Abstract
The invention discloses a multi-state identification method and system, and a terminal. The multi-state identification system comprises a GPIO interface, a charging and discharging device and a detection module; the detection module is used for: when the GPIO interface is electrically connected with a device to be detected, if the GPIO interface detects a high level, determining the device to be detected as a pull-up state; if the GPIO interface detects a low level, determining the device to be detected as a pull-down state; the detection module is further used for detecting a charging time ofthe device to be detected to charge the charging and discharging device, and obtaining the type of the device to be detected when the device to be detected is in the pull-up state; and the detectionmodule is further used for detecting a discharging time of the charging and discharging device to discharge the device to be detected, and obtaining the type of the device to be detected when the device to be detected is in the pull-down state. The multi-state identification system disclosed by the invention can identify different types of devices to be detected according to different resistancevalues, thereby realizing that one GPIO interface can identify different types of components of different suppliers, so that the utilization rate of the GPIO interface is improved.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a polymorphism identification method, system and terminal. Background technique [0002] In the terminal development process, it is usually necessary to use various types of components (such as display modules, camera modules, etc.) provided by different suppliers, and the terminal needs to correctly identify each component to drive the corresponding component. [0003] Each component has its own component ID (identification number), and is expressed in binary form. In the prior art, it is connected to the component ID end of the component through a GPIO (general input / output) interface. However, each GPIO interface can only identify components from 2 suppliers (that is, distinguish them by 1 and 0). When it is necessary to identify components from 00 to distinguish); when it is necessary to identify components from 8 suppliers, three GPIO interfaces are required ...
