Daisy Seed and PCF8575 Port Extender

Hi, I’m struggling to get the PCF8575 IO port extender working - its a 16 port board.
Does any one have code to set up the I2C and then read the 16 ports?


libDaisy does not support these yet. Recently I requested support for the PCF8574 here: Support PCF8574 I2C port expanders · Issue #600 · electro-smith/libDaisy · GitHub
I assume that the 8575 would work very similarly.
