-Build CircuitPython in a Github-Devcontainer
-============================================
-
-To build CircuitPython within a Github-Devcontainer, you need to perform
-the following steps.
-
-  1. checkout the code to a devcontainer
-
-    - click on the green "<> Code"-button
-    - select the Codespaces-tab
-    - choose "+ new with options..." from the "..."-menu
-    - in the following screen select the branch and then
-    - select ".devcontainer/cortex-m/devcontainer.json" instead
-      of "Default Codespaces configuration"
-    - update region as necessary
-    - finally, click on the green "Create codespace" button
-
-  2. Your codespace is created. Cloning the images is quite fast, but
-     preparing it for CircuitPython-development takes about 10 minutes.
-     Note that this is a one-time task.
-
-  3. During creation, you can run the command
-     `tail -f /workspaces/.codespaces/.persistedshare/creation.log`
-     to see what is going on.
-
-  4. To actually build CircuitPython, run
-
-         cd ports/raspberrypi
-         make -j $(nproc) BOARD=whatever TRANSLATION=xx_XX
-
-     This takes about 2m40s.

-# Building CircuitPython
-
-Welcome to CircuitPython!
-
-This document is a quick-start guide only.
-
-Detailed guides on how to build CircuitPython can be found in the Adafruit Learn system at
-https://learn.adafruit.com/building-circuitpython/
-
-## Setup
-
-Please ensure you set up your build environment appropriately, as per the guide.  You will need:
-
-* Linux: https://learn.adafruit.com/building-circuitpython/linux
-* MacOS: https://learn.adafruit.com/building-circuitpython/macos
-* Windows Subsystem for Linux (WSL): https://learn.adafruit.com/building-circuitpython/windows-subsystem-for-linux
-
-### Submodules
-
-This project has a bunch of git submodules.  You will need to update them regularly.
-
-In the root folder of the CircuitPython repository, execute the following:
-
-    make fetch-all-submodules
-
-Or, in the ports directory for the particular port you are building, do:
-
-    make fetch-port-submodules
-
-### Required Python Packages
-
-Failing to install these will prevent from properly building.
-
-    pip3 install -r requirements-dev.txt
-
-If you run into an error installing minify_html, you may need to install `rust`.
-
-### mpy-cross
-
-As part of the build process, mpy-cross is needed to compile .py files into .mpy files.
-To compile (or recompile) mpy-cross:
-
-    make -C mpy-cross
-
-## Building
-
-There a number of ports of CircuitPython!  To build for your board, change to the appropriate ports directory and build.
-
-Examples:
-
-    cd ports/atmel-samd
-    make BOARD=circuitplayground_express
-
-    cd ports/nrf
-    make BOARD=circuitplayground_bluefruit
-
-If you aren't sure what boards exist, have a peek in the boards subdirectory of your port.
-If you have a fast computer with many cores, consider adding `-j` to your build flags, such as `-j17` on
-a 6-core 12-thread machine.
-
-## Testing
-
-If you are working on changes to the core language, you might find it useful to run the test suite.
-The test suite in the top level `tests` directory.  It needs the unix port to run.
-
-    cd ports/unix
-    make axtls
-    make micropython
-
-Then you can run the test suite:
-
-    cd ../../tests
-    ./run-tests.py
-
-A successful run will say something like
-
-    676 tests performed (19129 individual testcases)
-    676 tests passed
-    30 tests skipped: buffered_writer builtin_help builtin_range_binop class_delattr_setattr cmd_parsetree extra_coverage framebuf1 framebuf16 framebuf2 framebuf4 framebuf8 framebuf_subclass mpy_invalid namedtuple_asdict non_compliant resource_stream schedule sys_getsizeof urandom_extra ure_groups ure_span ure_sub ure_sub_unmatched vfs_basic vfs_fat_fileio1 vfs_fat_fileio2 vfs_fat_more vfs_fat_oldproto vfs_fat_ramdisk vfs_userfs
-
-## Debugging
-
-The easiest way to debug CircuitPython on hardware is with a JLink device, JLinkGDBServer, and an appropriate GDB.
-Instructions can be found at https://learn.adafruit.com/debugging-the-samd21-with-gdb
-
-If using JLink, you'll need both the `JLinkGDBServer` and `arm-none-eabi-gdb` running.
-
-Example:
-
-    JLinkGDBServer -if SWD -device ATSAMD51J19
-    arm-none-eabi-gdb build-metro_m4_express/firmware.elf -iex "target extended-remote :2331"
-
-If your port/build includes `arm-none-eabi-gdb-py`, consider using it instead, as it can be used for better register
-debugging with https://github.com/bnahill/PyCortexMDebug
-
-## Code Quality Checks
-
-We apply code quality checks using pre-commit.  Install pre-commit once per system with
-
-    python3 -mpip install pre-commit
-
-Activate it once per git clone with
-
-    pre-commit install
-
-Pre-commit also requires some additional programs to be installed through your package manager:
-
- * Standard Unix tools such as make, find, etc
- * The gettext package, any modern version
- * uncrustify version 0.71 (0.72 is also tested and OK; 0.75 is not OK)
-
-Each time you create a git commit, the pre-commit quality checks will be run.  You can also run them e.g., with `pre-commit run foo.c` or `pre-commit run --all` to run on all files whether modified or not.
-
-Some pre-commit quality checks require your active attention to resolve, others (such as the formatting checks of uncrustify) are made automatically and must simply be incorporated into your code changes by committing them.

