Makefile

#
# Generic and Simple GNU ARM Makefile
#
# Desinged for the gnu-arm-none-eabi tool chain
#
# Features
# - create hex file
# - create assembler listing (.dis)
#
# Limitations
# - only C-files supported
# - no automatic dependency checking (call 'make clean' if any .h files are changed)
#
# Targets:
# make
# create hex file, no upload
# make upload
# create and upload hex file
# make clean
# delete all generated files
#
# Note:
# Display list make database: make -p -f/dev/null | less
#
#================================================
# External tools
# The base directory of gcc-arm-none-eabi
# Can be empty on Ubuntu and installed gcc-arm-none-eabi
# If set, GCCBINPATH must contain a "/" at the end.
