Hello,I'm facing a problem with a master timer and slave timer on Nucleo-STM32H723ZGT6U. To better understand my issue, I will present you my project.Project presentationMy aim is to make two PWM signals like this :The red signal is named "synchro ar...

Oh my bad, I completely forgot to describe signals on the scope, sorry.The blue signal is the rising edge of synchro arch and the yellow one the rising edge of the first synchro pulse. Here, there is a delay of 20µs. For others synchro pulse it is th...

I think you're right about using the one pulse mode. It's easier to control. Also, I can start with 5-10 pulses, so it's easier to debug, then I can expand to 100 pulses.First I will try to multiply by 100 just to see ^^. Thank you for your advise 

Hello, thank you for your answer!The point you make about preload safety is interesting, I need to safe this part of my program. At the moment I don't know how to do it cleanly.For the jitter, you right. However, I don't understand why a small change...

To illustrate my new issue, I take two photos:The first one is when I sent 501µs to UART > There is a jitterThe second one is when I sent 500.0804322µs to UART >There is no jitterThe clock timer frequency is 8.33MHz, one is a perfect multiple of this...

After investigations, I succeeded to resynchronize timers.To do that, I change the slave mode from "Trigger mode" to "Reset mode". Moreover, I enabled the autoreload preload for master and slave timer, so normally random update in a cycle does not br...
