Hello,
I am using STM32L052K6T6 with a passive buzzer is connected to PA6. Idea was to use TIM22_CH1 as PWM output to feed the buzzer. However when I get to configure PWM on this port, only relevant looking option is "PWM Generation No Output" and indeed the pin does not seem to be outputting any PWM waveform.
I might be misunderstanding something, what does PWM Generation No Output means ? I checked the Datasheet several times, and there is no difference on specs between this channel and others. What does it mean a pin being assigned to PWM but not outputting ?
Is there a way for me to get PWM output from this pin (aside from bouncing the pin manually on every timer interrupt) ?
Many thanks,
Ali
