Dec 23 03:43:54 <sumangal> can i share my internet connection with beaglebone black over ethernet in ubuntu?
Dec 23 04:46:45 <kutang> anyone here?
Dec 23 04:49:07 <vagrantc> kutang: someoone's more likely to respond to a question about a specific issue
Dec 23 04:49:37 <vagrantc> kutang: so just ask your question(s) and wait patiently
Dec 23 04:51:55 <grantsmith> is it possible to run multiple RFID scanners on one BBB ?
Dec 23 05:11:26 <myself> what sort of scanners? link to the one you're considering would help, bonus if page includes datasheet
Dec 23 05:13:59 <av500> these scanners: http://www.imdb.com/title/tt0081455/
Dec 23 05:31:08 <myself> Was expecting this one: http://www.imdb.com/title/tt0405296
Dec 23 06:21:34 <av500> myself: we, he wanted multiple
Dec 23 06:57:10 <bpetersen> So I have plugged in my BeagleBoneBlack, how do I issue commands to it?
Dec 23 06:57:33 <bpetersen> I've tried going to http://192.168.7.2 but that doesn't exist
Dec 23 06:58:10 <bpetersen> I have a serial terminal program but it can't find the BBB COM port
Dec 23 06:59:18 <LetoThe2nd> bpetersen: well are you running a sane OS (e.g., linux)?
Dec 23 06:59:55 <bpetersen> I downloaded Angstrom Distribution (BeagleBone Black - 2GB eMMC) 2013-09-04 - more info - bittorrent and put it on the microSD card
Dec 23 07:00:20 <LetoThe2nd> what is running on your host?
Dec 23 07:00:37 <bpetersen> I put the microSD card in the BBB, held down the USER BOOT button and powered on the BBB
Dec 23 07:00:42 <bpetersen> Angstrom
Dec 23 07:01:09 <bpetersen> I have Windows 7 (already downloaded drivers) and Ubuntu 13.04
Dec 23 07:01:54 <bpetersen> I have worked with the BeagleBone and never had issues. I bought a BBB, ran the command opkg update and it blew up. I just got around to fixing it now
Dec 23 07:01:56 <LetoThe2nd> can't tell anything about windows (with or without drivers), as i've never used it.
Dec 23 07:02:14 <bpetersen> How do you connect to it?
Dec 23 07:02:18 <LetoThe2nd> ah ok. well opkg upgrade is rarely a good idea.
Dec 23 07:02:28 <bpetersen> haha
Dec 23 07:02:31 <bpetersen> I realize that
Dec 23 07:03:16 <LetoThe2nd> but no serial debug cable, i assume?
Dec 23 07:03:35 <bpetersen> I am new to this and I am not sure what that is
Dec 23 07:03:41 <LetoThe2nd> ok.
Dec 23 07:04:06 <LetoThe2nd> usually just writing the image to micro sd, inserting, then powering on should do the trick
Dec 23 07:05:14 <bpetersen> When I plug it in, it seems like its is working (Heart Beat LED is flashing normally, etc.). I just can't figure out how to make a connection to it
Dec 23 07:06:20 <bpetersen> Should I replace the Angstrom Distribution from:
Dec 23 07:06:35 <LetoThe2nd> under linux you could see if it becomes alive, when it enumerates usb devices.
Dec 23 07:06:38 <bpetersen> Angstrom Distribution (BeagleBone Black - 2GB eMMC) 2013-09-04
Dec 23 07:06:48 <bpetersen> to: Angstrom Distribution (BeagleBone, BeagleBone Black - 4GB SD) 2013-06-20 - more info
Dec 23 07:06:49 <bpetersen> ?
Dec 23 07:08:01 <LetoThe2nd> i personally would try the latest emmc  flasher image
Dec 23 11:01:28 <OndraCZ> Hi guys, is there any project, that uses BBB to control a aut. robot and send data over WIFI to laptop?
Dec 23 11:01:40 <OndraCZ> *an
Dec 23 14:11:32 <thews> people are odd
Dec 23 14:12:18 <thews> is there any project that uses the hardware?
Dec 23 14:12:26 <thews> No way.
Dec 23 14:18:29 <Shadyman> wat
Dec 23 14:18:47 <Hubcap> Hey guys.. Could someone tell me if the BeagleBone Black can be powered over USB?
Dec 23 14:19:45 <anujdeshpande> Hubcap: yes.
Dec 23 14:22:39 <Hubcap> so you could plug a usb power cable into the usb port of the bb black or would you have to hook a special usb cable up to its 5v slot?
