Methods

  /**
   * @fn: DFRobot_CT1780
   * @brief: Constructor, passing in the data pin of the CT1780 connection
   * @param pin: The pin of the OneWire data cable connection
   */
  DFRobot_CT1780(uint8_t pin);
  /**
   * @fn: searchDevice
   * @brief: Search for CT1780 device connected to the bus
   * @param newAddr:If a new device is retrieved, the 64-bit unique ID of the device is stored at that address
   * @return: Returns 1 if a new address has been returned. A zero might mean that the bus is shorted, there are no devices, or you have already retrieved all of them.
   */
  int searchDevice(uint8_t *newAddr );
  /**
   * @fn: getCelsius
   * @brief: Read probe temperature data
   * @param newAddr:device address
   * @return: float Temperature value (in degrees Celsius),Return NAN on failure.
   */
  float getCelsius(uint8_t *newAddr);
