Hello guys,

I made a mistake on the last PCB layout and atatched two different things in TIM3. I found out that the buzzer I want to use can be remapped to TIM1_CH2N because it's connected to PB0.

Unfortunately I did not get this (special) output to work.

Can anyone supply me with an as-simple-as-possible-solution for getting a rectangular wave (2kHz for a buzzer) out of TIM1_CH2N using the STM32FWlib.

regards

Christoph
