.. A driver for Pixie - 3W Chainable Smart LED Pixel

Dependencies
=============
This driver depends on:

* `Adafruit CircuitPython <https://github.com/adafruit/circuitpython>`_

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>`_.

Installing from PyPI
====================
On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally `from
PyPI <https://pypi.org/project/adafruit-circuitpython-pixie/>`_. To install for current user:

.. code-block:: shell

    pip3 install adafruit-circuitpython-pixie

To install system-wide (this may be required in some cases):

.. code-block:: shell

    sudo pip3 install adafruit-circuitpython-pixie

To install in a virtual environment in your current project:

.. code-block:: shell

    mkdir project-name && cd project-name
    python3 -m venv .venv
    source .venv/bin/activate
    pip3 install adafruit-circuitpython-pixie

Usage Example
=============

.. code-block:: python

    import time
    import board
    from rainbowio import colorwheel
    import adafruit_pixie
    import busio

    uart = busio.UART(board.TX, rx=None, baudrate=115200)

    num_pixies = 2  # Change this to the number of Pixies LEDs you have.
    pixies = adafruit_pixie.Pixie(uart, num_pixies, brightness=0.2, auto_write=False)


    while True:
    for i in range(255):
        for pixie in range(num_pixies):
            pixies[pixie] = colorwheel(i)
        pixies.show()
