Has anyone used MCP23S17 with BS2?·
Does anyone know if SHIFTIN and SHIFTOUT is sufficient for this I/O expander?
Or does this chip simultaneously send out and receive data (real SPI) and thus require bit-bang method?
If anyone has some code on how to read, write to this chip, it would be appreciated.
