jensdehoog 0:fd29cd85e75e 4 Due to the imperfect design of the buttons, a press on the button is registered multple times.
jensdehoog 0:fd29cd85e75e 5 The debouncer module makes sure that these false positives of the button are going to be ignored.
jensdehoog 0:fd29cd85e75e 6
jensdehoog 0:fd29cd85e75e 7 Also, this module provides a multiclick service which allows the user to press the button multiple times
jensdehoog 0:fd29cd85e75e 8 within a certain time frame. Therefore, multiple actions can be mapped to a single button.