+# Contributor Covenant Code of Conduct
 
 ## Our Pledge
 
 In the interest of fostering an open and welcoming environment, we as
-contributors and leaders pledge to making participation in our project and
+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 or type of
-experience, education, socio-economic status, nationality, personal appearance,
-race, religion, or sexual identity and orientation.
+size, disability, ethnicity, gender identity and expression, level of experience,
+nationality, personal appearance, race, religion, or sexual identity and
+orientation.
 
 ## Our Standards
 
-We are committed to providing a friendly, safe and welcoming environment for
-all.
-
 Examples of behavior that contributes to creating a positive environment
 include:
 
-* Be kind and courteous to others
 * Using welcoming and inclusive language
 * Being respectful of differing viewpoints and experiences
-* Collaborating with other community members
 * 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 sexual attention or advances
-* The use of inappropriate images, including in a community member's avatar
-* The use of inappropriate language, including in a community member's nickname
-* Any spamming, flaming, baiting or other attention-stealing behavior
-* Excessive or unwelcome helping; answering outside the scope of the question
-  asked
+* The use of sexualized language or imagery and unwelcome sexual attention or
+advances
 * Trolling, insulting/derogatory comments, and personal or political attacks
-* Promoting or spreading disinformation, lies, or conspiracy theories against
-  a person, group, organisation, project, or community
 * 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
-
-The goal of the standards and moderation guidelines outlined here is to build
-and maintain a respectful community. We ask that you don’t just aim to be
-"technically unimpeachable", but rather try to be your best self.
-
-We value many things beyond technical expertise, including collaboration and
-supporting others within our community. Providing a positive experience for
-other community members can have a much more significant impact than simply
-providing the correct answer.
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
 