Dec 23 14:23:18 <anujdeshpande> Hubcap: BBB has 2 USB ports. one of them is the micro USB standard
Dec 23 14:24:16 <anujdeshpande> you should've got a USB A to micro wire with your BBB ( it's easily available too anyways)
Dec 23 14:24:16 <anujdeshpande> you can power it up by connecting it to any USB wall charger or your computer's USB port. will work fine
Dec 23 14:24:37 <anujdeshpande> you don't need to use any special USB to barrel jack converter
Dec 23 14:24:49 <Hubcap> ohh thanks alot.. looks like i was too dumb to realise it had two
Dec 23 14:24:58 <anujdeshpande> np
Dec 23 14:40:05 <prpplague> thews: a project that uses what hardware?
Dec 23 14:40:43 <thews> someone asked if anyone had a project that "controlled a bot" and used wifi
Dec 23 14:40:58 <prpplague> ahh
Dec 23 14:41:33 <thews> prpplague: theres a lot of lack of googling :)
Dec 23 14:44:41 <prpplague> thews: indeed
Dec 23 14:46:35 <thews> https://gist.github.com/justinledwards/8091295#file-weather-py-L1    works with some really cheap ebay i2c lcd backpacks
Dec 23 14:47:07 <thews> had to find a library that had the expander pins mapped out
Dec 23 14:48:04 <thews> also made it turn the backlight off during sleeping hours
Dec 23 14:50:39 <thews> I wanted to use pypy, but had problems with smbus
Dec 23 14:52:38 <prpplague> thews: create a wiki page on elinux.org
Dec 23 14:52:54 <thews> prpplague: I'll check into that in a bit,  hadn't thought of it
Dec 23 14:53:21 <prpplague> thews: good place to document a project and make it of use to other people, it's free to register
Dec 23 14:54:32 <thews> I made an account
Dec 23 15:00:14 <thews> prpplague any idea why the CPU usage is high (5%) while just waiting on a few bytes from 1-wire?   it's utilized by irq
Dec 23 15:00:47 <thews>     0 S   1.6  0.0   2:55.35 irq/46-4819c000
Dec 23 15:01:02 <thews> 5% is about the highest I've seen it
Dec 23 15:44:08 <thews> not sure how to add a page to the wiki
Dec 23 15:48:14 <anujdeshpande> thews: just go to the url, it'll say that such a page doesn't exist.
Dec 23 15:48:22 <thews> ahh
Dec 23 15:48:27 <anujdeshpande> and you'll have some option to create it
Dec 23 16:04:18 <thews> anujdeshpande: got it,  started working on it now, but I have to jump back to it a bunch,  other work :S
Dec 23 16:12:35 <thews> prpplague: started it here http://elinux.org/BeagleBone/I2CLCDDemo
Dec 23 16:13:29 <prpplague> dandy
Dec 23 16:28:39 <bitnumus> hi can anyone recommend a 3.2" + screen compat with BBB that isnt a cape?
Dec 23 16:29:42 <prpplague> bitnumus: the only other way to add a LCD other than via a cape is via the HDMI interface
Dec 23 16:29:52 <prpplague> bitnumus: is that what you are asking to do?
Dec 23 16:29:55 <thews> bitnumus: it'd probably be best to check the schematics of the screen capes and see the specs on them and use that as a guide
Dec 23 16:30:34 <thews> if you're okay with a larger screen, get a lapdock,  can't beat $40 bucks on ebay
Dec 23 16:31:58 <bitnumus> prpplague, no, there are SPI interface screens out there, so its not the only option
Dec 23 16:32:02 <bitnumus> HDMI options are too expensive
Dec 23 16:32:18 <bitnumus> 3.2" - 4.3" is what i need really
Dec 23 16:32:31 <prpplague> bitnumus: well adding a SPI LCD would be done through the cape interfaces
Dec 23 16:32:36 <av500> 4.3" in SPI I dont know
Dec 23 16:32:49 <av500> prpplague: yes, he just does not want it ON the cape
Dec 23 16:33:01 <bitnumus> prpplague, i'm under the impression that 'capes' generally take up all P8-P9 headers
Dec 23 16:33:01 <av500> we need a extensionCordCape
Dec 23 16:33:03 <bitnumus> which is what i dont want
Dec 23 16:33:10 <av500> bitnumus: put your screen on top
Dec 23 16:33:15 <av500> other capes underneath
Dec 23 16:33:23 <av500> or get a breakout cape
Dec 23 16:33:26 <av500> -or
Dec 23 16:33:29 * prpplague notes the question was very vague
Dec 23 16:33:30 <bitnumus> atm i've bent pins on the cape to free up the pins
Dec 23 16:33:33 <bitnumus> but this is shitty
Dec 23 16:33:37 <av500> get a breakout cape
Dec 23 16:33:42 <av500> with "ears" left and right
Dec 23 16:33:44 <bitnumus> means more height on my device
Dec 23 16:33:46 <bitnumus> :(
Dec 23 16:33:51 <prpplague> bitnumus: how far appart from the black do you want to place the lcd?
