Portable device and peripheral extension dock

摘要

An electronic device including a housing, a connector port and a switching device is provided. The connector port is embedded in the housing for a peripheral device inserted therein to electrically connect thereto. The processor is electrically connected to the connector port and comprises 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.

主权项

1. An electronic device, electrically connected to an extension device to generate a 1-wire data path and an interrupt path, wherein the extension electrically connects to at least one peripheral device, the electronic device comprising:
a housing; a connector port embedded in the housing, electrically connecting to the extension device and to the peripheral device connected to the extension device, wherein when the peripheral device is connected to or removed from the extension device, an interrupt signal is transmitted to the connector port; a processor comprising a detection pin, a 1-wire pin and an interrupt pin, electrically connecting to the connector port, wherein the interrupt pin is connected to the interrupt path via the connector port to receive the interrupt signal; and a switching device coupled between the connector port and the processor, selectively connecting the 1-wire data path to one of the detection pin or the 1-wire pin, wherein when the processor receives the interrupt signal via the interrupt pin, the switching device connects the 1-wire pin to the 1-wire data path, and the processor scans the peripheral device via the 1-wire path to acquire a status of the peripheral device.
