# WinAVR Sample makefile written by Eric B. Weddington, Jörg Wunsch, et al.
# Released to the Public Domain
# Please read the make user manual!
#
# Additional material for this makefile was submitted by:
#  Tim Henigan
#  Peter Fleury
#  Reiner Patommel
#  Sander Pool
#  Frederik Rouleau
#  Markus Pfaff
#
# Adopted to our needs for FREMO Clock by
#  Bernd Wisotzki, Martin Pischky and Stefan Seibt
#
# On command line:
#
# make all = Make software.
#
# make clean = Clean out built project files.
#
# make version = shows adapted version string from sysdef.h
#
# make coff = Convert ELF to AVR COFF (for use with AVR Studio 3.x or VMLAB).
#
# make extcoff = Convert ELF to AVR Extended COFF (for use with AVR Studio
#                4.07 or greater).
#
# make program = Download the hex file to the device, using avrdude.  Please
#                customize the avrdude settings below first!
#
# make program-flash = Download the flash hex file only
#
# make program-eeprom = Download the eeprom hex file only
#
# make program-fuses = Download the fusese only
#
# make filename.s = Just compile filename.c into the assembler code only
#
# make doxygen = run doxygen to build documentation
#
# make umlet = generate fremoclock.uxf.pdf from fremoclock.uxf
#
# To rebuild project do "make clean all".