Dec 23 16:34:05 <bitnumus> RPI has a few screens that have drivers written for, no such sources like this for the BBB?
Dec 23 16:34:05 <av500> this far |<------------------------------------------------------------------------------------------------------>|
Dec 23 16:34:15 <av500> bitnumus: the drivers will work as well
Dec 23 16:34:30 <prpplague> bitnumus: hundreds, far far more than RPi
Dec 23 16:34:32 <bitnumus> av500, yes maybe
Dec 23 16:35:27 <bitnumus> so nothing specifically documented then :)
Dec 23 16:35:33 <bitnumus> i'm fed up of looking at screens lol
Dec 23 16:35:56 <prpplague> bitnumus: make if you tell me what exactly you are trying to accomplish i can give more detailed suggestion
Dec 23 16:36:08 <bitnumus> prpplague, sure
Dec 23 16:36:48 <bitnumus> i'm trying to find a screen thats capable of displaying a QRcode with a small-medium amount of data, i think a 3.2" will be fine for this. I'd like to fit this screen and the BBB in as small an enclosure as possible
Dec 23 16:37:02 <bitnumus> and i want free/easy access to all the pins the screen doesn't use
Dec 23 16:37:14 <thews> bitnumus: what do you want on the screen?
Dec 23 16:37:20 <bitnumus> atm i have a 4DCAPE-43T
Dec 23 16:37:36 <bitnumus> thews, QT application
Dec 23 16:37:39 <thews> this morning I've been writing this up at the suggestion of prpplague http://elinux.org/BeagleBone/I2CLCDDemo#Software
Dec 23 16:37:39 <thews> ahh
Dec 23 16:37:44 <thews> this is just for text
Dec 23 16:37:46 <thews> but super cehap
Dec 23 16:37:47 <bitnumus> nothing too fancy apart frmo the QR code which needs a certain res
Dec 23 16:38:39 <bitnumus> atm i'm working with  480x272
Dec 23 16:38:47 <prpplague> bitnumus: so why not put a proto cape in between the lcd cape and the black?
Dec 23 16:39:05 <bitnumus> prpplague, how high is that?
Dec 23 16:39:25 <bitnumus> i can imagine a product that could be 1mm thick and maybe do this job, or some connectors that i could tap off the pins with
Dec 23 16:39:28 <bitnumus> but havent been able to find it
Dec 23 16:39:59 <prpplague> bitnumus: ok, so are trying to be as thin as possible?
Dec 23 16:40:08 <thews> bitnumus: http://www.buydisplay.com/default/4-3-tft-lcd-display-module-controller-board-w-serial-spi-i2c-mcu.html
Dec 23 16:40:24 <thews> would that work out for you?
Dec 23 16:40:41 <bitnumus> prpplague, as if it wasnt there ideally :D but so i can still access the pins easily, so maybe some side connection point not inside the BBB dimensions would be easiest
Dec 23 16:40:59 <thews> comes with demo code
Dec 23 16:41:00 <thews> http://www.buydisplay.com/download/democode/ER-TFTM043-3_I2C_DemoCode.txt
Dec 23 16:42:08 <thews> then you only use 2 pins
Dec 23 16:42:12 <prpplague> bitnumus: http://boardzoo.com/index.php/new-products/extended-proto-cape.html
Dec 23 16:42:22 <bitnumus> thews, i guess the driver is the main issue, what i found with RPI was a bunch of screen that have been tested and had drivers written specially for the pi, i'd be worried this screen just wouldnt work
Dec 23 16:42:23 <prpplague> bitnumus: just put that in between the lcd cape and the black
Dec 23 16:42:44 <prpplague> bitnumus: it'll work fine, there is no "driver" for it
Dec 23 16:42:45 <Guest90405> !Hola! I have BeagleBone Black, but it's revision is: B4... what does it mean? I can find only A* revisions on site...
Dec 23 16:42:49 <prpplague> bitnumus: all userspace
Dec 23 16:43:01 <thews> bitnumus: it's very easy to change RPi code to BBB,  normally just a different bus number and address
Dec 23 16:43:46 <thews> the popularity of the RPi helps me a lot on finding code to manipulate
Dec 23 16:43:46 <bitnumus> prpplague, i assume that has pins on the underside, so would add another 5mm maybe ?
