[beagleboard] How to access GPIO from C/C++?

It's a bit like searching for bits and pieces, but for the PWM I use this one: https://github.com/clausqr/beaglebone-cpp-PWM
It is actually a wrapper for the filesystem interface.

For the digital i/o you could checkout this one: https://github.com/majestik666/Beagle_GPIO

For both you have to set the pinmux settings to the desired modes before you start the program. I am not totally happy with this, but it works for now. If you find something better, let me know.

Looks like a very nice embedded version of hello world to me. Good work :slight_smile:
