2010-07-18 09:56 <nebajoth> o/
2010-07-18 09:59 <kristianpaul> wb
2010-07-18 09:59 <nebajoth> how are you
2010-07-18 10:02 <nebajoth> kristianpaul: what is your current nanonote project, if I may ask?
2010-07-18 10:04 <kristianpaul> nebajoth: oh sure
2010-07-18 10:04 <kristianpaul> i'm working on GPS for the nanonote
2010-07-18 10:04 <nebajoth> ah yes
2010-07-18 10:04 <nebajoth> have you been participating in that mailing list thread then?
2010-07-18 10:04 <kristianpaul> yes
2010-07-18 10:04 <nebajoth> I've been skimming it
2010-07-18 10:05 <nebajoth> interested, but not enough to read all of it
2010-07-18 10:05 <kristianpaul> i see
2010-07-18 10:05 <nebajoth> I saw you had some success
2010-07-18 10:05 <kristianpaul> well that happens
2010-07-18 10:05 <kristianpaul> yup some basic so far
2010-07-18 10:05 <nebajoth> but I don't know enough to know how difficult the actual mod was
2010-07-18 10:05 <kristianpaul> but gps proven to work
2010-07-18 10:05 <nebajoth> for exampkle
2010-07-18 10:05 <nebajoth> you soldered to the serial port points beneath the battery case somehow?
2010-07-18 10:06 <nebajoth> truthfully, this is a matter that DOES interest me
2010-07-18 10:06 <nebajoth> I just had it further down my list
2010-07-18 10:06 <nebajoth> personally, I'm struggling with just getting the UI "right"
2010-07-18 10:06 <kristianpaul> well i not use those
2010-07-18 10:06 <kristianpaul> there are some labeled TP4/5
2010-07-18 10:07 <kristianpaul> wich are the same uart
2010-07-18 10:07 <nebajoth> located where?
2010-07-18 10:07 <nebajoth> directly on the chipset?
2010-07-18 10:07 <kristianpaul> near to the SoC
2010-07-18 10:07 <nebajoth> sorry, I've only opened mine once
2010-07-18 10:07 <nebajoth> I'm a software d00d
2010-07-18 10:08 <nebajoth> is pulling up a photo of NN internals
2010-07-18 10:09 <kristianpaul> nebajoth: http://en.qi-hardware.com/wiki/File:IMG_0082.JPG
2010-07-18 10:09 <nebajoth> ah yes, they're all over the board
2010-07-18 10:10 <nebajoth> did you follow tuxbrain's arduino mod?
2010-07-18 10:10 <kristianpaul> no
2010-07-18 10:10 <kristianpaul> me no like it
2010-07-18 10:10 <nebajoth> you looked at the ben's schematics?
2010-07-18 10:10 <nebajoth> determined the uart points
2010-07-18 10:11 <nebajoth> what's on the other end of those wires?
2010-07-18 10:11 <kristianpaul> note at all, Carlos did and tell us on the list
2010-07-18 10:11 <nebajoth> haha
2010-07-18 10:11 <nebajoth> fair enough
2010-07-18 10:11 <kristianpaul> uart
2010-07-18 10:11 <nebajoth> open source hardware is awesome
2010-07-18 10:11 <kristianpaul> same as under battery i think
2010-07-18 10:11 <kristianpaul> yup
2010-07-18 10:11 <nebajoth> I've determined that you can break out the ones under the battery easily enough
2010-07-18 10:11 <nebajoth> with very narrow gauge wire
2010-07-18 10:12 <nebajoth> the battery still rests neatly, and provides electrical charge to the unit
2010-07-18 10:12 <nebajoth> with 32" wire
2010-07-18 10:12 <kristianpaul> yes i'm looking for playstaion bus right now, i was told that is really tiny
2010-07-18 10:12 <nebajoth> what kind of connector?
2010-07-18 10:12 <nebajoth> I see
2010-07-18 10:12 <kristianpaul> where?
2010-07-18 10:12 <nebajoth> on the UART end
2010-07-18 10:13 <nebajoth> I can see the end soldered to the board
2010-07-18 10:13 <nebajoth> what do you use on the other end to connect to the gps unit?
