+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team at [marlinfirmware@github.com](mailto:marlinfirmware@github.com). All complaints will be reviewed and investigated and will result in a response that is deemed necessary and appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4, available at [https://contributor-covenant.org/version/1/4][version]

+## Code of Conduct
+
+This project and everyone participating in it is governed by the [Marlin Code of Conduct](code_of_conduct.md). By participating, you are expected to uphold this code. Please report unacceptable behavior to [marlinfirmware@github.com](mailto:marlinfirmware@github.com).
+
+## I don't want to read this whole thing I just have a question!!!
+
+> **Note:** Please don't file an issue to ask a question. You'll get faster results by using the resources below.
+
+We have a Message Board and a Facebook group where our knowledgable user community can provide helpful advice if you have questions.
+
+* [Marlin RepRap forum](https://reprap.org/forum/list.php?415)

+
+If chat is more your speed, you can join the MarlinFirmware Discord server:
+
+* Use the link https://discord.gg/n5NJ59y to join up as a General User.
+* Even though our Discord is pretty active, it may take a while for community members to respond — please be patient!
+* Use the `#general` channel for general questions or discussion about Marlin.
+* Other channels exist for certain topics or are limited to Patrons. Check the channel list.
+
+## How Can I Contribute?
+
+### Reporting Bugs
+
+This section guides you through submitting a Bug Report for Marlin. Following these guidelines helps maintainers and the community understand your report, reproduce the behavior, and find related reports.
+
+Before creating a Bug Report, please test the "nightly" development branch, as you might find out that you don't need to create one. When you are creating a Bug Report, please [include as many details as possible](#how-do-i-submit-a-good-bug-report). Fill out [the required template](issue_template.md), the information it asks for helps us resolve issues faster.
+
+> **Note:** Regressions can happen. If you find a **Closed** issue that seems like your issue, go ahead and open a new issue and include a link to the original issue in the body of your new one. All you need to create a link is the issue number, preceded by #. For example, #8888.
+
+#### How Do I Submit A (Good) Bug Report?
+
+Bugs are tracked as [GitHub issues](https://guides.github.com/features/issues/). Use the New Issue button to create an issue and provide the following information by filling in [the template](issue_template.md).
+
+Explain the problem and include additional details to help maintainers reproduce the problem:
+
+* **Use a clear and descriptive title** for the issue to identify the problem.
+* **Describe the exact steps which reproduce the problem** in as many details as possible. For example, start by explaining how you started Marlin, e.g. which command exactly you used in the terminal, or how you started Marlin otherwise. When listing steps, **don't just say what you did, but explain how you did it**. For example, if you moved the cursor to the end of a line, explain if you used the mouse, or a keyboard shortcut or an Marlin command, and if so which one?
+* **Provide specific examples to demonstrate the steps**. Include links to files or GitHub projects, or copy/pasteable snippets, which you use in those examples. If you're providing snippets or log output in the issue, use [Markdown code blocks](https://help.github.com/articles/markdown-basics/#multiple-lines).
+* **Describe the behavior you observed after following the steps** and point out what exactly is the problem with that behavior.
+* **Explain which behavior you expected to see instead and why.**
+* **Include detailed log output** especially for probing and leveling. See below for usage of `DEBUG_LEVELING_FEATURE`.
+* **Include screenshots, links to videos, etc.** which clearly demonstrate the problem.
+* **Include G-code** (if relevant) that reliably causes the problem to show itself.
+* **If the problem wasn't triggered by a specific action**, describe what you were doing before the problem happened and share more information using the guidelines below.
+
+Provide more context:
+
+* **Can you reproduce the problem with a minimum of options enabled?**
+* **Did the problem start happening recently** (e.g. after updating to a new version of Marlin) or was this always a problem?
+* If the problem started happening recently, **can you reproduce the problem in an older version of Marlin?** What's the most recent version in which the problem doesn't happen? You can download older versions of Marlin from [the releases page](https://github.com/MarlinFirmware/Marlin/releases).
+* **Can you reliably reproduce the issue?** If not, provide details about how often the problem happens and under which conditions it normally happens.
+
+Include details about your configuration and environment:
+
+* **Which version of Marlin are you using?** Marlin's exact version and build date can be seen in the startup message when a host connects to Marlin, or in the LCD Info menu (if enabled).
+* **What kind of 3D Printer and electronics are you using**?
+* **What kind of add-ons (probe, filament sensor) do you have**?
+* **Include your Configuration files.** Make a ZIP file containing `Configuration.h` and `Configuration_adv.h` and drop it on your reply.
+
+### Suggesting Features or Changes
+
+This section guides you through submitting a suggestion for Marlin, including completely new features and minor improvements to existing functionality. Following these guidelines helps maintainers and the community understand your suggestion and find related suggestions.
+
+Before creating a suggestion, please check [this list](#before-submitting-a-suggestion) as you might find out that you don't need to create one. When you are creating an enhancement suggestion, please [include as many details as possible](#how-do-i-submit-a-good-enhancement-suggestion). Fill in [the template](issue_template.md), including the steps that you imagine you would take if the feature you're requesting existed.
+
+#### Before Submitting a Feature Request
+
+* **Check the [Marlin website](https://marlinfw.org/)** for tips — you might discover that the feature is already included. Most importantly, check if you're using [the latest version of Marlin](https://github.com/MarlinFirmware/Marlin/releases) and if you can get the desired behavior by changing [Marlin's config settings](https://marlinfw.org/docs/configuration/configuration.html).
+* **Perform a [cursory search](https://github.com/MarlinFirmware/Marlin/issues?q=is%3Aissue)** to see if the enhancement has already been suggested. If it has, add a comment to the existing issue instead of opening a new one.
+
+#### How Do I Submit A (Good) Feature Request?
+
+Feature Requests are tracked as [GitHub issues](https://guides.github.com/features/issues/). Please follow these guidelines in your request:
+
+* **Use a clear and descriptive title** for the issue to identify the suggestion.
+* **Provide a step-by-step description of the requested feature** in as much detail as possible.
+* **Provide specific examples to demonstrate the steps**.
+* **Describe the current behavior** and **explain which behavior you expected to see instead** and why.
+* **Include screenshots and links to videos** which demonstrate the feature or point out the part of Marlin to which the request is related.
+* **Explain why this feature would be useful** to most Marlin users.
+* **Name other firmwares that have this feature, if any.**
+
+### Your First Code Contribution
+
+Unsure where to begin contributing to Marlin? You can start by looking through these `good-first-issue` and `help-wanted` issues:
+
+* [Beginner issues][good-first-issue] - issues which should only require a few lines of code, and a test or two.
+* [Help Wanted issues][help-wanted] - issues which should be a bit more involved than `beginner` issues.
+
+### Pull Requests
+
+Pull Requests should always be targeted to working branches (e.g., `bugfix-1.1.x` and/or `bugfix-2.0.x`) and never to release branches (e.g., `1.1.x`). If this is your first Pull Request, please read our [Guide to Pull Requests](https://marlinfw.org/docs/development/getting_started_pull_requests.html) and Github's [Pull Request](https://help.github.com/articles/creating-a-pull-request/) documentation.
+
+* Fill in [the required template](pull_request_template.md).
+* Don't include issue numbers in the PR title.
+* Include pictures, diagrams, and links to videos in your Pull Request to demonstrate your changes, if needed.
+* Follow the [Coding Standards](https://marlinfw.org/docs/development/coding_standards.html) posted on our website.
+* Document new code with clear and concise comments.
+* End all files with a newline.
+
+## Styleguides
+
+### Git Commit Messages
+
+* Use the present tense ("Add feature" not "Added feature").
+* Use the imperative mood ("Move cursor to..." not "Moves cursor to...").
+* Limit the first line to 72 characters or fewer.
+* Reference issues and Pull Requests liberally after the first line.
+
+### C++ Coding Standards
+
+* Please read and follow the [Coding Standards](https://marlinfw.org/docs/development/coding_standards.html) posted on our website. Failure to follow these guidelines will delay evaluation and acceptance of Pull Requests.
+
+### Documentation
+
+* Guidelines for documentation are still under development. In-general, be clear, concise, and to-the-point.

