I'm building a drone with my BBBW as its brain. I have my remote control for it mostly coded in VB.NET. Basically what it does is it runs the BBBW on the drone in hotspot mode and it just synchs the stacks in my tablet with the BBBW and I send UDP packets via winsock with raw "joystick"

[beagleboard] VAX

Does anyone else just sit there with several PUTTY windows open and just watch that blinking blue light on their BBBW and just use their imagination that they are actually connected to the ole VAX at their old alma matter? It is a really nice little UN*X host right out of the box...I still

[beagleboard] Re: Of SPI and such

The answer I was looking for. Thank you much Graham. A yes...this is good as now I have control of my BBB UARTS from C (and thus python, etc. etc.) My next question might be an elaboration on how to access the GPIO/SPI/I2C/CAN/ADC however I have the magic key to BBB because I'm lazy and I can

[beagleboard] Re: tpa81(sensor temperatur)

You are using I2C to read a thermistor? What are you building an atom smasher lol? Switch your I2C to ADC and find a PDF of a themistor-to-voltage network of discretes and just read the ADC. My God man. :D On Tuesday, November 15, 2016 at 10:35:27 PM UTC-7, zaenal abidin wrote: > > tomorrow i

Re: [beagleboard] Running .exe file after boot

idk about the whole *.exe thing. I've found programming ANSI C that its nice to be able to port my MinGW code directly to GCC without changing my build shell scripts (*blushes* well my make files I mean). Hense a lot of my bins on my UN*X have the exe extension. Seems to work...alignment

[beagleboard] Re: Of SPI and such

Thank you for the quick and informative reply, Graham. So ttyOx IS the UART abstraction that is used by UN*X typically? So I should just be able to fopen (speaking C) /dev/ttyO1 and have read write stream access to the TX and RX pins of UART1, assuming of course I've setup the "overlays"

I would take your IT manager or sys admin out to lunch to Appleby's or Olive Garden and get to know him/her. This is a human issue not a technical one IMO. On Wednesday, January 4, 2017 at 5:44:19 PM UTC-7, Jared McIntyre wrote: > > The Window's drivers haven't been install-able without turning

[beagleboard] Re: PRU FAQ 2013-05-15

Still I am a fan of my little K150 PIC programmer. I wish I could say that I soldered it myself however I pussed out this time and got a nice little jobby from Hong Kong or somewhere. Cased it myself. I can even carry it with me if I wanted to and its USB cable is just the right length. My

[beagleboard] Re: PRU FAQ 2013-05-15

This is gold, Jason. Thank you so much for sharing this with us. I personal was wondering what a lot of this stuff was. Have to admit that I was somewhat unclear as to quite a few of these concepts, but I was especially encouraged when I read the term "industrial". It is good to know we have

[beagleboard] Web Cams and UN*X

I have a nice little environmentally-sealed Emerson camera ($30) that makes a spectacular web cam I've found. Is there a library linkable (or otherwise) with GCC whereby I can capture its USB output and manipulate it programatically. I would also want to compress it to drive in MPEG or MP4

[beagleboard] Re: Of SPI and such

Furthermore, how about putting a byte after the address byte with the length of the "frame" (and I use this term loosely) using the BBB as master (for collision avoidance, I mean) with each MCU only speaking when spoken too? Just thinking out loud lol. On Monday, January 30, 2017 at 5:55:06 AM

[beagleboard] Re: Clock frequency for i2c1

As I understand it, I2C can be used for high-speed communication, so as fast as you can realistically pull that clock line is how fast you can go. Hense the clock line. I would look at it holistically. The BBB can probably really reef on that clock line (1 Ghz processor...kernel aside) so I'd
