    How to measure the duration of PWM

    user_77989180

      Hey everyone,

         

      I know that there are lot of topic about it, but I didn't find a good one which works. I would like to measure the signal PWM from a receiver R/C. The high pulse duration is between 1ms-2ms with a frequency of 60Hz

         

      I try to use a timer but I don't achieve to get a good value.

         

      I put a timer in UDB but I don't understand what should I use.

         

      I want to start the timer when I have a rising edge, and go to an interrupt when I have a falling edge, after in my interrup I read the timer, obtain the duration and reset the timer

         

      But there are too much pins and I don't know what to choose and connect:

         

         

       

         

      Thank you
