MCP23018 support

Open Donkie opened this issue 3 years ago • 3 comments

Hi, good job on the rewrite, looks very good. Is there any plans on supporting the MCP23018 variant? It's pretty much the same as the MCP23017, with minor differences. I could use this library almost out of the box, the only issue I found so far is that this library does not support enabling the internal pull-up resistor for the OUTPUT mode, it only enables when choosing INPUT_PULLUP (which makes sense since MCP23017 only supports input pull-up.

The OUTPUT_OPEN_DRAIN mode should probably be accounted for as well then.
