I am using TIM2 on a STM32H7 to generate interrupts - e.g. every 1 ms. Using the formulas from the documentation, Update_event = TIM_CLK/((PSC + 1)*(ARR + 1)*(RCR + 1)), solving for ARR and using RCR = 0 we getARR = 1/(Update_event * (1 + PSC) / TIM_...

That's exactly what I needed, things are working perfectly now! Amazing how quickly you could sort that out for me, thanks a lot

This does indeed seem to apply to me as I am using a Nucleo dev board.. Thanks for sharing!I am however not sure about what they mean when they speak of this 'partial workaround' - how do I change the MCO to this 25/3 MHz mode and how do I make my ST...

Hi,Thanks for the reply. I am using HSE at 8MHz through PLLCLK generating a system clock at 550 MHz and 275 MHz for the timers. Please see the attached screen shot. I have also noticed jitter in the order of 1us, which seems to me as a bit more than ...
