# LUFA GCC Compiler Buildsystem Makefile Module.
|
|
# -----------------------------------------------------------------------------
|
|
# DESCRIPTION:
|
|
# Provides a set of targets to build a C, C++ and/or Assembly application
|
|
# via the AVR-GCC compiler.
|
|
# -----------------------------------------------------------------------------
|
|
# TARGETS:
|
|
#
|
|
# size - List built application size
|
|
# symbol-sizes - Print application symbols from the binary ELF
|
|
# file as a list sorted by size in bytes
|
|
# check-source - Print a list of SRC source files that cannot
|
|
# be found
|
|
# all - Build application and list size
|
|
# lib - Build and archive source files into a library
|
|
# elf - Build application ELF debug object file
|
|
# hex - Build application HEX object files
|
|
# lss - Build application LSS assembly listing file
|
|
# clean - Remove all project intermediatary and binary
|
|
# output files
|
|
# mostlyclean - Remove intermediatary output files, but
|
|
# preserve binaries
|
|
#
|
|
# MANDATORY PARAMETERS:
|
|
#
|
|
# TARGET - Application name
|
|
# ARCH - Device architecture name
|
|
# MCU - Microcontroller device model name
|
|
# SRC - List of input source files (*.c, *.cpp, *.S)
|
|
# F_USB - Speed of the input clock of the USB controller
|
|
# in Hz
|
|
# LUFA_PATH - Path to the LUFA library core
|
|
#
|
|
# OPTIONAL PARAMETERS:
|
|
#
|
|
# BOARD - LUFA board hardware
|
|
# OPTIMIZATION - Optimization level
|
|
# C_STANDARD - C Language Standard to use
|
|
# CPP_STANDARD - C++ Language Standard to use
|
|
# F_CPU - Speed of the CPU, in Hz
|
|
# C_FLAGS - Flags to pass to the C compiler only
|
|
# CPP_FLAGS - Flags to pass to the C++ compiler only
|
|
# ASM_FLAGS - Flags to pass to the assembler only
|
|
# CC_FLAGS - Common flags to pass to the C/C++ compiler and
|
|
# assembler
|
|
# LD_FLAGS - Flags to pass to the linker
|
|
# OBJDIR - Directory for the output object and dependency
|
|
# files; if equal to ".", the output files will
|
|
# be generated in the same folder as the sources
|
|
# OBJECT_FILES - Extra object files to link in to the binaries
|
|
#
|
|
# PROVIDED VARIABLES:
|
|
#
|
|
# (None)
|
|
#
|
|
# PROVIDED MACROS:
