# Sprinter Arduino Project Makefile
# 
# Makefile Based on:
# Arduino 0011 Makefile
# Arduino adaptation by mellis, eighthave, oli.keller
#
# This has been tested with Arduino 0022.
# 
# This makefile allows you to build sketches from the command line
# without the Arduino environment (or Java).
#
# Detailed instructions for using the makefile:
#
#  1. Modify the line containg "INSTALL_DIR" to point to the directory that
#     contains the Arduino installation (for example, under Mac OS X, this
#     might be /Applications/arduino-0012).
#
#  2. Modify the line containing "PORT" to refer to the filename
#     representing the USB or serial connection to your Arduino board
#     (e.g. PORT = /dev/tty.USB0).  If the exact name of this file
#     changes, you can use * as a wildcard (e.g. PORT = /dev/tty.usb*).
#
#  3. Set the line containing "MCU" to match your board's processor. 
#     Older one's are atmega8 based, newer ones like Arduino Mini, Bluetooth
#     or Diecimila have the atmega168.  If you're using a LilyPad Arduino,
#     change F_CPU to 8000000. If you are using Gen7 electronics, you
#     probably need to use 20000000. Either way, you must regenerate
#     the speed lookup table with create_speed_lookuptable.py.
#
#  4. Type "make" and press enter to compile/verify your program.
#
#  5. Type "make upload", reset your Arduino board, and press enter to
#     upload your program to the Arduino board.
