WebSingle Timer method : PWM PIC Interrupt driven timer. The key to creating a PIC PWM is to use an interrupt from one of the timers which is used as the resolution timer for the PWM period. In the example below Timer 0 is used as the resolution timer and has a frequency of 33kHz or a period of 30us. Note:This is not the PWM frequency.
