Please use the new major release Portenta_H7_PWM Releases v2.0.0, with completely new code to fix PWM output issue you mentioned.

Releases v2.0.0

  1. Completely new code to fix no PWM output issue. Check No PWM-Output signals #1
  2. To permit start, stop, change and restore the settings of any PWM channel on-the-fly

Debug Terminal Output Samples

1. PWM_Multi on PORTENTA_H7_M7

The following is the sample terminal output when running example PWM_Multi on Portenta_H7 to demonstrate how to start multiple PWM channels, then stop, change, restore the PWM settings on-the-fly.
