When compiling an application * which makes use of one or more board drivers located in LUFA/Drivers/Board, you must also indicate which * board hardware you are using in your project makefile. This is done by defining the BOARD macro using * the -D switch passed to the compiler, with a constant of BOARD_{Name}. For example, * -DBOARD=BOARD_USBKEY instructs the compiler to use the USBKEY board hardware drivers. * * If your application does not use any board level drivers, you can omit the definition of the BOARD * macro. However, some users may wish to write their own custom board hardware drivers which are to remain compatible * with the LUFA hardware API. To do this, the BOARD macro should be defined to the value BOARD_USER. * This indicates that the board level drivers should be located in a folder named "Board" located inside the * application's folder. * * When used, the driver stub files located in the LUFA/CodeTemplates/DriverStubs folder should be copied to * the user application's Board/ directory, and filled out to include the values and code needed to control * the custom board hardware. Once done, the existing LUFA board level APIs (accessed in the regular * LUFA/Drivers/Board/ folder) will redirect to the user board drivers, maintaining code compatibility and * allowing for a different board to be selected through the project makefile with no code changes. * * \section Sec_BoardTemplates Board Driver Templates * * The templates for each board driver are reproduced below. * * \subsection SSec_BoardTemplates_Board Template for USER * \include "DriverStubs/Board.h" * * \subsection SSec_BoardTemplates_Buttons Template for USER * \include "DriverStubs/Buttons.h" * * \subsection SSec_BoardTemplates_Dataflash Template for USER * \include "DriverStubs/Dataflash.h" * * \subsection SSec_BoardTemplates_Joystick Template for USER * \include "DriverStubs/Joystick.h" * * \subsection SSec_BoardTemplates_LEDs Template for USER * \include "DriverStubs/LEDs.h" */
