@maxgerhardt Thank you, clearing the interrupt pending bit fixed it. I got the code from a tutorial on Youtube which you can see here . Now that i watch it again, he also is clearing the interrupt pending bit. I must have looked over it. I also needed to add this line. TIM2->CR1 |= TIM_CR1_CEN;

Does the code work when compiled with a different toolchain/IDE or has the code never worked before? Also define “not working”. No outupt, wrong frequency output, …? More info needed.
