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. |
