# To use this makefile, copy arduino.mk in to your project directory. Or, you

# could save it somewhere (I keep mine at ~/src/arduino.mk) and create a

# symlink to it in your project directory, named "Makefile". For example:

# This makefile can be used as a drop-in replacement for the Arduino IDE's

# build system. To use it, save arduino.mk somewhere (I keep mine at

# ~/src/arduino.mk) and create a symlink to it in your project directory named

# "Makefile". For example:

# $ ln -s ~/src/arduino.mk Makefile

# The Arduino software (version 1.0 or later, including the new 1.5 BETA) is

# required. On GNU/Linux you can probably install the software from your

# package manager. If you are using Debian (or a derivative), try `apt-get

# install arduino`. Otherwise, you can download the Arduino software manually

# from http://arduino.cc/. It is suggested that you install it at

# ~/opt/arduino (or /Applications on OS X) if you are unsure.

# The Arduino software (version 1.0 or later) is required. If you are using

# Debian (or a derivative), type `apt-get install arduino`. Otherwise, you

# will have to download the Arduino software manually from http://arduino.cc/.

# It is suggested that you install it at ~/opt/arduino if you are unsure.

# If you downloaded the Arduino software manually and unpacked it somewhere

# *other* than ~/opt/arduino (or /Applications), you will need to set up the

# ARDUINODIR environment variable to be the directory where you unpacked it.

# (If unset, ARDUINODIR defaults to some sensible places). You could set this

# in your ~/.profile by adding something like this:

# export ARDUINODIR=~/somewhere/arduino-1.0.5

# For each project, you will also need to set BOARD to the type of Arduino

# you're building for. Type `make boards` for a list of acceptable values.

# For example:

# other than ~/opt/arduino, you will need to set up ARDUINODIR to be the path

# where you unpacked it. (If unset, ARDUINODIR defaults to ~/opt/arduino and

# then /usr/share/arduino, in that order.) You might be best to set this in

# your ~/.profile by adding something like this:

# export ARDUINODIR=~/somewhere/arduino-1.0

# You will also need to set BOARD to the type of Arduino you're building for.

# Type `make boards` for a list of acceptable values. You could set a default

# in your ~/.profile if you want, but it is suggested that you specify this at

# build time, especially if you work with different types of Arduino. For

# example:

# $ export BOARD=uno

# Note that if you're using the newer 1.5 Arduino software and the board you

# want to use is availble with different processors, you will also need to

# specify one. For example:

# $ export BOARD=mini.atmega328

# You may also need to set SERIALDEV if your Arduino is not detected correctly.

# $ make

# You may also need to set SERIALDEV if it is not detected correctly.

# The presence of a .ino (or .pde) file causes the arduino.mk to automatically

# determine values for SOURCES, TARGET and which libraries to pull-in to the

# build (although you can still override thius by setting LIBRARIES). Any .c,

# .cc and .cpp files in the project directory (or any "util" or "utility"

# subdirectories) are automatically included in the build and are scanned for

# Arduino libraries that have been #included. Note, there can only be one .ino

# (or .pde) file in a project directory and if you want to be compatible with

# the Arduino IDE, it should be called the same as the directory name.

# determine values for SOURCES, TARGET and LIBRARIES. Any .c, .cc and .cpp

# files in the project directory (or any "util" or "utility" subdirectories)

# are automatically included in the build and are scanned for Arduino libraries

# that have been #included. Note, there can only be one .ino (or .pde) file.

# Alternatively, if you want to manually specify build variables, create a

# Makefile that defines SOURCES and LIBRARIES and then includes arduino.mk.

# (You don't need to define TARGET). You can also specify the BOARD here, if

# the project has a specific one. Here is an example Makefile:

# (There is no need to define TARGET). Here is an example Makefile:

# SOURCES := main.cc other.cc

# LIBRARIES := EEPROM

# BOARD := pro5v

# Here is a complete list of environment variables that affect the build:

# Here is a complete list of configuration parameters:

# ARDUINODIR The directory where the Arduino software resides on your system.

# ARDUINODIR The path where the Arduino software is installed on your system.

# ARDUINOCONST The Arduino software version, as an integer, used to define the

# ARDUINO version constant. This defaults to 100 if undefined.

100

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

101

# based on where avrdude is. If set empty, no avrdude.conf is

102

# passed to avrdude (so the system default is used).

103

104

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

105

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

106

107

108

# when looking for the avr build tools. This defaults to PATH,

109

# followed by subdirectories in ARDUINODIR.

# ARDUINO version constant. This defaults to 100 if undefined.

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

# based on where the avrdude in use is. If empty, no avrdude.conf

# is passed to avrdude (to the system default is used).

# AVRTOOLSPATH A space-separated list of directories to search in order when

# looking for the avr build tools. This defaults to the system PATH

# followed by subdirectories in ARDUINODIR if undefined.

110

111

# BOARD Specify a target board type. Run `make boards` to see available

112

# board types. For Arduino 1.5, you will also need to specify a

113

# processor if the board supports multiple processors (see above).

114

115

# CPPFLAGS Specify any additional flags for the compiler. The usual flags,

116

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

# SERIALDEV The POSIX device name of the serial device that is the Arduino.
