# Adapted from Arduino 0011 Makefile by M J Oldfield | |

# Original Arduino adaptation by mellis, eighthave, oli.keller | |
# | |
# 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 | |
# Arduino prior to upload | |
# | |
# 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 | |
# | |
# | |
