/** \page Page_ConfiguringApps Configuring the Demos, Bootloaders and Projects
|
||
|
|
*
|
||
|
|
* If the target microcontroller model, architecture, clock speed, board or other settings are different from the current
|
||
|
|
* settings, they must be changed and the project recompiled from the source code before being programmed into the microcontroller.
|
||
|
|
* Most project configuration options are located in the <tt>makefile</tt> build script inside each LUFA application's folder,
|
||
|
|
* however some demo or application-specific configuration settings are located in one or more of the source files of the project.
|
||
|
|
* See each project's individual documentation for application-specific configuration values.
|
||
|
|
*
|
||
|
|
* Each project "makefile" contains all the script and configuration data required to compile each project. When opened with
|
||
|
|
* any regular basic text editor such as Notepad or WordPad (ensure that the save format is a pure ASCII text format) the
|
||
|
|
* build configuration settings may be altered.
|
||
|
|
*
|
||
|
|
* \see \ref Page_BuildSystem for information on the LUFA build system.
|
||
|
|
*
|
||
|
|
* \section Sec_AppConfigParams The Default Application Template
|
||
|
|
*
|
||
|
|
* Below is a copy of the default LUFA application makefile, which can be used as a template for each application.
|
||
|
|
*
|
||
|
|
* \verbinclude makefile_template
|
||
|
|
*
|
||
|
|
* Inside each makefile, a number of configuration variables are listed with the syntax "<VARIABLE NAME> = <VALUE>". For
|
||
|
|
* each application, the important standard variables which should be altered are:
|
||
|
|
*
|
||
|
|
* - <b>MCU</b>, the target processor model
|
||
|
|
* - <b>ARCH</b>, the target microcontroller architecture
|
||
|
|
* - <b>BOARD</b>, the target board hardware
|
||
|
|
* - <b>F_CPU</b>, the target CPU master clock frequency, after any prescaling
|
||
|
|
* - <b>F_USB</b>, the target raw input clock to the USB module of the processor
|
||
|
|
* - <b>OPTIMIZATION</b>, the level of optimization to compile with
|
||
|
|
* - <b>TARGET</b>, the name of the target output binary and other files
|
||
|
|
* - <b>SRC</b>, the list of source files to compile/assemble/link
|
||
|
|
* - <b>LUFA_PATH</b>, the path to the LUFA library core source code
|
||
|
|
* - <b>CC_FLAGS</b>, the common command line flags to pass to the C/C++ compiler, assembler and linker
|
||
|
|
* - <b>LD_FLAGS</b>, the command line flags to pass to the linker
|
||
|
|
*
|
||
|
|
* These values should be changed to reflect the build hardware.
|
||
|
|
*
|
||
|
|
* \subsection SSec_MCU The MCU Parameter
|
||
|
|
* This parameter indicates the target microcontroller model for the compiled application. This should be set to the model of the target
|
||
|
|
* microcontroller (such as the AT90USB1287, or the ATMEGA32U4), in all lower-case (e.g. "at90usb1287"). Note that not all demos support all the
|
||
|
|
* microcontroller models and architectures, as they may make use of peripherals or modes only present in some devices.
|
||
|
|
*
|
||
|
|
* For supported processor models, see \ref Page_DeviceSupport.
|
||
|
|
*
|
||
|
|
* \subsection SSec_ARCH The ARCH Parameter
|
||
|
|
* This parameter indicates the target microcontroller architecture the library is to be compiled for. Different microcontroller
|
||
|
|
* architectures require different source files to be compiled into the final binary, and so this option must be set to the correct
|
||
|
|
* architecture for the selected platform.
|
||
|
|
*
|
||
|
|
* For supported processor architectures, see \ref Page_DeviceSupport.
|
||
|
|
*
|
||
|
|
* \subsection SSec_BOARD The BOARD Parameter
|
||
|
|
* This parameter indicates the target board hardware for the compiled application. Some LUFA library drivers are board-specific,
|
||
|
|
* such as the LED driver, and the library needs to know the layout of the target board. If you are using one of the board models listed
|
||
|
|
* on the main library page, change this parameter to the board name in all UPPER-case.
