CE023 - PWM Frequency Dither using dsPIC SMPS DSC

This program illustrates the use of the Dithering mode of the SMPS dsPIC devices. It uses a sequential tuning of the FRC oscillator to produce a +/- 3% dither in the frequency.

About this Code Example


In this program, PWM1 and PWM2 are configured in the complementary mode
and produce constant duty cycles. The dither mode will cause the PWM
signals to jitter about the factory calibrated frequency.
