# 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

# The Arduino software (version 1.0 or later) is required. If you are using

46

# Debian (or a derivative), type `apt-get install arduino`. Otherwise, you

47

# will have to download the arduino software manually from http://arduino.cc/.

48

# It is suggested that you install it at ~/opt/arduino if you are unsure.

49

50

# If you downloaded the Arduino software manually and unpacked it somewhere

51

# other than ~/opt/arduino, you will need to set up ARDUINODIR to be the path

52

# where you unpacked it. (If unset, ARDUINODIR defaults to ~/opt/arduino and

53

# then /usr/share/arduino, in that order.) You might be best to set this in

49

54

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

50

55

#

51

56

# export ARDUINODIR=~/somewhere/arduino-1.0

52

57

#

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:

58

# You will also need to set BOARD to the type of Arduino you're building for.

59

# You could set a default in your ~/.profile if you want, but it is suggested

60

# that you specify this at build time, especially if you work with different

61

# types of Arduino. For example:

56

62

#

57

63

# $ export BOARD=uno

58

64

# $ make

59

65

#

60

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

76

82

# Here is a complete list of configuration parameters:

77

83

#

78

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

79

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

84

# ARDUINODIR The path where the Arduino software is installed on your system.

85

#

86

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

87

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

88

#

89

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

90

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

91

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

92

#

93

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

94

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

95

# followed by subdirectories in ARDUINODIR if undefined.

80

96

#

81

97

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

82

98

# board types.

83

99

#

84

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

100

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

101

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

102

#

103

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

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

86

# connected arduino's serial device.

105

# connected Arduino's serial device.

106

107

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

108

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

109

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

87

110

#

88

111

# 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

112

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

90

113

# otherwise.
