# 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

# 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.

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:

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 (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.

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).

49

51

#

50

52

# 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:

55

#

56

# export ARDUINODIR=~/somewhere/arduino-1.0

57

#

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

62

# example:

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

# $ make

66

#

67

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

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.

68

73

#

69

74

# 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

# 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.

74

82

#

75

83

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

76

84

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

77

# (There is no need to define TARGET). Here is an example Makefile:

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:

78

87

#

79

88

# SOURCES := main.cc other.cc

80

89

# LIBRARIES := EEPROM

90

# BOARD := pro5v

81

91

# include ~/src/arduino.mk

83

# Here is a complete list of configuration parameters:

93

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

84

94

#

85

# ARDUINODIR The path where the Arduino software is installed on your system.

95

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

86

96

#

87

97

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

88

98

# ARDUINO version constant. This defaults to 100 if undefined.

89

99

#

90

100

# 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).

101

# based on where avrdude is. If set empty, no avrdude.conf is

102

# passed to avrdude (so the system default is used).

93

103

#

94

104

# AVRDUDEFLAGS Specify any additional flags for avrdude. The usual flags,

95

105

# required to build the project, will be appended to this.

99

109

# followed by subdirectories in ARDUINODIR.

100

110

#

101

111

# BOARD Specify a target board type. Run `make boards` to see available

102

# board types.

112

# board types. For Arduino 1.5, you will also need to specify a

113

# processor if the board supports multiple processors (see above).

103

114

#

104

115

# CPPFLAGS Specify any additional flags for the compiler. The usual flags,

105

116

# required to build the project, will be appended to this.

112

123

#

113

124

# LIBRARYPATH A space-separated list of directories that is searched in order

114

125

# when looking for Arduino libraries. This defaults to "libs",

115

# "libraries" and then the Arduino software's libraries directory.

126

# "libraries" (in the project directory), then your sketchbook

127

# "libraries" directory, then the Arduino libraries directory.

116

128

#

117

# SERIALDEV The unix device name of the serial device that is the Arduino.

118

# If unspecified, an attempt is made to determine the name of a

119

# connected Arduino's serial device.

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.

120

132

#

121

133

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

122

134

# type is determined by the file extension. This is set

134

146

#

135

147

# target Builds the target.

136

148

#

137

# upload Uploads the last built target to an attached Arduino.

149

# upload Uploads the target (building it, as necessary) to an attached

150

# Arduino.

138

151

#

139

152

# clean Deletes files created during the build.

140

153

#

144

157

# monitor Start `screen` on the serial device. This is meant to be an

145

158

# equivalent to the Arduino serial monitor.

146

159

#

147

# size Displays size information about the bulit target.

160

# size Displays size information about the built target.

161

#

162

# bootloader Burns the bootloader for your board to it.

148

163

149

164

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