A CircuitPython driver class for the NAU7802 24-bit ADC.

Dependencies

=============

This driver depends on:

* `Adafruit CircuitPython `_

* `Bus Device `_

* `Register `_

Please ensure all dependencies are available on the CircuitPython filesystem.

This is easily achieved by downloading

`the Adafruit library and driver bundle `_

or individual libraries can be installed using

`circup `_.

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 cedargrove_nau7802

Or the following command to update an existing version:

.. code-block:: shell

    circup update

Installing for Blinka with Pip

==============================

.. code-block:: shell

    pip3 install cedargrove-nau7802

Usage Example

=============

.. code-block:: py

    import board

    from cedargrove_nau7802 import NAU7802

    # Instantiate NAU7802 ADC

    nau7802 = NAU7802(board.I2C(), address=0x2A, active_channels=2)

``nau7802_simpletest.py`` and other examples can be found in the ``examples`` folder.
