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.

Hi Seb.
I have 2 different test files.
If not working with the I2C set to channel1, try changing to software mode.

thx , I will try
