pcf8574 ReadAll in low memory compare to single value byte

4 years ago

Hello Everyone, I have a byte field that I need to compare with ReadAll without using low memory, After several attempts I couldn't, how to compare

PCF8574 :: DigitalInput di = pcf85741.digitalReadAll ();

with byte value? ex:


byte valor = 220;
if(valor == PCF8574 :: DigitalInput di = pcf85741.digitalReadAll ());

Thank you
