# This is a general purpose makefile for use with Arduino hardware and
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.)
36
#
37
# http://ed.am/dev/make/arduino-mk
38
#
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:
42
#
43
# $ ln -s ~/src/arduino.mk Makefile
44
#
45
# The Arduino software is required, version 1.0 or later, including version 1.5
46
# (which is in BETA at time of release of this makefile). On GNU/Linux you can
47
# probably install the software from your package manager. If you are using
48
# Debian (or a derivative), try `apt-get install arduino`. Otherwise, you can
49
# download the latest Arduino software manually from http://arduino.cc/. In
50
# case you're unsure, install it at ~/opt/arduino (or /Applications on OS X).
51
#
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:
57
#
58
# export ARDUINODIR=~/somewhere/arduino-1.0.5
59
#
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.
62
# For example:
63
#
64
# $ export BOARD=uno
65
#
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:
69
#
70
# $ export BOARD=mini.atmega328
71
#
72
# You may also need to set SERIALDEV if your Arduino is not detected correctly.
73
#
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.
82
#
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:
87
#
88
# SOURCES := main.cc other.cc
89
# LIBRARIES := EEPROM
90
# BOARD := pro5v
91
# include ~/src/arduino.mk
92
#
93
# Here is a complete list of environment variables that affect the build:
94
#
95
# ARDUINODIR The directory where the Arduino software resides on your system.
96
#
97
# ARDUINOCONST The Arduino software version, as an integer, used to define the
98
# ARDUINO version constant. This defaults to 100 if undefined.
99
#
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).
103
#
104
# AVRDUDEFLAGS Specify any additional flags for avrdude. The usual flags,
105
# required to build the project, will be appended to this.
106
#
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.
110
#
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).
114
#
115
# CPPFLAGS Specify any additional flags for the compiler. The usual flags,
116
# required to build the project, will be appended to this.
117
#
118
# LINKFLAGS Specify any additional flags for the linker. The usual flags,
119
# required to build the project, will be appended to this.
120
#
121
# LIBRARIES A list of Arduino libraries to build and include. This is set
122
# automatically if a .ino (or .pde) is found.
123
#
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.
128
#
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.
132
#
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.
136
#
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
139
# otherwise.
140
#
141
# This makefile also defines the following goals for use on the command line
142
# when you run make:
143
#
144
# all This is the default if no goal is specified. It builds the
145
# target.
146
#
147
# target Builds the target.
148
#
149
# upload Uploads the target (building it, as necessary) to an attached
150
# Arduino.
151
#
152
# clean Deletes files created during the build.
153
#
154
# boards Display a list of available board names, so that you can set the
155
# BOARD environment variable appropriately.
156
#
157
# monitor Start `screen` on the serial device. This is meant to be an
158
# equivalent to the Arduino serial monitor.
159
#
160
# size Displays size information about the built target.
161
#
162
# bootloader Burns the bootloader for your board to it.
30
# This is a general purpose makefile for use with Arduino (arduino.cc)
31
# hardware and software. It works with the arduino-1.0 release and
32
# requires that to be downloaded separately. It can be downloaded
33
# from http://ed.am/dev/make/arduino-makefile where you can also find
34
# more information and documentation on it's use. The following text
35
# can only really be considered a reference to it's use.
36
#
37
# There are two ways to use this file, an automatic mode and a manual
38
# mode. In automatic mode, you simply copy this makefile to your
39
# arduino project directory, rename it "Makefile" and type make. The
40
# project directory is expected to contain an .ino or .pde file, which
41
# will automatically be used automatically, along with any other .c,
42
# .cc or .cpp files in the project directory and any subdirectory
43
# named "utility". In this way, this makefile should act as a drop-in
44
# replacement for the Arduino IDE's build process and can build a
45
# project automatically from the files in a project directory.
46
#
47
# Alternatively, you can manually specify what files should be
48
# inclided in a build. To use this makefile manually, you might be
49
# better to keep it somewhere and include it in your project's
50
# Makefile after having defined certain parameters that control the
51
# build. As an example, consider the following Makefile:
52
#
53
# TARGET = my_program
54
# SOURCES = main.cc foo.cc
55
# BOARD = nano
56
# SERIALDEV = /dev/ttyACM0
57
# include ~/src/arduino.mk
58
#
59
# In both manual and automatic modes, the standard Arduino main.cpp's
60
# main() is included, which expects to be able to call init() and
61
# loop() in your code. The main difference is that, in manual mode,
62
# these would typically be placed in a .cc or .cpp file.
63
#
64
# When using manual mode, the following variables can be used:
65
#
66
# TARGET The name of the target file. This is typically the same name
67
# as the project directory for an arduino project and, if
68
# unspecified, that is used as a default.
69
#
70
# SOURCES A list of all source files of whatever language. The language
71
# type is determined by the file extension.
72
#
73
# BOARD Specify a target board type. These are defined in boards.txt,
74
# which came with your arduino installation. If unspecified,
75
# a default is used. (See below).
76
#
77
# SERIALDEV The unix device of the device where the arduino can be found.
78
# If unspecified, a default is used. (See below).
79
#
80
# This general-purpose makefile also defines the following goals for use on the
81
# command line when you run make:
82
#
83
# all This is the default if no goal is specified. It builds the
84
# target and uploads it.
85
#
86
# target Builds the target of your Makefile.
87
#
88
# upload Uploads the target to an attached arduino.
89
#
90
# clean Deletes temporary files.
163
91
#
164
92
# <file> Builds the specified file, either an object file or the target,
165
93
# from those that that would be built for the project.
