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. 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
34
35
# can only really be considered a reference to it's use.
36
# http://ed.am/dev/make/arduino-mk
38
# This makefile can be used as a drop-in replacement for the Arduino IDE's
39
# build system. To use it, save arduino.mk somewhere (I keep mine at
40
# ~/src/arduino.mk) and create a symlink to it in your project directory named
41
# "Makefile". For example:
43
# $ ln -s ~/src/arduino.mk Makefile
45
# The Arduino software (version 1.0 or later) is required. If you are using
46
# Debian (or a derivative), type `apt-get install arduino`. Otherwise, you
47
# will have to download the Arduino software manually from http://arduino.cc/.
48
# It is suggested that you install it at ~/opt/arduino if you are unsure.
50
# If you downloaded the Arduino software manually and unpacked it somewhere
51
# other than ~/opt/arduino, you will need to set up ARDUINODIR to be the path
52
# where you unpacked it. (If unset, ARDUINODIR defaults to ~/opt/arduino and
53
# then /usr/share/arduino, in that order.) You might be best to set this in
54
# your ~/.profile by adding something like this:
56
# export ARDUINODIR=~/somewhere/arduino-1.0
58
# You will also need to set BOARD to the type of Arduino you're building for.
59
# Type `make boards` for a list of acceptable values. You could set a default
60
# in your ~/.profile if you want, but it is suggested that you specify this at
61
# build time, especially if you work with different types of Arduino. For
67
# You may also need to set SERIALDEV if it is not detected correctly.
69
# The presence of a .ino (or .pde) file causes the arduino.mk to automatically
70
# determine values for SOURCES, TARGET and LIBRARIES. Any .c, .cc and .cpp
71
# files in the project directory (or any "util" or "utility" subdirectories)
72
# are automatically included in the build and are scanned for Arduino libraries
73
# that have been #included. Note, there can only be one .ino (or .pde) file.
75
# Alternatively, if you want to manually specify build variables, create a
76
# Makefile that defines SOURCES and LIBRARIES and then includes arduino.mk.
77
# (There is no need to define TARGET). Here is an example Makefile:
79
# SOURCES := main.cc other.cc
81
# include ~/src/arduino.mk
83
# Here is a complete list of configuration parameters:
85
# ARDUINODIR The path where the Arduino software is installed on your system.
87
# ARDUINOCONST The Arduino software version, as an integer, used to define the
88
# ARDUINO version constant. This defaults to 100 if undefined.
90
# AVRDUDECONF The avrdude.conf to use. If undefined, this defaults to a guess
91
# based on where the avrdude in use is. If empty, no avrdude.conf
92
# is passed to avrdude (to the system default is used).
94
# AVRDUDEFLAGS Specify any additional flags for avrdude. The usual flags,
95
# required to build the project, will be appended to this.
97
# AVRTOOLSPATH A space-separated list of directories that is searched in order
98
# when looking for the avr build tools. This defaults to PATH,
99
# followed by subdirectories in ARDUINODIR.
101
# BOARD Specify a target board type. Run `make boards` to see available
104
# CPPFLAGS Specify any additional flags for the compiler. The usual flags,
105
# required to build the project, will be appended to this.
107
# LINKFLAGS Specify any additional flags for the linker. The usual flags,
108
# required to build the project, will be appended to this.
110
# LIBRARIES A list of Arduino libraries to build and include. This is set
111
# automatically if a .ino (or .pde) is found.
113
# LIBRARYPATH A space-separated list of directories that is searched in order
114
# when looking for Arduino libraries. This defaults to "libs",
115
# "libraries" and then the Arduino software's libraries directory.
117
# SERIALDEV The unix device name of the serial device that is the Arduino.
118
# If unspecified, an attempt is made to determine the name of a
119
# connected Arduino's serial device.
121
# SOURCES A list of all source files of whatever language. The language
122
# type is determined by the file extension. This is set
123
# automatically if a .ino (or .pde) is found.
125
# TARGET The name of the target file. This is set automatically if a
126
# .ino (or .pde) is found, but it is not necessary to set it
129
# This makefile also defines the following goals for use on the command line
132
# all This is the default if no goal is specified. It builds the
135
# target Builds the target.
137
# upload Uploads the last built target to an attached Arduino.
139
# clean Deletes files created during the build.
141
# boards Display a list of available board names, so that you can set the
142
# BOARD environment variable appropriately.
144
# monitor Start `screen` on the serial device. This is meant to be an
145
# equivalent to the Arduino serial monitor.
147
# size Displays size information about the bulit target.
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:
43
# SERIALDEV = /dev/ttyACM0
44
# include ~/src/arduino.mk
46
# 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.
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.
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().
67
# Here is a list of all configuration parameters:
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).
73
# SERIALDEV The unix device of the device where the arduino can be found.
74
# If unspecified, a default is used. (See below).
76
# The following configuration parameters can be determined automatically:
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.
82
# SOURCES A list of all source files of whatever language. The language
83
# type is determined by the file extension.
85
# LIBRARIES A list of arduino libraries to include
87
# This general-purpose makefile also defines the following goals for use on the
88
# command line when you run make:
90
# all This is the default if no goal is specified. It builds the
91
# target and uploads it.
93
# target Builds the target of your Makefile.
95
# upload Uploads the target to an attached arduino.
97
# clean Deletes temporary files.
149
99
# <file> Builds the specified file, either an object file or the target,
150
100
# from those that that would be built for the project.
