  • [02:38:38] * home is at home
  • [02:38:51] <eric___> lol
  • [02:39:02] <home> hey, its late :)
  • [02:39:10] <eric___> east coast too?
  • [02:39:14] <home> CDT
  • [02:39:41] <eric___> ah cool
  • [02:39:42] * home is now known as djlewis
  • [02:39:44] <eric___> so you have the BeagleBoard?
  • [02:39:47] <eric___> or used it?
  • [02:40:01] <djlewis> I have used the BB
  • [02:40:18] <djlewis> got one sitting in front of me turned off.
  • [02:40:34] <eric___> I'm really big into electronics, but havent really dabbled that deep in Linux platforms
  • [02:40:41] <eric___> besides the BugBase ( buglabs.net )
  • [02:40:42] <eric___> anyways
  • [02:40:47] <djlewis> the towo are far apart
  • [02:40:51] <djlewis> two
  • [02:41:09] <eric___> I'm thinking of using the BB to run a Linux GPS processing program of mine
  • [02:41:19] <eric___> but my program relies on the WX framework
  • [02:41:33] <djlewis> I ben deep into electronics for 42 years and linus not so deep for 17 years
  • [02:41:53] <djlewis> so your prog ready?
  • [02:42:09] <eric___> just about
  • [02:42:15] <eric___> should be ready in a few days
  • [02:42:17] <djlewis> whats the question?
  • [02:42:40] <eric___> question is will I have anyproblems uploading a program that uses the WX framework
  • [02:42:54] <eric___> I mean has anyone previously installed the WX framework on the BB
  • [02:43:12] <djlewis> not me but listen a bit..
  • [02:44:30] <eric___> listening
  • [02:45:06] <djlewis> i'm hoping someone will chime in here..
  • [02:45:20] * j_ack_ (n=j_ack@p57A42BD1.dip0.t-ipconnect.de) has joined #beagle
  • [02:46:04] <eric___> I mean from what I understand so far
  • [02:46:12] <eric___> I boot up Ubuntu onto the the beagle board
  • [02:46:19] <eric___> or any of the available distros
  • [02:46:25] <eric___> and then connect a screen
  • [02:46:34] <eric___> and treat it like a regular Linux computer
  • [02:46:36] <eric___> correct?
  • [02:46:59] <djlewis> yes, a 500mHZ 256MB sys
  • [02:47:41] <eric___> and all of it is text console?
  • [02:47:57] <djlewis> if you want, but I run a 1280x1024 LCD
  • [02:48:01] <djlewis> GUI
  • [02:48:10] <eric___> with mouse plugged into USB and stuff
  • [02:48:22] <djlewis> you have many options, yes
  • [02:49:35] <djlewis> have a look here,
  • [02:49:39] <djlewis> http://www.sakoman.com/
  • [02:50:33] <djlewis> He posted this recently on BeagleBoard.org
  • [02:52:08] <eric___> whoa
  • [02:52:26] <djlewis> eric___: so there ya go, lots of possibilities
  • [02:52:42] <eric___> so I could pretty much make a whole app on a regular Linux laptop and then just transfer it to the BB and have it run on a smaller platform!
  • [02:53:08] <djlewis> If you crosscompile it.
  • [02:53:24] <djlewis> seems OE is easiest but there are more options
  • [02:54:17] <eric___> thanks a lot
  • [02:54:21] <eric___> answered my question
  • [02:54:22] <eric___> :)
  • [02:54:29] <eric___> so whats up djlewis?
  • [02:55:00] <djlewis> I'm playing with superkaramba themes on Ubuntu 9.04 wkstn
  • [02:55:17] <djlewis> whch I also use with OE to build my BB apps
  • [02:55:22] <eric___> very cool
  • [02:55:29] <eric___> I have a VM of Ubuntu
  • [02:55:34] <eric___> also VM of WinXP
  • [02:55:37] <djlewis> I dont believe in VM
  • [02:55:50] <djlewis> just get more computers :)
  • [02:55:50] <eric___> one of the best feelings is when my WinXP VM gets a blue screen of death
  • [02:55:52] <eric___> lol
  • [02:56:15] <djlewis> I have 6 near me now and many more :)
  • [02:56:29] <eric___> I have my one measly mac laptop
  • [02:56:38] <eric___> which runs everything and I carry it around with me constantly
  • [02:56:51] <djlewis> Oh, I am soo sorry dude.. :(
  • [02:57:23] <djlewis> really, if it does what ya want then cool.
  • [02:57:44] <djlewis> I say " use the right tool for the job".
  • [02:58:52] <djlewis> eric___: for small apps with simple library requirements you can build locally on BB too.
  • [02:59:13] <eric___> my macbook has been good enough for now
  • [02:59:23] <djlewis> yep, they are cool
  • [02:59:37] <eric___> so what kind of electronics work do you do?
  • [02:59:53] <djlewis> I have been weaning myself from windoze at home.
  • [03:00:15] <eric___> Windows isnt great, but its totally necessary
  • [03:00:37] <djlewis> All kinds. For a living I repair laptops, desktops, larger printers and do networking installs ans setups

  • [03:13:33] <djlewis> tnx
  • [03:16:50] <eric___> I have a ton of projects that have yet to be documented
  • [03:16:57] <eric___> what do you use to document stuff and put it online?
  • [03:17:02] <eric___> I hate hard coding the HTML
  • [03:18:28] <djlewis> I use a template page and mod it manually. I keep my pages simple for more browser compatibility.
  • [03:18:41] <eric___> I used to do that too
  • [03:18:45] <eric___> but its just such a pain
  • [03:18:49] <eric___> my site is narobo.com btw
  • [03:19:16] <djlewis> I find that using the latest and greatest WEB dev tools to be just wrong for my idea of good WEB exchange.