Dec 23 16:44:10 <prpplague> bitnumus: yea about that
Dec 23 16:45:14 <prpplague> bitnumus: you can only do so much with using off the shelf combinations, if you really are that concerned about the height, best to just design your on cape with the features you need
Dec 23 16:45:26 <bitnumus> hmm, i assume this header pin block is always needed to get a proper connection ?
Dec 23 16:45:34 <thews> any pins not used by the LCD cape you could just snip off or desolder and put a 90 pin sandwiched between if you wanted the space
Dec 23 16:45:43 <bitnumus> prpplague, yea i wish i had the funds atm :D thats for another stage
Dec 23 16:46:01 <thews> the headers are just 0.1" females, super cheap and easy to source
Dec 23 16:46:29 <bitnumus> This extender board is probably not a horrific solution, just need to find a $5 version :D
Dec 23 16:46:41 <thews> not going to find anything for $5
Dec 23 16:46:54 <bitnumus> the cape i have runs off circuitco's drivers for the LCD4, so its plug and play
Dec 23 16:47:13 <bitnumus> this is 1/3 the price of the whole BBB, you sure ?
Dec 23 16:47:15 <thews> I buy lots of hardware parts in bulk and could probably build one for less than $5, but it'd take me an hour or more
Dec 23 16:47:35 <thews> and there's no way I could buy just the parts I needed and come out under $5
Dec 23 16:47:44 <thews> probably not under $15
Dec 23 16:48:00 <bitnumus> for sure, but there is always china right :)
Dec 23 16:48:05 <thews> nope
Dec 23 16:48:25 <thews> china mass produces stuff they can sell in bulk
Dec 23 16:49:00 <thews> BBB custom capes aren't a big market
Dec 23 16:49:10 <bitnumus> well already found it for $8  http://www.mcmelectronics.com/product/ADAFRUIT-INDUSTRIES-572-/83-14776
Dec 23 16:49:41 <bitnumus> not the same i know, but still
Dec 23 16:50:14 <prpplague> bitnumus: please note, they aren't "circuitco's drivers" they are mainline kernel drivers
Dec 23 16:50:55 <thews> the above won't let you stack a cape
Dec 23 16:51:00 <bitnumus> prpplague, i read that on the manufactures website, and thats why it doesnt work in ubuntu but only angstrom
Dec 23 16:51:29 * prpplague shakes his head
Dec 23 16:51:53 <prpplague> bitnumus: the drivers are mainline, the "timings" are not
Dec 23 16:51:57 <thews> not a bad price http://www.mcmelectronics.com/product/83-14775?green=829C4B21-6F32-5DB3-9C33-025CD48144FD
Dec 23 16:52:13 <thews> timings are easy to setup if you have the specs
Dec 23 16:52:20 <N2TOH> I clicked on that link and my machine crashed
Dec 23 16:52:39 <bitnumus> thews, you see on that link, one of the images there is a gap where you can see all of the pins
Dec 23 16:52:48 <bitnumus> are there any connectors out there that can tap onto that space?
Dec 23 16:53:02 <bitnumus> i have similar 2mm gap on the cape i have
Dec 23 16:53:23 <thews> bitnumus: sure,  you could solder onto it, or use ic hooks
Dec 23 16:53:25 * prpplague shakes his head in amazement
Dec 23 16:53:41 <bitnumus> solder isn't an option right now, what are IC hooks?
Dec 23 16:53:52 <N2TOH> test clips
Dec 23 16:54:09 <thews> https://www.google.com/search?q=ic+hooks&tbm=isch
Dec 23 16:54:22 <N2TOH> http://www.mcmelectronics.com/product/201-018
Dec 23 16:55:00 <bitnumus> little bulky i guess
Dec 23 16:55:06 <thews> no kidding
Dec 23 16:55:13 <prpplague> bitnumus: hehe if soldering isn't an option, how are you going to use the cheap prototype board when comes unassembled?
Dec 23 16:55:15 <thews> I don't know how solder isn't an option :S
Dec 23 16:55:17 <bitnumus> i was thinking of some squared lug for header pins
Dec 23 16:55:22 <thews> yeah
Dec 23 16:55:32 <thews> there's no way you're going to get anything done without solder
Dec 23 16:55:33 <bitnumus> that doesnt exist ? :P
Dec 23 16:56:06 <bitnumus> i'm messing around with a few different things i dont want to keep desoldering and soldering thing right now thats all :)
Dec 23 16:56:17 <thews> shouldn't have to tap into the pins often
Dec 23 16:56:31 <bitnumus> ie a keypad, and a custom one, i'm changing/messing with different pins all the time
Dec 23 16:56:32 <thews> and if you did you could solder some 30 gauge wires onto several pins and reuse them
Dec 23 16:56:47 <thews> why would you use multiple pins for a keypad?
