# 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 (remembering to specify an ARDUINODIR and
49
# BOARD, as described below). You would create the symlink like like
50
# so:
31
# software. It works with the arduino-1.0 release and requires that software
32
# to be downloaded separately (see http://arduino.cc/). To download the latest
33
# version of this makefile, visit the following website, where you can also
34
# find more information and documentation on it's use. The following text can
35

38
#
39
# This makefile can be used as a drop-in replacement for the Arduino IDE's
40
# build system. To use it, save arduino.mk somewhere (I keep mine at
41
# ~/src/arduino.mk) and create a symlink to it in your project directory named
42
# "Makefile". For example:
51
43
#
52
44
# $ ln -s ~/src/arduino.mk Makefile
53
45
#
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.
59
#
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
66
# Makefile:
67
#
68
# SOURCES := main.cc foo.cc
46
# 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
49
# your ~/.profile by adding something like this:
50
#
51
# export ARDUINODIR=~/somewhere/arduino-1.0
52
#
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:
56
#
57
# $ export BOARD=uno
58
# $ make
59
#
60
# You may also need to set SERIALDEV if it is not detected correctly.
61
#
62
# The presence of a .ino (or .pde) file causes the arduino.mk to automatically
63
# determine values for SOURCES, TARGET and LIBRARIES. Any .c, .cc and .cpp
64
# files in the project directory (or any "util" or "utility" subdirectories)
65
# are automatically included in the build and are scanned for Arduino libraries
66
# that have been #included. Note, there can only be one .ino (or .pde) file.
67
#
68
# Alternatively, if you want to manually specify build variables, create a
69
# Makefile that defines SOURCES and LIBRARIES and then includes arduino.mk.
70
# (There is no need to define TARGET). Here is an example Makefile:
71
#
72
# SOURCES := main.cc other.cc
69
73
# LIBRARIES := EEPROM
70
74
# include ~/src/arduino.mk
71
75
#
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.
77
#
78
# When running make, you might want to specify the board and path to
79
# your installation of the arduino software, like this:
80
#
81
# $ export ARDUINODIR=~/opt/arduino-1.0
82
# $ export BOARD=pro5v
83
# $ make
84
#
85
# For a list of available board types, run `make boards`.
86
#
87
76
# Here is a complete list of configuration parameters:
88
77
#
89
# ARDUINODIR The path where you have installed/unpacked the arduino
90
# software (from http://arduino.cc/)
91
#
92
# BOARD Specify a target board type.
93
#
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.
97
#
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
100
# set it otherwise.
101
#
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.
105
#
106
# LIBRARIES A list of arduino libraries to build and include. This
107
# is set automatically if a .ino or .pde is found.
108
#
109
# This general-purpose makefile also defines the following goals for
110
# use on the command line when you run make:
111
#
112
# all This is the default if no goal is specified. It builds
113
# the target and uploads it.
114
#
115
# target Builds the target of your Makefile.
116
#
117
# upload Uploads the target to an attached arduino.
118
#
119
# clean Deletes temporary files.
120
#
121
# <file> Builds the specified file, either an object file or the
122
# target, from those that that would be built for the
123
# project.
124
#
125
# boards This is not a real goal. It just displays a list of
126
# available board names, so that you can set the BOARD
127
# environment variable appropriately.
128
#
129
# monitor This is not a real goal. It starts screen on the serial
130
# device. It is ment to be an equivelant to the arduino
131
# serial monitor.
78
# ARDUINODIR The path where you have installed/unpacked the arduino software
79
# (from http://arduino.cc/)
80
#
81
# BOARD Specify a target board type. Run `make boards` to see available
82
# board types.
83
#
84
# SERIALDEV The unix device name of the serial device that is the arduino.
85
# If unspecified, an attempt is made to determine the name of a
86
# connected arduino's serial device.
87
#
88
# 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
90
# otherwise.
91
#
92
# SOURCES A list of all source files of whatever language. The language
93
# type is determined by the file extension. This is set
94
# automatically if a .ino (or .pde) is found.
95
#
96
# LIBRARIES A list of arduino libraries to build and include. This is set
97
# automatically if a .ino (or .pde) is found.
98
#
99
# This makefile also defines the following goals for use on the command line
100
# when you run make:
101
#

# all This is the default if no goal is specified. It builds the
103
# target and uploads it.
104
#
105
# target Builds the target.
106
#
107
# upload Uploads the last built target to an attached arduino.
108
#
109
# clean Deletes files created during the build.
110
#
111
# boards Display a list of available board names, so that you can set the
112
# BOARD environment variable appropriately.
113
#
114
# monitor Start `screen` on the serial device. This is meant to be an
115
# equivalent to the arduino serial monitor.
116
#
117
# <file> Builds the specified file, either an object file or the target,
118
# from those that that would be built for the project.