2010-07-18 10:13 <kristianpaul> nahjust a mess of wires
2010-07-18 10:13 <nebajoth> haha
2010-07-18 10:13 <nebajoth> NEEDS MORE PLUG AND PLAY
2010-07-18 10:13 <kristianpaul> sure
2010-07-18 10:13 <nebajoth> excuse me
2010-07-18 10:13 <kristianpaul> i need a smaller gps to try first
2010-07-18 10:13 <nebajoth> I realize it is internet protocol not to use caps
2010-07-18 10:14 <nebajoth> but my other channel is a gaming clan channel
2010-07-18 10:14 <kristianpaul> oh
2010-07-18 10:14 <nebajoth> and sometimes I slip into ALL OUT BROADCAST MODE
2010-07-18 10:14 <kristianpaul> :)
2010-07-18 10:14 <nebajoth> its not shouting, at least to my head
2010-07-18 10:14 <nebajoth> its like
2010-07-18 10:14 <nebajoth> computer voice
2010-07-18 10:14 <kristianpaul> i think the next move is get a small and cheap gps to attach
2010-07-18 10:14 <nebajoth> NEEDS MORE BATTERIES
2010-07-18 10:14 <kristianpaul> i'll be fine if is small enought to fit inside
2010-07-18 10:15 <nebajoth> I assume yours is non-small and non-cheap.
2010-07-18 10:15 <nebajoth> aren't there SD GPS units?
2010-07-18 10:15 <kristianpaul> yeah?
2010-07-18 10:15 <kristianpaul> dont know
2010-07-18 10:15 <kristianpaul> mine is  http://en.qi-hardware.com/wiki/File:IMG_1581.JPG
2010-07-18 10:15 <nebajoth> rofl
2010-07-18 10:15 <nebajoth> http://www.pocketgpsworld.com/reviews/globalsat-sdio-gps/globalsat-sd501-booster.jpg
2010-07-18 10:15 <kristianpaul> is not just gps board so is big
2010-07-18 10:15 <kristianpaul> oh
2010-07-18 10:16 <nebajoth> too big
2010-07-18 10:16 <nebajoth> to fit inside
2010-07-18 10:16 <kristianpaul> yeah
2010-07-18 10:16 <nebajoth> too big to fit into microsd
2010-07-18 10:16 <nebajoth> but funny looking anyway
2010-07-18 10:17 <nebajoth> omfg
2010-07-18 10:17 <nebajoth> guess what company you get to
2010-07-18 10:17 <nebajoth> first google result
2010-07-18 10:17 <nebajoth> "gps sd card receiver"
2010-07-18 10:17 <nebajoth> effing spectec
2010-07-18 10:17 <nebajoth> with their effing wifi priced more than vehicle
2010-07-18 10:17 <kristianpaul> heh
2010-07-18 10:18 <kristianpaul> but you know what is not bad idea use sdio maybe custom boars to attach gps
2010-07-18 10:18 <nebajoth> oh snap
2010-07-18 10:18 <nebajoth> what about
2010-07-18 10:18 <kristianpaul> ah but we need jlime runnning from flash to do that btw rafa ;)
2010-07-18 10:19 <nebajoth> pcmcia
2010-07-18 10:19 <nebajoth> too big?
2010-07-18 10:19 <nebajoth> even if you take it apart?
2010-07-18 10:19 <nebajoth> or compact flash
2010-07-18 10:19 <kristianpaul> big indeed
2010-07-18 10:22 <kristianpaul> bbl
2010-07-18 10:25 <nebajoth> it'd be so much easier to just connect serial to bluetooth
2010-07-18 13:02 <kristianpaul> nebajoth: not a bad idea
2010-07-18 13:03 <kristianpaul> not using bluetook but maybe hoperf modules !
2010-07-18 13:03 <kristianpaul> wich i have some here
2010-07-18 13:04 <kristianpaul> ahh but those are SPI, i still requirin other MCU..
2010-07-18 13:06 <kristianpaul> at least implement SPI by software
2010-07-18 13:07 <kristianpaul> but it require 6 pins
2010-07-18 13:07 <kristianpaul> not sure if there are gpio avaliable upto that number..
2010-07-18 13:21 <emeb> kristianpaul: I was looking at the ben schematics and it appears there are about 5-6 pins free
2010-07-18 13:21 <emeb> some may actually be spi pins too...
2010-07-18 13:22 <emeb> (not just bitbang gpio)
2010-07-18 13:29 <kristianpaul> oh
2010-07-18 13:31 <kristianpaul> emeb: wich pins?
2010-07-18 13:32 <emeb> kristianpaul: don't remember now. That was a few weeks back.
2010-07-18 13:32 <emeb> IIRC though there is a list on the wiki
2010-07-18 13:32 <kristianpaul> yes
2010-07-18 13:33 <kristianpaul> i saw it before, but no confirmed wichones are avalible for wiring
2010-07-18 13:33 <emeb> yep - some are hard to get to.
2010-07-18 13:34 <Ornotermes> kristianpaul: why not share SPI with the sd slot?
