# This is a general purpose makefile for use with Arduino (arduino.cc)

31

# hardware and software. It works with the arduino-1.0 release and

32

# requires that to be downloaded separately. It can be downloaded

33

# from http://ed.am/dev/make/arduino-makefile where you can also find

34

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

35

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

36

#

37

# To use this makefile, put a file named "Makefile" in your project

38

# directory. Add all your project's settings to your Makefile and

39

# then include this file from it. For example, your Makefile might

40

# look something like this:

41

#

32

# requires that to be downloaded separately.

33

#

34

# There are two ways to use this file, an automatic mode and a manual

35

# mode. In automatic mode, you simply copy this makefile to your

36

# arduino project directory, rename it "Makefile" and type make. The

37

# project directory is expected to contain an .ino or .pde file, which

38

# will automatically be used automatically, along with any other .c,

39

# .cc or .cpp files in the project directory and any subdirectory

40

# named "utility". In this way, this makefile should act as a drop-in

41

# replacement for the Arduino IDE's build process and can build a

42

# project automatically from the files in a project directory.

43

#

44

# Alternatively, you can manually specify what files should be

45

# inclided in a build. To use this makefile manually, you might be

46

# better to keep it somewhere and include it in your project's

47

# Makefile after having defined certain parameters that control the

48

# build. As an example, consider the following Makefile:

49

#

50

# TARGET = my_program

51

# SOURCES = main.cc foo.cc

42

52

# BOARD = nano

43

53

# SERIALDEV = /dev/ttyACM0

44

54

# include ~/src/arduino.mk

45

55

#

46

# A complete list of all the settings you can use in your Makefile

47

# follows shortly. But it should be noted that there are two ways to

48

# use this file, an automatic mode and a manual mode.

49

#

50

# In automatic mode, you simply define a BOARD and SERIALDEV and then

51

# include this makefile. The project directory must contain an .ino

52

# or .pde file, which will automatically be used, along with any other

53

# .c, .cc or .cpp files in the project directory. When buliding, any

54

# arduino libraries that are #included in your code are detected and

55

# automatically linked against. In this way, this makefile should act

56

# as a drop-in replacement for the Arduino IDE's build system. You

57

# should be able to type "make" from the command line and achieve the

58

# same as building and uploading from the Arduino IDE.

59

#

60

# The alternative, manual mode, makes no assumptions. If the

61

# directory doesn't contain an .ino or .pde file, you must also

62

# specify the SOURCES, TARGET and LIBRARIES manually in your Makefile.

63

# You will also be expected to provide a main() function, for example

64

# in main.cc, which may or may not duplicate the functionality of the

65

# default main() that calls init() and loop().

66

#

67

# Here is a list of all configuration parameters:

56

# In both manual and automatic modes, the standard Arduino main.cpp's

57

# main() is included, which expects to be able to call init() and

58

# loop() in your code. The main difference is that, in manual mode,

59

# these would typically be placed in a .cc or .cpp file.

60

#

61

# When using manual mode, the following variables can be used:

62

#

63

# TARGET The name of the target file. This is typically the same name

64

# as the project directory for an arduino project and, if

65

# unspecified, that is used as a default.

66

#

67

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

68

# type is determined by the file extension.

68

69

#

69

70

# BOARD Specify a target board type. These are defined in boards.txt,

70

71

# which came with your arduino installation. If unspecified,

73

74

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

74

75

# If unspecified, a default is used. (See below).

75

76

#

76

# The following configuration parameters can be determined automatically:

77

#

78

# TARGET The name of the target file. This is typically the same name

79

# as the project directory for an arduino project and, if

80

# unspecified, that is used as a default.

81

#

82

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

83

# type is determined by the file extension.

84

#

85

# LIBRARIES A list of arduino libraries to include

86

#

87

77

# This general-purpose makefile also defines the following goals for use on the

88

78

# command line when you run make:

89

79

#

129

119

# atmega168 Arduino NG or older w/ ATmega168
