# 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.
33
#
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.
43
#
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:
49
#
50
#       TARGET = my_program
51
#       SOURCES = main.cc foo.cc
52
#		BOARD = nano
53
#		SERIALDEV = /dev/ttyACM0
54
#       include ~/src/arduino.mk
55
#
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.
60
#
61
# When using manual mode, the following variables can be used:
62
#
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.
66
#
67
# SOURCES      A list of all source files of whatever language. The language
68
#              type is determined by the file extension.
69
#
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).
73
#
74
# SERIALDEV    The unix device of the device where the arduino can be found.
75
#              If unspecified, a default is used.  (See below).
76
#
77
# This general-purpose makefile also defines the following goals for use on the
78
# command line when you run make:
79
#
80
# all          This is the default if no goal is specified. It builds the
81
#              target and uploads it.
82
#
83
# target       Builds the target of your Makefile.
84
#
85
# upload       Uploads the target to an attached arduino.
86
#
87
# clean        Deletes temporary files.
88
#
89
# <file>       Builds the specified file, either an object file or the target,
90
#              from those that that would be built for the project.
