Function Documentation

WDT_vect()

void WDT_vect

(

void

)

Watchdog timer interrupt handler, for examining the buttons periodically.

The Watchdog is configured to interrupt once every 16ms, to examine the IO state of the buttons, and performing the debouncing. The debouncing algorithm looks at the last five measured IO states of each button individually, to determine whether a button has finished bouncing or not. In order to see if the button is held or just pressed, a counter (seperate for each button) is incremented every time all the last five measurements are identical and if this counter reaches the value "HOLDTIME", the button are considered held. If any IO measurement is different from the last one, the counter is reset.
