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

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

# 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

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 unset.

83

#

84

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

85

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

86

# followed by subdirectories in ARDUINODIR if unset.

87

#

81

88

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

82

89

# board types.

83

90

#

84

# SERIALDEV The unix device of the device where the arduino can be found.

91

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

92

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

93

#

94

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

85

95

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

86

96

# connected arduino's serial device.

87

97

#

98

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

99

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

100

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

101

#

88

102

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

89

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

103

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

90

104