Dec 23 16:56:53 * prpplague goes back to work and lets thews handle this
Dec 23 16:57:10 <bitnumus> i dont have a fixed list of parts yet is the point
Dec 23 16:57:27 <bitnumus> we've already changed main board 3 times, and 3 different screens, 2 keypads and soon to be another new keypad
Dec 23 16:57:59 <thews> analog keypad
Dec 23 16:58:06 <bitnumus> yes atm 4x4 keypad
Dec 23 16:58:15 <thews> convert it to analog
Dec 23 16:58:19 <thews> do away with using lots of pins
Dec 23 16:58:51 <thews> or use i2c
Dec 23 16:58:52 <bitnumus> o, i'm fully aware there are 100 things i'm doing wrong, or could do better
Dec 23 16:58:57 <thews> I'm fond of i2c
Dec 23 16:59:03 <bitnumus> i don't know how to do a lot tbh :)
Dec 23 16:59:17 <thews> sounds like you need to slow down and do some research
Dec 23 16:59:23 <bitnumus> no time for that!
Dec 23 16:59:25 <thews> maybe do some other projects
Dec 23 16:59:26 <bitnumus> lol
Dec 23 16:59:53 <bitnumus> nope, if i can't do it, i'll outsource it, hence my PM
Dec 23 17:00:24 <thews> outsourcing is terrible :S
Dec 23 17:00:38 <thews> as far as design
Dec 23 17:03:31 <thews> http://learn.adafruit.com/adafruit-trellis-diy-open-source-led-keypad  that looks pretty cool
Dec 23 17:04:07 <thews> it'd be cool to have some ws2812 buttons for a keypad
Dec 23 17:04:24 <thews> I can think of some cool uses for that
Dec 23 17:15:24 <mdp> thews, are you polling the w1 bus at a high rate?
Dec 23 17:16:23 <thews> mdp: I'm not directly, but the underlying onewire system might be
Dec 23 17:17:11 <mdp> well, the read byte stuff does a bunch of read bits if you are using the w1 gpio driver
Dec 23 17:17:14 <thews> the dallas one-wire driver is preinstalled
Dec 23 17:17:20 <mdp> if you are on BBB, this is the case
Dec 23 17:17:22 <thews> so I'm not sure what all it's doing
Dec 23 17:17:26 <mdp> BBB?
Dec 23 17:17:28 <thews> yep
Dec 23 17:17:32 <mdp> it's bitbanging
Dec 23 17:17:33 <thews> debian
Dec 23 17:17:43 <thews> I see
Dec 23 17:17:43 <mdp> complete with busy waits to manage the timing
Dec 23 17:17:54 <mdp> so that's not surprising to see some load from it
Dec 23 17:18:01 <thews> it is using w1 as a device
Dec 23 17:18:21 <mdp> it's one of the few things that am335x really missed out on..no h/w one-wire ip
Dec 23 17:18:23 <thews> I spaced out on that
Dec 23 17:18:40 <mdp> either way, you are using the w1-gpio driver..master or slave
Dec 23 17:18:55 <thews> yeah
Dec 23 17:19:03 <mdp> so it needs to sample non-stop on the wire looking for protocol
Dec 23 17:19:17 <mdp> anyway, it's expected
Dec 23 17:19:18 <thews> I'm pretty new to working with the hardware at this level with an OS
Dec 23 17:19:27 <thews> so I wasn't sure what to expect
Dec 23 17:19:40 <mdp> sounds like you are doing fine..just didn't want you to be alarmed by that load
Dec 23 17:20:18 <thews> changing from ruby to python really made the best difference so far on load
Dec 23 17:20:47 <thews> I might eventually write stuff in C++, but for now, definitely not
Dec 23 17:20:49 <mdp> are you using the w1 slave sysfs interface?
Dec 23 17:20:52 <thews> too much time
Dec 23 17:20:57 <thews> mdp: yes
Dec 23 17:21:25 <thews> just reading it and cutting out the parts I don't need
Dec 23 17:22:15 <thews> I've never tried to formally learn python, but I've never had problems programming in it
Dec 23 17:22:20 <thews> it feels like a mixture of a lot of languages
Dec 23 17:55:11 <bitnumus> hi again, i have a little wifi dongle that i can't see to detect plugged into BBB, works fine on a desktop. i've checked lsusb and there is only one entry, and dmesg also doesnt show anything. any ideas?
Dec 23 18:00:16 <SyNko> bitnumus you need to attach it in a usb powered hub IMHO
Dec 23 18:00:59 <bitnumus> SyNko, yea, just did that and it works, but why would the same PSU thats supplying the USB hub not be sufficient power if connected direct to the BBB ?