 ## Our Responsibilities
 
-Project leaders are responsible for clarifying the standards of acceptable
+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 leaders have the right and responsibility to remove, edit, or
-reject messages, comments, commits, code, issues, and other contributions
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
 that are not aligned to this Code of Conduct, or to ban temporarily or
-permanently any community member for other behaviors that they deem
-inappropriate, threatening, offensive, or harmful.
-
-## Moderation
-
-Instances of behaviors that violate the Adafruit Community Code of Conduct
-may be reported by any member of the community. Community members are
-encouraged to report these situations, including situations they witness
-involving other community members.
-
-You may report in the following ways:
-
-In any situation, you may send an email to <support@adafruit.com>.
-
-On the Adafruit Discord, you may send an open message from any channel
-to all Community Moderators by tagging @community moderators. You may
-also send an open message from any channel, or a direct message to
-@kattni#1507, @tannewt#4653, @danh#1614, @cater#2442,
-@sommersoft#0222, @Mr. Certainly#0472 or @Andon#8175.
-
-Email and direct message reports will be kept confidential.
-
-In situations on Discord where the issue is particularly egregious, possibly
-illegal, requires immediate action, or violates the Discord terms of service,
-you should also report the message directly to Discord.
-
-These are the steps for upholding our community’s standards of conduct.
-
-1. Any member of the community may report any situation that violates the
-Adafruit Community Code of Conduct. All reports will be reviewed and
-investigated.
-2. If the behavior is an egregious violation, the community member who
-committed the violation may be banned immediately, without warning.
-3. Otherwise, moderators will first respond to such behavior with a warning.
-4. Moderators follow a soft "three strikes" policy - the community member may
-be given another chance, if they are receptive to the warning and change their
-behavior.
-5. If the community member is unreceptive or unreasonable when warned by a
-moderator, or the warning goes unheeded, they may be banned for a first or
-second offense. Repeated offenses will result in the community member being
-banned.
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
 
 ## Scope
 
-This Code of Conduct and the enforcement policies listed above apply to all
-Adafruit Community venues. This includes but is not limited to any community
-spaces (both public and private), the entire Adafruit Discord server, and
-Adafruit GitHub repositories. Examples of Adafruit Community spaces include
-but are not limited to meet-ups, audio chats on the Adafruit Discord, or
-interaction at a conference.
-
 This Code of Conduct applies both within project spaces and in public spaces
-when an individual is representing the project or its community. As a community
-member, you are representing our community, and are expected to behave
-accordingly.
+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 support@adafruit.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.

-Using Creative Commons Public Licenses
-
-Creative Commons public licenses provide a standard set of terms and conditions
-that creators and other rights holders may use to share original works of
-authorship and other material subject to copyright and certain other rights
-specified in the public license below. The following considerations are for
-informational purposes only, are not exhaustive, and do not form part of our
-licenses.
-
-Considerations for licensors: Our public licenses are intended for use by
-those authorized to give the public permission to use material in ways otherwise
-restricted by copyright and certain other rights. Our licenses are irrevocable.
-Licensors should read and understand the terms and conditions of the license
-they choose before applying it. Licensors should also secure all rights necessary
-before applying our licenses so that the public can reuse the material as
-expected. Licensors should clearly mark any material not subject to the license.
-This includes other CC-licensed material, or material used under an exception
-or limitation to copyright. More considerations for licensors : wiki.creativecommons.org/Considerations_for_licensors
-
-Considerations for the public: By using one of our public licenses, a licensor
-grants the public permission to use the licensed material under specified
-terms and conditions. If the licensor's permission is not necessary for any
-reason–for example, because of any applicable exception or limitation to copyright–then
-that use is not regulated by the license. Our licenses grant only permissions
-under copyright and certain other rights that a licensor has authority to
-grant. Use of the licensed material may still be restricted for other reasons,
-including because others have copyright or other rights in the material. A
-licensor may make special requests, such as asking that all changes be marked
-or described. Although not required by our licenses, you are encouraged to
-respect those requests where reasonable. More considerations for the public
-: wiki.creativecommons.org/Considerations_for_licensees Creative Commons Attribution

