CircuitPython module for the MCP23017/08 I2C and MCP23S17/08 SPI I/O extenders.

This driver depends on:

• Adafruit CircuitPython
• Bus Device

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

pip3 install adafruit-circuitpython-mcp230xx

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

sudo pip3 install adafruit-circuitpython-mcp230xx

To install in a virtual environment in your current project:

mkdir project-name && cd project-name python3 -m venv .env source .env/bin/activate pip3 install adafruit-circuitpython-mcp230xx

See examples/mcp230xx_simpletest.py for a demo of the usage.
