# Adapted from Arduino 0011 Makefile by M J Oldfield
16
# Original Arduino adaptation by mellis, eighthave, oli.keller
18
# Version 0.1 17.ii.2009 M J Oldfield
20
# 0.2 22.ii.2009 M J Oldfield
21
# - fixes so that the Makefile actually works!
22
# - support for uploading via ISP
23
# - orthogonal choices of using the Arduino for
24
# tools, libraries and uploading
26
# 0.3 21.v.2010 M J Oldfield
27
# - added proper license statement
28
# - added code from Philip Hands to reset
29
# Arduino prior to upload
31
# 0.4 25.v.2010 M J Oldfield
32
# - tweaked reset target on Philip Hands' advice

# STANDARD ARDUINO WORKFLOW
38
# Given a normal sketch directory, all you need to do is to create
39
# a small Makefile which defines a few things, and then includes this one.
43
# ARDUINO_DIR = /Applications/arduino-0013
46
# ARDUINO_LIBS = LiquidCrystal
50
# ARDUINO_PORT = /dev/cu.usb*
52
# include /usr/local/share/Arduino.mk
54
# Hopefully these will be self-explanatory but in case they're not:
56
# ARDUINO_DIR - Where the Arduino software has been unpacked
57
# TARGET - The basename used for the final files. Canonically
58
# this would match the .pde file, but it's not needed
59
# here: you could always set it to xx if you wanted!
60
# ARDUINO_LIBS - A list of any libraries used by the sketch (we assume
61
# these are in $(ARDUINO_DIR)/hardware/libraries
62
# MCU,F_CPU - The target processor description
63
# ARDUINO_PORT - The port where the Arduino can be found (only needed
66
# Once this file has been created the typical workflow is just
70
# All of the object files are created in the build-cli subdirectory
71
# All sources should be in the current directory and can include:
72
# - at most one .pde file which will be treated as C++ after the standard
73
# Arduino header and footer have been affixed.
74
# - any number of .c, .cpp, .s and .h files
77
# Besides make upload you can also
79
# make clean - remove all our dependencies
80
# make depends - update dependencies
81
# make reset - reset the Arduino by tickling DTR on the serial port
82
# make raw_upload - upload without first resetting

# ARDUINO WITH OTHER TOOLS
88
# If the tools aren't in the Arduino distribution, then you need to
89
# specify their location:
91
# AVR_TOOLS_PATH = /usr/bin
92
# AVRDUDE_CONF = /etc/avrdude/avrdude.conf
94
########################################################################
98
# You need to specify some details of your ISP programmer and might
99
# also need to specify the fuse values:
101
# ISP_PROG = -c stk500v2
102
# ISP_PORT = /dev/ttyACM0
104
# ISP_LOCK_FUSE_PRE = 0x3f
105
# ISP_LOCK_FUSE_POST = 0xcf
106
# ISP_HIGH_FUSE = 0xdf
107
# ISP_LOW_FUSE = 0xff
108
# ISP_EXT_FUSE = 0x01
110
# I think the fuses here are fine for uploading to the ATmega168
111
# without bootloader.
113
# To actually do this upload use the ispload target:
