Introduction

My own contribution for the CircuitPython module for the MCP23S17 SPI I/O extenders.

Dependencies

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.

Installing from PyPI

It is not available yet, since I just created this independently from the MCP230xx library from adafruit. I hope they can upload this to pypi.

Download to your project

Download the entire folder. It must be named as it is adafruit_mcp23sxx. Then copy and past this folder in your project.

Usage Example

See examples/mcp230xx_simpletest.py for a demo of the usage and the examples/mcp23s17_expandable_mcp23017_cs.py, to learn how to use a total of 6 MCP23S17 and use 1 MCP23017 as chip select controller.
