Mux over i2c #10

Hello, first of all thanks for the work, I am trying to add an mcp23017 mutiplexer via i2c but I cannot get the communication between it and esp32s3. The information I have found does not take me anywhere. Would you know how to configure the gpio's for this purpose, thank you

Hi, first sorry for the very late reply. Somehow missed the Github mail about it. I'm using MCP23017 in conjunction with the library and an ESP32-S3 without problems.

However, I also struggled with some I2C devices at the beginning. I tried several pin combinations until it worked with the board default I2C pin settings.
