High frequency PWM by SW

Hi All,

Based on STM32F072, how can I generate high-frequency PWM(41.6KHz) by software GPIO mode?

And moreover for read, how to do PWM input by software? is it possible to capture such high-frequency PWM input?

Thanks.

Do you want to generate or read a PWM signal?

Hi Bertrand,

PWM generate and read both two are all needed.

Any idea? if system-clock of STM32F072 is 48MHz.

Thanks.
