Description

Data transmission method and electronic equipment Technical Field The embodiment of the application relates to the technical field of electronics, in particular to a data transmission method and electronic equipment. Background The mobile industry processor interface (mobile industry processor interface, MIPI interface), which is a standardized hardware interface, is widely used in electronic devices to achieve high-speed data transmission. The signal driving capability requirements of different electronic devices or different devices on the MIPI interface are different. The method is limited by factors such as board level design differences such as board level wiring length and the like, driving capability differences of modules, capability parameter differences of corresponding receiving ends of MIPI interfaces and the like, and signal driving capability differences of MIPI interfaces applied to different electronic equipment occur, so that the quality of data transmitted through the MIPI interfaces is affected. Disclosure of Invention The embodiment of the application provides a data transmission method and electronic equipment, which are used for adjusting configuration information of an MIPI interface and ensuring the quality of data transmitted through the MIPI interface. In order to achieve the above purpose, the embodiment of the present application adopts the following technical scheme: In a first aspect, a data transmission method is provided and applied to an electronic device, wherein the electronic device comprises a first module and a second module, and the first module transmits data to the second module through a mobile industry processor MIPI interface. The method comprises the following steps: And controlling the first module to adopt the first configuration information to transmit data to the second module through the MIPI interface. In the case of an abnormality in the transmission data, it means that the first module transmits the data to the second module through the MIPI interface, and it is inappropriate to adopt the first configuration information. In this case, the first module is controlled to transmit data to the second module through the MIPI interface using the second configuration information. Thus, the adjustment of the configuration information of the MIPI interface is realized. The first configuration information and the second configuration information are different configuration information of the MIPI interface, and transmission parameters are different when the different configuration information is adopted to transmit data through the MIPI interface. The transmission parameters include current and signal quality. The MIPI interface configuration information can characterize the signal driving capabilities of the MIPI interface. When different configuration information is adopted, the signal driving capability of the MIPI interface is different. When the signal driving capability of the MIPI interface is different, the current and the signal quality are different when data is transmitted through the MIPI interface. Therefore, through the scheme, the signal driving capability of the MIPI interface is matched with the current data transmission requirement of the electronic equipment, abnormal situations of data transmission are avoided, and therefore the quality of data transmitted through the MIPI interface is improved. In a possible implementation manner of the first aspect, after controlling the first module to use the second configuration information and transmitting data to the second module through the MIPI interface, the electronic device may further monitor whether there is an abnormality in transmitting data to the second module through the MIPI interface by the first module. If the first module adopts the second configuration information and there is still abnormal transmission data in the process of transmitting data to the second module through the MIPI interface, the electronic device can adjust the second configuration information into other configuration information, such as third configuration information. And so on until the configuration information adopted by the first module currently, transmitting data to the second module through the MIPI interface is no longer abnormal. In a possible implementation manner of the first aspect, the second current when the second configuration information is used to transmit data through the MIPI interface is higher than the first current when the first configuration information is used to transmit data through the MIPI interface. That is, the configuration information adopted by the first module is adjusted from the first configuration information to the second configuration information, so that the current when the first module transmits data to the second module is improved, that is, the signal driving capability of the MIPI interface is improved. In the scheme, the configuration information adopted by the electroni
