A CircuitPython driver class for the NAU7802 24-bit ADC

Introduction

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:

pip3 install circup

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

circup install cedargrove_nau7802

Or the following command to update an existing version:

circup update

Installing for Blinka with Pip

pip3 install cedargrove-nau7802

Usage Example

import board
from cedargrove_nau7802 import NAU7802

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