# This is a general purpose makefile for use with Arduino hardware and
31
# software. It works with the arduino-1.0 software release. To download the
32
# latest version of this makefile, visit the following website, where you can
33
# also find more information and documentation on it's use. The following text
34
# can only really be considered a reference to it's use.
36
# http://ed.am/dev/make/arduino-mk
38
# This makefile can be used as a drop-in replacement for the Arduino IDE's
39
# build system. To use it, save arduino.mk somewhere (I keep mine at
40
# ~/src/arduino.mk) and create a symlink to it in your project directory named
41
# "Makefile". For example:
43
# $ ln -s ~/src/arduino.mk Makefile
45
# The Arduino software (version 1.0 or later) is required. If you are using
46
# Debian (or a derivative), type `apt-get install arduino`. Otherwise, you
47
# will have to download the Arduino software manually from http://arduino.cc/.
48
# It is suggested that you install it at ~/opt/arduino if you are unsure.
50
# If you downloaded the Arduino software manually and unpacked it somewhere
51
# other than ~/opt/arduino, you will need to set up ARDUINODIR to be the path
52
# where you unpacked it. (If unset, ARDUINODIR defaults to ~/opt/arduino and
53
# then /usr/share/arduino, in that order.) You might be best to set this in
54
# your ~/.profile by adding something like this:
56
# export ARDUINODIR=~/somewhere/arduino-1.0
58
# You will also need to set BOARD to the type of Arduino you're building for.
59
# Type `make boards` for a list of acceptable values. You could set a default
60
# in your ~/.profile if you want, but it is suggested that you specify this at
61
# build time, especially if you work with different types of Arduino. For
67
# You may also need to set SERIALDEV if it is not detected correctly.
69
# The presence of a .ino (or .pde) file causes the arduino.mk to automatically
70
# determine values for SOURCES, TARGET and LIBRARIES. Any .c, .cc and .cpp
71
# files in the project directory (or any "util" or "utility" subdirectories)
72
# are automatically included in the build and are scanned for Arduino libraries
73
# that have been #included. Note, there can only be one .ino (or .pde) file.
75
# Alternatively, if you want to manually specify build variables, create a
76
# Makefile that defines SOURCES and LIBRARIES and then includes arduino.mk.
77
# (There is no need to define TARGET). Here is an example Makefile:
79
# SOURCES := main.cc other.cc
81
# include ~/src/arduino.mk
83
# Here is a complete list of configuration parameters:
85
# ARDUINODIR The path where the Arduino software is installed on your system.
87
# ARDUINOCONST The Arduino software version, as an integer, used to define the
88
# ARDUINO version constant. This defaults to 100 if undefined.
90
# AVRDUDECONF The avrdude.conf to use. If undefined, this defaults to a guess
91
# based on where the avrdude in use is. If empty, no avrdude.conf
92
# is passed to avrdude (to the system default is used).
94
# AVRTOOLSPATH A space-separated list of directories to search in order when
95
# looking for the avr build tools. This defaults to the system PATH
96
# followed by subdirectories in ARDUINODIR if undefined.
98
# BOARD Specify a target board type. Run `make boards` to see available
101
# LIBRARIES A list of Arduino libraries to build and include. This is set
102
# automatically if a .ino (or .pde) is found.
104
# SERIALDEV The unix device name of the serial device that is the Arduino.
105
# If unspecified, an attempt is made to determine the name of a
106
# connected Arduino's serial device.
108
# SOURCES A list of all source files of whatever language. The language
109
# type is determined by the file extension. This is set
110
# automatically if a .ino (or .pde) is found.
112
# TARGET The name of the target file. This is set automatically if a
113
# .ino (or .pde) is found, but it is not necessary to set it
116
# This makefile also defines the following goals for use on the command line
119
# all This is the default if no goal is specified. It builds the
120
# target and uploads it.
122
# target Builds the target.
124
# upload Uploads the last built target to an attached Arduino.
126
# clean Deletes files created during the build.
128
# boards Display a list of available board names, so that you can set the
129
# BOARD environment variable appropriately.
131
# monitor Start `screen` on the serial device. This is meant to be an
132
# equivalent to the Arduino serial monitor.
134
# size Displays size information about the bulit target.
136
# <file> Builds the specified file, either an object file or the target,
137
# from those that that would be built for the project.
