Elapsed time in milliseconds between two input signals.
I am using an optical reflective sensor and a Raspberry Pi using Python or C (whichever is faster) to measure RPM. So I need to measure elapsed time in milliseconds between two signals on an GPIO pin. Will appreciate help.
As for measuring how long something took in python, you can use time.time() and taking the difference of two logged values, each one taken after a input signal.
