# 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
2 by edam
fixed build (missing library), tested upload, and made the .elf file an intermediate file (the .hex file is now the target)
32
# requires that to be downloaded separately.  It can be downloaded
33
# from http://ed.am/dev/make/arduino-makefile where you can also find
34
# more information and documentation on it's use.  The following text
35
# can only really be considered a reference to it's use.

37
# There are two ways to use this file, an automatic mode and a manual
38
# mode.  In automatic mode, you simply copy this makefile to your
39
# arduino project directory, rename it "Makefile" and type make.  The
40
# project directory is expected to contain an .ino or .pde file, which
41
# will automatically be used automatically, along with any other .c,
42
# .cc or .cpp files in the project directory and any subdirectory
43
# named "utility".  In this way, this makefile should act as a drop-in
44
# replacement for the Arduino IDE's build process and can build a
45
# project automatically from the files in a project directory.
46
#
47
# Alternatively, you can manually specify what files should be
48
# inclided in a build.  To use this makefile manually, you might be
49
# better to keep it somewhere and include it in your project's
50
# Makefile after having defined certain parameters that control the
51
# build.  As an example, consider the following Makefile:
52
#
53
#       TARGET = my_program
54
#       SOURCES = main.cc foo.cc
55
#		BOARD = nano
56
#		SERIALDEV = /dev/ttyACM0
57
#       include ~/src/arduino.mk
58
#
59
# In both manual and automatic modes, the standard Arduino main.cpp's
60
# main() is included, which expects to be able to call init() and
61
# loop() in your code.  The main difference is that, in manual mode,
62
# these would typically be placed in a .cc or .cpp file.
63
#
64
# When using manual mode, the following variables can be used:
65
#
66
# TARGET       The name of the target file.  This is typically the same name
67
#              as the project directory for an arduino project and, if
68
#              unspecified, that is used as a default.
69
#
70
# SOURCES      A list of all source files of whatever language. The language
71
#              type is determined by the file extension.
72
#
73
# BOARD        Specify a target board type.  These are defined in boards.txt,
74
#              which came with your arduino installation.  If unspecified,
75
#              a default is used.  (See below).
76
#
77
# SERIALDEV    The unix device of the device where the arduino can be found.
78
#              If unspecified, a default is used.  (See below).
79
#
80
# This general-purpose makefile also defines the following goals for use on the
81
# command line when you run make:
82
#
83
# all          This is the default if no goal is specified. It builds the
84
#              target and uploads it.
85
#
86
# target       Builds the target of your Makefile.
87
#
88
# upload       Uploads the target to an attached arduino.
89
#
90
# clean        Deletes temporary files.
91
#
92
# <file>       Builds the specified file, either an object file or the target,
93
#              from those that that would be built for the project.
