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

31

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

32

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

33

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

34

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

35

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

36

38

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

41

39

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

45

43

#

46

44

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

47

45

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

48

# "Makefile" and run make (remembering to specify an ARDUINODIR and

49

# BOARD, as described below). You would create the symlink like like

50

# so:

46

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

47

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

51

48

#

52

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

49

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

53

50

#

54

51

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

55

52

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

65

62

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

66

63

# Makefile:

67

64

#

68

# SOURCES := main.cc foo.cc

69

# LIBRARIES := EEPROM

70

# include ~/src/arduino.mk

65

# SOURCES := main.cc foo.cc

66

# LIBRARIES := EEPROM

67

# include ~/src/arduino.mk

69

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

73

70

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

74

# are better specified in the environment (or on the command line)

75

# than in your Makefile. Specifically, the ARDUINODIR, BOARD and, if

76

# it is not automatically detected, SERIALDEV.

77

#

78

# When running make, you might want to specify the board and path to

79

# your installation of the arduino software, like this:

80

#

81

# $ export ARDUINODIR=~/opt/arduino-1.0

82

# $ export BOARD=pro5v

83

# $ make

71

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

72

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

73

# automatically detected).

74

#

75

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

76

#

77

# $ BOARD=pro5v make

78

#

79

# Or in the environment:

80

#

81

# $ export BOARD=pro5v

82

# $ make

84

83

#

85

84

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

86

85

#

87

# Here is a complete list of configuration parameters:

88

#

89

# ARDUINODIR The path where you have installed/unpacked the arduino

90

# software (from http://arduino.cc/)

86

# Here is a list of all configuration parameters:

91

87

#

92

88

# BOARD Specify a target board type.

93

89

#

95

91

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

96

92

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

97

93

#

98

# TARGET The name of the target file. This is set automatically

99

# if a .ino or .pde is found, but it is not neccesary to

100

# set it otherwise.

94

# The following configuration parameters can be determined automatically:

95

#

96

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

97

# is not determined automatically.

101

98

#

102

99

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

103

100

# language type is determined by the file extension.

104

# This is set automatically if a .ino or .pde is found.

105

101

#

106

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

107

# is set automatically if a .ino or .pde is found.

102

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

108

103

#

109

104

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

110

105

# use on the command line when you run make:

122

117

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

123

118

# project.

124

119

#

125

# boards This is not a real goal. It just displays a list of

126

# available board names, so that you can set the BOARD

127

# environment variable appropriately.

128

#

129

# monitor This is not a real goal. It starts screen on the serial

130

# device. It is ment to be an equivelant to the arduino

131

# serial monitor.
