digitalReadAll

[Le-Ze]

Hi.
Why doesn't it work?
Am I making a mistake somewhere?

void loop()
{
pcf8575.digitalWrite(P10, HIGH);
int p10Digital = pcf8575.digitalRead(P10);
Serial.println(p10Digital);
PCF8575::DigitalInput di = pcf8575.digitalReadAll();
Serial.print(di.p10);
Serial.print(" - ");
Serial.print(di.p11);
Serial.print(" - ");
Serial.print(di.p12);
Serial.print(" - ");
Serial.println(di.p13);
delay(5000);
//---------------------------------------------------
pcf8575.digitalWrite(P10, LOW);
int p10Digital1 = pcf8575.digitalRead(P10);
Serial.println(p10Digital1);
PCF8575::DigitalInput di1 = pcf8575.digitalReadAll();
Serial.print(di1.p10);
Serial.print(" - ");
Serial.print(di1.p11);
Serial.print(" - ");
Serial.print(di1.p12);
Serial.print(" - ");
Serial.println(di1.p13);
delay(5000);
}

ser.monitor

They need to write the status P10 - P17 via the ser.monitor 00000000

Hi,
It seems ok, there is an internal buffer that is resetted when the value is read, and is set when the value change.
