The LED display screen system consists of software control system, wireless transmission system, device main controller, LED display dot matrix, power supply, and other components
System working process: The software control system mainly completes tasks such as image and text editing, font extraction and saving, image preview and file transmission; The wireless transmission system mainly completes the transmission of file information from a PC to an LED display. In the hardware control system, the main task of the LED dot matrix is to display information through current control. The control of the scanning drive method of the microcontroller drives the row and column of the LED dot matrix, achieving device drive and ultimately achieving the received image and text display function.
2. Analysis and Design of Computer Software Modules
The software module is divided into an editing section and a control communication section. The editing section implements the editing function of graphic and text files, and the communication section completes the transmission of files to the microcontroller storage module through RS-232C serial communication. The communication section will be introduced in detail in Chapter 3. The system is designed using the Windows operating system to open a text editing window. The pixels in the customer area are the same as the actual LED dot matrix display screen pixels, with functions similar to Word document editing tools, including editing module, drawing module, text editing module, color control module, display effect loading module, preview module, and information download module.
