# 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
#
42
# BOARD = nano
43
# SERIALDEV = /dev/ttyACM0
44
# include ~/src/arduino.mk

# This is a general purpose makefile for use with Arduino hardware and
31
# software. It works with the arduino-1.0 release and requires that
32
# software to be downloaded separately (see http://arduino.cc/). To
33
# download the latest version of this makefile, visit the following
34
# website, where you can also find more information and documentation
35
# on it's use. The following text can only really be considered a
36
# reference to it's use.

40
# To install, it is suggested that you keep arduino.mk somewhere and
41
# either symlink to it or include it in your make files. I keep mine
42
# at ~/src/arduino.mk. You will need to alter the value of the
43
# ARDUINODIR variable (below) to be the path where you have unpacked
44
# the arduino software from arduino.cc.
45
#
46
# This makefile can be used as a drop-in replacement for the Arduino
47
# IDE's build system. Simply create a symlink to it under the name
48
# "Makefile" and run make as described below (remembering to specify a
49
# BOARD). You would create the symlink like like so:
50
#
51
# $ ln -s ~/src/arduino.mk Makefile
52
#
53
# The presence of a .ino or .pde file causes the arduino.mk to
54
# atuomatically determine va;ues for SOURCES, TARGET and LIBRARIES.
55
# Any .c, .cc and .cpp files in the project directory (or a "util" or
56
# "utility" subdirectory) are automatically included in the build and
57
# are scanned for libraries that have been #included.
58
#
59
# Alternatively, if you want to manually specify build variables,
60
# create a Makefile that defines SOURCES and LIBRARARIES and then
61
# includes arduino.mk. (There is no need to define TARGET). You will
62
# also be expected to provide a main() function, for example in
63
# main.cc, which may or may not duplicate the functionality of the
64
# default main() that calls init() and loop(). Here is an example
65
# Makefile:
66
#
67
# SOURCES := main.cc foo.cc
68
# LIBRARIES := EEPROM
69
# include ~/src/arduino.mk
45

#

71
# 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
#
72
# follows shortly. It should be noted, however, that some variables
73
# are better specified in the environment or on the command line than
74
# in a Makefile. Specifically, the BOARD and SERIALDEV (if it is not
75
# automatically detected).
76
#
77
# When running make, you might want to specify the board type:
78
#
79
# $ BOARD=pro5v make
80
#
81
# Or in the environment:
82
#
83
# $ export BOARD=pro5v
84
# $ make
85
#
86
# For a list of available board types, run `make boards`.
87
#
67
88
# Here is a list of all configuration parameters:
68
89
#
69
# BOARD Specify a target board type. These are defined in boards.txt,
70
# which came with your arduino installation. If unspecified,
71
# a default is used. (See below).
90
# BOARD Specify a target board type.
72
91
#
73
# SERIALDEV The unix device of the device where the arduino can be found.
74
# If unspecified, a default is used. (See below).
92
# SERIALDEV The unix device of the device where the arduino can be
93
# found. If unspecified, an attempt is made to determine
94
# the name of a connected arduino's serial device.
75
95
#
76
96
# The following configuration parameters can be determined automatically:
77
97
#
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
# This general-purpose makefile also defines the following goals for use on the
88
# command line when you run make:
89
#
90
# all This is the default if no goal is specified. It builds the
91
# target and uploads it.
98
# TARGET The name of the target file. This need not be set if it
99
# is not determined automatically.
100
#
101
# SOURCES A list of all source files of whatever language. The
102
