# 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.
37
#
38
#   http://ed.am/dev/make/arduino-makefile
39
#
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.
45
#
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
50
# so:
51
#
52
#   $ ln -s ~/src/arduino.mk Makefile
53
#
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.
59
#
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
66
# Makefile:
67
#
68
#   SOURCES := main.cc foo.cc
69
#   LIBRARIES := EEPROM
70
#   include ~/src/arduino.mk
71
#
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.
77
#
78
# When running make, you might want to specify the board and path to
79
# your installation of the arduino software, like this:
80
#
81
#   $ export ARDUINODIR=~/opt/arduino-1.0
82
#   $ export BOARD=pro5v
83
#   $ make
84
#
85
# For a list of available board types, run `make boards`.
86
# 
87
# Here is a complete list of configuration parameters:
88
#
89
# ARDUINODIR   The path where you have installed/unpacked the arduino
90
#              software (from http://arduino.cc/)
91
#
92
# BOARD        Specify a target board type.
93
#
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.
97
#
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
100
#              set it otherwise.
101
#
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.
105
#
106
# LIBRARIES    A list of arduino libraries to build and include.  This
107
#              is set automatically if a .ino or .pde is found.
108
#
109
# This general-purpose makefile also defines the following goals for
110
# use on the command line when you run make:
111
#
112
# all          This is the default if no goal is specified. It builds
113
#              the target and uploads it.
114
#
115
# target       Builds the target of your Makefile.
116
#
117
# upload       Uploads the target to an attached arduino.
118
#
119
# clean        Deletes temporary files.
120
#
121
# <file>       Builds the specified file, either an object file or the
122
#              target, from those that that would be built for the
123
#              project.
124
#
125
# boards       This is not a real goal.  It just displays a list of
126
#              available board names, so that you can set the BOARD
127
#              environment variable appropriately.
128
#
129
# monitor      This is not a real goal.  It starts screen on the serial
130
#              device.  It is ment to be an equivelant to the arduino
131
#              serial monitor.
