Portable device and peripheral extension dock

摘要

An electronic device includes a housing, a connector port and a switching device. The connector port receives a peripheral 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.

主权项

1. An extension device coupled to an electronic device and configured to establish an electrical connection between the electronic device and a peripheral device or a 1-wire peripheral device, the extension device comprising:
a first connector, electrically connecting to the 1-wire peripheral device, wherein the first connector comprises a first detection pin, a first connection pin and a first 1-wire pin, the first connection pin being releasably coupled to the electronic device; a second connector, electrically connecting to the peripheral device, wherein the second connector comprises a second detection pin, a second connection pin and a second 1-wire pin, the second connection pin being releasably coupled to the electronic device; and a controller comprising:
a first interrupt pin coupled to the first detection pin;a second interrupt pin coupled to the second detection pin; andan output pin releasably coupled to a processor of the electronic device, wherein when a logic state of the first interrupt pin or the second interrupt pin changes, an interrupt signal is output from the controller to the processor of the electronic device via the output pin, and in response to the interrupt signal, an electrical connection between the electronic device and the 1-wire peripheral device or the peripheral device is established through the first connection pin or the second connection pin, wherein the extension device, in its entirety, is releasably coupled to the electronic device.
