Jul 08 03:00:31 <prpplague^2> are you sure? got a datatsheet on the device?
Jul 08 03:02:01 <MrCurious> thats what the datasheet said IIRC
Jul 08 03:02:43 <MrCurious> but the garbled data has the same general pattern as the data i am expecting, but as if its 6 or 7 bits instead of 8
Jul 08 03:03:17 <MrCurious> i connected the GPS to a FTDI board and read from it on my mac with screen /dev/tty.usbblahblah 9600
Jul 08 03:03:51 <MrCurious> i suspect my next step will be to write a C program to read from teh serial port where i can control all the speed parity stop bit settings
Jul 08 03:05:58 <prpplague^2> MrCurious: if it is indeed +5V TTL then it will not work on the RS-232 DB-9 on the panda
Jul 08 03:06:17 <MrCurious> the db9 is expecting 0,12v?
Jul 08 03:07:07 <prpplague^2> MrCurious: -12 and +12
Jul 08 03:07:13 <prpplague^2> MrCurious: rs-232
Jul 08 03:07:21 <MrCurious> i see :(
Jul 08 03:07:41 <MrCurious> guess i will need to switch to an alternative method
Jul 08 03:07:54 <MrCurious> suppose this is a good use for my ttl serial to BT boards
Jul 08 03:08:15 <prpplague^2> MrCurious: why not just uses a level shifter and use the uart on the expansion header?
Jul 08 03:08:59 <MrCurious> what voltages is that uart expecting? as this GPS can do either 5v or 3.3v
Jul 08 03:09:20 <MrCurious> and that would be much better than resorting to learning how to use BT on a panda :P
Jul 08 03:09:38 <MrCurious> coincidentally, i have some level shifters in route from sparkfun as we speak
Jul 08 03:09:50 <prpplague^2> MrCurious: the all I/O on the panda operates at 1.8V
Jul 08 03:09:59 <MrCurious> ahh, liek a gumstix
Jul 08 03:10:07 <prpplague^2> MrCurious: you'll need something like a txs0102 to shift to 3.3v or 5v
Jul 08 03:10:10 <MrCurious> all i/o, *except for usb...
Jul 08 03:10:48 <MrCurious> http://www.sparkfun.com/products/8745
Jul 08 03:10:51 <MrCurious> or like that...
Jul 08 03:11:01 <MrCurious> cheap, and made very easy to work with
Jul 08 03:11:23 <MrCurious> and since the GPS is send only, only one level converter will be needed :)
Jul 08 03:12:20 <MrCurious> prpplague: thanks for the tip about the expansion header. that will make this much much easier
Jul 08 03:13:20 <prpplague^2> prpplague^2: yea if arent into doing the wiring yourself
Jul 08 03:14:08 * prpplague^2 has a spool of about 10k txs0102's in the garage
Jul 08 03:15:36 <MrCurious> i will wire the things i understand
Jul 08 03:15:50 <MrCurious> fabricate PCB's for the things i pretend to know
Jul 08 03:16:02 <MrCurious> and lean on pre-built when its cost effective
Jul 08 03:17:14 <prpplague^2> indeed
Jul 08 03:17:41 <prpplague^2> MrCurious: http://www.beldynsys.com/quad.htm
Jul 08 03:17:47 <prpplague^2> MrCurious: great for prototyping
Jul 08 03:17:50 <MrCurious> i just want to make an interesting robot. i have discovered while on this journey, starting in the land of ATMEL that there are many rabbit holes one can fall down into
Jul 08 03:17:54 <prpplague^2> worthy investment
Jul 08 03:18:04 <prpplague^2> MrCurious: indeed
Jul 08 03:18:17 <prpplague^2> MrCurious: true with just about any technology field
Jul 08 03:18:40 <MrCurious> i have some QFN or TQFP accelerometers, gyros and magnetometers i have been meaning to make into a 9dof
Jul 08 03:19:09 <MrCurious> for prototyping, eagle + dorkbotpdx works better for me than prototyping boards
Jul 08 03:22:17 <prpplague^2> hehe, each to his own, i only do a board design if i really expect to need more than a handful
Jul 08 03:23:34 <MrCurious> starting to get the feeling that OpenNI is Biased against ARM in favor of intel
Jul 08 03:24:43 <prpplague^2> openni?
