Debounce Switch, Rev 1.0

A c++ class for de-bouncing a mechanical switch.

• The required parameters are:

  • the GPIO input pin #
  • a flag that's true if using an internal pullup resistor, or false otherwise
  • a pair of callback functions that get called when the input pin goes either low or high
  • a debounce delay in milliseconds

• The initPin() member function must be called first. It configures the input pin, and returns the inital state of
  the switch.

• The readPin(debounceDelay) member function returns the current state (de-bounced), and calls
  the appropriate callback function whenever the pin's state changes.
