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

81

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

93

82

# board types.

94

83

#

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

84

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

99

85

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

100

86

# connected arduino's serial device.

101

87

#

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

88

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

107

89

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

108

90

# otherwise.

109

91

#

92

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

93

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

94

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

95
