I have some questions about timer capture in the STM32. Is it possible to capture a digital signal? Like this:

Digital signal

Actually, I'd like to know how many clock ticks between rising and falling edge, in every pulse.

  • 1st situation: No info about signals frequency

Certainly, if you measure the input signal with the timer and accept the minimum time between the rising and the lowering edge as 1 clock, you can obtain the signal in STM32. If there is not a single "1" data in the signal, unfortunately the frequency of the signal you find will be lower than it should.

  • 2nd situation: If the signal frequency is known

There's no need for assumption about frequency.

I would advise you to examine document submitted from Scott Seidman
