Working with ARM in BeagleBone Black

[electroRF]

Hi,
I'm working with BeagleBone Black.

I wanna practice configuring its GPIO Pins to PWM / Timer / Output pins, etc.

1. the BBB is running Linux. it is still possible to configure its IO Pins directly?
If yes, where can one read which libraries should be included in the program to be able to "name" these IO Pins?

Thank you very much.

Regards.

The BeagleBone Black looks pretty cool, I've worked with other ARM boards but not that one.
There are python libs to help with user level programs running python.

To directly configure pins you need to understand the PinMux/DeviceTree (Like PPS on PIC controllers) seen on later Linux kernels for ARM.
