 | |
|  *  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
 | |
|  *  actions can be taken.
 | |
|  *
 | |
|  *  If the \c BOARD value is set to \c BOARD_USER, this will include the \c /Board/Buttons.h file in the user project
 | |
|  *  directory. Otherwise, it will include the appropriate built-in board driver header file.

 | |
|  *
 | |
|  *  \code
 | |
|  *      // Initialize the button driver before first use
 | |
|  *      Buttons_Init();
 | |
|  *
 | |
|  *      printf("Waiting for button press...\r\n");

|  *      uint8_t ButtonPress;
 | |
|  *      while (!(ButtonPress = Buttons_GetStatus())) {};
 | |
|  *
 | |
|  *      // Display which button was pressed (assuming two board buttons)
 | |
|  *      printf("Button pressed: %s\r\n", (ButtonPress == BUTTONS_BUTTON1) ? "Button 1" : "Button 2");
