Interfacing with MCP23017

Honored Contributor II

Has anyone successfully used the normal Wire and Adafruit mcp23017 ( drivers on the ESP8266? I've been doing some basic testing but haven't been able to blink an LED yet. 


I did see a different library at but it wasn't in the normal Arduino IDE library format and I didn't want to go to the work of reformatting the files if it wouldn't work.
