#_______________________________________________________________________________

# This is a general purpose makefile for use with Arduino hardware and

# software. It is intended to be a drop-in replacement for the Arduino IDE's

# build system. It works with the Arduino 1.0 and 1.5 software releases, on

# GNU/Linux and OS X. To download the latest version of this makefile visit

# the following website where you can also find documentation on it's use.

# (The following text can only really be considered a reference.)

# http://ed.am/dev/make/arduino-mk

# To use this makefile, copy arduino.mk in to your project directory. Or, you

# could save it somewhere (I keep mine at ~/src/arduino.mk) and create a

# symlink to it in your project directory, named "Makefile". For example:

# software. It works with the arduino-1.0 release and requires that

# software to be downloaded separately (see http://arduino.cc/). To

# download the latest version of this makefile, visit the following

# website, where you can also find more information and documentation

# on it's use. The following text can only really be considered a

# reference to it's use.

# http://ed.am/dev/make/arduino-makefile

# To install, it is suggested that you keep arduino.mk somewhere and

# either symlink to it or include it in your make files. I keep mine

# at ~/src/arduino.mk. You will need to alter the value of the

# ARDUINODIR variable (below) to be the path where you have unpacked

# the arduino software from arduino.cc.

# This makefile can be used as a drop-in replacement for the Arduino

# IDE's build system. Simply create a symlink to it under the name

# "Makefile" and run make as described below (remembering to specify a

# BOARD). You would create the symlink like like so:

# $ ln -s ~/src/arduino.mk Makefile

# The Arduino software is required, version 1.0 or later, including version 1.5

# (which is in BETA at time of release of this makefile). On GNU/Linux you can

# probably install the software from your package manager. If you are using

# Debian (or a derivative), try `apt-get install arduino`. Otherwise, you can

# download the latest Arduino software manually from http://arduino.cc/. In

# case you're unsure, install it at ~/opt/arduino (or /Applications on OS X).

# If you downloaded the Arduino software manually and unpacked it somewhere

# *other* than ~/opt/arduino (or /Applications), you will need to set up the

# ARDUINODIR environment variable to be the directory where you unpacked it.

# (If unset, ARDUINODIR defaults to some sensible places). You could set this

# in your ~/.profile by adding something like this:

# export ARDUINODIR=~/somewhere/arduino-1.0.5

# For each project, you will also need to set BOARD to the type of Arduino

# you're building for. Type `make boards` for a list of acceptable values.

# For example:

# $ export BOARD=uno

# Note that if you're using the newer 1.5 Arduino software and the board you

# want to use is availble with different processors, you will also need to

# specify one. For example:

# $ export BOARD=mini.atmega328

# You may also need to set SERIALDEV if your Arduino is not detected correctly.

# The presence of a .ino (or .pde) file causes the arduino.mk to automatically

# determine values for SOURCES, TARGET and which libraries to pull-in to the

# build (although you can still override thius by setting LIBRARIES). Any .c,

# .cc and .cpp files in the project directory (or any "util" or "utility"

# subdirectories) are automatically included in the build and are scanned for

# Arduino libraries that have been #included. Note, there can only be one .ino

# (or .pde) file in a project directory and if you want to be compatible with

# the Arduino IDE, it should be called the same as the directory name.

# Alternatively, if you want to manually specify build variables, create a

# Makefile that defines SOURCES and LIBRARIES and then includes arduino.mk.

# (You don't need to define TARGET). You can also specify the BOARD here, if

# the project has a specific one. Here is an example Makefile:

# SOURCES := main.cc other.cc

# The presence of a .ino or .pde file causes the arduino.mk to

# atuomatically determine va;ues for SOURCES, TARGET and LIBRARIES.

# Any .c, .cc and .cpp files in the project directory (or a "util" or

# "utility" subdirectory) are automatically included in the build and

# are scanned for libraries that have been #included.

# Alternatively, if you want to manually specify build variables,

# create a Makefile that defines SOURCES and LIBRARARIES and then

# includes arduino.mk. (There is no need to define TARGET). You will

# also be expected to provide a main() function, for example in

# main.cc, which may or may not duplicate the functionality of the

# default main() that calls init() and loop(). Here is an example

# Makefile:

# SOURCES := main.cc foo.cc

# LIBRARIES := EEPROM

# BOARD := pro5v

# include ~/src/arduino.mk

# Here is a complete list of environment variables that affect the build:

# ARDUINODIR The directory where the Arduino software resides on your system.

# ARDUINOCONST The Arduino software version, as an integer, used to define the

# 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).

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.

163

164

# <file> Builds the specified file, either an object file or the target,

165

# from those that that would be built for the project.

# A complete list of all the settings you can use in your Makefile

# follows shortly. It should be noted, however, that some variables

# are better specified in the environment or on the command line than

# in a Makefile. Specifically, the BOARD and SERIALDEV (if it is not

# automatically detected).

# When running make, you might want to specify the board type:

# $ BOARD=pro5v make

# Or in the environment:

# $ export BOARD=pro5v

# $ make

# For a list of available board types, run `make boards`.

# Here is a list of all configuration parameters:

# BOARD Specify a target board type.

# SERIALDEV The unix device of the device where the arduino can be

# found. If unspecified, an attempt is made to determine

# the name of a connected arduino's serial device.

# The following configuration parameters can be determined automatically:

# TARGET The name of the target file. This need not be set if it

# is not determined automatically.

100

101

# SOURCES A list of all source files of whatever language. The

102

# language type is determined by the file extension.

103

104

# LIBRARIES A list of arduino libraries to build and include.

105

106

# This general-purpose makefile also defines the following goals for

107

# use on the command line when you run make:

108

109

# all This is the default if no goal is specified. It builds

110

# the target and uploads it.

111

112

# target Builds the target of your Makefile.

113

114

# upload Uploads the target to an attached arduino.

115

116

# clean Deletes temporary files.

117

118

# <file> Builds the specified file, either an object file or the

119

# target, from those that that would be built for the

120

# project.
