I am working on STM32G474. I want to synchronize timer 1 and timer 2. But the frequency of timer 1 is 1 kHz whereas, timer 2 is 2 kHz. How to synchronize both the timers?

Hello @Nsg1987,

Please check AN4776 paragraph 6.1

Also there is an example in STM32Cube package following this path : Examples\TIM\TIM_CascadeSynchro,\TIM_ExtTriggerSynchro\TIM_Synchronization

and \TIM_ParallelSynchro

I hope that helps!

Thanks Sarra.

The example gave idea about the same. But facing issue when Timer2 operates at 800 Hz and Timer 3 at 100 Hz. Output of Timer 3 remains high.

Is there any way to achive this?
