Ski, if you get the 24-bit stuff, here is a what a PIC24 will do in this kind of situation:
1. Hardware PWM from 30Hz to 500KHz+.
2. Up to 16-bit duty cycle resolution at lower frequencies.
3. Up to 5 independent hardware PWM's.
4. 0% processor overhead.
5. Virtually no coding - except to set up registers.
All this from a single $2, 28-pin device.![]()