  • [03:24:12] <eric___> thanks
  • [03:24:15] <eric___> needs lots of updates :P
  • [03:24:23] <eric___> i'm looking at wordpress and stuff now
  • [03:26:33] <ds2> ARRRRRGGGGGG using firefox is worse then droping a 5000000lb anvil on your feet
  • [03:27:42] <eric___> why ds2
  • [03:27:45] <eric___> what are you trying to do?
  • [03:29:25] <ds2> I am just trying to browse pages
  • [03:29:48] <ds2> but this PoS insist on popping up and taking focus across virtual desktops
  • [03:29:53] <djlewis> eric___: looks like you design for fun the make it marketable.
  • [03:30:02] <eric___> lol yep!
  • [03:30:04] <eric___> exactly!
  • [03:30:13] <eric___> about three more projects "in the oven"
  • [03:30:19] <eric___> that are a month away from production
  • [03:30:30] <eric___> have some stuff about them on youtube
  • [03:30:50] <eric___> like this
  • [03:30:50] <eric___> http://www.youtube.com/watch?v=YN8afVh7vmQ
  • [03:32:36] <djlewis> eric___: your line vision bot page seems to be doing a lot of loading locally.
  • [03:33:30] <eric___> its an old website
  • [03:33:40] <eric___> needs updates pretty badly
  • [03:34:29] <djlewis> even after the four movie images are loaded. seems my firefox browser is dnld'ing allt he movies to cache?
  • [03:34:39] <eric___> strange
  • [03:34:45] <eric___> all videos are on youtube
  • [03:36:51] <djlewis> It wanst that, the page took forever to fin loading. I then launched the last movie and it opened more dnld.
  • [03:37:10] <djlewis> Oh well. nice line follower.
  • [03:37:43] <eric___> uses CMUcam
  • [03:37:46] <eric___> and AVR micrcontroller
  • [03:37:49] <eric___> big fan of AVRs
  • [03:38:11] <djlewis> U strap a camera onboard for the 'what it sees' view?
  • [03:38:25] <djlewis> I know the cmucam is not that fast
  • [03:38:39] <eric___> its good enough for line following
  • [03:38:44] <eric___> and even basic object tracking
  • [03:38:56] <djlewis> yes, but the onboard view?
  • [03:40:15] <djlewis> after the bot is finished you do a 'onboard view'. this is not the CMUcam.
  • [03:40:50] <eric___> correct
  • [03:40:54] <eric___> its a digicam
  • [03:40:57] <eric___> strapped to it
  • [03:41:01] <djlewis> well there then :P
  • [03:41:11] <eric___> I've seen people use CMUcam to transmit video
  • [03:41:13] <eric___> but again
  • [03:41:19] <eric___> its like 80 x 110 pixels
  • [03:41:19] <eric___> :P
  • [03:41:24] <djlewis> yep, it is too slow for that.
  • [03:41:35] <djlewis> for what you did.
  • [03:41:59] <djlewis> my efforts are to use webcams with BB to drive my robot.
  • [03:42:28] <eric___> how did those go?
  • [03:42:55] <djlewis> so far to slow at 640x480 but it is still early
  • [03:43:15] <djlewis> tried openCV and it is a cpu hog.
  • [03:43:58] <djlewis> my efforts are in visual recognition rather than line following.
  • [03:44:08] <eric___> yea I understand
  • [03:44:12] <eric___> seen RoboRealm?
  • [03:44:34] <djlewis> My bot does real good navigating around as long as there is some kind of walls.
  • [03:44:47] <djlewis> RoboRealm went commercial so it is off my list.
  • [03:45:07] <eric___> theres always older versions of RoboRealm
  • [03:45:10] <eric___> back in the day when it was free

