# 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

38
39
# This makefile can be used as a drop-in replacement for the Arduino IDE's
39
# build system. To use it, just copy arduino.mk in to your project directory.
40
# Or, you could save it somewhere (I keep mine at ~/src/arduino.mk) and create
41
# a symlink to it in your project directory, named "Makefile". For example:
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:
43
44
# $ ln -s ~/src/arduino.mk Makefile
45
# The Arduino software (version 1.0 or later) is required. On GNU/Linux you
46
# can probably install the software from your package manager. If you are
47
# using Debian (or a derivative), try `apt-get install arduino`. Otherwise,
48
# you can download the Arduino software manually from http://arduino.cc/. It
49
# is suggested that you install it at ~/opt/arduino (or /Applications on OS X)
52
# If you downloaded the Arduino software manually and unpacked it somewhere
53
# other than ~/opt/arduino (or /Applications), you will need to set up the
54
# ARDUINODIR environment variable to be the path where you unpacked it. (If
55
# unset, ARDUINODIR defaults to some sensible places). You could set this in
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
56
49
# your ~/.profile by adding something like this:
58
51
# export ARDUINODIR=~/somewhere/arduino-1.0
60
# For each project, you will also need to set BOARD to the type of Arduino
61
# you're building for. Type `make boards` for a list of acceptable values.
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:
64
57
# $ export BOARD=uno
70
63
# determine values for SOURCES, TARGET and LIBRARIES. Any .c, .cc and .cpp
71
64
# files in the project directory (or any "util" or "utility" subdirectories)
72
65
# 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 in
74
# a project directory and if you want to be compatible with the Arduino IDE, it
75
# should be called the same as the directory name.
66
# that have been #included. Note, there can only be one .ino (or .pde) file.
77
68
# Alternatively, if you want to manually specify build variables, create a
78
69
# Makefile that defines SOURCES and LIBRARIES and then includes arduino.mk.
79
# (There is no need to define TARGET). You can also specify the BOARD here, if
80
# the project has a specific one. Here is an example Makefile:

87
76
# Here is a complete list of configuration parameters:
89
# ARDUINODIR The path where the Arduino software is installed on your system.
91
# ARDUINOCONST The Arduino software version, as an integer, used to define the
92
# ARDUINO version constant. This defaults to 100 if undefined.
94
# AVRDUDECONF The avrdude.conf to use. If undefined, this defaults to a guess
95
# based on where avrdude is. If set empty, no avrdude.conf is
96
# passed to avrdude (so the system default is used).
98
# AVRDUDEFLAGS Specify any additional flags for avrdude. The usual flags,
99
# required to build the project, will be appended to this.
101
# AVRTOOLSPATH A space-separated list of directories that is searched in order
102
# when looking for the avr build tools. This defaults to PATH,
103
# followed by subdirectories in ARDUINODIR.
78
# ARDUINODIR The path where you have installed/unpacked the arduino software
79
# (from http://arduino.cc/)
105
81
# BOARD Specify a target board type. Run `make boards` to see available
108
# CPPFLAGS Specify any additional flags for the compiler. The usual flags,
109
# required to build the project, will be appended to this.
111
# LINKFLAGS Specify any additional flags for the linker. The usual flags,
112
# required to build the project, will be appended to this.
114
# LIBRARIES A list of Arduino libraries to build and include. This is set
115
# automatically if a .ino (or .pde) is found.
117
# LIBRARYPATH A space-separated list of directories that is searched in order
118
# when looking for Arduino libraries. This defaults to "libs",
119
# "libraries" (in the project directory), then your sketchbook
120
# "libraries" directory, then the Arduino libraries directory.
122
# SERIALDEV The POSIX device name of the serial device that is the Arduino.
123
# If unspecified, an attempt is made to guess the name of a
124
# connected Arduino's serial device, which may work in some cases.
126
# SOURCES A list of all source files of whatever language. The language
127
# type is determined by the file extension. This is set
128
# automatically if a .ino (or .pde) is found.
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.
130
88
# TARGET The name of the target file. This is set automatically if a
131
89
# .ino (or .pde) is found, but it is not necessary to set it
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.
96
# LIBRARIES A list of arduino libraries to build and include. This is set
97
# automatically if a .ino (or .pde) is found.
134
99
# This makefile also defines the following goals for use on the command line
135
100
# when you run make:
137
102
# all This is the default if no goal is specified. It builds the
103
# target and uploads it.
140
105
# target Builds the target.
142
# upload Uploads the target (building it, as necessary) to an attached
107
# upload Uploads the last built target to an attached arduino.
145
109
# clean Deletes files created during the build.
148
112
# BOARD environment variable appropriately.
150
114
# monitor Start `screen` on the serial device. This is meant to be an
151
# equivalent to the Arduino serial monitor.
153
# size Displays size information about the built target.
155
# bootloader Burns the bootloader for your board to it.
115
# equivalent to the arduino serial monitor.
157
117
# <file> Builds the specified file, either an object file or the target,
