    I was fighting with a 18F4550 and it's 4 multiplexed PWM's (P1-P4). I had no time to study about it. My timeless and fast solution was I just used an ordinary pwm PIC (16F628a) and a (fast) 4052 multiplexer and forgot about enhanced pwm stuff for a 1/256th microstepper unipolar stepper motor controller I made. Also used a SN754410NE bridge.

    Cheap, fast & easy...

    (The 18F4550 i left it for another USB proyect)
