create array of PCF8575 #8

Closed ear9mrn closed 2 years ago

ear9mrn commented 2 years ago

I would to declare an array of multiple PCF8575 devices within a struct, something like:

PCF8575 PCF[DEVICES];

Then, in another part of my code do something like:

PCF[0].digitalRead(PINNUM);

I cannot figure out how to do this with this library as it appears at minimum I need to assign an address with the constructor.

Any suggestions would be greatly appreciated.

Thanks.
