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

# 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

# SOURCES := main.cc other.cc

81

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

82

# board types.

83

84

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

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

85

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

86

# connected arduino's serial device.

87

#

88

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

89

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

90

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.

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