    Gixxer, I built this circuit some years ago. There are 2 such circuits. Each has a pwm channel connected to the "F" terminal and a couple of direction bits associated with it. The reason for 2 direction bits? They set the output to either battery or to ground state. for braking. This circuit is used with a 16F876 which has 2 pwm circuits available. The completed circuit runs 2 motors, forward and reverse with 10 bit pwm values.
