30

# 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 software

32

# to be downloaded separately (see http://arduino.cc/). To download the latest

33

# version of this makefile, visit the following website, where you can also

34

# find more information and documentation on it's use. The following text can

35

# only really be considered a reference to it's use.

36

#

37

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

38

#

39

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

40

# build system. To use it, save arduino.mk somewhere (I keep mine at

41

# ~/src/arduino.mk) and create a symlink to it in your project directory named

42

# "Makefile". For example:

43

#

44

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

45

#

46

# You also need to set up a couple of environment variables. ARDUINODIR should

47

# be set to the path where you unpacked the arduino software from arduino.cc

48

# (it defaults to ~/opt/arduino if unset). You might be best to set this in

49

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

50

#

51

# export ARDUINODIR=~/somewhere/arduino-1.0

52

#

53

# You will also need to set BOARD to the type of arduino you're using. This

54

# can be done when running make (or you could set a default in ~/.profile and

55

# override it as necessary). For example:

56

#

57

# $ export BOARD=uno

58

# $ make

59

#

60

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

61

#

62

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

63

# determine values for SOURCES, TARGET and LIBRARIES. Any .c, .cc and .cpp

64

# files in the project directory (or any "util" or "utility" subdirectories)

65

# are automatically included in the build and are scanned for Arduino libraries

66

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

67

#

68

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

69

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

70

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

71

#

72

# SOURCES := main.cc other.cc

73

# LIBRARIES := EEPROM

74

# include ~/src/arduino.mk

75

#

76

# Here is a complete list of configuration parameters:

77

#

78

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

79

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

80

#

81

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

82

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

83

#

84

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

85

# based on where the avrdude in use is. If empty, no avrdude.conf

86

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

87

#

88

# AVRTOOLSPATH A space-separated list of directories to search in order when

89

# lookin for the avr build tools. This defaults to the system PATH

90

# followed by subdirectories in ARDUINODIR if undefined.

91

#

92

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

93

# board types.

94

#

95

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

96

# automatically if a .ino (or .pde) is found.

97

#

98

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

99

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

100

# connected arduino's serial device.

101

#

102

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

103

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

104

# automatically if a .ino (or .pde) is found.

105

#

106

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

107

# .ino (or .pde) is found, but it is not necessary to set it

108

# otherwise.

109

#

110

# This makefile also defines the following goals for use on the command line

111

# when you run make:

112

#

113

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

114

# target and uploads it.

115

#

116

# target Builds the target.

117

#

118

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

119

#

120

# clean Deletes files created during the build.

121

#

122

# boards Display a list of available board names, so that you can set the

123

# BOARD environment variable appropriately.

124

#

125

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

126

# equivalent to the arduino serial monitor.

127

#

128

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

129

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