* Hardware buttons driver. This provides an easy to use driver for the hardware buttons present on many boards.
|

|
|
* It provides a way to easily configure and check the status of all the buttons on the board so that appropriate

|
||
|
|
* If the \c BOARD value is set to \c BOARD_USER, this will include the \c /Board/Buttons.h file in the user project
