Abstract
A method and an apparatus are provided for operating an interface with an external device in an electronic device. A connection of the external device to the electronic device is recognized. It is determined whether the external device is a SAW device. A request signal is transmitted to the SAW device when the external device is the SAW device. A response signal corresponding to the request signal is received from the SAW device. The response signal is processed. Data is output according to the processed response signal.
Claims17
An electronic device comprising:
- a connector configured to connect to an external device;
- a controller configured to determine whether the external device is a Surface Acoustic Wave (SAW) device based on an identification (ID) value of the external device, to output a request signal to the SAW device through the connector when the external device is the SAW device, to receive a response signal corresponding to the request signal from the SAW device through the connector, to recognize, from among a plurality of types of sensors, a type of a sensor of the SAW device based on an ID code included in the response signal, and to process the response signal by executing an application corresponding to the recognized type of the sensor based on the ID code, wherein each of the plurality of types of sensors corresponds to a respective one of a plurality of applications;
- and
- an output interface unit configured to output data according to a result of processing the response signal,
- wherein the response signal further includes detection information on either a physical change or a chemical change according to the type of the sensor of the SAW device, each of the physical change and the chemical change corresponding to a respective one of the plurality of types of sensors.
