Abstract
Provided is a method and apparatus for identifying a type of an external device connected to an interface connector in an electronic device. The electronic device may measure a voltage of power that is input to a power supply terminal of the interface connector that includes the power supply terminal and is configured to connect with an external device. The electronic device may identify a type of the external device connected to the interface connector based on the voltage of the input power. In addition, other embodiments are also possible.
Claims14
A method for identifying an external device in an electronic device, the method comprising:
- measuring a voltage of power that is input to a power supply terminal of an interface connector that includes the power supply terminal and is configured to connect with an external device;
- and
- identifying a type of the external device connected to the interface connector based on the voltage of the input power,
- wherein identifying the type of the external device includes:
- identifying the external device as a process test tool, if the voltage of the input power is less than a threshold;
- identifying the external device as a device other than the process test tool, if the voltage of the input power is greater than or equal to the threshold;
- determining whether communication terminals of the interface connector are short-circuited with each other, if the external device is the device other than the process test tool;
- and
- identifying the external device as a device capable of communication through the interface connector, if the communication terminals are not short-circuited with each other.
An electronic device comprising:
- an interface connector that includes a power supply terminal and is configured to connect with an external device;
- and
- a controller configured to:
- measure a voltage of power that is input to the power supply terminal;
- identifying the external device as a process test tool if the voltage of the input power is less than a threshold;
- identifying the external device as a device other than the process test tool if the voltage of the input power is greater than or equal to the threshold;
- determining whether communication terminals of the interface connector are short-circuited with each other if the external device is the device other than the process test tool;
- and
- identifying the external device as a device capable of communication through the interface connector if the communication terminals are not short-circuited with each other.
A non-transitory computer-readable recording medium storing a program to be performed in a computer, wherein the program includes an executable instruction that, when is executed by a processor, cause the processor to perform operations comprising:
- measuring a voltage of power that is input to a power supply terminal of an interface connector that includes the power supply terminal and is configured to connect with an external device;
- and
- identifying a type of the external device connected to the interface connector based on the voltage of the input power,
- wherein identifying the type of the external device includes:
- identifying the external device as a process test tool, if the voltage of the input power is less than a threshold;
- identifying the external device as a device other than the process test tool, if the voltage of the input power is greater than or equal to the threshold;
- determining whether communication terminals of the interface connector are short-circuited with each other, if the external device is the device other than the process test tool;
- and
- identifying the external device as a device capable of communication through the interface connector, if the communication terminals are not short-circuited with each other.
