Non-blocking Switch Debounce question
Implement and test non-blocking switch de-bouncing. The programwill use the Teensy’s 8-bit timer in normal mode, with overflowinterrupt handling. You will implement a timer overflow interrupthandler which will sample the state of a designated switch atuniform intervals, and from these measurements determine if theswitch has settled into an open or closed state.
Firstly, the use of an interrupt means that de-bouncing iscarried out behind the scenes without holding up the main eventloop of a program. Secondly, the interrupt handler will be totriggered at a pre-defined uniform frequency, so that computationsin the main event loop do not affect the
