When compiling an application * which makes use of one or more board drivers located in <i>LUFA/Drivers/Board</i>, you must also indicate which * board hardware you are using in your project makefile. This is done by defining the <tt>BOARD</tt> macro using * the <tt>-D</tt> switch passed to the compiler, with a constant of <tt>BOARD_{Name}</tt>. For example, * <tt>-DBOARD=BOARD_USBKEY</tt> instructs the compiler to use the USBKEY board hardware drivers. * * If your application does not use <i>any</i> board level drivers, you can omit the definition of the <tt>BOARD</tt> * 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 <tt>BOARD</tt> macro should be defined to the value <tt>BOARD_USER</tt>. * 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 <tt>LUFA/CodeTemplates/DriverStubs</tt> folder should be copied to * the user application's <tt>Board/</tt> 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 * <tt>LUFA/Drivers/Board/</tt> 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 <Board/Board.h> * \include "DriverStubs/Board.h" * * \subsection SSec_BoardTemplates_Buttons Template for USER <Board/Buttons.h> * \include "DriverStubs/Buttons.h" * * \subsection SSec_BoardTemplates_Dataflash Template for USER <Board/Dataflash.h> * \include "DriverStubs/Dataflash.h" * * \subsection SSec_BoardTemplates_Joystick Template for USER <Board/Joystick.h> * \include "DriverStubs/Joystick.h" * * \subsection SSec_BoardTemplates_LEDs Template for USER <Board/LEDs.h> * \include "DriverStubs/LEDs.h" */