|
||
|
|
*
|
||
|
|
* If you are not using any board-specific drivers in the LUFA library, or you are using a custom board layout, change this to read
|
||
|
|
* "USER" (no quotes) instead of a standard board name. If the USER board type is selected and the application makes use of one or more
|
||
|
|
* board-specific hardware drivers inside the LUFA library, then the appropriate stub drives files should be copied from the \c /CodeTemplates/DriverStubs/
|
||
|
|
* directory into a /Board/ folder inside the application directory, and the stub driver completed with the appropriate code to drive the
|
||
|
|
* custom board's hardware.
|
||
|
|
*
|
||
|
|
* For boards with built in hardware driver support within the LUFA library, see \ref Page_DeviceSupport.
|
||
|
|
*
|
||
|
|
* \subsection SSec_F_CPU The F_CPU Parameter
|
||
|
|
* This parameter indicates the target microcontroller's main CPU clock frequency, in Hz. This is used by many libraries (and applications) for
|
||
|
|
* timing related purposes, and should reflect the actual CPU speed after any prescaling or adjustments are performed.
|
||
|
|
*
|
||
|
|
* \subsection SSec_F_USB The F_USB Parameter
|
||
|
|
* This parameter indicates the raw input clock frequency to the USB module within the microcontroller in Hz. This may be very different on some platforms
|
||
|
|
* to the main CPU clock or other peripheral/bus clocks.
|
||
|
|
*
|
||
|
|
* \subsection SSec_OPTIMIZATION The OPTIMIZATION Parameter
|
||
|
|
* This parameter indicates the level of optimization to use when compiling the application. This will allow you to compile with an optimization level
|
||
|
|
* supported by GCC, from <tt>0</tt> (no optimization) to <tt>3</tt> (fastest runtime optimization) or <tt>s</tt> (smallest size).
|
||
|
|
*
|
||
|
|
* \subsection SSec_TARGET The TARGET Parameter
|
||
|
|
* This parameter indicates the application target name, which is used as the base filename for the build binary and debugging files. This will be the
|
||
|
|
* name of the output files once linked together into the final application, ready to load into the target.
|
||
|
|
*
|
||
|
|
* \subsection SSec_SRC The SRC Parameter
|
||
|
|
* This parameter indicates the source files used to compile the application, as a list of C (<tt>*.c</tt>), C++ (<tt>*.cpp</tt>) and Assembly (<tt>*.S</tt>) files. Note that
|
||
|
|
* all assembly files must end in a <b>capital</b> .S extension, as lowercase .s files are reserved for GCC intermediate files.
|
||
|
|
*
|
||
|
|
* \subsection SSec_LUFA_PATH The LUFA_PATH Parameter
|
||
|
|
* As each LUFA program requires the LUFA library source code to compile correctly, the application must know where the LUFA library is located. This
|
||
|
|
* value specifies the path to the LUFA library core. This path may be relative or absolute, however note than even under Windows based systems the
|
||
|
|
* forward-slash (/) path seperator must be used.
|
||
|
|
*
|
||
|
|
* \subsection SSec_CC_FLAGS The CC_FLAGS Parameter
|
||
|
|
* This parameter lists the compiler flags passed to the C/C++ compiler, the assembler and the linker. These are used as-is directly to GCC and thus
|
||
|
|
* must match GCC's command line options as given in the GCC manual. This variable may be used to define tokens directly on the command line, enable or
|
||
|
|
* disable warnings, adjust the target-specific tuning parameters or other options.
|
||
|
|
*
|
||
|
|
* \subsection SSec_LD_FLAGS The LD_FLAGS Parameter
|
||
|
|
* This parameter lists the linker flags passed exclusively to the linker. These are used as-is directly to GCC and thus must match GCC's command line
|
||
|
|
* linker options as given in the GCC manual. This variable may be used to create or relocate custom data sections, or enable linker specific behaviors.
