30

# 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.

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

52

# BOARD = nano

53

# SERIALDEV = /dev/ttyACM0

54

# include ~/src/arduino.mk

55

#

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.

69

#

70

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

71

# which came with your arduino installation. If unspecified,

72

# a default is used. (See below).

73

#

74

# SERIALDEV The unix device name of the device where the arduino can be

75

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

76

#

77

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

78

# command line when you run make:

79

#

80

# all This is the default if no goal is specified. It builds the

81

# target and uploads it.

82

#

83

# target Builds the target of your Makefile.

84

#

85

# upload Uploads the target to an attached arduino.

86

#

87

# clean Deletes temporary files.

88

#

89

# <file> Builds the specified file, either an object file or the target,

90

# from those that that would be built for the project.