-
-By exercising the Licensed Rights (defined below), You accept and agree to
-be bound by the terms and conditions of this Creative Commons Attribution
-4.0 International Public License ("Public License"). To the extent this Public
-License may be interpreted as a contract, You are granted the Licensed Rights
-in consideration of Your acceptance of these terms and conditions, and the
-Licensor grants You such rights in consideration of benefits the Licensor
-receives from making the Licensed Material available under these terms and
-conditions.
-
-Section 1 – Definitions.
-
-a. Adapted Material means material subject to Copyright and Similar Rights
-that is derived from or based upon the Licensed Material and in which the
-Licensed Material is translated, altered, arranged, transformed, or otherwise
-modified in a manner requiring permission under the Copyright and Similar
-Rights held by the Licensor. For purposes of this Public License, where the
-Licensed Material is a musical work, performance, or sound recording, Adapted
-Material is always produced where the Licensed Material is synched in timed
-relation with a moving image.
-
-b. Adapter's License means the license You apply to Your Copyright and Similar
-Rights in Your contributions to Adapted Material in accordance with the terms
-and conditions of this Public License.
-
-c. Copyright and Similar Rights means copyright and/or similar rights closely
-related to copyright including, without limitation, performance, broadcast,
-sound recording, and Sui Generis Database Rights, without regard to how the
-rights are labeled or categorized. For purposes of this Public License, the
-rights specified in Section 2(b)(1)-(2) are not Copyright and Similar Rights.
-
-d. Effective Technological Measures means those measures that, in the absence
-of proper authority, may not be circumvented under laws fulfilling obligations
-under Article 11 of the WIPO Copyright Treaty adopted on December 20, 1996,
-and/or similar international agreements.
-
-e. Exceptions and Limitations means fair use, fair dealing, and/or any other
-exception or limitation to Copyright and Similar Rights that applies to Your
-use of the Licensed Material.
-
-f. Licensed Material means the artistic or literary work, database, or other
-material to which the Licensor applied this Public License.
-
-g. Licensed Rights means the rights granted to You subject to the terms and
-conditions of this Public License, which are limited to all Copyright and
-Similar Rights that apply to Your use of the Licensed Material and that the
-Licensor has authority to license.
-
-h. Licensor means the individual(s) or entity(ies) granting rights under this
-Public License.
-
-i. Share means to provide material to the public by any means or process that
-requires permission under the Licensed Rights, such as reproduction, public
-display, public performance, distribution, dissemination, communication, or
-importation, and to make material available to the public including in ways
-that members of the public may access the material from a place and at a time
-individually chosen by them.
-
-j. Sui Generis Database Rights means rights other than copyright resulting
-from Directive 96/9/EC of the European Parliament and of the Council of 11
-March 1996 on the legal protection of databases, as amended and/or succeeded,
-as well as other essentially equivalent rights anywhere in the world.
-
-k. You means the individual or entity exercising the Licensed Rights under
-this Public License. Your has a corresponding meaning.
-
-Section 2 – Scope.
-
-   a. License grant.
-
-1. Subject to the terms and conditions of this Public License, the Licensor
-hereby grants You a worldwide, royalty-free, non-sublicensable, non-exclusive,
-irrevocable license to exercise the Licensed Rights in the Licensed Material
-to:
-
-         A. reproduce and Share the Licensed Material, in whole or in part; and
-
-         B. produce, reproduce, and Share Adapted Material.
-
-2. Exceptions and Limitations. For the avoidance of doubt, where Exceptions
-and Limitations apply to Your use, this Public License does not apply, and
-You do not need to comply with its terms and conditions.
-
-      3. Term. The term of this Public License is specified in Section 6(a).
-
-4. Media and formats; technical modifications allowed. The Licensor authorizes
-You to exercise the Licensed Rights in all media and formats whether now known
-or hereafter created, and to make technical modifications necessary to do
-so. The Licensor waives and/or agrees not to assert any right or authority
-to forbid You from making technical modifications necessary to exercise the
-Licensed Rights, including technical modifications necessary to circumvent
-Effective Technological Measures. For purposes of this Public License, simply
-making modifications authorized by this Section 2(a)(4) never produces Adapted
-Material.
-
-      5. Downstream recipients.
-
-A. Offer from the Licensor – Licensed Material. Every recipient of the Licensed
-Material automatically receives an offer from the Licensor to exercise the
-Licensed Rights under the terms and conditions of this Public License.
-
-B. No downstream restrictions. You may not offer or impose any additional
-or different terms or conditions on, or apply any Effective Technological
-Measures to, the Licensed Material if doing so restricts exercise of the Licensed
-Rights by any recipient of the Licensed Material.
-
-6. No endorsement. Nothing in this Public License constitutes or may be construed
-as permission to assert or imply that You are, or that Your use of the Licensed
-Material is, connected with, or sponsored, endorsed, or granted official status
-by, the Licensor or others designated to receive attribution as provided in
-Section 3(a)(1)(A)(i).
-
-   b. Other rights.
-
-1. Moral rights, such as the right of integrity, are not licensed under this
-Public License, nor are publicity, privacy, and/or other similar personality
-rights; however, to the extent possible, the Licensor waives and/or agrees
-not to assert any such rights held by the Licensor to the limited extent necessary
-to allow You to exercise the Licensed Rights, but not otherwise.
-
-2. Patent and trademark rights are not licensed under this Public License.
-
-3. To the extent possible, the Licensor waives any right to collect royalties
-from You for the exercise of the Licensed Rights, whether directly or through
-a collecting society under any voluntary or waivable statutory or compulsory
-licensing scheme. In all other cases the Licensor expressly reserves any right
