Abstract
A peripheral interface multiplexing method. The method includes receiving, by using a first pin in a peripheral interface of user equipment, a coded signal sent by an external device, where the coded signal includes a first electrical characteristic value of the first pin; decoding the coded signal to obtain a decoded signal, where the decoded signal includes a control signal that corresponds to the first electrical characteristic value of the first pin, and the control signal is used to control the peripheral interface to transmit a target signal that a user requests to transmit; and controlling, according to the control signal, a pin that is in the peripheral interface and used for signal transmission to transmit the target signal. Therefore, communications interfaces of user equipment can be extended without increasing a quantity of peripheral interfaces, so that the user equipment provides more communications manners, and user experience is improved.
