View Source Wafer.Driver.Circuits.GPIO.Dispatcher (wafer v1.1.0)
This module implements a simple dispatcher for GPIO interrupts when using
Circuits.GPIO
.
Because the Circuit's interrupt doesn't provide an indication of whether the pin is rising or falling we store the last known pin state and use it to compare.
