- # This is a general purpose makefile for use with Arduino hardware and
- # software. It works with the arduino-1.0 and later software releases. It
- # should work GNU/Linux and OS X. To download the latest version of this
- # makefile visit the following website where you can also find documentation on
- # it's use. (The following text can only really be considered a reference.)
- #
- # http://ed.am/dev/make/arduino-mk
- #
- # This makefile can be used as a drop-in replacement for the Arduino IDE's
- # build system. To use it, just 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:
- #
- # $ ln -s ~/src/arduino.mk Makefile
- #
- # The Arduino software (version 1.0 or later) 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.
- #
- # 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 path 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
- #
- # 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:
- #
- # $ export BOARD=uno
- # $ 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 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.
- #
- # Alternatively, if you want to manually specify build variables, create a
- # Makefile that defines SOURCES and LIBRARIES and then includes arduino.mk.
- # (There is no need to define TARGET). You can also specify the BOARD here, if
- # the project has a specific one. Here is an example Makefile:
- #
- # SOURCES := main.cc other.cc
- # LIBRARIES := EEPROM
- # BOARD := pro5v
- # include ~/src/arduino.mk
- #
- # Here is a complete list of configuration parameters:
- #
- # 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.
- #
- # AVRDUDECONF The avrdude.conf to use. If undefined, this defaults to a guess
- # based on where avrdude is. If set empty, no avrdude.conf is
- # passed to avrdude (so the system default is used).
- #
- # AVRDUDEFLAGS Specify any additional flags for avrdude. The usual flags,
- # required to build the project, will be appended to this.
- #
- # AVRTOOLSPATH A space-separated list of directories that is searched in order
- # when looking for the avr build tools. This defaults to PATH,
- # followed by subdirectories in ARDUINODIR.
- #
- # BOARD Specify a target board type. Run `make boards` to see available
- # board types.
- #
- # CPPFLAGS Specify any additional flags for the compiler. The usual flags,
- # required to build the project, will be appended to this.
- #
- # LINKFLAGS Specify any additional flags for the linker. The usual flags,
- # required to build the project, will be appended to this.
- #
- # LIBRARIES A list of Arduino libraries to build and include. This is set
- # automatically if a .ino (or .pde) is found.
- #
- # LIBRARYPATH A space-separated list of directories that is searched in order
- # when looking for Arduino libraries. This defaults to "libs",
- # "libraries" (in the project directory), then your sketchbook
- # "libraries" directory, then the Arduino libraries directory.
- #
- # SERIALDEV The POSIX device name of the serial device that is the Arduino.
- # If unspecified, an attempt is made to guess the name of a
- # connected Arduino's serial device, which may work in some cases.
- #
- # SOURCES A list of all source files of whatever language. The language
- # type is determined by the file extension. This is set
- # automatically if a .ino (or .pde) is found.
- #
- # TARGET The name of the target file. This is set automatically if a
- # .ino (or .pde) is found, but it is not necessary to set it
- # otherwise.
- #
- # This makefile also defines the following goals for use on the command line
- # when you run make:
- #
- # all This is the default if no goal is specified. It builds the
- # target.
- #
- # target Builds the target.
- #
- # upload Uploads the target (building it, as necessary) to an attached
- # Arduino.
- #
- # clean Deletes files created during the build.
- #
- # boards Display a list of available board names, so that you can set the
- # BOARD environment variable appropriately.
- #
- # monitor Start `screen` on the serial device. This is meant to be an
- # equivalent to the Arduino serial monitor.
- #
- # size Displays size information about the built target.
- #
- # bootloader Burns the bootloader for your board to it.
- #
- # <file> Builds the specified file, either an object file or the target,
- # from those that that would be built for the project.
