | I just had it further down my list | 10:06 |
| nebajoth | personally, I'm struggling with just getting the UI "right" | 10:06 |
| kristianpaul | well i not use those | 10:06 |
| kristianpaul | there are some labeled TP4/5 | 10:06 |
| kristianpaul | wich are the same uart | 10:07 |
| nebajoth | located where? | 10:07 |
| nebajoth | directly on the chipset? | 10:07 |
| kristianpaul | near to the SoC | 10:07 |
| nebajoth | sorry, I've only opened mine once | 10:07 |
| nebajoth | I'm a software d00d | 10:07 |
| Action: nebajoth is pulling up a photo of NN internals | 10:08 | |
| kristianpaul | nebajoth: http://en.qi-hardware.com/wiki/File:IMG_0082.JPG | 10:09 |
| nebajoth | ah yes, they're all over the board | 10:09 |
| nebajoth | did you follow tuxbrain's arduino mod? | 10:10 |
| kristianpaul | no | 10:10 |
| kristianpaul | me no like it | 10:10 |
| nebajoth | you looked at the ben's schematics? | 10:10 |
| nebajoth | determined the uart points | 10:10 |
| nebajoth | what's on the other end of those wires? | 10:11 |
| kristianpaul | note at all, Carlos did and tell us on the list | 10:11 |
| nebajoth | haha | 10:11 |
| nebajoth | fair enough | 10:11 |
| kristianpaul | uart | 10:11 |
| nebajoth | open source hardware is awesome | 10:11 |
| kristianpaul | same as under battery i think | 10:11 |
| kristianpaul | yup | 10:11 |
| nebajoth | I've determined that you can break out the ones under the battery easily enough | 10:11 |
| nebajoth | with very narrow gauge wire | 10:11 |
| nebajoth | the battery still rests neatly, and provides electrical charge to the unit | 10:12 |
| nebajoth | with 32" wire | 10:12 |
| kristianpaul | yes i'm looking for playstaion bus right now, i was told that is really tiny | 10:12 |
| nebajoth | what kind of connector? | 10:12 |
| nebajoth | I see | 10:12 |
| kristianpaul | where? | 10:12 |
| nebajoth | on the UART end | 10:12 |
| nebajoth | I can see the end soldered to the board | 10:13 |
| nebajoth | what do you use on the other end to connect to the gps unit? | 10:13 |
| kristianpaul | nahjust a mess of wires | 10:13 |
| nebajoth | haha | 10:13 |
| nebajoth | NEEDS MORE PLUG AND PLAY | 10:13 |
| kristianpaul | sure | 10:13 |
| nebajoth | excuse me | 10:13 |
| kristianpaul | i need a smaller gps to try first | 10:13 |
| nebajoth | I realize it is internet protocol not to use caps | 10:13 |
| nebajoth | but my other channel is a gaming clan channel | 10:14 |
| kristianpaul | oh | 10:14 |
| nebajoth | and sometimes I slip into ALL OUT BROADCAST MODE | 10:14 |
| kristianpaul | :) | 10:14 |
| nebajoth | its not shouting, at least to my head | 10:14 |
| nebajoth | its like | 10:14 |
| nebajoth | computer voice | 10:14 |
| kristianpaul | i think the next move is get a small and cheap gps to attach | 10:14 |
| nebajoth | NEEDS MORE BATTERIES | 10:14 |
| kristianpaul | i'll be fine if is small enought to fit inside | 10:14 |
| nebajoth | I assume yours is non-small and non-cheap. | 10:15 |
| nebajoth | aren't there SD GPS units? | 10:15 |
| kristianpaul | yeah? | 10:15 |
| kristianpaul | dont know | 10:15 |
| kristianpaul | mine is http://en.qi-hardware.com/wiki/File:IMG_1581.JPG | 10:15 |
| nebajoth | rofl | 10:15 |
| nebajoth | http://www.pocketgpsworld.com/reviews/globalsat-sdio-gps/globalsat-sd501-booster.jpg | 10:15 |
| kristianpaul | is not just gps board so is big | 10:15 |
| kristianpaul | oh | 10:15 |
| nebajoth | too big | 10:16 |
| nebajoth | to fit inside | 10:16 |
| kristianpaul | yeah | 10:16 |
| nebajoth | too big to fit into microsd | 10:16 |
| nebajoth | but funny looking anyway | 10:16 |
| nebajoth | omfg | 10:17 |
| nebajoth | guess what company you get to | 10:17 |