2010-07-18 13:34 <emeb> could require serious kernel code changes
2010-07-18 13:35 <kristianpaul> hmm yes
2010-07-18 13:35 <Ornotermes> probably, but i woult think it would be a good thing to have another (internal) spi by default
2010-07-18 13:35 <kristianpaul> yes
2010-07-18 13:35 <Ornotermes> for both network and memory card
2010-07-18 13:36 <Ornotermes> or what ever that uses spi :)
2010-07-18 13:36 <kristianpaul> hoperf :)
2010-07-18 13:36 <kristianpaul> is small i think it will fit, just need to be wired and sofware supported
2010-07-18 13:38 <Ornotermes> how cheap is hoperf by the way?
2010-07-18 13:39 <kristianpaul> 2.5usd per unit if oyu buy samples in china
2010-07-18 13:40 <kristianpaul> i recommend you buy more that 20 to make shipping conpensate the costs
2010-07-18 13:40 <kristianpaul> at least you are in china ;)
2010-07-18 13:42 <Ornotermes> quite good, there is a company selleing uart radio modems for about 15USD
2010-07-18 13:42 <Ornotermes> but they need 5V
2010-07-18 13:42 <kristianpaul> ouch
2010-07-18 13:42 <Ornotermes> but slip would be neat
2010-07-18 13:43 <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
2010-07-18 13:47 <Ornotermes> there is uart wifi modules too btw, but they are rather big and expencive
2010-07-18 13:48 <kristianpaul> :(
2010-07-18 13:53 <Ornotermes> http://lairdtech.thomasnet.com/item/wlan-radio-modules/s-802-11b-g-slip-wireless-lan-module-device-server/wismc03bi?
2010-07-18 13:54 <Ornotermes> i think those would cost around 100-150USD
2010-07-18 14:03 <wpwrak> Ornotermes: you could just add some cheap microcontroller to do a UART to SPI conversion
2010-07-18 14:04 <Ornotermes> sure
2010-07-18 14:07 <kristianpaul> wpwrak: yes i tought that too, but it must be relly small
2010-07-18 14:07 <kristianpaul> may be a atmel tiny or soemthing
2010-07-18 14:07 <wpwrak> ooh ! i see on http://www.openmobilefree.net/?p=504 that xiangfu has managed to separate the LCM. whee !
2010-07-18 14:07 <kristianpaul> yes is quite simple
2010-07-18 14:08 <kristianpaul> i think is harder the other case
2010-07-18 14:08 <wpwrak> kristianpaul: (uart to spi) there should be plenty of chips in a 4 mm qfn that can do this
2010-07-18 14:09 <kristianpaul> yeah just need searchi as always
2010-07-18 14:11 <wpwrak> (lcm) ah, how to you release the hinge ? do you have to open the display case for this ?
2010-07-18 14:13 <Ornotermes> many avr tiny have USI(Universal Serial Interface), so they can't use uart and spi at the same time
2010-07-18 14:17 <kristianpaul> :/
2010-07-18 14:17 <kristianpaul> wpwrak: yes
2010-07-18 14:22 <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.
2010-07-18 14:23 <wpwrak> kristianpaul: aah ! so that's the secret ! thanks !
2010-07-18 14:23 <wpwrak> grabs a knife
2010-07-18 14:25 <kristianpaul> :D
2010-07-18 14:26 <kristianpaul> wpwrak: there are some screws but you need the knife first, be carefull
2010-07-18 14:26 <Ornotermes> wpwrak: ofc :) i forget about bitbanging some times :P
2010-07-18 14:27 <kristianpaul> reads about bitbanging
2010-07-18 14:28 <emeb> there's a bitbang SPI driver in kernel already - just tell it what pins to use and what backend to connect to
2010-07-18 14:28 <emeb> has used spi on beagleboard & mini2440
2010-07-18 14:31 <kristianpaul> oh
2010-07-18 14:31 <kristianpaul> emeb: remenber the module name?
2010-07-18 14:32 <Ornotermes> spi_gpio if i remember it right
2010-07-18 14:32 <kristianpaul> man linux is so big and full of features :)
2010-07-18 14:33 <emeb> deep and wide.
2010-07-18 14:45 <Ornotermes> btw, im trying to write a tetris game for ben in python+pygame
2010-07-18 16:38 <wpwrak> emeb: very good point. of course, that almost makes things too easy :)
2010-07-18 16:42 <emeb> hasn't used the bitbang driver for anything except the /cs line
2010-07-18 16:43 <emeb> and I use the spidev backend (frontend?)
2010-07-18 16:43 <emeb> works a treat
2010-07-18 16:45 <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.
