Jan 25 06:48:43 <amin> hi
Jan 25 06:49:18 <amin> does Beaglebone Black have adc? how many bits?
Jan 25 07:13:50 <_av500_> 10 or so
Jan 25 07:15:53 <srin> how to  read the register value in beagle board using mmap
Jan 25 07:31:48 <_av500_> maybe you should practice on an Arduino first
Jan 25 09:48:47 <CrossXBones> Hello all, I had a quick question for anyone who might know: is there any way to do HDMI input to the Beaglebone Black, USB webcam works okay, but I wanted to use a better camera
Jan 25 09:50:12 <tbr> no
Jan 25 09:50:57 <CrossXBones> Even using the GPIOs?
Jan 25 09:51:37 <tbr> by far not fast enough
Jan 25 09:51:53 <CrossXBones> That's what I thought, but I figured I'd check
Jan 25 09:52:00 <tbr> you might be able with the GPMC and a lot of glue electronics and software
Jan 25 09:54:35 <CrossXBones> I've done a bunch of hacking about on the software side, but not sure I have the skills for too much on the hardware side ... thanks for the response :)
Jan 25 10:10:18 <VSS> has anybody used opencv in python on BBB?
Jan 25 10:16:56 <tbr> "like on your desktop" just with less computational power
Jan 25 10:25:30 <VSS> ??
Jan 25 14:20:15 <BeagleBonny> hello!
Jan 25 14:20:22 <BeagleBonny> is anyone here?
Jan 25 14:20:39 <BeagleBonny> i have a question that un-answered :)
Jan 25 14:21:02 <BeagleBonny> how can i install nuxeo on beaglebone black :s
Jan 25 14:22:44 <BeagleBonny> anyone?
Jan 25 14:45:26 <_av500_> nuwhat?
Jan 25 14:47:33 <_av500_> its java
Jan 25 14:47:51 <_av500_> just install some java runtime and it will run, no?
Jan 25 14:47:55 <veremit> why on earth are people java-obsessed
Jan 25 14:48:05 <veremit> he left btw .. too impatient
Jan 25 14:49:03 <_av500_> of course
Jan 25 18:34:34 <rocky|arch> Can someone help me out with the device tree?  I'm trying to set up the PRU inputs through R31, and P9_26's mode isn't being set for Some Reason(tm). https://github.com/Rose-Hulman-ROBO4xx/1314-BeagleBone-Quadcopter/blob/master/code/i2c_bitbang/pru_sw/devicetree/BB-PRU.dts
Jan 25 18:35:34 <veremit> rocky|arch .. what is reported in dmesg when the DTS is bein loaded?
Jan 25 18:43:15 <rocky|arch> I'm running into some issues loading the dto that I didn't yesterday.  This could take a bit.
Jan 25 18:51:38 <rocky|arch> It is failing for all device trees!  Here's dmesg from trying to load uart4, all the dmesg errors are looking the same :/ http://pastiebin.com/52e407b506b27
Jan 25 18:53:13 <rocky|arch> after doing "echo BB-UART4-00A0 > /sys/devices/bone_capemgr.8/slots
Jan 25 18:53:20 <rocky|arch> I get "no such file or directory"
Jan 25 18:57:20 <veremit> rocky|arch .. you sure your kernel is configured right for dtbs?
Jan 25 18:57:23 <rocky|arch> I retract what I said about no device tree overlays loading, the PRU one loaded fine.
Jan 25 18:58:12 <rocky|arch> It's the angstrom september 5th image.  I never had these problems with it before.
Jan 25 18:58:43 <veremit> double-checked your syntax
Jan 25 18:58:57 <veremit> files all in the right places ..
Jan 25 19:09:41 <rocky|arch> veremit: I'm putting the dtbo file in /lib/firmware.  I haven't found any good guides for device tree syntax, so I've been modifying other people's.  I was hoping that since it was mostly working, someone could help me get that last pin to behave.
Jan 25 19:11:41 <veremit> its not a science I fully understand .. and there are no tools to help either
Jan 25 19:12:03 <veremit> have you seen the guides online?
Jan 25 19:12:14 <rocky|arch> no, can you point me to them?
Jan 25 19:12:26 <rocky|arch> well, actually, I guess it depends on which guide you are talking about
Jan 25 19:12:50 <veremit> this one I usually post as a starting point ..http://learn.adafruit.com/introduction-to-the-beaglebone-black-device-tree/overview
Jan 25 19:12:52 <rocky|arch> the overlay's I've produced based on most guides only get some pins working.
Jan 25 19:13:32 <veremit> if you keep visiting here .. there are a few people who've worked with the PRUs shoul dbe abl eto help you
Jan 25 19:13:50 <rocky|arch> Ok
Jan 25 19:20:02 <rocky|arch> veremit: I'm going to follow that guide and try to rewrite my overlay.  It is going into more detail and explaining most of what's going on, which is very nice.
Jan 25 19:20:25 <rocky|arch> compared to other guides, where it's pretty much, "I have no idea what's going on, but this worked for my project!"