-to collect such royalties.
-
-Section 3 – License Conditions.
-
-Your exercise of the Licensed Rights is expressly made subject to the following
-conditions.
-
-   a. Attribution.
-
-1. If You Share the Licensed Material (including in modified form), You must:
-
-A. retain the following if it is supplied by the Licensor with the Licensed
-Material:
-
-i. identification of the creator(s) of the Licensed Material and any others
-designated to receive attribution, in any reasonable manner requested by the
-Licensor (including by pseudonym if designated);
-
-            ii. a copyright notice;
-
-            iii. a notice that refers to this Public License;
-
-            iv. a notice that refers to the disclaimer of warranties;
-
-v. a URI or hyperlink to the Licensed Material to the extent reasonably practicable;
-
-B. indicate if You modified the Licensed Material and retain an indication
-of any previous modifications; and
-
-C. indicate the Licensed Material is licensed under this Public License, and
-include the text of, or the URI or hyperlink to, this Public License.
-
-2. You may satisfy the conditions in Section 3(a)(1) in any reasonable manner
-based on the medium, means, and context in which You Share the Licensed Material.
-For example, it may be reasonable to satisfy the conditions by providing a
-URI or hyperlink to a resource that includes the required information.
-
-3. If requested by the Licensor, You must remove any of the information required
-by Section 3(a)(1)(A) to the extent reasonably practicable.
-
-4. If You Share Adapted Material You produce, the Adapter's License You apply
-must not prevent recipients of the Adapted Material from complying with this
-Public License.
-
-Section 4 – Sui Generis Database Rights.
-
-Where the Licensed Rights include Sui Generis Database Rights that apply to
-Your use of the Licensed Material:
-
-a. for the avoidance of doubt, Section 2(a)(1) grants You the right to extract,
-reuse, reproduce, and Share all or a substantial portion of the contents of
-the database;
-
-b. if You include all or a substantial portion of the database contents in
-a database in which You have Sui Generis Database Rights, then the database
-in which You have Sui Generis Database Rights (but not its individual contents)
-is Adapted Material; and
-
-c. You must comply with the conditions in Section 3(a) if You Share all or
-a substantial portion of the contents of the database.
-
-For the avoidance of doubt, this Section 4 supplements and does not replace
-Your obligations under this Public License where the Licensed Rights include
-other Copyright and Similar Rights.
-
-Section 5 – Disclaimer of Warranties and Limitation of Liability.
-
-a. Unless otherwise separately undertaken by the Licensor, to the extent possible,
-the Licensor offers the Licensed Material as-is and as-available, and makes
-no representations or warranties of any kind concerning the Licensed Material,
-whether express, implied, statutory, or other. This includes, without limitation,
-warranties of title, merchantability, fitness for a particular purpose, non-infringement,
-absence of latent or other defects, accuracy, or the presence or absence of
-errors, whether or not known or discoverable. Where disclaimers of warranties
-are not allowed in full or in part, this disclaimer may not apply to You.
-
-b. To the extent possible, in no event will the Licensor be liable to You
-on any legal theory (including, without limitation, negligence) or otherwise
-for any direct, special, indirect, incidental, consequential, punitive, exemplary,
-or other losses, costs, expenses, or damages arising out of this Public License
-or use of the Licensed Material, even if the Licensor has been advised of
-the possibility of such losses, costs, expenses, or damages. Where a limitation
-of liability is not allowed in full or in part, this limitation may not apply
-to You.
-
-c. The disclaimer of warranties and limitation of liability provided above
-shall be interpreted in a manner that, to the extent possible, most closely
-approximates an absolute disclaimer and waiver of all liability.
-
-Section 6 – Term and Termination.
-
-a. This Public License applies for the term of the Copyright and Similar Rights
-licensed here. However, if You fail to comply with this Public License, then
-Your rights under this Public License terminate automatically.
-
-b. Where Your right to use the Licensed Material has terminated under Section
-6(a), it reinstates:
-
-1. automatically as of the date the violation is cured, provided it is cured
-within 30 days of Your discovery of the violation; or
-
-      2. upon express reinstatement by the Licensor.
-
-c. For the avoidance of doubt, this Section 6(b) does not affect any right
-the Licensor may have to seek remedies for Your violations of this Public
-License.
-
-d. For the avoidance of doubt, the Licensor may also offer the Licensed Material
-under separate terms or conditions or stop distributing the Licensed Material
-at any time; however, doing so will not terminate this Public License.
-
-   e. Sections 1, 5, 6, 7, and 8 survive termination of this Public License.
-
-Section 7 – Other Terms and Conditions.
-
-a. The Licensor shall not be bound by any additional or different terms or
-conditions communicated by You unless expressly agreed.
-
-b. Any arrangements, understandings, or agreements regarding the Licensed
-Material not stated herein are separate from and independent of the terms
-and conditions of this Public License.
-
-Section 8 – Interpretation.
-
-a. For the avoidance of doubt, this Public License does not, and shall not
-be interpreted to, reduce, limit, restrict, or impose conditions on any use
-of the Licensed Material that could lawfully be made without permission under
-this Public License.
-
-b. To the extent possible, if any provision of this Public License is deemed
-unenforceable, it shall be automatically reformed to the minimum extent necessary
-to make it enforceable. If the provision cannot be reformed, it shall be severed
-from this Public License without affecting the enforceability of the remaining
-terms and conditions.
-
-c. No term or condition of this Public License will be waived and no failure
-to comply consented to unless expressly agreed to by the Licensor.
-
-d. Nothing in this Public License constitutes or may be interpreted as a limitation
-upon, or waiver of, any privileges and immunities that apply to the Licensor
-or You, including from the legal processes of any jurisdiction or authority.

