Timer2 uses timer input capture mode. The input is coming from a function generator and is a block signal. It triggers the capture callback on falling edge. On the capture Callback interrupt I read in the capture compare register of Timer2 and I chan...

I generate a PWM signal on a pin going from duty cycle 0 to 100 and back to 0% to generate a sine wave using an LC Filter. When I connect the LC filter, the output is still an PWM with some spikes. C = 147µF L = 47µH f = 1,91 kHz

Timer input capture mode: DAC generation on incoming frequency from function generator.

I try to adjust the period of my timer to a certain value on the moment a button generates an interrupt.

Are there STM32 MCUs that have DAC, PWM etc channels that go up to 5V and not 3.3V? If yes which one?

STM32G431KB: I try to make a PWM signal out of my TIM1 channel. I followed this tutorial: https://controllerstech.com/pwm-in-stm32/ My PWM signal goes from 1V to 4.3V and not from 0 to 3.3V. How is this possible?
