PWM

[Vid Vranjek]

Hi! Does anyone now if cubieboard supports any hardware PWM on any of the GPIO pins? If so, how do I program them with ubuntu installed? If not, any alternatives how to make PWM on cubieboard. I need it mostly for controlling servos wich is a 50 Hz cycle. Thanks!!!

A10 specs show 1 (one) pwm pin, but I can't tell if we have documentation to program it.

Keep simple, stay foolish.

There is two pwm channels. And two pwm pins: PB2 (cubie have it on extension headers) and PI3 (not connected on board ?)
