#
# This is a general purpose makefile for use with TI's MSP430 Launchpad hardware and
# and Energia Arduino clone software
#
# This makefile can be used as a drop-in replacement for the Energia IDE's
#
# The Energia software is required.  If you are using
#
#   export ENERGIADIR=~/somewhere/energia
#
# 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 ENERGIABOARD=lpmsp430g2553
#   $ 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/energia.mk
#
# Here is a complete list of configuration parameters:
#
# ENERGIACONST The Energia/Arduino software version, as an integer, used to define the
#              ARDUINO/ENERGIA version constant. This defaults to 100 if undefined.
#
#
#
# ENERGIADIR   The path where the Arduino software is installed on your system.
#
#
# ENERGIABOARD        Specify a target board type.  Run `make boards` to see available
#              board types.
#
# LIBRARIES    A list of Energia 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 Launchpad.
#
# 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.
#
# <file>       Builds the specified file, either an object file or the target,
#              from those that that would be built for the project.
