38

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

39

# build system. To use it, just copy arduino.mk in to your project directory.

40

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

41

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

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:

42

#

43

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

45

# The Arduino software (version 1.0 or later) is required. On GNU/Linux you

46

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

47

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

48

# you can download the Arduino software manually from http://arduino.cc/. It

49

# is suggested that you install it at ~/opt/arduino (or /Applications on OS X)

50

# if you are unsure.

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.

51

#

52

50

# 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 path where you unpacked it. (If

55

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

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

56

54

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

57

55

#

58

56

# export ARDUINODIR=~/somewhere/arduino-1.0

59

57

#

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:

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:

63

#

64

# $ export BOARD=uno

65

# $ make

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 in

74

# a project directory and if you want to be compatible with the Arduino IDE, it

75

# should be called the same as the directory name.

73

# that have been #included. Note, there can only be one .ino (or .pde) file.

76

74

#

77

75

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

78

76

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

79

# (There is no need to define TARGET). You can also specify the BOARD here, if

80

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

77

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

81

78

#

82

79

# SOURCES := main.cc other.cc

83

# LIBRARIES := EEPROM

# BOARD := pro5v

# Here is a complete list of configuration parameters:

92

88

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

93

89

#

94

90

# AVRDUDECONF The avrdude.conf to use. If undefined, this defaults to a guess

95

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

96

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

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).

97

93

#

98

94

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

99

95

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

116

112

#

117

113

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

118

114

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

119

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

120

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

115

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

121

116

#

122

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

123

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

124

# connected Arduino's serial device, which may work in some cases.

117
