Abstract
A portable electronic device and an accessory device thereof, and an operating method for a portable electronic device. According to the disclosure, an accessory device coupled at a universal serial bus connector of a portable electronic device is detected and identified via the identification pin of the universal serial bus connector. When it is identified that the accessory device supports 1-wire communication via the identification pin, the accessory device is accessed via the 1-wire communication via the identification pin.
Claims13
A portable electronic device, comprising:
- a device body;
- a universal serial bus connector, equipped on the device body for insertion of an accessory device to electronically connect the accessory device to the portable electronic device;
- and
- a processing unit and a switch, wherein the switch, controlled by the processing unit, selectively couples an identification pin of the universal serial bus connector to different receiving terminals of the processing unit for different functions, and thereby the processing unit detects and identifies the accessory device via the identification pin of the universal serial bus connector and, when the accessory device supports 1-wire communication via the identification pin, the processing unit communicates with the accessory device via the 1-wire communication.
An accessory device supporting 1-wire communication with a portable electronic device, comprising:
- a memory unit, stored with operation parameters for the portable electronic device;
- and
- a universal serial bus connector, connecting to the portable electronic device, wherein an identification pin of the universal serial bus connector is utilized by the portable electronic device to detect and identify the accessory device and to perform 1-wire communication with the accessory device after identifying the accessory device, and thereby the operation parameters stored in the memory unit are provided to the portable electronic device.
An operating method for a portable electronic device, comprising:
- using an identification pin of a universal serial bus connector of a portable electronic device to detect and identify an accessory device connected to the universal serial bus connector;
- and
- communicating with the accessory device by 1-wire communication via the identification pin when it is identified that the accessory device supports the 1-wire communication via the identification pin.
