PORTABLE DEVICE AND PERIPHERAL EXTENSION DOCK

摘要

An electronic device includes a housing, a connector port embedded in the housing for a peripheral device inserted therein and a switching device. The processor is electrically connected to the connector port and includes a detection pin and a 1-wire pin. The switching device is coupled between the connector port and the processor to selectively connect the connector port to one of the detection pin or the 1-wire pin. When the peripheral device is inserted into the connector port, the processor controls the switching device to connect the connector port to the detection pin to determine whether the connected peripheral device is a 1-wire device. When the processor determines that the connected peripheral device is a 1-wire device, the processor controls the switching device to connect the connector port to the 1-wire pin and the processor executes 1-wire communication with the peripheral device via the 1-wire pin.