Dec 23 18:01:10 <bitnumus> the single USB port on the BBB doesn't get enough power?
Dec 23 18:01:42 <thews> prpplague: I think I'm done with this  http://elinux.org/BeagleBone/I2CLCDDemo
Dec 23 18:01:56 <SyNko> nope, the BBB use only 5 v so if you need another 5v usb you need more power
Dec 23 18:02:54 <thews> bitnumus: most likely you're using a realtek 8192 chip?
Dec 23 18:03:34 <bitnumus> RT5370
Dec 23 18:03:50 <SyNko> it's bugged
Dec 23 18:04:46 <thews> bitnumus: what is the result from `ls /lib/firmware/rtlwifi/`
Dec 23 18:05:36 <bitnumus> a few, rtl8192cfw.bin is there
Dec 23 18:05:49 <thews> I think that's the only driver it uses
Dec 23 18:05:58 <thews> I had to build the drivers
Dec 23 18:06:08 <thews> and blacklist those
Dec 23 18:06:57 <thews> http://wiesel.ece.utah.edu/redmine/projects/hacks/wiki/BeagleBone_Black_AP
Dec 23 18:07:24 <thews> google for beaglebone black 8192 modprobe blacklist
Dec 23 18:07:30 <thews> there's lots and lots of examples
Dec 23 18:07:38 <thews> but I have to use a powered usb hub as well
Dec 23 18:08:15 <bitnumus> so, its a driver issue on the BBB not a power problem ?
Dec 23 18:08:44 <SyNko> both
Dec 23 18:08:51 <SyNko> IMHO
Dec 23 18:08:57 <bitnumus> afaik voltage has nothing to do with it
Dec 23 18:09:27 <bitnumus> its current that gets used up right? so a more powerful PSU ie 3A should be able to power this little thing
Dec 23 18:10:12 <thews> bitnumus: voltage means nothing by itself
Dec 23 18:10:29 <thews> I imagine if you measured the voltage once it's drawing power, it's going below 5v
Dec 23 18:10:41 <thews> because not enough amperage is available
Dec 23 18:11:09 <thews> the BBBs usb does not supply much current
Dec 23 18:11:22 <bitnumus> <thews> the BBBs usb does not supply much current  <   this is what i think the problem is
Dec 23 18:11:31 <bitnumus> and seems shitty seeing as this works on RPI
Dec 23 18:11:55 <SyNko> shitty or not, that's it
Dec 23 18:12:24 <bitnumus> SyNko, no thanks to your random comments we've only just now established thats the likley cause
Dec 23 18:12:29 <bitnumus> thews, thanks again
Dec 23 18:12:42 <thews> RPI's design is quite a bit different
Dec 23 18:13:06 <SyNko> :P
Dec 23 18:13:40 <SyNko> RPI < BBB
Dec 23 18:13:58 <bitnumus> not in the USB power department :)
Dec 23 18:14:20 <SyNko> is the same
Dec 23 18:14:25 <thews> BBB is designed for devkit modularity
Dec 23 18:14:32 <SyNko> a gprs modem dont works both
Dec 23 18:14:37 <SyNko> directly attacched
Dec 23 18:14:39 <thews> RPI is designed as a low budget low power workstation
Dec 23 18:19:02 <KotH> thews: little correction here: the BBB does not provide power to the USB port
Dec 23 18:19:10 <KotH> thews: all that power comes directly from the PSU
Dec 23 18:19:22 <KotH> thews: if the PSU is weak, there is nothing the BBB can do about it
Dec 23 18:19:57 <thews> KotH: so no USB power delivery negotiation ?
Dec 23 18:20:26 <KotH> thews: do you know any device that does usb power delivery negotiation?
Dec 23 18:20:34 <bitnumus> KotH, i have a 3A PSU, so if what you are saying is correct it should be working
Dec 23 18:20:43 <KotH> bitnumus: not necessarily
Dec 23 18:20:49 <thews> KotH: yes,  the FTDI chips
Dec 23 18:21:16 <KotH> bitnumus: your psu can be deliver 3A, but what about load changes? can it react quickly enough to a load change from 100mA to 2A ?
Dec 23 18:21:19 <KotH> thews: nope
Dec 23 18:21:46 <bitnumus> KotH, its the same PSU thats supplying the USB hub that the same wifi chip works fine on.
