# ESP32 MCP230XX expander driver/library

This is a single-file header-only C++ style library (see files in `main/include/`) for driving the **MCP230XX** MicroChip's GPIO expander from an **ESP32** microcontroller.

Currently supported are:

- MCP23008

- MCP23009

- MCP23016

- MCP23017

- MCP23018

It is based on another library:
