I am working with a STM32G474 and I want to use a PWM with 390kHz for a boost converter. I generate a PWM with the HRTIM WaveformOutputStart. Using WaveformOutputStop pulls the LPWM to low, but the HPWM remains on high.

Thanks a lot! It works now and both outputs end up being Low.If I want to Restart the PWM later, can I just use GPIO_MODER again or do I have to make some additional changes?

Thanks for your answer.If I start the PWM in the main, it is working fine,. But if after a short delay I change the Pins mode to GPIO Output, the PWM isn't working anymore, although in that part nothing is changed. Any clues what I might be doing wro...

I found the Null Duty cycle exception in the reference Manual, but that isn't working either. Does anyone have an example Code where that is working?

Hi, I need to stop a PWM sometimes and in these cases both the low and the high side Pin should be pulled to low. Is it possible to do that?
