It works with the arduino-1.0 software release. To download the # latest version of this makefile, visit the following website, where you can # also find more information and documentation on it's use. The following text # can only really be considered a reference to it's use. # # 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, 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) 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, 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 # $ 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. # # 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). Here is an example Makefile: # # SOURCES := main.cc other.cc # LIBRARIES := EEPROM # 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 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. # # BOARD Specify a target board type. Run `make boards` to see available # board types. # # LIBRARIES A list of Arduino libraries to build and include. This is set # automatically if a .ino (or .pde) is found. # # SERIALDEV The unix device name of the serial device that is the Arduino. # If unspecified, an attempt is made to determine the name of a # connected Arduino's serial device. # # 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 last built target 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 bulit target. # # 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 $(wildcard ~/opt/arduino /usr/share/arduino)) endif ifeq "$(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 ifndef AVRTOOLSPATH AVRTOOLSPATH := $(subst :, , $(PATH)) AVRTOOLSPATH += $(ARDUINODIR)/hardware/tools AVRTOOLSPATH += $(ARDUINODIR)/hardware/tools/avr/bin endif # auto mode?
