    Serial.begin(9600);

        while (1) {
            delay(1000);
        }
    }
    // Gets the 64-bit unique address of CT1780,return: Address data (array)
	uint8_t *uniqueAddr = CT1780.getUniqueAddr();
    // Get the user-configured address of CT1780 (in ScratchPad)
	uint8_t configAddr = CT1780.getConfigAddr();
    Serial.print("unique addr is: ");
    for(uint8_t i=0;i<8;i++){
        Serial.print(uniqueAddr[i],HEX);
        Serial.print(" ");
    }
    Serial.println();
    Serial.print("config addr is: ");
    Serial.println(configAddr,HEX);
}

void loop() {
    // Read probe temperature data
    Serial.print("Temperature : ");
	Serial.print(CT1780.getCelsius());
    Serial.println(" C");
    delay(1000);
}

Result

• The Arduino prints the current temperature of a K-type thermocouple probe to the serial port every 1 second.
