# 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 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
# only really be considered a reference to it's use.
37
# http://ed.am/dev/make/arduino-mk
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:
44
# $ ln -s ~/src/arduino.mk Makefile
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
74
# include ~/src/arduino.mk
76
# Here is a complete list of configuration parameters:
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 unset.
84
# AVRTOOLSPATH A space-separated list of directories to search in order when
85
# lookin for the avr build tools. This defaults to the system PATH
86
# followed by subdirectories in ARDUINODIR if unset.
88
# BOARD Specify a target board type. Run `make boards` to see available
91
# LIBRARIES A list of arduino libraries to build and include. This is set
92
# automatically if a .ino (or .pde) is found.
94
# SERIALDEV The unix device name of the serial device that is the arduino.
95
# If unspecified, an attempt is made to determine the name of a
96
# connected arduino's serial device.
98
# SOURCES A list of all source files of whatever language. The language
99
# type is determined by the file extension. This is set
100
# automatically if a .ino (or .pde) is found.
102
# TARGET The name of the target file. This is set automatically if a
103
# .ino (or .pde) is found, but it is not necessary to set it
106
# This makefile also defines the following goals for use on the command line
109
# all This is the default if no goal is specified. It builds the
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.
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 of the device where the arduino can be found.
75
# 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
110
81
# target and uploads it.
112
# target Builds the target.
114
# upload Uploads the last built target to an attached arduino.
116
# clean Deletes files created during the build.
118
# boards Display a list of available board names, so that you can set the
119
# BOARD environment variable appropriately.
121
# monitor Start `screen` on the serial device. This is meant to be an
122
# equivalent to the arduino serial monitor.
83
# target Builds the target of your Makefile.
85
# upload Uploads the target to an attached arduino.
87
# clean Deletes temporary files.
124
89
# <file> Builds the specified file, either an object file or the target,
125
90
# from those that that would be built for the project.
