Thanks for your work in this, would love if the Arduino examples included support for reading an entire bank of inputs all at once and gave back the binary result

Thanks

I believe you can, using the .readGPIOA() or .readGPIOB() methods.

Yep. For the MCP23x17, use readGPIOA(), readGPIOB() or readGPIOAB(). For the MCP23x08, use readGPIO()
