  • [04:33:53] <iandow> OK, I'm closer to getting my wifi dongle to work in the production Angstrom A6A distribution. I can see my WLAN adapter under dmesg (shows up as usb 1-1), and I can see my driver under lsmod. But ifconfig still doesn't show me a wlan interface. Ideas?
  • [04:34:30] <iandow> Also, the lsusb comamnd will hang. I can't even kill the process.
  • [04:34:53] <iandow> Ideas?
  • [04:37:45] <myself> long-shot hunch, if lsusb hangs, you might have somethig hardware wrong. Just checking some assumptions: This dongle works on other machines, including other linux machines? have you tried plugging it in through a powered hub?
  • [04:38:19] <iandow> nope, I haven't done that. Worth a try.

  • [05:00:38] <iandow> According to windows, my wlan adapter uses the Realtek RTL8188CU driver. In Angstrom, I had installed linux-firmware-rt8188cu. Possibly there's a conflict there.
  • [05:00:57] <iandow> I mean I had installed linux-firmware-rtl8192cu on Angstromn
  • [05:01:10] <iandow> * opkg_install_cmd: Cannot install package linux-firmware-rtl8188cu.
  • [05:01:31] <iandow> maybe I need a different driver.

  • [10:18:53] <sam__> is that true that when hotplug event is occured kernel send uevent which is catch by udev then it load module for that device then that module create entry or register itself in sysfs and then after that using info in sysfs again udev create device node in /dev directory ?

  • [10:54:24] <LetoThe2nd> sam__: basically you're looking at the wrong use case. they depict the something gets connected - kernel detects - udev matches - loads driver case.
  • [10:54:49] <LetoThe2nd> sam__: which does not fit the "load driver - create nodes" case
  • [10:55:12] <av500> "PC load letter" case?
  • [10:55:18] <LetoThe2nd> or more precisely, the "load driver - create nodes" is what comes *after* that.

  • [16:52:45] <_av500_> you need to drive it
  • [16:52:55] <_av500_> you cant connect the light just like that
  • [16:53:06] <_av500_> you need a transistor or so as a switch
  • [16:53:18] <_av500_> the light needsw more currrent than what a GPIO pin can deliver
  • [16:53:23] <_av500_> so you have 2 tasks now:
  • [16:53:29] <IamTrying> _av500_, i am thinking like my Arduino experience

  • [17:13:30] <IamTrying> I do not get that feelings with Beagle board
  • [17:13:49] <IamTrying> When i started Arduino, it was fun and exciting cause it works in Day 1
  • [17:14:03] <IamTrying> Beagle board does not work and not friendly / not well documented
  • [17:14:25] <mistawright> you sound like you wanted a raspberry pi insteadf
  • [17:14:27] <mistawright> you sound like you wanted a raspberry pi instead
  • [17:15:03] <IamTrying> User experience is not nice for Day 1, we want to have fun in Day 1 like all works not like go and read the book has 900 pages.
  • [17:15:58] <IamTrying> Look at Go language it simply works in 1 minute. Look at Arduino its fun. It lets build something and make it more exciting. That user experience is ignored in Beagle board.
  • [17:16:15] <mistawright> IamTrying, I am getting one soon myself and have been looking at tutorials etc. I have been using linux for a while so I dont see it as being all that complicated.

  • [17:18:01] <mistawright> I would consider the beaglebone black a great product for someone that needs more functionality than the pi. I have a raspberry pi I was given for free at work and find it to be ok. The beaglebone black on the other hand is a great platform to start with
  • [17:19:25] <mistawright> the typical person wouldnt be looking at the beaglebone black. I was waiting on an arduino tre because I have been playing around with arduino's but it is literally an arduino with a beaglebone black slapped in the middle. So I am definitely getting the beaglebone black and will be excited to see how it works for my quadcopter project
  • [17:19:50] <IamTrying> mistawright, OK - but 99% users coming from Arduino or Linux or Basic language skills. Whats to write in Day 1 something which works, my experience is bad with Beagle Board. I thought the user experience with Beagle would be much more simple and more friendly (compared to PI, Arduino)
  • [17:20:07] <mistawright> IamTrying, do some basic tutorials
  • [17:20:21] <mistawright> such as controlling the leds on the device itself
  • [17:20:33] <IamTrying> mistawright, I am doing. But first impression is the best impression, i got a feelings like Beagle board is complex.
  • [17:21:21] <mistawright> You only feel that way because the beaglebone community is not as large as the arduino or pi community.
  • [17:21:57] <IamTrying> Right. mistawright, some poeple make the new comer scared which should not happen
  • [17:22:37] <IamTrying> Any way thank you mistawright nice talking to you. Are you expert or just started like me with Beagle
  • [17:22:58] <mistawright> I have been trying to order a beaglebone black for months and walked into my local radioshack and saw it on the shelves and was lucky enough to have them hold it for me. I will be trading my galaxy s3 that needs the lens replaced for a $100 dollar credit and walk out with a free beaglebone black. my raspberry pi just sits most of the time
  • [17:23:59] <IamTrying> OK - mistawright - what makes you excited on Beagle board?
  • [17:24:31] <mistawright> IamTrying, starting out. I want to build a quadcopter with a beaglebone black on board. Exploring the idea of building my own cape to make hooking up servos and esc's a breeze. I am not too scared of the programming side of things mostly the electronics portion as I have already fried an arduino nano playing around
  • [17:25:08] <mistawright> I saw an amazing video on youtube about the beaglebone black and wowee and it made me want to get the board even more
  • [17:25:33] <IamTrying> mistawright, Cool, i want to do the same thing like you.
  • [17:25:45] <IamTrying> mistawright, but why Beagle board you can do it with Arduino too
  • [17:26:56] * onoffon is now known as khem`
  • [17:27:03] <IamTrying> mistawright, 6 motor, 6 blade, better power source, IR control for all those Quadcopter Arduino is enough. Beagle board i will need to do Gstreamer, OpenGL etc
  • [17:27:09] <mistawright> IamTrying, http://www.youtube.com/watch?v=neaFAZHc8F0, I like the idea of it being linux powered. I am a gentoo linux fanatic so sitting down and tinkering doesnt bother me
  • [17:28:38] <mistawright> I am building an arduino nano powered electric ducted fan jet that should be flown this weekend. it uses apc220 rf modules for control and two arduino nano's. I will be using the same apc220 module for the beaglebone black as well.
  • [17:29:33] <Vaizki_> You want realtime for flight control

