Is this a trick question? Out of the infinite ways of bit banging and hardware, I would choose to use the PWM. On the other hand, I'll bet that there is something else going on in the device or you would be using a 12 series. The deal is to write your code with a mini-RTOS so that lots of things can happen "at once". I still would fire up the PWM and let it do its task if a square wave is all that is required. I'd still use the PWM for the sampling frequency if a more complex audio waveform is needed. Tom Mariner {Original Message removed}
