WebThe debounce algorithm which currently appears to be used exclusively is to "wait" a while after a keypress is initially detected, so that if the signal is merely a ghost signal i.e. of a very short interval, then no keypress event is sent e.g. to the upper layer (e.g. the USB keyboard driver). Failure to do some sort of debounce, means that a ...
