# 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.
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.
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:
51
# SOURCES = main.cc foo.cc
53
# SERIALDEV = /dev/ttyACM0
54
# include ~/src/arduino.mk
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.
61
# When using manual mode, the following variables can be used:
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.
67
# SOURCES A list of all source files of whatever language. The language
68
# type is determined by the file extension.
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).
74
# SERIALDEV The unix device name of the device where the arduino can be
75
# found. If unspecified, a default is used. (See below).
77
# This general-purpose makefile also defines the following goals for use on the
78
# command line when you run make:
80
# all This is the default if no goal is specified. It builds the
81
# target and uploads it.
30
# 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.
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 (remembering to specify an ARDUINODIR and
49
# BOARD, as described below). You would create the symlink like like
52
# $ ln -s ~/src/arduino.mk Makefile
54
# The presence of a .ino or .pde file causes the arduino.mk to
55
# atuomatically determine va;ues for SOURCES, TARGET and LIBRARIES.
56
# Any .c, .cc and .cpp files in the project directory (or a "util" or
57
# "utility" subdirectory) are automatically included in the build and
58
# are scanned for libraries that have been #included.
60
# Alternatively, if you want to manually specify build variables,
61
# create a Makefile that defines SOURCES and LIBRARARIES and then
62
# includes arduino.mk. (There is no need to define TARGET). You will
63
# also be expected to provide a main() function, for example in
64
# main.cc, which may or may not duplicate the functionality of the
65
# default main() that calls init() and loop(). Here is an example
68
# SOURCES := main.cc foo.cc
70
# include ~/src/arduino.mk
72
# A complete list of all the settings you can use in your Makefile
73
# follows shortly. It should be noted, however, that some variables
74
# are better specified in the environment (or on the command line)
75
# than in your Makefile. Specifically, the ARDUINODIR, BOARD and, if
76
# it is not automatically detected, SERIALDEV.
78
# When running make, you might want to specify the board and path to
79
# your installation of the arduino software, like this:
81
# $ export ARDUINODIR=~/opt/arduino-1.0
82
# $ export BOARD=pro5v
85
# For a list of available board types, run `make boards`.
87
# Here is a complete list of configuration parameters:
89
# ARDUINODIR The path where you have installed/unpacked the arduino
90
# software (from http://arduino.cc/)
92
# BOARD Specify a target board type.
94
# SERIALDEV The unix device of the device where the arduino can be
95
# found. If unspecified, an attempt is made to determine
96
# the name of a connected arduino's serial device.
98
# TARGET The name of the target file. This is set automatically
99
# if a .ino or .pde is found, but it is not neccesary to
102
# SOURCES A list of all source files of whatever language. The
103
# language type is determined by the file extension.
104
# This is set automatically if a .ino or .pde is found.
106
# LIBRARIES A list of arduino libraries to build and include. This
107
# is set automatically if a .ino or .pde is found.
109
# This general-purpose makefile also defines the following goals for
110
# use on the command line when you run make:
112
# all This is the default if no goal is specified. It builds
113
# the target and uploads it.
