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. +#_______________________________________________________________________________ +# + +# default arduino software directory, check software exists +ifndef ARDUINODIR +ARDUINODIR := $(firstword $(wildcard ~/opt/arduino /usr/share/arduino \ + /Applications/Arduino.app/Contents/Resources/Java \ + $(HOME)/Applications/Arduino.app/Contents/Resources/Java)) +endif +ifeq "$(wildcard $(ARDUINODIR)/hardware/arduino/boards.txt)" "" +$(error ARDUINODIR is not set correctly; arduino software not found) +endif + +# default arduino version +ARDUINOCONST ?= 100 + +# default path for avr tools +AVRTOOLSPATH ?= $(subst :, , $(PATH)) $(ARDUINODIR)/hardware/tools \ + $(ARDUINODIR)/hardware/tools/avr/bin + +# default path to find libraries +LIBRARYPATH ?= libraries libs $(SKETCHBOOKDIR)/libraries $(ARDUINODIR)/libraries + +# default serial device to a poor guess (something that might be an arduino) +SERIALDEVGUESS := 0 +ifndef SERIALDEV +SERIALDEV := $(firstword $(wildcard \ + /dev/ttyACM? /dev/ttyUSB? /dev/tty.usbserial* /dev/tty.usbmodem*)) +SERIALDEVGUESS := 1 +endif + +# no board? +ifndef BOARD +ifneq "$(MAKECMDGOALS)" "boards" +ifneq "$(MAKECMDGOALS)" "clean" +$(error BOARD is unset.
