-/** \page Page_BuildSystem The LUFA Build System

- *

- *  \section Sec_BuildSystem_Overview Overview of the LUFA Build System

- *  The LUFA build system is an attempt at making a set of re-usable, modular build make files which

- *  can be referenced in a LUFA powered project, to minimize the amount of code required in an

- *  application makefile. The system is written in GNU Make, and each module is independent of

- *  one-another.

- *

- *  For details on the prerequisites needed for Linux and Windows machines to be able to use the LUFA

- *  build system, see \ref Sec_CompilingApps_Prerequisites.

- *

- *  To use a LUFA build system module, simply add an include to your project makefile. All user projects

- *  should at a minimum include \ref Page_BuildModule_CORE for base functionality:

- *  \code

- *  include $(LUFA_PATH)/Build/lufa_core.mk

- *  \endcode

- *

- *  Once included in your project makefile, the associated build module targets will be added to your

- *  project's build makefile targets automatically. To call a build target, run <tt>make {TARGET_NAME}</tt>

- *  from the command line, substituting in the appropriate target name.

- *

- *  \see \ref Sec_ConfiguringApps_AppMakefileParams for a copy of the sample LUFA project makefile.

- *

- *  Each build module may have one or more mandatory parameters (GNU Make variables) which <i>must</i>

- *  be supplied in the project makefile for the module to work, and one or more optional parameters which

- *  may be defined and which will assume a sensible default if not.

- *

- *  \section SSec_BuildSystem_Modules Available Modules

- *

- *  The following modules are included in this LUFA release:

- *

- *  \li \subpage Page_BuildModule_ATPROGRAM - Device Programming

- *  \li \subpage Page_BuildModule_AVRDUDE - Device Programming

- *  \li \subpage Page_BuildModule_BUILD - Compiling/Assembling/Linking

- *  \li \subpage Page_BuildModule_CORE - Core Build System Functions

- *  \li \subpage Page_BuildModule_CPPCHECK - Static Code Analysis

- *  \li \subpage Page_BuildModule_DFU - Device Programming

- *  \li \subpage Page_BuildModule_DOXYGEN - Automated Source Code Documentation

- *  \li \subpage Page_BuildModule_HID - Device Programming

- *  \li \subpage Page_BuildModule_SOURCES - LUFA Module Source Code Variables

- *

- *  If you have problems building using the LUFA build system, see \subpage Page_BuildTroubleshooting for resolution steps.

-

- /** \page Page_BuildModule_BUILD The BUILD build module

- *

- *  The BUILD LUFA build system module, providing targets for the compilation,

- *  assembling and linking of an application from source code into binary files

- *  suitable for programming into a target device, using the GCC compiler.

- *

- *  To use this module in your application makefile, add the following code:

- *  \code

- *  include $(LUFA_PATH)/Build/lufa_build.mk

- *  \endcode

- *

- *  \section SSec_BuildModule_BUILD_Requirements Requirements

- *  This module requires the the architecture appropriate binaries of the GCC compiler are available in your

- *  system's <b>PATH</b> variable. The GCC compiler and associated toolchain is distributed in Atmel AVR Studio

- *  5.x and Atmel Studio 6.x installation directories, as well as in many third party distribution packages.

-/** \page Page_BuildTroubleshooting Troubleshooting Information

- *

- *  LUFA uses a lot of advanced features of the AVR-GCC compiler, linker, and surrounding binaries. This can sometimes lead to problems compiling applications if one of these

- *  features is buggy in the version of the tools used in a build environment. Missing utilities and incorrectly set makefile configuration options can also result in different

- *  errors being produced when compilation or other operations are attempted. The table below lists a set of commonly encountered errors and their resolutions.

- *

- *  <table>

+/** \page Page_BuildSystem The LUFA Build System
+ *
+ *  \section Sec_BuildSystem_Overview Overview of the LUFA Build System
+ *  The LUFA build system is an attempt at making a set of re-usable, modular build make files which
+ *  can be referenced in a LUFA powered project, to minimize the amount of code required in an
+ *  application makefile. The system is written in GNU Make, and each module is independent of
+ *  one-another.
+ *
+ *  For details on the prerequisites needed for Linux and Windows machines to be able to use the LUFA
+ *  build system, see \ref Sec_CompilingApps_Prerequisites.
+ *
+ *  To use a LUFA build system module, simply add an include to your project makefile. All user projects
+ *  should at a minimum include \ref Page_BuildModule_CORE for base functionality:
+ *  \code
+ *  include $(LUFA_PATH)/Build/lufa_core.mk
+ *  \endcode
+ *
+ *  Once included in your project makefile, the associated build module targets will be added to your
+ *  project's build makefile targets automatically. To call a build target, run <tt>make {TARGET_NAME}</tt>
+ *  from the command line, substituting in the appropriate target name.
+ *
+ *  \see \ref Sec_ConfiguringApps_AppMakefileParams for a copy of the sample LUFA project makefile.
+ *
+ *  Each build module may have one or more mandatory parameters (GNU Make variables) which <i>must</i>
+ *  be supplied in the project makefile for the module to work, and one or more optional parameters which
+ *  may be defined and which will assume a sensible default if not.
+ *
+ *  \section SSec_BuildSystem_Modules Available Modules
+ *
+ *  The following modules are included in this LUFA release:
+ *
+ *  \li \subpage Page_BuildModule_ATPROGRAM - Device Programming
+ *  \li \subpage Page_BuildModule_AVRDUDE - Device Programming
+ *  \li \subpage Page_BuildModule_BUILD - Compiling/Assembling/Linking
