Have jitter in TIM1 PWM

[MTora.1]

Split from this thread.

Actually, I have jitter in TIM1 PWM. Is there any way to decrease jitter?

Hi @MTora.1 ,

please elaborate: what's your hardware, what is the primary clock source, what is the TIM1 setup exactly, how do you observe the output, what do you see there and how is it different from the expectations?

The hardware is STM32G030K8.

When the motor stops, it flicks. My first guess was a lack of capacitance of DC bus capacitor. But it was perfect. I see jitter.

This alone makes you think there is PWM jitter?

There is jitter due to using HSI, but far below anything that matters for motor control.
