Hello All-
This is a bit off topic as I am now asking for a chip recomendation. I am using multiple MCP23016s in a design and now I need more than the 8 which is addressable.

I looked into a PIC as a I2C slave (great examples) but I was wondering if anyone has used a chip like the 23016 but that has 4 address lines for a total of 16 I2C port expanders.
Otherwise I will start breadboarding the PIC I2C slave idea.

If this is not appropriate for this forum (as it is PICBasic/Pro), my apologies.

-Regards
