Re: Phase Shift of PWM output & Faulty behaviour below 10 Hz

I spent a few hours today to assess my issue and I think for the optimize implementation I
have to write my own driver.

As a workaround for now:

Is somebody aware of how to start two MCPWM timers with a delay in between to generate the phaseshift ?

Re: Phase Shift of PWM output & Faulty behaviour below 10 Hz

Thank you for your answer.

The link to the issues was very helpful to solve the frequency problem.

Regarding the phase shift, I would highly appreciate to maintain a maximum
number of PWM outputs. Thus, a solution - if possible - using only one timer
would be awesome.

Phase Shift of PWM output & Faulty behaviour below 10 Hz

Dear users, I have been using the ESP32-WROOM 32 Devkit V1 and ESP32 IDF for many projects but now reached the point where I need some help. Usually, I am using the MCPWM unit to generate PWM. Now, I would like to phase shift two channels (A & B) with same frequencies (0 - 35 Hz) and duty cycle (50%...