| nebajoth | first google result | 10:17 |
| nebajoth | "gps sd card receiver" | 10:17 |
| nebajoth | effing spectec | 10:17 |
| nebajoth | with their effing wifi priced more than vehicle | 10:17 |
| kristianpaul | heh | 10:17 |
| kristianpaul | but you know what is not bad idea use sdio maybe custom boars to attach gps | 10:18 |
| nebajoth | oh snap | 10:18 |
| nebajoth | what about | 10:18 |
| kristianpaul | ah but we need jlime runnning from flash to do that btw rafa ;) | 10:18 |
| nebajoth | pcmcia | 10:19 |
| nebajoth | too big? | 10:19 |
| nebajoth | even if you take it apart? | 10:19 |
| nebajoth | or compact flash | 10:19 |
| kristianpaul | big indeed | 10:19 |
| kristianpaul | bbl | 10:22 |
| nebajoth | it'd be so much easier to just connect serial to bluetooth | 10:25 |
| kristianpaul | nebajoth: not a bad idea | 13:02 |
| kristianpaul | not using bluetook but maybe hoperf modules ! | 13:03 |
| kristianpaul | wich i have some here | 13:03 |
| kristianpaul | ahh but those are SPI, i still requirin other MCU.. | 13:04 |
| kristianpaul | at least implement SPI by software | 13:06 |
| kristianpaul | but it require 6 pins | 13:07 |
| kristianpaul | not sure if there are gpio avaliable upto that number.. | 13:07 |
| emeb | kristianpaul: I was looking at the ben schematics and it appears there are about 5-6 pins free | 13:21 |
| emeb | some may actually be spi pins too... | 13:21 |
| emeb | (not just bitbang gpio) | 13:22 |
| kristianpaul | oh | 13:29 |
| kristianpaul | emeb: wich pins? | 13:31 |
| emeb | kristianpaul: don't remember now. That was a few weeks back. | 13:32 |
| emeb | IIRC though there is a list on the wiki | 13:32 |
| kristianpaul | yes | 13:32 |
| kristianpaul | i saw it before, but no confirmed wichones are avalible for wiring | 13:33 |
| emeb | yep - some are hard to get to. | 13:33 |
| Ornotermes | kristianpaul: why not share SPI with the sd slot? | 13:34 |
| emeb | could require serious kernel code changes | 13:34 |
| kristianpaul | hmm yes | 13:35 |
| Ornotermes | probably, but i woult think it would be a good thing to have another (internal) spi by default | 13:35 |
| kristianpaul | yes | 13:35 |
| Ornotermes | for both network and memory card | 13:35 |
| Ornotermes | or what ever that uses spi :) | 13:36 |
| kristianpaul | hoperf :) | 13:36 |
| kristianpaul | is small i think it will fit, just need to be wired and sofware supported | 13:36 |
| Ornotermes | how cheap is hoperf by the way? | 13:38 |
| kristianpaul | 2.5usd per unit if oyu buy samples in china | 13:39 |
| kristianpaul | i recommend you buy more that 20 to make shipping conpensate the costs | 13:40 |
| kristianpaul | at least you are in china ;) | 13:40 |
| Ornotermes | quite good, there is a company selleing uart radio modems for about 15USD | 13:42 |
| Ornotermes | but they need 5V | 13:42 |
| kristianpaul | ouch | 13:42 |
| Ornotermes | but slip would be neat | 13:42 |
| Ornotermes | http://translate.google.com/translate?js=y&prev=_t&hl=en&ie=UTF-8&layout=1&eotf=1&u=http%3A%2F%2Fswechtrading.se%2Fzencart%2Findex.php%3Fmain_page%3Dproduct_info%26cPath%3D52%26products_id%3D614&sl=sv&tl=en | 13:43 |
| Ornotermes | there is uart wifi modules too btw, but they are rather big and expencive | 13:47 |
| kristianpaul | :( | 13:48 |
| Ornotermes | http://lairdtech.thomasnet.com/item/wlan-radio-modules/s-802-11b-g-slip-wireless-lan-module-device-server/wismc03bi? | 13:53 |
| Ornotermes | i think those would cost around 100-150USD | 13:54 |
| wpwrak | Ornotermes: you could just add some cheap microcontroller to do a UART to SPI conversion | 14:03 |
| Ornotermes | sure | 14:04 |
| kristianpaul | wpwrak: yes i tought that too, but it must be relly small | 14:07 |
