Hello, I used nucleo F303k8. I use timer1 to create PWM. When I startup the nucleo I saw 2 pulses that I dont understand why,?

Maybe consequence of particular steps you take when initializing the GPIOs and the timer? You could confirm this by single-stepping through that initialization, or by inserting delays between individual writes to registers.

Or maybe hardware problem, which causes also the noise on both signals?

Hi,

Thanks about your answer.

When put exactly the delay in the code?
