Basically I want to convert the Settimino (arduino Snap7 library) across to WiFi using the nodeMCU as an arduino. I have edited the Settimino library to #include ESP8266WiFi and changed the class from ethernet to WiFi, however I get compiler errors from Arduino IDE that I dont quite know how to fix.
Has anyone else had experience with porting an ethernet based library to wifi or how to fix these errors.
Thank you.
