In my application I want to use timer to turn on LED for around 300ms and simultaneously generate PWM signal of freq 2.7kHz (for buzzer) on PA10 pin. Is there any way I can achieve this?
(NOTE: I have already used TIM2 and TIM21 timers. TIM21 is also running at the same time as I trun on LED and buzzer)
No matter what configurations I set on channel 1, I always get around 400us wave as shown in screenshot below.
