Embodiment Construction

[0036] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with this disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as recited in the appended claims.

[0037] According to the standard specification of the USB Association, the USB Type-C interface has two opposite pin faces, each with 12 pins. The Type-C interface includes a configuration channel CCl pin and a CC2 pin (Configuration Channel, configuration channel) located on two opposite pin faces. The functions of the CCl pin and the CC2 pin are to detect the positive and negative insertion, to ...

Abstract

The invention relates to an interface control method, an interface control device and a storage medium. The interface control method comprises the following steps: monitoring an interrupt signal received by an application processor, wherein the interrupt signal is sent when an interface chip responds to a double-role port switching edge of a configuration channel pin and exceeds a protocol threshold; obtaining the receiving times of the interrupt signal; and when the receiving frequency reaches a set threshold value, stopping supplying power to the interface chip. Through the embodiment of theinvention, the terminal power consumption caused by liquid feeding of the C-type interface of the universal serial bus can be reduced, the interface corrosion is prevented, and the use safety of a user is ensured.

Description

technical field [0001] The present disclosure relates to the technical field of Universal Serial Bus (Universal Serial Bus, USB) interfaces, and in particular, to an interface control method, an interface control device and a storage medium. Background technique [0002] With the development of technology, the Universal Serial Bus Type-C (USB Type-C) interface is widely used in electronic devices such as smart phones and tablet computers. Electronic devices can be connected to external Type-C devices through the Type-C interface to realize interaction between devices. [0003] For the convenience of users, the setting of the Type-C interface of electronic devices is usually exposed, so that the Type-C interface is easily exposed to conductive liquids such as sweat and oil. The configuration channel pins of the Type-C interface are continuously charged. When there is a conductive liquid, it is easy to form an electrochemical reaction loop inside the interface. It increases ...
