+# Version 0.1 17.ii.2009 M J Oldfield
+#
+# 0.2 22.ii.2009 M J Oldfield
+# - fixes so that the Makefile actually works!
+# - support for uploading via ISP
+# - orthogonal choices of using the Arduino for
+# tools, libraries and uploading
+#
+# 0.3 21.v.2010 M J Oldfield
+# - added proper license statement
+# - added code from Philip Hands to reset

+#
+# 0.4 25.v.2010 M J Oldfield
+# - tweaked reset target on Philip Hands' advice

+#
+# STANDARD ARDUINO WORKFLOW
+#
+# Given a normal sketch directory, all you need to do is to create
+# a small Makefile which defines a few things, and then includes this one.
+#
+# For example:
+#
+# ARDUINO_DIR = /Applications/arduino-0013
+#
+# TARGET = CLItest
+# ARDUINO_LIBS = LiquidCrystal
+#
+# MCU = atmega168
+# F_CPU = 16000000
+# ARDUINO_PORT = /dev/cu.usb*
+#
+# include /usr/local/share/Arduino.mk
+#
+# Hopefully these will be self-explanatory but in case they're not:
+#
+# ARDUINO_DIR - Where the Arduino software has been unpacked
+# TARGET - The basename used for the final files. Canonically
+# this would match the .pde file, but it's not needed
+# here: you could always set it to xx if you wanted!
+# ARDUINO_LIBS - A list of any libraries used by the sketch (we assume
+# these are in $(ARDUINO_DIR)/hardware/libraries
+# MCU,F_CPU - The target processor description
+# ARDUINO_PORT - The port where the Arduino can be found (only needed
+# when uploading
+#
+# Once this file has been created the typical workflow is just
+#
+# $ make upload
+#
+# All of the object files are created in the build-cli subdirectory
+# All sources should be in the current directory and can include:
+# - at most one .pde file which will be treated as C++ after the standard
+# Arduino header and footer have been affixed.
+# - any number of .c, .cpp, .s and .h files
+#
+#
+# Besides make upload you can also
+# make - no upload
+# make clean - remove all our dependencies
+# make depends - update dependencies
+# make reset - reset the Arduino by tickling DTR on the serial port
+# make raw_upload - upload without first resetting
+#

+#
+# ARDUINO WITH OTHER TOOLS
+#
+# If the tools aren't in the Arduino distribution, then you need to
+# specify their location:
+#
+# AVR_TOOLS_PATH = /usr/bin
+# AVRDUDE_CONF = /etc/avrdude/avrdude.conf
+#
+########################################################################
+#
+# ARDUINO WITH ISP
+#
+# You need to specify some details of your ISP programmer and might
+# also need to specify the fuse values:
+#
+# ISP_PROG = -c stk500v2
+# ISP_PORT = /dev/ttyACM0
+#
+# ISP_LOCK_FUSE_PRE = 0x3f
+# ISP_LOCK_FUSE_POST = 0xcf
+# ISP_HIGH_FUSE = 0xdf
+# ISP_LOW_FUSE = 0xff
+# ISP_EXT_FUSE = 0x01
+#
+# I think the fuses here are fine for uploading to the ATmega168
+# without bootloader.
+#
+# To actually do this upload use the ispload target:
+#
+# make ispload
+#
