I am doing program compilations and I have such errors. I thought something was wrong with my version of the program and tried on a different computer, but the effect is the same.
What is wrong ?

Can soft be used to control roller shutters ? If so, I still have a question, how long can the wires be from mcp23017 to physical buttons ?

Hello Elmaya. I have a problem and a question at the same time. You created a sketch to support 16 relays via the mcp23017 expander. Would it be possible for you to adapt the sketch to support the AnalogTek AT8574D expander. I raised the problem here viewtopic.php?p=194786#p194786 but it has not been solved. Best regards