2010-07-18 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 ...
2010-07-18 16:47 <emeb> hates undocumented silicon features
2010-07-18 16:48 <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
2010-07-18 17:02 <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.
2010-07-18 17:06 <emeb> wpwrak: makes sense.
2010-07-18 17:26 <larsc> in the latest iteration of the driver there is dma support
2010-07-18 18:04 <emeb> larsc: what rev is that in?
2010-07-18 18:06 <larsc> HEAD ;)
2010-07-18 18:07 <emeb> guess I asked for that :P
2010-07-18 18:07 <larsc> i don't know when it got in but 2.6.34 had support for it iirc
2010-07-18 18:07 <emeb> ok - .34 is a good start
2010-07-18 18:08 <emeb> thanks
2010-07-18 18:10 <emeb> gotta see if I can backport that to the .32 kernel that comes with the mini2440...
2010-07-18 18:15 <emeb> .34 has FIQ-based pseudo DMA as a config option, not real DMA
2010-07-18 22:54 <gbraad> wolfspraul: nice indication of #slowfi in action http://en.wikipedia.org/wiki/Team_OneBeep
2010-07-18 22:54 <wolfspraul> gbraad: hey
2010-07-18 22:55 <wolfspraul> tuxbrain: you there?
2010-07-18 22:55 <wolfspraul> must the middle of the night there, no?
2010-07-18 22:55 <gbraad> in europe ? yes, 5am
2010-07-18 22:56 <wolfspraul> gbraad: OneBeep is cool, nice link - thanks
2010-07-18 22:56 <wolfspraul> how are things on your end?
2010-07-18 22:56 <wolfspraul> where is Fedora on NanoNote? t-shirts? etc. :-)
2010-07-18 22:56 <gbraad> standard radio, also pushed it to jon.
2010-07-18 22:57 <gbraad> fedora on mips is at F13, on nanonote stalled now. still have issues with the build infra
2010-07-18 22:57 <wolfspraul> Yanjun Luo is pretty cool on the cable, but we need to teach him the slow culture a bit :-)
2010-07-18 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
2010-07-18 22:57 <gbraad> have not been able to do the shirts due to budget of fedora
2010-07-18 22:58 <gbraad> exactly. I told him to use a repo, but not done yet.
2010-07-18 22:58 <wolfspraul> but seems to be a really cool guy
2010-07-18 22:58 <wolfspraul> he can use the qi projects server
2010-07-18 22:58 <gbraad> he is... too bad for the arm project he does ;-)
2010-07-18 22:58 <gbraad> i had the same idea. but open source is still young in China
2010-07-18 22:59 <wolfspraul> I am planning to get some scripts going on that server that can auto-generate PDF schematics etc. for kicad files...
2010-07-18 22:59 <gbraad> (and misunderstood)
2010-07-18 22:59 <wolfspraul> (but not there yet)
2010-07-18 22:59 <wolfspraul> misunderstood? you mean free software?
2010-07-18 22:59 <wolfspraul> let's meet with Yanjun asap
2010-07-18 22:59 <gbraad> had some discussion with jon about the OSHW
2010-07-18 23:00 <wolfspraul> I want to give him some higher-level objectives and see whether he can take it.
2010-07-18 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.
2010-07-18 23:00 <gbraad> seems like a good idea
2010-07-18 23:00 <wolfspraul> he - good luck
2010-07-18 23:01 <wolfspraul> don't try to educate china, my advice
2010-07-18 23:01 <wolfspraul> waste of time - oldest culture (i.e. slowest/never in changing) - there's a reason...
2010-07-18 23:01 <gbraad> i don't educate. but learn and see how we can adopt
2010-07-18 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
2010-07-18 23:02 <wolfspraul> that's gonna be a 1 in a million type of person
2010-07-18 23:02 <gbraad> if you meet the right people, they are listening... and i did meet some of them. ;-)
2010-07-18 23:02 <wolfspraul> sure
2010-07-18 23:05 <gbraad> wolfspraul: what is your vision on the OSHW?
2010-07-18 23:05 <gbraad> seems milkymist endorsed it
2010-07-18 23:05 <wolfspraul> vision?
2010-07-18 23:05 <gbraad> http://freedomdefined.org/OSHW
2010-07-18 23:05 <gbraad> opinion
2010-07-18 23:06 <gbraad> in my sense it is weak!
2010-07-18 23:06 <wolfspraul> I'm a believer in the old IETF approach - implementation first, then standardization
2010-07-18 23:06 <wolfspraul> so that's what I do with copyleft hardware
2010-07-18 23:06 <wolfspraul> does that answer your question?
