+# 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 macOS, 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. Set
+#     "PROG_MCU" as the AVR part name corresponding to "MCU". You can use the
+#     following command to get a list of correspondences: `avrdude -c alf -p x`
+#     Older boards 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 overridden 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=1200 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=1200 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.
+#
+
+# This defines the board to compile for (see boards.h for your board's ID)
