Data transmission methods, electronic devices, and computer-readable storage media

Abstract

The invention proposes a method for transmitting data, an electronic device, and a storage medium readable by a computer. An uplink interface and a downlink interface are implemented on each input device of the electronic device. The uplink interface is connected to a processor or upper-level input device, and the downlink interface is connected to a lower-level input device. The page processing module for each input device can process image data collected by the current-level device and data sent by the lower-level input device connected via the downlink interface, and then transmit the processed data to the processor or upper-level input device via the uplink interface. In this way, the input devices are cascading, and only one of the input devices needs to be connected to the processor. Therefore, the number of interfaces and signal pins between the processor and input devices is reduced.
