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

Hi Fernando,
you must reduce the DigitalInput object to a byte like so:byte byteValReadAll = 0; void setVal(uint8_t pin, uint8_t value){ if (value==HIGH){ byteValReadAll = byteValReadAll | bit(pin); }else{ byteValReadAll = byteValReadAll & ~bit(pin); } } [...] setVal(P0, digitalInput.p0); setVal(P1, digitalInput.p1); setVal(P2, digitalInput.p2); setVal(P3, digitalInput.p3); setVal(P4, digitalInput.p4); setVal(P5, digitalInput.p5); setVal(P6, digitalInput.p6); setVal(P7, digitalInput.p7); Serial.println(byteValReadAll, BIN); [...]Bye Renzo
