# This is a general purpose makefile for use with Arduino hardware and
31
# software. It works with the arduino-1.0 release and requires that
32
# software to be downloaded separately (see http://arduino.cc/). To
33
# download the latest version of this makefile, visit the following
34
# website, where you can also find more information and documentation
35
# on it's use. The following text can only really be considered a
36
# reference to it's use.
38
# http://ed.am/dev/make/arduino-makefile
40
# To install, it is suggested that you keep arduino.mk somewhere and
41
# either symlink to it or include it in your make files. I keep mine
42
# at ~/src/arduino.mk. You will need to alter the value of the
43
# ARDUINODIR variable (below) to be the path where you have unpacked
44
# the arduino software from arduino.cc.
46
# This makefile can be used as a drop-in replacement for the Arduino
47
# IDE's build system. Simply create a symlink to it under the name
48
# "Makefile" and run make as described below (remembering to specify a
49
# BOARD). You would create the symlink like like so:
31
# software. It is intended to be a drop-in replacement for the Arduino IDE's
32
# build system. It works with the Arduino 1.0 and 1.5 software releases, on
33
# GNU/Linux and OS X. To download the latest version of this makefile visit
34
# the following website where you can also find documentation on it's use.
35
# (The following text can only really be considered a reference.)
37
# http://ed.am/dev/make/arduino-mk
39
# To use this makefile, copy arduino.mk in to your project directory. Or, you
40
# could save it somewhere (I keep mine at ~/src/arduino.mk) and create a
41
# symlink to it in your project directory, named "Makefile". For example:
51
43
# $ ln -s ~/src/arduino.mk Makefile
53
# The presence of a .ino or .pde file causes the arduino.mk to
54
# atuomatically determine va;ues for SOURCES, TARGET and LIBRARIES.
55
# Any .c, .cc and .cpp files in the project directory (or a "util" or
56
# "utility" subdirectory) are automatically included in the build and
57
# are scanned for libraries that have been #included.
59
# Alternatively, if you want to manually specify build variables,
60
# create a Makefile that defines SOURCES and LIBRARARIES and then
61
# includes arduino.mk. (There is no need to define TARGET). You will
62
# also be expected to provide a main() function, for example in
63
# main.cc, which may or may not duplicate the functionality of the
64
# default main() that calls init() and loop(). Here is an example
67
# SOURCES := main.cc foo.cc
45
# The Arduino software (version 1.0 or later, including the new 1.5 BETA) is
46
# required. On GNU/Linux you can probably install the software from your
47
# package manager. If you are using Debian (or a derivative), try `apt-get
48
# install arduino`. Otherwise, you can download the Arduino software manually
49
# from http://arduino.cc/. It is suggested that you install it at
50
# ~/opt/arduino (or /Applications on OS X) if you are unsure.
52
# If you downloaded the Arduino software manually and unpacked it somewhere
53
# *other* than ~/opt/arduino (or /Applications), you will need to set up the
54
# ARDUINODIR environment variable to be the directory where you unpacked it.
55
# (If unset, ARDUINODIR defaults to some sensible places). You could set this
56
# in your ~/.profile by adding something like this:
58
# export ARDUINODIR=~/somewhere/arduino-1.0.5
60
# For each project, you will also need to set BOARD to the type of Arduino
61
# you're building for. Type `make boards` for a list of acceptable values.
66
# Note that if you're using the newer 1.5 Arduino software and the board you
67
# want to use is availble with different processors, you will also need to
68
# specify one. For example:
70
# $ export BOARD=mini.atmega328
72
# You may also need to set SERIALDEV if your Arduino is not detected correctly.
74
# The presence of a .ino (or .pde) file causes the arduino.mk to automatically
75
# determine values for SOURCES, TARGET and which libraries to pull-in to the
76
# build (although you can still override thius by setting LIBRARIES). Any .c,
77
# .cc and .cpp files in the project directory (or any "util" or "utility"
78
# subdirectories) are automatically included in the build and are scanned for
79
# Arduino libraries that have been #included. Note, there can only be one .ino
80
# (or .pde) file in a project directory and if you want to be compatible with
81
# the Arduino IDE, it should be called the same as the directory name.
83
# Alternatively, if you want to manually specify build variables, create a
84
# Makefile that defines SOURCES and LIBRARIES and then includes arduino.mk.
85
# (You don't need to define TARGET). You can also specify the BOARD here, if
86
# the project has a specific one. Here is an example Makefile:
88
