# 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.

# http://ed.am/dev/make/arduino-makefile
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
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

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:
52
44
# $ 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
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:
51
# export ARDUINODIR=~/somewhere/arduino-1.0
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:
60
# You may also need to set SERIALDEV if it is not detected correctly.
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.
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:
72
# SOURCES := main.cc other.cc
69
73
# LIBRARIES := EEPROM
70
74
# 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
76
# 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.
115
# target Builds the target of your Makefile.
117
# upload Uploads the target to an attached arduino.
119
# clean Deletes temporary files.
121
# <file> Builds the specified file, either an object file or the
122
# target, from those that that would be built for the
78
# ARDUINODIR The path where you have installed/unpacked the arduino software
79
# (from http://arduino.cc/)
81
# ARDUINOCONST The arduino software version, as an integer, used to define the
82
# ARDUINO version constant. This defaults to 100 if undefined.
84
# AVRDUDECONF The avrdude.conf to use. If undefined, this defaults to a guess
85
# based on where the avrdude in use is. If empty, no avrdude.conf
86
# is passed to avrdude (to the system default is used).
88
# AVRTOOLSPATH A space-separated list of directories to search in order when
89
# lookin for the avr build tools. This defaults to the system PATH
90
# followed by subdirectories in ARDUINODIR if undefined.
92
# BOARD Specify a target board type. Run `make boards` to see available
95
# LIBRARIES A list of arduino libraries to build and include. This is set
96
# automatically if a .ino (or .pde) is found.
98
# SERIALDEV The unix device name of the serial device that is the arduino.
99
# If unspecified, an attempt is made to determine the name of a
100
# connected arduino's serial device.
102
# SOURCES A list of all source files of whatever language. The language
103
# type is determined by the file extension. This is set
104
# automatically if a .ino (or .pde) is found.
106
# TARGET The name of the target file. This is set automatically if a
107
# .ino (or .pde) is found, but it is not necessary to set it
110
# This makefile also defines the following goals for use on the command line
113
# all This is the default if no goal is specified. It builds the
114
# target and uploads it.
116
# target Builds the target.
118
# upload Uploads the last built target to an attached arduino.
120
# clean Deletes files created during the build.
122
# boards Display a list of available board names, so that you can set the
123
# BOARD environment variable appropriately.
125
# monitor Start `screen` on the serial device. This is meant to be an
126
# equivalent to the arduino serial monitor.
128
# <file> Builds the specified file, either an object file or the target,
129
# from those that that would be built for the project.
