Hello, I have a problem with MCP23017 - I've kinda "copied" python example code into JS and it doesn't work. Does anybody have a working example?

@jas777 Did you ever get it to work?
@jperkin Does this lib support using a port expander (or, is there any reason it wouldn't)?

Not directly, it only knows about native pins, but there's no reason why you can't use it to drive one.
