MCP23S17 object & demo

I am uploading a pasm driver that supports up to 8 MCP23S17's on four pins, and a demo program for it.

I remember seeing requests for such an object, so I decided to clean up and post my internal test code.

Enjoy!

(MIT License... so I will also submit it to Obex, once I can manage to log in there again...)

    Fantastic! I just searched the OBEX for any MCP23S17 or MCP23017 objects.

    :-)

    Glad it helps!

    FYI, it should also work with the older MCP23S16 and the MCP23S08 and MCP23S09

    Note, I leave IOCON=0, so register numbers will be different on the '08 and '09