+# 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"
+#

+================================================================================
+
+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

+This directory is intended for the project specific (private) libraries.
+PlatformIO will compile them to static libraries and link to executable file.
+
+The source code of each library should be placed in separate directory, like
+"lib/private_lib/[here are source files]".
+
+For example, see how can be organized `Foo` and `Bar` libraries:
+
+|--lib
+| |--Bar
+| | |--docs
+| | |--examples
+| | |--src
+| | |- Bar.c
+| | |- Bar.h
+| |--Foo
+| | |- Foo.c
+| | |- Foo.h
+| |- readme.txt --> THIS FILE
+|- platformio.ini
+|--src
+ |- main.c
+
+Then in `src/main.c` you should use:
+
+#include
+#include
+
+// rest H/C/CPP code
+
+PlatformIO will find your libraries automatically, configure preprocessor's
+include paths and build them.

+/**
+ * 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.

+ * - is not in port/pin order
+ * - typically a variant will only assign Ard_num to port/pins that are actually used
+ * Index - M43 counter - only used to get Ard_num
+ * x - a parameter/argument used to search the pin_array to try to find a signal name
+ * associated with a Ard_num
+ * Port_pin - port number and pin number for use with CPU registers and printing reports
+ *
+ * Since M43 uses digitalRead and digitalWrite commands, only the Port_pins with an Ard_num
+ * are accessed and/or displayed.
+ *
+ * Three arrays are used.
+ *
+ * digitalPin[] is provided by the platform. It consists of the Port_pin numbers in
+ * Arduino pin number order.
+ *
+ * pin_array is a structure generated by the pins/pinsDebug.h header file. It is generated by
+ * the preprocessor. Only the signals associated with enabled options are in this table.
+ * It contains:
+ * - name of the signal
+ * - the Ard_num assigned by the pins_YOUR_BOARD.h file using the platform defines.
+ * EXAMPLE: "#define KILL_PIN PB1" results in Ard_num of 57. 57 is then used as the
+ * argument to digitalPinToPinName(IO) to get the Port_pin number
+ * - if it is a digital or analog signal. PWMs are considered digital here.
+ *
+ * pin_xref is a structure generated by this header file. It is generated by the
+ * preprocessor. It is in port/pin order. It contains just the port/pin numbers defined by the
+ * platform for this variant.
+ * - Ard_num
+ * - printable version of Port_pin
+ *
+ * Routines with an "x" as a parameter/argument are used to search the pin_array to try to
+ * find a signal name associated with a port/pin.
+ *
+ * NOTE - the Arduino pin number is what is used by the M42 command, NOT the port/pin for that
+ * signal. The Arduino pin number is listed by the M43 I command.
