◆ powerUpButtons()

void powerUpButtons ( void )

Power up the GPIO pushbuttons.

◆ checkButtonQueue()

bool checkButtonQueue ( buttonEvt_t * evt )

Service the queue of button events that caused interrupts This only returns a single event, even if there are multiple in the queue This function may be called multiple times in a row to completely empty the queue.