Jan 25 19:20:43 <veremit> lol thats why I quite like adafruit .. its .. not basic but instructive.
Jan 25 19:25:03 <rocky|arch> veremit: do you know what the "target" means?  Is it something that just helps figure out what's going on in the logs, or does it have real semantic value to the device tree?
Jan 25 19:25:40 <veremit> I think 'target' as used in their example is like a keyword
Jan 25 19:36:00 <rocky|arch> ls
Jan 25 19:36:04 <rocky|arch> derp
Jan 25 19:51:13 <rocky|arch> ermagerd veremit I think it's working
Jan 25 19:51:47 <veremit> excellent
Jan 25 20:01:50 <poagester> would anyone happen to know if the bmp085 driver is compatible with the bmp180? It looks like it would, but if anyone has tried let me know
Jan 25 20:02:34 <electroman> hi
Jan 25 20:03:01 <electroman> hi
Jan 25 20:03:16 <electroman> am i alone here??
Jan 25 20:03:26 <poagester> no
Jan 25 20:04:09 <rocky|arch> dat user list
Jan 25 20:04:13 <electroman> is there someone here that know when will the beaglebone black will be available somewhere??
Jan 25 20:04:30 <poagester> its out in the us
Jan 25 20:04:49 <veremit> production has been increased to meet demain
Jan 25 20:04:51 <electroman> yes but it is backorder everywhere
Jan 25 20:04:54 <veremit> demand**
Jan 25 20:05:02 <poagester> microcenter.com
Jan 25 20:05:07 <veremit> electroman.. where you looking?
Jan 25 20:05:23 <electroman> all the recommended site from the beaglebone site
Jan 25 20:05:34 <poagester> microcenter.com
Jan 25 20:06:11 <veremit> aint gonna help if outside the US :P
Jan 25 20:06:22 <electroman> i'm in canada
Jan 25 20:06:40 <electroman> i just searched microcenter.com and it is not even listed
Jan 25 20:07:50 <poagester> thats odd, it's where i bought mine. call one of the stores, they might do some kind of special shipping
Jan 25 20:08:07 <veremit> electroman .. think its a case of sit and wait
Jan 25 20:08:19 <tbr> radioshack supposedly had some too
Jan 25 20:08:30 <veremit> or spam circuitco and tell 'em to work their hamsters faster :P lol
Jan 25 20:08:41 <electroman> lol
Jan 25 20:08:43 <poagester> +1
Jan 25 20:08:55 <electroman> it might be the right thing to do !!!! ;P
Jan 25 20:09:33 <rocky|arch> jameco says it's going to ship in 13 days
Jan 25 20:09:52 <veremit> last I heard they're now making 7k units/week
Jan 25 20:10:03 <rocky|arch> wasn't the order size something like 100k?
Jan 25 20:10:06 <veremit> but they got a BIIIIIIG backlog to fill
Jan 25 20:10:10 <rocky|arch> yeah...
Jan 25 20:10:26 <electroman> hmmmmm
Jan 25 20:10:54 <veremit> 5k/week just wasn't cutting it when big orders kept nuking stock
Jan 25 20:11:16 <veremit> so I think they've put caps on order quantity lol
Jan 25 20:17:35 <veremit> http://canada.newark.com/circuitco/bb-bblk-000/dev-board-am3358-59-arm-mpu-beaglebone/dp/65W6016
Jan 25 20:17:55 <veremit> wait, whine and hope :D lol
Jan 25 20:18:16 <veremit> or wine, if you prefer .. beer ofc another option :D
Jan 25 20:22:44 <veremit> ok I gotta bbiab
Jan 25 20:53:23 <mnt_real> electroman: if you were in montreal I could land my BBB to you for couple days
Jan 25 20:54:26 <electroman> i'm close from Gatineau, and i need one board asap to begin my robot development
Jan 25 20:55:30 <electroman> but thank's mnt_real
Jan 25 20:55:56 <electroman> well. i'll have to wait like everybody....
Jan 25 20:56:51 <mnt_real> electroman: np, let me know if it becomes emergency and you can't get any ..
Jan 25 20:57:40 <electroman> ok thank's a lot, i'm doing phone call right now and i may be able to find one.... i'll see
Jan 25 21:06:23 <mnt_real> electroman: good luck ...
Jan 25 21:48:57 <electroman> Wouhou just bought the last one at 45$!!!!!!!!!!!!
Jan 25 22:36:11 <mnt_real> electroman: where did you get it from ?
Jan 25 22:48:32 <slug> hi, how can I list the files in eMMC /boot from u-boot ? what device should i pass to the 'ls' command ?
Jan 25 23:04:48 <CareBear\> slug : uEnv.txt and friends?
