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

33

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

# 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:

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

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

42

#

43

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

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).

# 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.

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:

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

56

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

57

#

58

# export ARDUINODIR=~/somewhere/arduino-1.0.5

58

# export ARDUINODIR=~/somewhere/arduino-1.0

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.

65

# $ make

66

#

67

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

73

68

#

74

69

# 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.

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.

82

76

#

83

77

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

84

78

# 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

79

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

86

80

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

87

81

#

88

82

# SOURCES := main.cc other.cc

90

84

# BOARD := pro5v

91

85

# include ~/src/arduino.mk

93

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

87

# Here is a complete list of configuration parameters:

94

88

#

95

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