According to the issue SoftwareSerial: Make the bus more general => SPI / I2C (HW and SW)

There is also a SPI version of that chip. Why not implementing that chip also?

Hi,

Sorry for the delay. While I'd like to see an SPI version of this library, I've never played with SPI myself and I don't have an MCP23S17 at hand to develop those modifications.

If you do, I strongly encourage you to give it a try by modifying the library code. On the top of my head, a base class with high level implementation and two classes for MCP2017 and MCP23S17 communication protocol with both signatures of writeRegister and readRegister might do the trick :)