-# WebUSB Serial Support
-
-To date, this has only been tested on one port (espressif), on one board (espressif_kaluga_1).
-
-## What it does
-
-If you have ever used CircuitPython on a platform with a graphical LCD display, you have probably
-already seen multiple "consoles" in use (although the LCD console is "output only").
-
-New compile-time option CIRCUITPY_USB_VENDOR enables an additional "console" that can be used in
-parallel with the original (CDC) serial console.
-
-Web pages that support the WebUSB standard can connect to the "vendor" interface and activate
-this WebUSB serial console at any time.
-
-You can type into either console, and CircuitPython output is sent to all active consoles.
-
-One example of a web page you can use to test drive this feature can be found at:
-
-https://adafruit.github.io/Adafruit_TinyUSB_Arduino/examples/webusb-serial/index.html
-
-## How to enable
-
-Update your platform's mpconfigboard.mk file to enable and disable specific types of USB interfaces.
-
-CIRCUITPY_USB_HID = xxx
-CIRCUITPY_USB_MIDI = xxx
-CIRCUITPY_USB_VENDOR = xxx
-
-On at least some of the hardware platforms, the maximum number of USB endpoints is fixed.
-For example, on the ESP32S2, you must pick only one of the above 3 interfaces to be enabled.
-
-Original espressif_kaluga_1 mpconfigboard.mk settings:
-
-CIRCUITPY_USB_HID = 1
-CIRCUITPY_USB_MIDI = 0
-CIRCUITPY_USB_VENDOR = 0
-
-Settings to enable WebUSB instead:
-
-CIRCUITPY_USB_HID = 0
-CIRCUITPY_USB_MIDI = 0
-CIRCUITPY_USB_VENDOR = 1
-
-Notice that to enable VENDOR on ESP32-S2, we had to give up HID. There may be platforms that can have both, or even all three.
-
-## Implementation Notes
-
-CircuitPython uses the tinyusb library.
-
-The tinyusb library already has support for WebUSB serial.
-The tinyusb examples already include a "WebUSB serial" example.
-
-    Sidenote - The use of the term "vendor" instead of "WebUSB" was done to match tinyusb.
-
-Basically, this feature was ported into CircuitPython by pulling code snippets out of the