# SOURCES := main.cc other.cc
68
89
# LIBRARIES := EEPROM
69
91
# include ~/src/arduino.mk
71
# A complete list of all the settings you can use in your Makefile
72
# follows shortly. It should be noted, however, that some variables
73
# are better specified in the environment or on the command line than
74
# in a Makefile. Specifically, the BOARD and SERIALDEV (if it is not
75
# automatically detected).
77
# When running make, you might want to specify the board type:
81
# Or in the environment:
83
# $ export BOARD=pro5v
86
# For a list of available board types, run `make boards`.
88
# Here is a list of all configuration parameters:
90
# BOARD Specify a target board type.
92
# SERIALDEV The unix device of the device where the arduino can be
93
# found. If unspecified, an attempt is made to determine
94
# the name of a connected arduino's serial device.
96
# The following configuration parameters can be determined automatically:
98
# TARGET The name of the target file. This need not be set if it
99
# is not determined automatically.
101
# SOURCES A list of all source files of whatever language. The
102
# language type is determined by the file extension.
104
# LIBRARIES A list of arduino libraries to build and include.
106
# This general-purpose makefile also defines the following goals for
107
# use on the command line when you run make:
109
# all This is the default if no goal is specified. It builds
110
# the target and uploads it.
112
# target Builds the target of your Makefile.
114
# upload Uploads the target to an attached arduino.
116
# clean Deletes temporary files.
118
# <file> Builds the specified file, either an object file or the
119
# target, from those that that would be built for the
93
# Here is a complete list of environment variables that affect the build:
95
# ARDUINODIR The directory where the Arduino software resides on your system.
97
# ARDUINOCONST The Arduino software version, as an integer, used to define the
98
# ARDUINO version constant. This defaults to 100 if undefined.
100
# AVRDUDECONF The avrdude.conf to use. If undefined, this defaults to a guess
101
# based on where avrdude is. If set empty, no avrdude.conf is
102
# passed to avrdude (so the system default is used).
104
# AVRDUDEFLAGS Specify any additional flags for avrdude. The usual flags,
105
# required to build the project, will be appended to this.
107
# AVRTOOLSPATH A space-separated list of directories that is searched in order
108
# when looking for the avr build tools. This defaults to PATH,
109
# followed by subdirectories in ARDUINODIR.
111
# BOARD Specify a target board type. Run `make boards` to see available
112
# board types. For Arduino 1.5, you will also need to specify a
113
# processor if the board supports multiple processors (see above).
115
# CPPFLAGS Specify any additional flags for the compiler. The usual flags,
116
# required to build the project, will be appended to this.
118
# LINKFLAGS Specify any additional flags for the linker. The usual flags,
119
# required to build the project, will be appended to this.
121
# LIBRARIES A list of Arduino libraries to build and include. This is set
122
# automatically if a .ino (or .pde) is found.
124
# LIBRARYPATH A space-separated list of directories that is searched in order
125
# when looking for Arduino libraries. This defaults to "libs",
126
# "libraries" (in the project directory), then your sketchbook
127
# "libraries" directory, then the Arduino libraries directory.
129
# SERIALDEV The POSIX device name of the serial device that is the Arduino.
130
# If unspecified, an attempt is made to guess the name of a
131
# connected Arduino's serial device, which may work in some cases.
133
# SOURCES A list of all source files of whatever language. The language
134
# type is determined by the file extension. This is set
135
# automatically if a .ino (or .pde) is found.
137
# TARGET The name of the target file. This is set automatically if a
138
# .ino (or .pde) is found, but it is not necessary to set it
141
# This makefile also defines the following goals for use on the command line
144
# all This is the default if no goal is specified. It builds the
147
# target Builds the target.
149
# upload Uploads the target (building it, as necessary) to an attached
152
# clean Deletes files created during the build.
154
# boards Display a list of available board names, so that you can set the
155
# BOARD environment variable appropriately.
157
# monitor Start `screen` on the serial device. This is meant to be an
158
# equivalent to the Arduino serial monitor.
160
# size Displays size information about the built target.
162
# bootloader Burns the bootloader for your board to it.
164
# <file> Builds the specified file, either an object file or the target,
165
# from those that that would be built for the project.
