# Makefile for building Arduino projects outside of the Arduino environment
#
# This makefile should be included into a per-project Makefile of the following
# form:
#
# ----------
# BOARD = mega
# PORT = /dev/term/0
# INC_DIRS = ../common
# LIB_DIRS = ../libraries/Task ../../libraries/VirtualWire
# include ../../Makefile.master
# ----------
#
# Where:
# BOARD : Arduino board type, from $(ARD_HOME)/hardware/boards.txt
# PORT : USB port
# INC_DIRS : List pf directories containing header files
# LIB_DIRS : List of directories containing library source
#
# Before using this Makefile you can adjust the following macros to suit
# your environment, either by editing this file directly or by defining them in
# the Makefile that includes this one, in which case they will override the
# definitions below:
# ARD_REV : arduino software revision, e.g. 0017, 0018
# ARD_HOME : installation directory of the Arduino software.
# ARD_BIN : location of compiler binaries
# AVRDUDE : location of avrdude executable
# AVRDUDE_CONF : location of avrdude configuration file
# PROGRAMMER : avrdude programmer type
# MON_CMD : serial monitor command
# MON_SPEED : serial monitor speed
#
# Global configuration.
