# Hey Emacs, this is a -*- makefile -*-
#
# General-purpose makefile for ATMEL XMEGA
#
# based on the
# 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
#
# Updated for XMEGA by:
# Alex Forencich
#
# On command line:
#
# make all = Make software.
#
# make clean = Clean out built project files.
#
# 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 filename.s = Just compile filename.c into the assembler code only
#
# To rebuild project do "make clean" then "make all".
