I've got the PIC'n up the PACE book, which does go into some PWM which has
helped a bit. The other thing is that I'm not looking to do this in
software - especially where the A/D comes in with the POT controlling the
angle of the servo. I'd like to do it without a separate A/D chip (unless
the resolution and reliability is better).
