# 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
41

# The Arduino software (version 1.0 or later, including the new 1.5 BETA) is
46

47

48
# install arduino`. Otherwise, you can download the Arduino software manually
49
# from http://arduino.cc/. It is suggested that you install it at
50

52
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 directory where you unpacked it.
55
# (If unset, ARDUINODIR defaults to some sensible places). You could set this
56
# in your ~/.profile by adding something like this:
58
# export ARDUINODIR=~/somewhere/arduino-1.0.5
60
# 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.
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
54
# your ~/.profile by adding something like this:
56
# export ARDUINODIR=~/somewhere/arduino-1.0
58
# You will also need to set BOARD to the type of Arduino you're building for.
59
# Type `make boards` for a list of acceptable values. You could set a default
60
# in your ~/.profile if you want, but it is suggested that you specify this at
61
# build time, especially if you work with different types of Arduino. For
64
64
# $ export BOARD=uno
66
# Note that if you're using the newer 1.5 Arduino software and the board you
67
# want to use is availble with different processors, you will also need to
68
# specify one. For example:
70
# $ export BOARD=mini.atmega328
72
# You may also need to set SERIALDEV if your Arduino is not detected correctly.

# The presence of a .ino (or .pde) file causes the arduino.mk to automatically
75
# determine values for SOURCES, TARGET and which libraries to pull-in to the
76
# build (although you can still override thius by setting LIBRARIES). Any .c,
77
# .cc and .cpp files in the project directory (or any "util" or "utility"
78
# subdirectories) are automatically included in the build and are scanned for
79
# Arduino libraries that have been #included. Note, there can only be one .ino
80
# (or .pde) file in a project directory and if you want to be compatible with
81
# the Arduino IDE, it should be called the same as the directory name.

75
# Alternatively, if you want to manually specify build variables, create a
84
76
