CircuitPython driver for the Adafruit PCM51xx I2S DAC


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://circuitpython.org/libraries>`_
or individual libraries can be installed using
`circup <https://github.com/adafruit/circup>`_.

`Purchase one from the Adafruit shop <http://www.adafruit.com/products/6421>`_

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-pcm51xx/>`_.
To install for current user:

.. code-block:: shell

    pip3 install adafruit-circuitpython-pcm51xx

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

.. code-block:: shell

    sudo pip3 install adafruit-circuitpython-pcm51xx

To install in a virtual environment in your current project:

.. code-block:: shell

    mkdir project-name && cd project-name
    python3 -m venv .venv
    source .env/bin/activate
    pip3 install adafruit-circuitpython-pcm51xx

Installing to a Connected CircuitPython Device with Circup
==========================================================

Make sure that you have ``circup`` installed in your Python environment.
Install it with the following command if necessary:

.. code-block:: shell

    pip3 install circup

With ``circup`` installed and your CircuitPython device connected use the
following command to install:

.. code-block:: shell

    circup install adafruit_pcm51xx

Or the following command to update an existing version:

.. code-block:: shell

    circup update

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

.. code-block:: python

	import board
	import busio
	import adafruit_pcm51xx

	i2c = board.I2C()

	pcm = adafruit_pcm51xx.PCM51XX(i2c)

	pcm.volume_db = (0.0, 0.0)
	left_db, right_db = pcm.volume_db
	print(f"Volume set to: L={left_db}dB, R={right_db}dB")

	pcm.mute = False
	print(f"Muted: {pcm.mute}")