  • [17:32:00] <Vaizki_> Yea an arduino for realtime control and bbb for General purpose computing would work
  • [17:32:36] <mistawright> IamTrying, intel nuc is an x86 pc. bbb is arm soc
  • [17:32:58] <IamTrying> mistawright, well 64-bit is much better then ARM
  • [17:33:03] <IamTrying> you can do hell lot
  • [17:33:29] <IamTrying> I am running intel NUC and at the same time i am running ARM, ARM is slow
  • [17:33:37] <IamTrying> Intel NUC is fastest and can do a lot
  • [17:33:49] <Vaizki_> Eh
  • [17:34:06] <mistawright> Vaizki_, so I should be able to send serial commands to the bbb through my rf module and then have it pass those values to the arduino for control. But would it be better to directly control through the arduino and use the bbb for adjustments during flight?
  • [17:34:50] <mistawright> IamTrying, you'll get battery life out of the beaglebone black if you are going for a mobile device
  • [17:35:09] <Vaizki_> Well I'm no expert but for quad stabilization etc you are better off with a mcu or rtos than normal Linux

  • [19:36:37] <mistawright> So I have been doing some reading/research and have come across some projects that use the beaglebone black's pru for servo control. with that being said would there be any reason to use an arduino with my beaglebone black for a quadcopter?

  • [19:40:45] <Russ> mistawright, there is also specialized hardware to control servos iirc
  • [19:40:51] <Russ> (within the am335x)
  • [19:42:26] <mistawright> Russ, I wanted to control a quadcopter and was given the advice to use the arduino for control and have the black control the arduino.
  • [19:42:27] <jcw__> You're going to want to work on your power management, if you're using a BBB on a QC. They're not exactly "low power". That's why there are boards optimized for flight control.
  • [19:43:54] <mistawright> I don't mind powering the beaglebone itself from a small single cell lipo and have the motors run from there own power source.
  • [19:44:34] <jcw__> Well, sure, you can do that. But that's more weight. More weight == decreased flight time.
  • [19:45:53] <mistawright> true enough. I would assume that a 3s 2600ma lipo would be able to power a quadcopter and the beaglebone for a 15 minute flight.
  • [19:46:17] <jcw__> Not sure if there's any flight control software that runs under linux. A lot of people use boards based on some variant of an ARM-7 core, like an STM32Fxxx part.
  • [19:46:43] <jcw__> You're carrying a lot of extra weight and power budget in flying something like a BBB, rather than a dedicated controller.

  • [20:25:52] <stt_michael> firmware?
  • [20:26:19] <stt_michael> you''l need some app to manage wifi security eg iwconfig or wpa_supplicant and/or networkmanager/wicd

  • [20:41:43] <jcw__> All I know about the RTL8192CU is I tried it under 3.8.13, 3.13.0-something, I tried the kernel drivers and the source from Realtek, and no combination worked.

  • [22:23:29] <_av500_> see some of the projects that use PRU on how to access it from both sides
  • [22:23:44] <_av500_> but first check how fast you can sample the ADC at all
  • [22:25:58] <ssl_> well, the comments on this site here say it's well above 1kH, even in the 100s of kH and also mention the PRU in doing this, but then again, they don't go into detail on how it's done

  • [23:29:11] <ssl_> yes, so it is pretty fast. problem is through filesystem access i can only achive about 100-500Hz
  • [23:29:35] <ssl_> but unfortunatly, PRU programming seems to be quite complicated

  • [23:35:28] <mdp> ssl_, google iio and adc
  • [23:36:08] <mdp> if the driver is written properly and assuming it supports dma then you can sample at high frequencies and it will fill a buffer accessible from userspace efficiently
  • [23:37:05] <ssl_> that'd be great

  • [23:37:42] <mdp> iio is explicitly designed to provide a relatively efficient interface for adcs
  • [23:39:31] <ssl_> ok cool, ill look into this
  • [23:40:23] <mdp> I took a quick looks and maybe the ip doesn't support dma in a sane way..the am335x adc iio driver simply reads from the fifo in a irq worker thread..I dunno how deep the fifo is..but I assume it's designed such that you'll be able sample at a high rate
  • [23:40:56] <mdp> but I must go..happy researching ;)
  • [23:41:45] <ssl_> ok, thank you
