Hello,
Could you please tell me if MCP23017 is working on ESP32 ?
I have tried to use it but nothing is sent on the I2C port
Do you have an example ?
thx for your prompt reply, we need to go forward for this project.

Re: ESP32 + MCP23017 component is not working
Hi Seb.
I have 2 different test files.
If not working with the I2C set to channel1, try changing to software mode.