-Terminology
------------
-
-As our Code of Conduct states, we strive to use "welcoming and inclusive
-language." Whether it is in documentation or in code, the words we use matter.
-This means we disfavor language that due to historical and social context can
-make community members and potential community members feel unwelcome.
-
-There are specific terms to avoid except where technical limitations require it.
-While specific cases may call for other terms, consider using these suggested
-terms first:

-Note that "technical limitations" refers e.g., to the situation where an
-upstream library or URL has to contain those substrings in order to work.
-However, when it comes to documentation and the names of parameters and
-properties in CircuitPython, we will use alternate terms even if this breaks

-
-
-param_type
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-The type of the parameter. This could be, among others, ``int``, ``float``, ``str``, ``bool``, etc.

-.. code-block:: sh
-
-    :param ~busio.I2C i2c_bus: The I2C bus the DS3231 is connected to.
-
-
-To include references to CircuitPython modules, cookiecutter creates an entry in the
-intersphinx_mapping section in the ``conf.py`` file located within the ``docs`` directory.
-To add different types outside CircuitPython you need to include them in the intersphinx_mapping::

-for SPI devices. When possible, use one of these libraries for unpacking and
-packing registers. This ensures the packing code is shared amongst all
-registers (even across drivers). Furthermore, it simplifies device definitions
-by making them declarative (only data.)
-
-Values with non-consecutive bits in a register or that represent FIFO endpoints
-may not map well to existing register classes. In unique cases like these, it is

-Driver constant naming
---------------------------------------------------------------------------------
-
-When adding variables for constant values for a driver. Do not include the
-device's name in the variable name. For example, in ``adafruit_fancy123.py``,
-variables should not start with ``FANCY123_``. Adding this prefix increases RAM
-usage and .mpy file size because variable names are preserved. User code should
-refer to these constants as ``adafruit_fancy123.HELLO_WORLD`` for clarity.
-``adafruit_fancy123.FANCY123_HELLO_WORLD`` would be overly verbose.

+These are libraries and drivers available in separate GitHub repos. They are
+designed for use with CircuitPython and may or may not work with
+`MicroPython <https://micropython.org>`_.
+
+
+Adafruit CircuitPython Library Bundle
+--------------------------------------
+
+We provide a bundle of all our libraries to ease installation of drivers and
+their dependencies. The bundle is primarily geared to the Adafruit Express line
+of boards which feature a relatively large external flash. With Express boards,
+its easy to copy them all onto the filesystem. However, if you don't have
+enough space simply copy things over as they are needed.

