Phase shift PWM generation using etpu

vrushalitaklika — Fri, 12 May 2017 09:18:16 GMT

Hi,

I am looking for PWM generation with change in phase shift.

I tried looking at application note example AN5374, but it seems here they are updating duty cycle.

In my project I have duty cycle as constant and updating phase shift.

Please suggest a sample example of phase shift using etpu module.

Thanks

I am not sure from you description what you are trying to achieve, but maybe you could pay attention to SPWM function allowing to generate multi-channel synchronized PWM allowing to change duty cycles and phase at any time:

Hi David,

With help of SPWM can we introduce phase shift between engine A and engine B etpu channels?

Is there any api provided by etpu

Thanks
