Re: [beagleboard] Prevent overheating BeagleBone?

The DS18B20 is the 1-wire sensor I'm using. I knew that when I initially connected it, but have not bothered to remember that after looking at the datasheet . . .too much else going on right now. They're really easy to read from using C, and C++( one or the other ), and probably any other language

Re: [beagleboard] Prevent overheating BeagleBone?

HI Drew, I have not used a thermocouple on the beaglebone it's self. I have however used a SPI interface MAX31855, and they ramp up fairly quickly, and are reasonably accurate. We used this for a convection oven to reflow oven conversion. In testing, it seemed to work really well, but we never

[beagleboard] Phasors calculation using libpruio

I have the following C code's parts that uses tables of sins and cosins to calculate a fundamental phasor of 60 Hz electrical system using 16 samples per cycle (960 Sps): float cosins[]={1, 0.92388, 0.70711, 0.38268, 0, -0.38268, -0.70711, -0.92388, -1, -0.92388, -0.70711,

Sorry for necromancing this thread, but I've just spent a little while trying to solve this issue and the suggestions of logind.conf didn't help. I'm using Angstrom from a few years ago, and I did find the solution finally to this problem and thought I'd share : I actually had to edit the

Re: [beagleboard] Beaglebone Black won't boot sometimes

If you still want to use the same pins, you can create an extra enable pin, after everything boots up into the kernel, use gpio_request and gpio_output to enable to the (EN pin) of power supply of your motor. In this way you prevent SYSBOOT affected and other voltage flows in, to affect power up

[beagleboard] AM5718 Board

I thought some of you might be interested in a new Kickstarter project based on the AM5718, the little brother to the AM5728. This is a very unique application and one that I think has a lot of legs. Here is the link: http://kck.st/2kdOQXS Take a look! -- Gerald ger...@beagleboard.org

I'm using my Beaglebone Black to drive a DC motor and read a rotary encoder: https://github.com/justinpearson/Beaglebone-motor-from-command-line/blob/master/Images/lil-motor-setup.jpg Last night when I rebooted my BBB, it shut down but didn't reboot: None of the 4 blue LEDs lit, although the

[beagleboard] Beagleboard X15 LVDS extension board

Hi, I managed to get my first extension board working for Beagleboard X15. I wanted to be able to use some LCD panel with video out extension port (P18), this can be easily done with TI SN75LVDS83B transmitter, which I integrated into this design. I also added some GPIO on a standard pinout to

I accidentally plugged 12V instead of 5V and now, it works only if powered through USB. Wondering, if it is ok or not... Also, when i attach 5V now and if i measure voltage on the board it shows around 1.7V.. any ideas? Is it broken or not??? -- For more options, visit
