So if a signal is triggered and stay in active level for less than BUTTON_DETECTION_DELAY (ms), it will not be considered as button pressed.</p> <p>So depend on how long your signal be stayed in active level, you can set your BUTTON_DETECTION_DELAY accordingly to avoid glitch and noise.</p><div style="clear:both;"></div>
