/** \page Page_WritingBoardDrivers Writing LUFA Board Drivers
*
* LUFA ships with several basic pre-made board drivers, to control hardware present on the supported board
* hardware - such as Dataflash ICs, LEDs, Joysticks, or other hardware peripherals. 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"
