Hello, I have managed to generate PWM on pins GPB0 and GPB1, but also wanted to know if I could use GPB2 and GPB3. On checking the Mini2440Essentials.pdf manual from andahammer.com, I couldn't find exactly where these pins are located. Are we allowed access to these pins, or are they internally connected somehow? Thanks!
Accessing GPB2 and GPB3
I do have the schematic, so does that mean that I can't use them as timer output? So what exactly do these pins do as timer outputs for the audio codec?
Unless you modify the printed circuit board, ie remove the audio codec and modify some kernel driver (?) I know very little about audio codecs. Again maybe the datasheet for the codec would give clues as to what you need to apply to those two pins.
