+# 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.

+
+================================================================================
+
+Greetings! Thank you for choosing Marlin 2 as your 3D printer firmware.
+
+To configure Marlin you must edit Configuration.h and Configuration_adv.h
+located in the root 'Marlin' folder. Check our Configurations repository to
+see if there's a more suitable starting-point for your specific hardware.
+
+Before diving in, we recommend the following essential links:
+
+Marlin Firmware Official Website
+
+ - https://marlinfw.org/
+ The official Marlin Firmware website contains the most up-to-date
+ documentation. Contributions are always welcome!
+
+Configuration
+
+ - https://github.com/MarlinFirmware/Configurations
+ Example configurations for several printer models.
+
+ - https://www.youtube.com/watch?v=3gwWVFtdg-4
+ A good 20-minute overview of Marlin configuration by Tom Sanladerer.
+ (Applies to Marlin 1.0.x, so Jerk and Acceleration should be halved.)
+ Also... https://www.google.com/search?tbs=vid%3A1&q=configure+marlin
+
+ - https://marlinfw.org/docs/configuration/configuration.html
+ Marlin's configuration options are explained in more detail here.
+
+Getting Help
+
+ - https://reprap.org/forum/list.php?415
+ The Marlin Discussion Forum is a great place to get help from other Marlin
+ users who may have experienced similar issues to your own.
+
+ - https://github.com/MarlinFirmware/Marlin/issues
+ With a free GitHub account you can provide us with feedback, bug reports,
+ and feature requests via the Marlin Issue Queue.
+
+Contributing
+
+ - https://marlinfw.org/docs/development/contributing.html
+ If you'd like to contribute to Marlin, read this first!

+/**
+ * A servo is activated by creating an instance of the Servo class passing the desired pin to the attach() method.
+ * The servos are pulsed in the background using the value most recently written using the write() method
+ *
+ * Note that analogWrite of PWM on pins associated with the timer are disabled when the first servo is attached.
+ * Timers are seized as needed in groups of 12 servos - 24 servos use two timers, 48 servos will use four.
+ *
+ * The methods are:
+ *
+ * Servo - Class for manipulating servo motors connected to Arduino pins.
+ *
+ * attach(pin) - Attach a servo motor to an i/o pin.
+ * attach(pin, min, max) - Attach to a pin, setting min and max values in microseconds
+ * Default min is 544, max is 2400
+ *
+ * write() - Set the servo angle in degrees. (Invalid angles —over MIN_PULSE_WIDTH— are treated as µs.)
+ * writeMicroseconds() - Set the servo pulse width in microseconds.
+ * move(pin, angle) - Sequence of attach(pin), write(angle), safe_delay(servo_delay[servoIndex]).
+ * With DEACTIVATE_SERVOS_AFTER_MOVE it detaches after servo_delay[servoIndex].
+ * read() - Get the last-written servo pulse width as an angle between 0 and 180.
+ * readMicroseconds() - Get the last-written servo pulse width in microseconds.
+ * attached() - Return true if a servo is attached.
+ * detach() - Stop an attached servo from pulsing its i/o pin.
