Hi Michiel

now It’s possible to check the status with

if (pcf8574.begin()){
Serial.println("pcf8574 started!");
}else{
Serial.println("pcf8574 not started!");
}

or

if (pcf8574.digitalWrite(P7, startVal)){
Serial.println("Write ok");
}else{
Serial.println("Write not ok");
}

It’s also possible to get last writeStatus with

uint8_t getTransmissionStatusCode() const {
return transmissionStatus;
}

bool isLastTransmissionSuccess(){
return transmissionStatus==0;
}

Bye Renzo
