This would work. Not sure if it does what you want. What it *does* do is open pin 35 for pulse input using the internal pull-up and counts width of *positive* pulses on that line, i.e. how long it has been between when whatever is connected to the pin pulled it low (as opposed to for how long it was pulled low).