  • [04:10:04] <djlewis> cool
  • [04:10:33] <lemay> its definitely not a very smooth development cycle yet
  • [04:11:26] <lemay> I'm afraid to make changes because I feel like everything will explode unless the stars are perfectly aligned
  • [04:11:41] <djlewis> lots of backups.
  • [04:12:03] <lemay> yea
  • [04:12:08] <lemay> I need more sd cards
  • [04:12:14] <lemay> 1
  • [04:12:16] <lemay> !
  • [04:12:17] <djlewis> hehee, been there
  • [04:12:36] <djlewis> they are relative cheap, get some
  • [04:12:44] <djlewis> did you get a webcam yet?
  • [04:12:59] <lemay> yea, it works great
  • [04:13:16] <djlewis> good, nice to have working tools :)
  • [04:13:46] <lemay> the version of gstreamer under angstrom is a few versions old, and it has some odd errors that dont come up with the more recent stuff used on my PC
  • [04:14:26] <djlewis> ouch!
  • [04:14:30] <lemay> but I imagine that if I try to compile the recent gstreamer releases of gstreamer for angstrom I'll find a few weeks have passed and I've broken everything
  • [04:14:50] <djlewis> I had that with v4l2 and gspca a few months back.
  • [04:15:13] <lemay> and my wife will have left me, my cat will have turned feral, and the pizza in the fridge will have evolved into an intelligent lifeform and be making deals with the tivo to turn off my football recording
  • [04:15:18] <lemay> so I am not going to do it
  • [04:16:17] <lemay> jeez, trying to compile the most recent version of v4l sounds like it could be a whole lot of trouble
  • [04:16:24] <lemay> did your cat turn feral?

  • [04:26:18] <_av500_> google av500 :)

  • [04:30:46] <lemay> cool :)
  • [04:30:59] <_av500_> yepi admit i am not the latest model :)
  • [04:32:25] <_av500_> what do u work on?
  • [04:32:49] <lemay> hobbyist stuff
  • [04:33:28] <lemay> image processing for the most part
  • [04:36:16] <_av500_> on the dsp?
  • [04:37:28] <lemay> not yet, although that is an objective
  • [04:38:44] * robclark (n=robclark@192.91.75.29) Quit ()
  • [04:38:58] <lemay> I wrote some classes to move video from gstreamer into opencv data structures
  • [04:39:25] <lemay> I've been slowly surmounting the linux newbie/cross compiling learning curve
  • [04:39:45] <_av500_> i see :)
  • [04:40:10] <lemay> if I can get what I want done on the cpu I'll start looking at whether or not accelerating the algorithms with the dsp would be fruitful
  • [04:40:15] <lemay> its pretty intimidating
  • [04:40:43] <lemay> the toolchain for the dsp is difficult to figure out
  • [04:41:14] <_av500_> why?
  • [04:41:49] * rbelem (n=rodrigo@pdpc/supporter/active/rbelem) has joined #beagle
  • [04:41:49] <lemay> well, I think because I havent done it yet
  • [04:42:11] <_av500_> ah
  • [04:42:49] <lemay> I have comiled code targetting the DSP once, and it went alright, but I have never done interprocess communications between the cpu and the dsp
  • [04:43:26] <_av500_> there is dsplink to take care bout that
  • [04:43:31] <lemay> I have not tried it or done a lot of research, but at this point it isn't clear where the hooks go to send data/commands between the two
  • [04:43:36] <_av500_> and ce on top of that
  • [04:43:45] <lemay> ce?
  • [04:43:50] <_av500_> codes engine
  • [04:43:55] <_av500_> codec
  • [04:44:31] <_av500_> it is even all in oe...
  • [04:44:41] <lemay> sweet
  • [04:44:57] <lemay> so in your opinion its doable?
  • [04:45:17] <_av500_> there are ce examples that u can just drop some processing stuff in
  • [04:45:43] <_av500_> data in out alredy taken care of
  • [04:46:39] <lemay> that sounds doable ... do you have any recommendations for what I should read/google to learn more?
  • [04:47:01] <_av500_> dsplink and codec engine
  • [04:47:38] <_av500_> try to run the examples
  • [04:48:19] <lemay> examples are always the best way to learn
  • [04:48:40] <lemay> I have a basic question about the DSP ... what does it do that makes it faster than the CPU?
  • [04:49:00] <lemay> is it simply faster, 64 bit multiplies?
  • [04:49:15] <_av500_> it depends
  • [04:49:30] <_av500_> for general purpopse stuff it is not faster
  • [04:49:46] <lemay> roger - conditionals and what not
  • [04:49:49] <_av500_> for some stuff it can be
  • [04:50:25] <_av500_> but - it runs in parallel to the cpu!
  • [04:50:31] <lemay> multithreading!
  • [04:50:44] <_av500_> so u can split the work
  • [04:51:08] <_av500_> but of course it is more tricky to code...
  • [04:51:49] <lemay> I can be tricky! The only thing trickier is my pizza, when it evolves intelligence and teams up with the tivo...
  • [04:52:04] <lemay> was that out loud?

  • [14:06:50] <av500> no
  • [14:07:10] <av500> I booted it once with a prebuilt IT image, that was all :(
  • [14:07:23] <mru> white lcd could simply mean it hasn't be enabled at all
  • [14:07:48] <rsv> but i put some debug statements in the panel driver - and all spi writes are successful
  • [14:08:41] <rsv> mru: anything that i need to check?
  • [14:08:50] <mru> to get something sensible on the lcd you need the panel driver and the framebuffer driver activated

  • [14:09:39] <rsv> i have a panel driver and a fb driver activated
  • [14:09:58] <mru> then I don't know

  • [14:22:02] <_koen_1> Christos_N: depends on the branch you are looking at

  • [14:26:08] <_koen_1> yes
  • [14:26:20] <Christos_N> ok