Jul 08 03:25:53 <MrCurious> http://www.openni.org/
Jul 08 03:25:59 <MrCurious> http://www.openni.org/gallyt
Jul 08 03:26:07 <MrCurious> the videos betray its purpose faster than the words
Jul 08 03:26:37 <prpplague^2> ahh interesting
Jul 08 03:27:06 <MrCurious> i was impressed last night, a pandaboard + usb hard drive + kinect + libfreenect running cvdemo had a usable frame rate
Jul 08 03:27:22 <MrCurious> running ubuntu 11.04 (known to have 1/2 speed usb)
Jul 08 03:33:03 <MrCurious> i see why it doesnt work on ARM, it relies on SSE2 and SSE3 instructions
Jul 08 09:32:31 <ashwinipatankar> I am running a code on arm kernel in qemu, can any one advice me how to calculate the mips for the same, I am having gprof output
Jul 08 09:38:15 <stm__> hi all
Jul 08 09:38:25 <stm__> during booting procees
Jul 08 09:38:38 <stm__> i got the problem mounting none on dev
Jul 08 09:39:33 <stm__> iam running ubuntu
Jul 08 09:39:47 <stm__> and now i changed uImage
Jul 08 09:39:53 <stm__> and updated initramfs
Jul 08 09:40:36 <stm__> do i need to edit some other files inorder to mount the dev
Jul 08 09:40:52 <ashwinipatankar> I am running a code on arm kernel in qemu, can any one advice me how to calculate the mips for the same, I am having gprof output
Jul 08 09:45:20 <hrw> ashwinipatankar: do not assume anything speed related in qemu
Jul 08 09:47:35 <ashwinipatankar> hrw: I agree , but how to calculate mips, my code is running, I am having gprof output for the same, even on desktop also (outside qemu) how will I calculate mips
Jul 08 09:47:51 <hrw> no idea
Jul 08 09:48:02 <hrw> I do not believe in mips as speed unit
Jul 08 09:49:01 <hrw> what is faster? armv5 1.2GHz or armv7 0.6MHz?
Jul 08 09:49:05 <hrw> what is faster? armv5 1.2GHz or armv7 0.6GHz?
Jul 08 09:50:08 <ashwinipatankar> hrw: MIPS with respect to specific code, so that we can know how many instructions it needs to execute in per second for real time operations
Jul 08 09:54:57 <persia> hrw, Depends on workload.
Jul 08 09:55:33 <persia> ashwinipatankar, Map out your codepaths, then see how long it takes to execute your code.  Mind you, this won't be very interesting, especially for qemu.
Jul 08 11:47:01 <blu_> hi all
Jul 08 11:47:37 <blu_> can anyone tell me is there any spi driver on 11.04 ubuntu on arm ?
Jul 08 16:13:15 <stm__> hi all
Jul 08 16:14:19 <stm__> any link to build ubuntu filesystfrom scratchem
Jul 08 16:14:28 <stm__> scratch
Jul 08 16:42:48 <GrueMaster> stm__: See https://wiki.ubuntu.com/ARM/ and read RootFromScratch section.
Jul 08 17:00:49 <gaeel> hey people, anyone had any luck with lubuntu or similar on a low-end ARM-based sub-netbook?
Jul 08 17:01:31 <gaeel> My grandmother got one for free, and I'm thinking of installing something that will work for her email and web-browsing needs
Jul 08 17:02:54 <gaeel> Was considering chromium too, but it seems unstable so far
Jul 08 17:19:26 <diwic> gaeel, out of curiousity, what model was that arm-based subnetbook?
Jul 08 17:22:15 <gaeel> It's a Tec T-Book
Jul 08 17:22:26 <gaeel> Googling it yields little to no info
Jul 08 17:23:14 <gaeel> I'm thinking it's a generic machine branded by Tec, for distribution as a cheap machine
Jul 08 17:23:32 <diwic> gaeel, then I assume that Linux has no support for its hardware, but I don't know
Jul 08 17:23:37 <gaeel> It comes pre-installed with Windows CE and a handful of software
Jul 08 17:25:12 <gaeel> I want to give it a go for the kicks, it comes with a reset SD card, so I can always nuke it and put it back if I brick it
Jul 08 17:25:27 <gaeel> I'm mostly pondering which distro to try
Jul 08 17:29:04 <ogra_> ubuntu wont support armv5 (which that system likely is)
Jul 08 17:29:10 <ogra_> use debian
Jul 08 17:29:23 <ogra_> or some other distro that supports v5
Jul 08 17:29:29 <gaeel> What I was thinking
Jul 08 17:30:21 <gaeel> I don't need anything to state-of-the-art, since it's for my grandmother, but  was wondering if Ubuntu had anything to offer
Jul 08 17:31:00 <ogra_> not for that type of arm anymore
Jul 08 17:31:10 <gaeel> righto
Jul 08 18:26:27 <prpplague> FYI, for anyone interested, today is the last day to submit a proposal for ELC-E
Jul 08 19:33:36 <GrueMaster> ELC-E?
Jul 08 20:16:27 <rsalveti> GrueMaster: https://blueprints.launchpad.net/linaro-ubuntu/+spec/o-uboot-spl-usb-support-omap4
Jul 08 20:16:44 <rsalveti> GrueMaster: hopefully when done u-boot spl will have a similar functionality as omap4boot
Jul 08 20:16:54 <rsalveti> but all at the same tree :-)
Jul 08 20:17:05 <rsalveti> and then we can just kill x-loader ;-)
Jul 08 20:17:10 <rsalveti> thanks to jcrigby
Jul 08 20:34:19 <GrueMaster> sweet.
Jul 09 00:53:32 <MrCurious> wow. on ubuntu 11.04, if i run system monitor full screen, eventually it stops, until i wiggle the mouse
