Thread: High Frequency 16 bit PWM Dimming
picon face BY : Jim Ruxton email (remove spam text)

I got a reality check today when I thought I would try setting up a PIC for 24 KHz 16 bit PWM . I had been using 10 bit and wanted to up the resolution. After doing some calculations using something like the PIC 16F1779 with integrated 16 bit PWM , I would require a 1.6 GHz clock to achieve 16 bits at 24 kHz . Just curious what other folks would use for such an application. Highest frequency one could get using 16 bit PWM with a  32 MHz clock is about 488 Hz.