Jan 25 23:04:59 <CareBear\> slug : mount /dev/mmcblk0p1 somewhere and then ls somewhere
Jan 25 23:05:24 <slug> CareBear\: i'm at the u-boot prompt (serial console)
Jan 25 23:05:35 <CareBear\> aha
Jan 25 23:05:43 <CareBear\> dunno about that
Jan 25 23:05:46 <slug> CareBear\: i want to boot a different kernel, than the one set in uEnv.txt
Jan 25 23:13:50 <slug> CareBear\: http://www.crashcourse.ca/wiki/index.php/U-Boot_Commands_on_the_BBB
Jan 25 23:14:02 <slug> CareBear\: at the end, i can list the files.

Jan 26 02:25:31 <gburca> Does anyone know if it's possible to modify the mode of a pin using /dev/mem?
Jan 26 02:26:08 <gburca> I want to switch it from Mode7 to Mode6, but it doesn't seem to work.
Jan 26 02:26:39 <gburca> The GPIO pad control seems to be read-only.
Jan 26 02:26:40 <veremit> eww
Jan 26 02:26:46 <veremit> I should think so :p
Jan 26 02:27:04 <veremit> reconfiguring on the fly is rather dangerous
Jan 26 02:27:17 <veremit> imagine doin that with some video or uart or usb pins ....
Jan 26 02:27:44 <gburca> I have a sensor that uses a proprietary 1-wire protocol.
Jan 26 02:28:04 <veremit> there are 1wire libs ..
Jan 26 02:28:15 <gburca> I configure the GPIO as output to wake-up the sensor, then switch it to input to read.
Jan 26 02:28:31 <gburca> This one doesn't use the standard (Dallas?) 1-wire protocol.
Jan 26 02:28:58 <gburca> The timing is so tight (a few us) that I have to read using the PRU.
Jan 26 02:29:16 <veremit> yeah you won't get any decent response without the pru
Jan 26 02:29:31 <gburca> Everything "works", except after I wake it up, I can't change the pin mode to 6 so that the PRU can read it.
Jan 26 02:29:43 <veremit> you can;t configure it as bi-dir .. ie. i/o ?
Jan 26 02:30:02 <gburca> No. Not for the PRU.
Jan 26 02:30:29 <gburca> It maps GPI and GPO to different registers (r31 and r30 respectively).
Jan 26 02:30:32 <veremit> I dont know much about the prus .. but I should imagine there's gotta be a way to have bidir comms
Jan 26 02:30:33 <gburca> Kinda sucks.
Jan 26 02:30:48 <veremit> can't map to both?! [shudder]
Jan 26 02:30:52 <gburca> nope
Jan 26 02:31:26 <gburca> But that's OK. I can do the output from the OMAP, then the input from the PRU, if I could only switch the pinmux on the fly.
Jan 26 02:32:18 <gburca> I think I can change the pinmux using sysfs, but that's too slow.
Jan 26 02:32:30 <gburca> I was hoping I can do it using /dev/mem
Jan 26 02:33:45 <gburca> BTW, the sensor is the DHT22 (temperature/humidity).
Jan 26 02:34:05 <veremit> google seems to have an article thus... someone doin something similar .. https://groups.google.com/forum/#!topic/beagleboard/35ZXP82EQjA
Jan 26 02:34:15 <veremit> can't quite parse the links myself though
Jan 26 02:34:27 <veremit> interrupt in userspace/pru seems to be one solution
Jan 26 02:34:34 <gburca> It seems to work well enough with Arduino, but on the BBB there's too many latencies.
Jan 26 02:34:42 <poagester> does anyone know which pin 0x77 is? i am trying to connect to the expected i2c. also, where can i find all of these hex addresses?
Jan 26 02:35:37 <veremit> beagle is not built for io
Jan 26 02:35:50 <veremit> poagester .. System Reference Manual
Jan 26 02:36:22 <veremit> start with the one with the beagle .. then go towards TI ones :p
Jan 26 02:36:32 <gburca> veremit: that's an interesting link. Thanks.
Jan 26 02:36:43 <veremit> hope it helps get you in right direction
Jan 26 02:38:34 <johnwalkr> poagester: BMP085?
Jan 26 02:39:24 <poagester> no tsl2561 and bmp180
Jan 26 02:40:17 <johnwalkr> and one of them uses address 0x77?
Jan 26 02:40:40 <poagester> johnwalkr: i got the tsl to work with python, but i need to migrate it to the server
Jan 26 02:40:53 <poagester> bmp085 does
Jan 26 02:40:57 <poagester> for the driver
Jan 26 02:41:26 <veremit> ok my eyes are gettin sore .. nite all .. back tomorrow! I-)
Jan 26 02:42:47 <johnwalkr> ok..
Jan 26 02:43:06 <johnwalkr> well 0x77 is an adress not a pin, but it sounds like you already have teh devices wired up to the BBB?
Jan 26 02:44:12 <johnwalkr> both devices would normally be connected to one i2c bus on the BBB
Jan 26 02:44:24 <johnwalkr> then you can addres them by device address and register addresses
Jan 26 02:58:18 <poagester> johnwalkr: sorry i was reading. i only have the tsl hooked up and i do get readings from this example: https://github.com/lamunozh/BeagleBone/blob/master/tsl2561
Jan 26 02:58:26 <poagester> its really helpful