Dec 23 18:21:56 <thews> KotH: http://www.usb.org/developers/powerdelivery/
Dec 23 18:22:16 <KotH> thews: all usb devices have a device descriptor table entry telling the host what amount power they need. the host either acknowledges this or not. but the host itself does not negotiate any power consumption
Dec 23 18:22:25 <KotH> thews: it just passes the 5V from the PSU on
Dec 23 18:22:34 <KotH> thews: i know the USB standards
Dec 23 18:24:35 <thews> KotH: I can hook up a 20 amp 5v rail to the BBB but still can't get enough current from USB for my wifi dongle
Dec 23 18:24:58 <thews> but hook it up to a powered hub with 3 amps, and have no problems
Dec 23 18:25:56 <bitnumus> its quite frustrating, i bought this tiny little dongle not expecting to need a bloody usb hub to run it :D
Dec 23 18:27:03 <thews> might be that the USB host on the BBB lacks negotiation for the wifi dongle to allow itself to draw enough power, but whatever it is, it doesn't work
Dec 23 18:29:17 <bitnumus> trying to find the BBB's usb port max amperage, i'm reading 100mA ?
Dec 23 18:29:32 <bitnumus> The port can only supply 100mA, so a powered hub may be necessary for power-hungry keyboards and mice.
Dec 23 18:29:41 <bitnumus> well thats just rubbish :(
Dec 23 18:30:13 <agmlego> Feel free to take the board files and make your own with different limits.
Dec 23 18:30:20 <agmlego> The bone is open-source hardware.
Dec 23 18:36:05 <bitnumus> thats not a new genre of reply to when something doesn't work how it probably should you know
Dec 23 18:36:26 <bitnumus> 'make your own then'
Dec 23 18:38:36 <thews> if you're going into production with something you're most likely going to be making your own anyhow
Dec 23 18:39:28 <bitnumus> thews, seems you were right regarding the supply to the USB host  http://www.ti.com/product/tps2051b
Dec 23 18:40:07 <bitnumus> page 4 of this  https://github.com/CircuitCo/BeagleBone-Black/blob/master/BBB_SCH.pdf?raw=true
Dec 23 18:45:48 <thews> it's definitely limited somehow
Dec 23 18:52:04 <bitnumus> wonder how much current my chip needs, i can't find anything yet to tell me
Dec 23 18:52:11 <bitnumus> 500mA seems enough
Dec 23 19:13:29 <drkfdr> I've acquired a beagleboard-xm, it might be half broken. plugging in 5V adapter turns on the overvoltage LED. but powering via USB works. well.. JTAG works. haven't tested anything else
Dec 23 19:16:14 <thews> drkfdr: test the 5v adapter?
Dec 23 19:16:59 <drkfdr> 5.15V... less than 5.8V
Dec 23 19:17:32 <thews> drkfdr: is it a switching powersupply?
Dec 23 19:17:44 <drkfdr> yes
Dec 23 19:18:14 <thews> I'd check out the schematics for the overvoltage light / protection
Dec 23 19:18:26 <thews> might be something you can fix
Dec 23 19:18:44 <drkfdr> I'd like to check if the rest works first
Dec 23 19:18:53 <drkfdr> using USB supply
Dec 23 19:32:57 <brents> Has anyone used the segger flasher on the jtag interface of the bbb?
Dec 23 19:44:58 * _av500_ has not
Dec 23 19:45:11 <_av500_> what for?
Dec 23 19:46:38 <thews> http://lcdproc.org/  terrible design
Dec 23 20:14:08 <pdp7_> cute https://plus.google.com/101339419642360856354/posts/gWoBPaGtz58
Dec 23 20:15:18 <pdp7> hmm what's something interesting to display on a LED ticker?

Dec 23 20:15:38 <pdp7> i could leave it running with some type of feed
Dec 23 20:18:19 <prpplague> pdp7: you can keep track of the number of lies and the text of the lies that stream out of the obama administration
Dec 23 20:25:47 <N2TOH> prpplague, computers can't count that high
Dec 23 20:26:57 <thews> pdp7: what led drivers?
Dec 23 20:27:16 <thews> nvm
Dec 23 20:31:11 <thews> pdp7: you should make some animations between the text  http://www.youtube.com/watch?feature=player_embedded&v=qztpi-BVkqE
Dec 23 21:03:32 <ZiNC> Hey.
Dec 23 21:05:17 <paul> i want to try and build a drone that uses mobile network. any recpomendations on OS?
Dec 23 21:05:45 <ZiNC> Is the new Black stock expected to be all A6A?
Dec 23 21:06:31 <ZiNC> paul: I can't say for sure, but probably unless you have a reason to change, sticking with the most common Linux-based would be the easiest.
Dec 23 21:07:08 <thews> paul: OS shouldn't really be a factor, but for embedded systems you're basically going to be linux only, you can go without OS though
Dec 23 21:07:56 <paul> its linux good for conecting up to 3g/4g network via donfler?
