Hi,
I'm trying to work with Interrupts, firstly on GPIO.
Is there a reference code for enabling and working with interrupts on the
AM335X? (BBB)
Thank you.

Pad control registers can only be changed in kernel space. You could write a
kernel driver or do it the right way and use device tree.

Hi, I new in BBB and linux.
I need to display on a LCD (22) a loop of a video file and the state of

How I do this?
I have tutorials of python and cloud9 programming on BBB so I think I can
manage with the firmware of pushbuttons and sensors.
python + GTK?
