How to synchronise 2 PWM in STM8S003F3?

Deepak Tajanpure · ‎2021-12-23

I need 2 PWM signals each with different frequency and duty cycle. So I'm using TIM1 and TIM2 for this. But these PWMs are not synchronised. Please help me on this.

Hi!

I don't really understand what you mean with "synchronized". If you say the 2 PWMs have different frequency how do you want them to be synchronized?

synchronized means rising edge of both PWMs should match

You're assuming a lot :)

I would recommend that you carefully study how the timers work (i.e., from the STM8S003F3 datasheet and the RM0016 manual), how they receive a clock, and clearly know your expectations regarding any latency between edges. Then make experiments.
