# This makefile can be used as a drop-in replacement for the Arduino IDE's
39
# build system. To use it, just copy arduino.mk in to your project directory.
40
# Or, you could save it somewhere (I keep mine at ~/src/arduino.mk) and create
41
# a symlink to it in your project directory, named "Makefile". For example:

# The Arduino software (version 1.0 or later) is required. On GNU/Linux you
46
# can probably install the software from your package manager. If you are
47

48
# you can download the Arduino software manually from http://arduino.cc/. It
49
# is suggested that you install it at ~/opt/arduino (or /Applications on OS X)

50
# If you downloaded the Arduino software manually and unpacked it somewhere
53
# other than ~/opt/arduino (or /Applications), you will need to set up the
54
# ARDUINODIR environment variable to be the path where you unpacked it. (If
55
# unset, ARDUINODIR defaults to some sensible places). You could set this in
51
# other than ~/opt/arduino, you will need to set up ARDUINODIR to be the path
52
# where you unpacked it. (If unset, ARDUINODIR defaults to ~/opt/arduino and
53
# then /usr/share/arduino, in that order.) You might be best to set this in
56
54
# your ~/.profile by adding something like this:
58
56
# export ARDUINODIR=~/somewhere/arduino-1.0

# For each project, you will also need to set BOARD to the type of Arduino
61
# you're building for. Type `make boards` for a list of acceptable values.

94
90
# AVRDUDECONF The avrdude.conf to use. If undefined, this defaults to a guess

96

# AVRDUDEFLAGS Specify any additional flags for avrdude. The usual flags,
99

# required to build the project, will be appended to this.

# LIBRARYPATH A space-separated list of directories that is searched in order
118
114

120
# "libraries" directory, then the Arduino libraries directory.

123
# If unspecified, an attempt is made to guess the name of a
124
# connected Arduino's serial device, which may work in some cases.