Dec 23 21:08:06 <paul> dongle
Dec 23 21:08:47 <ZiNC> And, any reason not to get Black from Seeed Studio?
Dec 23 21:09:57 <ZiNC> paul: It's not like you have many stock/supported OSes to choose from.
Dec 23 21:10:30 <ZiNC> I never looked, but I suppose there are existing libraries for that.
Dec 23 21:10:30 <thews> paul  http://www.timzaman.nl/?p=1247
Dec 23 21:15:56 <dhamilt9> Hey all!  I'm trying to send some data over UART1 in the latest version of Angstrom and I'm having some trouble.  I've already loaded UART1 into the slots file, but I'm not quite sure how to procede from here
Dec 23 21:16:13 <dhamilt9> I'm pretty sure I have to do something with one of the tty files, but I'm not sure what
Dec 23 21:16:13 <dhamilt9> cd
Dec 23 21:16:31 <dhamilt9> oops, that wasn't the terminal :P
Dec 23 21:17:00 <paul> thanks for that zinc
Dec 23 21:17:37 <ZiNC> You mean thews? :)
Dec 23 22:00:21 <ds2> prpplague: how do you afford such a large hosting site for such a feed?!
Dec 23 22:07:29 <prpplague> ds2: ??
Dec 23 22:09:03 <prpplague> ds2: what are you referring to?
Dec 23 22:09:09 <ds2> Re: the list of lies
Dec 23 22:09:22 <ds2> more practical to maintain a list of truths
Dec 23 22:09:40 <prpplague> ds2: ahh indeed
Dec 23 22:12:52 <k4jcw> Good localtime. I have a couple of BBBs that I want to update to Debian. On the eLinux page, there are two options, using the Flasher, and raw sdImage. However, the page doesn't help those of us who don't live full-time in this world as to which we should pick, and why. What are the differences between the two methods, please?
Dec 23 22:20:13 <myself> It's always morning: http://www.total-knowledge.com/~ilya/mips/ugt.html
Dec 23 22:20:43 <myself> (and I don't know anything about your questoin, I just lurk here.)
Dec 23 22:22:46 <k4jcw> Heh
Dec 23 22:23:19 <myself> (Last sentence of that page wins something. I'm not sure what.)
Dec 23 22:31:41 <k4jcw> So why do you lurk in this particular channel?
Dec 23 22:41:12 <ZiNC> Same as everyone else I'd assume.
Dec 23 22:48:03 <k4jcw> Definitely gotta change the LED resistors on these BBBs. Darn things are blinding :)
Dec 23 22:48:48 <flughafen> k4jcw: i just got my bbb also and they are hypnotic, but also really  blinding
Dec 23 22:50:15 <k4jcw> They toned them down at some revision level, IIRC. Mine are A5A. I have a habit of buying toys and then either taking forever to get around to them, or forgetting about them completely. I have a bin full of eval and development boards.
Dec 23 22:51:43 <flughafen> I have an a6
Dec 23 22:52:03 <flughafen> k4jcw: i am the same way with whatever youtube videos Im watching this week
Dec 23 23:25:46 <djlewis> i dont like bright blue LED's
Dec 23 23:30:12 <N2TOH> nor do I
Dec 23 23:32:09 <pdp7> thews: the LED matrix is the i2c 8x8 matrix from adafruit
Dec 23 23:32:31 <pdp7> thews:
Dec 23 23:32:36 <pdp7> thews: http://learn.adafruit.com/adafruit-led-backpack/
Dec 23 23:32:38 <thews> :D
Dec 23 23:32:39 <thews> yeah
Dec 23 23:32:45 <thews> I dug into it earlier
Dec 23 23:32:48 <pdp7> cool
Dec 23 23:33:06 <thews> pdp7: you should put some animations after so much ticker
Dec 23 23:33:07 <thews> http://www.youtube.com/watch?feature=player_embedded&v=qztpi-BVkqE
Dec 23 23:33:07 <pdp7> nice thing is that adafruit's python library written for Pi works on the BBB
Dec 23 23:33:23 <thews> pdp7: so far almost everything written for anything Pi works on the BBB
Dec 23 23:33:29 <thews> just have to change bus number and addresses
Dec 23 23:33:52 <pdp7> oh, yeah, i love the eye and mouth animation
Dec 23 23:34:28 <pdp7> i guess i should have opencv track a face and then make the eyes point in the direction
Dec 23 23:35:23 <thews> you could definitely creep some people out with that :D
Dec 23 23:36:24 <thews> pdp7: if you wanted to add a more static LCD  http://elinux.org/BeagleBone/I2CLCDDemo   I spent some time on sunday making some parts I had for arduino laying around work for the BBB
Dec 24 01:46:19 <Tenkawa> greetings all