-Environment Variables
-=====================
-
-CircuitPython 8.0.0 introduces support for environment variables. Environment
-variables are commonly used to store "secrets" such as Wi-Fi passwords and API
-keys. This method *does not* make them secure. It only separates them from the
-code.
-
-CircuitPython uses a file called ``settings.toml`` at the drive root (no
-folder) as the environment.  User code can access the values from the file
-using `os.getenv()`. It is recommended to save any values used repeatedly in a
-variable because `os.getenv()` will parse the ``settings.toml`` file contents
-on every access.
-
-CircuitPython only supports a subset of the full toml specification, see below
-for more details. The subset is very "Python-like", which is a key reason we
-selected the format.
-
-Due to technical limitations it probably also accepts some files that are
-not valid TOML files; bugs of this nature are subject to change (i.e., be
-fixed) without the usual deprecation period for incompatible changes.
-
-File format example:
-
-.. code-block::
-
-   str_key="Hello world" # with trailing comment
-   int_key = 7
-   unicode_key="œuvre"
-   unicode_key2="\\u0153uvre" # same as above
-   unicode_key3="\\U00000153uvre" # same as above
-   escape_codes="supported, including \\r\\n\\"\\\\"
-   # comment
-   [subtable]
-   subvalue="cannot retrieve this using getenv"
-
-
-Details of the toml language subset
------------------------------------
-
-* The content is required to be in UTF-8 encoding
-* The supported data types are string and integer
-* Only basic strings are supported, not triple-quoted strings
-* Only integers supported by strtol. (no 0o, no 0b, no underscores 1_000, 011
-  is 9, not 11)
-* Only bare keys are supported
-* Duplicate keys are not diagnosed.
-* Comments are supported
-* Only values from the "root table" can be retrieved
-* due to technical limitations, the content of multi-line
-  strings can erroneously be parsed as a value.

-CircuitPython behavior
-----------------------
-
-CircuitPython will also read the environment to configure its behavior. Other
-keys are ignored by CircuitPython. Here are the keys it uses:
-
-CIRCUITPY_BLE_NAME
-~~~~~~~~~~~~~~~~~~
-Default BLE name the board advertises as, including for the BLE workflow.
-
-CIRCUITPY_HEAP_START_SIZE
-~~~~~~~~~~~~~~~~~~~~~~~~~
-Sets the initial size of the python heap, allocated from the outer heap. Must be a multiple of 4.
-The default is currently 8192.
-The python heap will grow by doubling and redoubling this initial size until it cannot fit in the outer heap.
-Larger values will reserve more RAM for python use and prevent the supervisor and SDK
-from large allocations of their own.
-Smaller values will likely grow sooner than large start sizes.
-
-CIRCUITPY_PYSTACK_SIZE
-~~~~~~~~~~~~~~~~~~~~~~
-Sets the size of the python stack. Must be a multiple of 4. The default value is currently 1536.
-Increasing the stack reduces the size of the heap available to python code.
-Used to avoid "Pystack exhausted" errors when the code can't be reworked to avoid it.
-
-CIRCUITPY_WEB_API_PASSWORD
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-Password required to make modifications to the board from the Web Workflow.
-
-CIRCUITPY_WEB_API_PORT
-~~~~~~~~~~~~~~~~~~~~~~
-TCP port number used for the web HTTP API. Defaults to 80 when omitted.
-
-CIRCUITPY_WEB_INSTANCE_NAME
-~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Name the board advertises as for the WEB workflow. Defaults to human readable board name if omitted.
-
-CIRCUITPY_WIFI_PASSWORD
-~~~~~~~~~~~~~~~~~~~~~~~
-Wi-Fi password used to auto connect to CIRCUITPY_WIFI_SSID.
-
-CIRCUITPY_WIFI_SSID
-~~~~~~~~~~~~~~~~~~~
-Wi-Fi SSID to auto-connect to even if user code is not running.
