This is a simple library for an interrupt based, non-blocking alternative to Arduino's pulseIn function. Since it uses interrupts to measure signals, one can read multiple signals without fear of delays in the main loop.
A pin change interrupt is used to detect when a signal is rising or falling, and the on-time of the signal is measured in microseconds. As such, this library is only suited to decode PWM-like signals, where the time of the pulse-width (on-time) determines the value of the signal.
This library depends on the PinChangeInterrupt library, so it works with standard Arduinos (Uno, Nano, Mega, etc) and the digiSpark ATTinys boards. Please see the documentation of PinChangeInterrupt to see if your board is supported.
