The code suggested by johnwasser in the post Square wave generator and frequency meter - #3 by johnwasser works well only for low frequencies. I would like to have something like that to capture frequencies & duty cicle from 1Hz to 1MHz. Any suggestion ? Thanks

Get a Teensy LC (or Teensy 3.x) and use the appropriate PJRC Frequency Library.
