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.
