#
# Arduino-1.0 Makefile 
#
# written by olikraus@gmail.com
#
# Features:
#   - boards.txt is used to derive parameters
#   - All intermediate files are put into a separate directory (TMPDIRNAME)
#   - Simple use: Copy Makefile into the same directory of the .ino file
#
# Limitations:
#   - requires UNIX environment
#   - TMPDIRNAME must be subdirectory of the current directory.
#
# Targets
# 	all		build everything
#	upload	build and upload to arduino
#	clean	remove all temporary files (includes final hex file)
#
# History
#	001	28 Apr 2010	first  release
#	002  05 Oct 2010	added 'uno'
#	003  06 Dec 2011    arduino 1.0 
#	004  11 Feb 2012     u8glib
