# This is a general purpose makefile for use with Arduino (see
31
# http://arduino.cc/) hardware and software. It works with the
32
# arduino-1.0 release and requires that to be downloaded separately.
33
# It can be downloaded from http://ed.am/dev/make/arduino-makefile
34
# where you can also find more information and documentation on it's
35
# use. The following text can only really be considered a reference
38
# To install, it is suggested that you keep arduino.mk somewhere and
39
# either symlink to it or include it in your make files. I keep mine
40
# at ~/src/arduino.mk. You will need to alter the value of the
41
# ARDUINODIR variable (below) to be the path where you have unpacked
42
# the arduino software from arduino.cc.
44
# This makefile can be used as a drop-in replacement for the Arduino
45
# IDE's build system. Simply create a symlink to it under the name
46
# "Makefile" and run make as described below (remembering to specify a
47
# BOARD). You would create the symlink like like so:
49
# $ ln -s ~/src/arduino.mk Makefile
51
# The presence of a .ino or .pde file causes the arduino.mk to
52
# atuomatically determine va;ues for SOURCES, TARGET and LIBRARIES.
53
# Any .c, .cc and .cpp files in the project directory (or a "util" or
54
# "utility" subdirectory) are automatically included in the build and
55
# are scanned for libraries that have been #included.
57
# Alternatively, if you want to manually specify build variables,
58
# create a Makefile that defines SOURCES and LIBRARARIES and then
59
# includes arduino.mk. (There is no need to define TARGET). You will
60
# also be expected to provide a main() function, for example in
61
# main.cc, which may or may not duplicate the functionality of the
62
# default main() that calls init() and loop(). Here is an example
65
# SOURCES := main.cc foo.cc
67
# include ~/src/arduino.mk
69
# A complete list of all the settings you can use in your Makefile
70
# follows shortly. It should be noted, however, that some variables
71
# are better specified in the environment or on the command line than
72
# in a Makefile. Specifically, the BOARD and SERIALDEV (if it is not
73
# automatically detected).
75
# When running make, you might want to specify the board type:
79
# Or in the environment:
81
# $ export BOARD=pro5v
84
# For a list of available board types, run `make boards`.
86
# Here is a list of all configuration parameters:
88
# BOARD Specify a target board type.
90
# SERIALDEV The unix device of the device where the arduino can be
91
# found. If unspecified, an attempt is made to determine
92
# the name of a connected arduino's serial device.
94
# The following configuration parameters can be determined automatically:
96
# TARGET The name of the target file. This need not be set if it
97
# is not determined automatically.
99
# SOURCES A list of all source files of whatever language. The
100
# language type is determined by the file extension.
102
# LIBRARIES A list of arduino libraries to build and include.
104
# This general-purpose makefile also defines the following goals for
105
# use on the command line when you run make:
107
# all This is the default if no goal is specified. It builds
108
# the target and uploads it.
110
# target Builds the target of your Makefile.
112
# upload Uploads the target to an attached arduino.
114
# clean Deletes temporary files.
116
# <file> Builds the specified file, either an object file or the
117
# target, from those that that would be built for the