| kristianpaul | may be a atmel tiny or soemthing | 14:07 |
| wpwrak | ooh ! i see on http://www.openmobilefree.net/?p=504 that xiangfu has managed to separate the LCM. whee ! | 14:07 |
| kristianpaul | yes is quite simple | 14:07 |
| kristianpaul | i think is harder the other case | 14:08 |
| wpwrak | kristianpaul: (uart to spi) there should be plenty of chips in a 4 mm qfn that can do this | 14:08 |
| kristianpaul | yeah just need searchi as always | 14:09 |
| wpwrak | (lcm) ah, how to you release the hinge ? do you have to open the display case for this ? | 14:11 |
| Ornotermes | many avr tiny have USI(Universal Serial Interface), so they can't use uart and spi at the same time | 14:13 |
| kristianpaul | :/ | 14:17 |
| kristianpaul | wpwrak: yes | 14:17 |
| wpwrak | Ornotermes: you can do the SPI just by bit-banging. if the MCU isn't doing anything else but copying between UART and SPI, it has plenty of time for that. | 14:22 |
| wpwrak | kristianpaul: aah ! so that's the secret ! thanks ! | 14:23 |
| Action: wpwrak grabs a knife | 14:23 | |
| kristianpaul | :D | 14:25 |
| kristianpaul | wpwrak: there are some screws but you need the knife first, be carefull | 14:26 |
| Ornotermes | wpwrak: ofc :) i forget about bitbanging some times :P | 14:26 |
| Action: kristianpaul reads about bitbanging | 14:27 | |
| emeb | there's a bitbang SPI driver in kernel already - just tell it what pins to use and what backend to connect to | 14:28 |
| Action: emeb has used spi on beagleboard & mini2440 | 14:28 | |
| kristianpaul | oh | 14:31 |
| kristianpaul | emeb: remenber the module name? | 14:31 |
| Ornotermes | spi_gpio if i remember it right | 14:32 |
| kristianpaul | man linux is so big and full of features :) | 14:32 |
| emeb | deep and wide. | 14:33 |
| Ornotermes | btw, im trying to write a tetris game for ben in python+pygame | 14:45 |
| wpwrak | emeb: very good point. of course, that almost makes things too easy :) | 16:38 |
| Action: emeb hasn't used the bitbang driver for anything except the /cs line | 16:42 | |
| emeb | and I use the spidev backend (frontend?) | 16:43 |
| emeb | works a treat | 16:43 |
| wpwrak | emeb: i played a bit with it for sdio. before finding the sdio interface bugs in the silicon that affected only one or two very specific revisions of the samsung 2442. | 16:45 |
| wpwrak | well, about a month or two before finding these. it's not the kind of thing you look for in the first place ... | 16:45 |
| Action: emeb hates undocumented silicon features | 16:47 | |
| emeb | I wonder if there's something wrong with SPI DMA on the s3c2440 - the spi driver doesn't use DMA and it's slooooow | 16:48 |
| wpwrak | emeb: there were various dma issues in the 244x series. not sure if this is one, though. some of the drivers are just a bit under-developed. | 17:02 |
| emeb | wpwrak: makes sense. | 17:06 |
| larsc | in the latest iteration of the driver there is dma support | 17:26 |
| emeb | larsc: what rev is that in? | 18:04 |
| larsc | HEAD ;) | 18:06 |
| emeb | guess I asked for that :P | 18:07 |
| larsc | i don't know when it got in but 2.6.34 had support for it iirc | 18:07 |
| emeb | ok - .34 is a good start | 18:07 |
| emeb | thanks | 18:08 |
| emeb | gotta see if I can backport that to the .32 kernel that comes with the mini2440... | 18:10 |
| emeb | .34 has FIQ-based pseudo DMA as a config option, not real DMA | 18:15 |
| gbraad | wolfspraul: nice indication of #slowfi in action http://en.wikipedia.org/wiki/Team_OneBeep | 22:54 |
| wolfspraul | gbraad: hey | 22:54 |
| wolfspraul | tuxbrain: you there? | 22:55 |
| wolfspraul | must the middle of the night there, no? | 22:55 |
