# Adafruit Community 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
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.
## 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
* 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
The goal of the standards and moderation guidelines outlined here is to build
and maintain a respectful community. We ask that you dont 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.
## Our Responsibilities
Project leaders 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
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 Helpers by tagging @community helpers. You may also send an
open message from any channel, or a direct message to @kattni#1507,
@tannewt#4653, @Dan Halbert#1614, @cater#2442, @sommersoft#0222, 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 communitys 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.
## 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.
## Attribution
This Code of Conduct is adapted from the [Contributor Covenant][homepage],
version 1.4, available at
<https://www.contributor-covenant.org/version/1/4/code-of-conduct.html>,
and the [Rust Code of Conduct](https://www.rust-lang.org/en-US/conduct.html).
For other projects adopting the Adafruit Community Code of
Conduct, please contact the maintainers of those projects for enforcement.
If you wish to use this code of conduct for your own project, consider
explicitly mentioning your moderation policy or making a copy with your
own moderation policy so as to avoid confusion.

Introduction
============

:target: https://circuitpython.readthedocs.io/projects/pn532/en/latest/

.. image:: https://travis-ci.org/adafruit/adafruit_CircuitPython_PN532.svg?branch=master
:target: https://travis-ci.org/adafruit/adafruit_CircuitPython_PN532
:alt: Build Status
.. todo:: Describe what the library does.
Dependencies
=============
This driver depends on:
* `Adafruit CircuitPython <https://github.com/adafruit/circuitpython>`_
* `Bus Device <https://github.com/adafruit/Adafruit_CircuitPython_BusDevice>`_
Please ensure all dependencies are available on the CircuitPython filesystem.
This is easily achieved by downloading
`the Adafruit library and driver bundle <https://github.com/adafruit/Adafruit_CircuitPython_Bundle>`_.
Usage Example
=============
.. todo:: Add a quick, simple example. It and other examples should live in the examples folder and be included in docs/examples.rst.
Contributing
============
Contributions are welcome! Please read our `Code of Conduct
<https://github.com/adafruit/adafruit_CircuitPython_PN532/blob/master/CODE_OF_CONDUCT.md>`_
before contributing to help this project stay welcoming.
Building locally
================
Zip release files
-----------------
To build this library locally you'll need to install the
`circuitpython-build-tools <https://github.com/adafruit/circuitpython-build-tools>`_ package.
.. code-block:: shell
python3 -m venv .env
source .env/bin/activate
pip install circuitpython-build-tools
Once installed, make sure you are in the virtual environment:
.. code-block:: shell
source .env/bin/activate
Then run the build:
.. code-block:: shell
circuitpython-build-bundles --filename_prefix adafruit-circuitpython-pn532 --library_location .
Sphinx documentation
-----------------------
Sphinx is used to build the documentation based on rST files and comments in the code. First,
install dependencies (feel free to reuse the virtual environment from above):
.. code-block:: shell
python3 -m venv .env
source .env/bin/activate
pip install Sphinx sphinx-rtd-theme
Now, once you have the virtual environment activated:
.. code-block:: shell
cd docs
sphinx-build -E -W -b html . _build/html
This will output the documentation to ``docs/_build/html``. Open the index.html in your browser to
view them. It will also (due to -W) error out on any warning like Travis will. This is a good way to
locally verify it will pass.
