Firmware2/Marlin/Makefile

# Marlin Firmware Arduino Project Makefile
#
# Makefile Based on:
# Arduino 0011 Makefile
# Arduino adaptation by mellis, eighthave, oli.keller
# Marlin adaption by Daid
# Marlin 2.0 support and RELOC_WORKAROUND by @marcio-ao
#
# 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 containing "ARDUINO_INSTALL_DIR" to point to the directory that
#     contains the Arduino installation (for example, under Mac OS X, this
#     might be /Applications/Arduino.app/Contents/Resources/Java).
#
#  2. Modify the line containing "UPLOAD_PORT" to refer to the filename
#     representing the USB or serial connection to your Arduino board
#     (e.g. UPLOAD_PORT = /dev/tty.USB0).  If the exact name of this file
#     changes, you can use * as a wild card (e.g. UPLOAD_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.
#
# Note that all settings at the top of this file can be overriden from
# the command line with, for example, "make HARDWARE_MOTHERBOARD=71"
#
# To compile for RAMPS (atmega2560) with Arduino 1.6.9 at root/arduino you would use...
#
#   make ARDUINO_VERSION=10609 AVR_TOOLS_PATH=/root/arduino/hardware/tools/avr/bin/ \
#   HARDWARE_MOTHERBOARD=33 ARDUINO_INSTALL_DIR=/root/arduino
#
# To compile and upload simply add "upload" to the end of the line...
#
#   make ARDUINO_VERSION=10609 AVR_TOOLS_PATH=/root/arduino/hardware/tools/avr/bin/ \
#   HARDWARE_MOTHERBOARD=33 ARDUINO_INSTALL_DIR=/root/arduino upload
#
# If uploading doesn't work try adding the parameter "AVRDUDE_PROGRAMMER=wiring" or
# start upload manually (using stk500) like so:
#
#   avrdude -C /root/arduino/hardware/tools/avr/etc/avrdude.conf -v -p m2560 -c stk500 \
#   -U flash:w:applet/Marlin.hex:i -P /dev/ttyUSB0
#
# Or, try disconnecting USB to power down and then reconnecting before running avrdude.