| gbraad | in europe ? yes, 5am | 22:55 |
| wolfspraul | gbraad: OneBeep is cool, nice link - thanks | 22:56 |
| wolfspraul | how are things on your end? | 22:56 |
| wolfspraul | where is Fedora on NanoNote? t-shirts? etc. :-) | 22:56 |
| gbraad | standard radio, also pushed it to jon. | 22:56 |
| gbraad | fedora on mips is at F13, on nanonote stalled now. still have issues with the build infra | 22:57 |
| wolfspraul | Yanjun Luo is pretty cool on the cable, but we need to teach him the slow culture a bit :-) | 22:57 |
| wolfspraul | no email attachments, check it in in a nice repo, make sure author and license is all attributed correctly, and so on | 22:57 |
| gbraad | have not been able to do the shirts due to budget of fedora | 22:57 |
| gbraad | exactly. I told him to use a repo, but not done yet. | 22:58 |
| wolfspraul | but seems to be a really cool guy | 22:58 |
| wolfspraul | he can use the qi projects server | 22:58 |
| gbraad | he is... too bad for the arm project he does ;-) | 22:58 |
| gbraad | i had the same idea. but open source is still young in China | 22:58 |
| wolfspraul | I am planning to get some scripts going on that server that can auto-generate PDF schematics etc. for kicad files... | 22:59 |
| gbraad | (and misunderstood) | 22:59 |
| wolfspraul | (but not there yet) | 22:59 |
| wolfspraul | misunderstood? you mean free software? | 22:59 |
| wolfspraul | let's meet with Yanjun asap | 22:59 |
| gbraad | had some discussion with jon about the OSHW | 22:59 |
| wolfspraul | I want to give him some higher-level objectives and see whether he can take it. | 23:00 |
| gbraad | open source in general is an issue in China. not completely understood. but already got in touch with some key people. have been very busy with this. | 23:00 |
| gbraad | seems like a good idea | 23:00 |
| wolfspraul | he - good luck | 23:00 |
| wolfspraul | don't try to educate china, my advice | 23:01 |
| wolfspraul | waste of time - oldest culture (i.e. slowest/never in changing) - there's a reason... | 23:01 |
| gbraad | i don't educate. but learn and see how we can adopt | 23:01 |
| wolfspraul | we can only use them, and offer our true advice and help if someone wants to really understand the free software culture | 23:01 |
| wolfspraul | that's gonna be a 1 in a million type of person | 23:02 |
| gbraad | if you meet the right people, they are listening... and i did meet some of them. ;-) | 23:02 |
| wolfspraul | sure | 23:02 |
| gbraad | wolfspraul: what is your vision on the OSHW? | 23:05 |
| gbraad | seems milkymist endorsed it | 23:05 |
| wolfspraul | vision? | 23:05 |
| gbraad | http://freedomdefined.org/OSHW | 23:05 |
| gbraad | opinion | 23:05 |
| gbraad | in my sense it is weak! | 23:06 |
| wolfspraul | I'm a believer in the old IETF approach - implementation first, then standardization | 23:06 |
| wolfspraul | so that's what I do with copyleft hardware | 23:06 |
| wolfspraul | does that answer your question? | 23:06 |
| wolfspraul | I think the GPL v3 is a great license | 23:06 |
| wolfspraul | so is cc-by-sa | 23:06 |
| wolfspraul | after that we have many details to learn and find out about in reality, when doing copyleft hardware, as we do | 23:07 |
| wolfspraul | sorry gotta run... | 23:08 |
| gbraad | no prob | 23:08 |
| wolfspraul | bbl | 23:08 |
| gbraad | slow connection, so hard to talk | 23:08 |
| wolfspraul | oshw v0.3 doc doesn't give me much/anything right now | 23:08 |
| wolfspraul | but nice someone works, wish them good luck maybe they can come out with a strong and interesting document one day... | 23:08 |
| gbraad | i hope so, as this is weak | 23:09 |
| gbraad | see ya | 23:09 |
