最后连接成一个整体的系统模块

进行仿真和调试

完成FPGA控制系统的设计。通过SPI通信协议发送数据

完成了6464的LED屏的图形显示

从而验证了LED大屏幕的设计方法。本方案实现的显示控制系统方法

满足目前LED大屏幕区域显示和高速处理图像数据的要求

具有稳定性高、设计灵活等特点。

Abstract

Through the study of the large outdoor full color LED display screen

a control system of LED display screen was designed based on FPGA. The system was designed on the platform of the Altera DE1 development board. In the software development environment of QuartusⅡ

a hierarchical design was applied. A complete system module consists of a frequency divided clock module

a module for data acquisition and reorganization

and a scan driver module with the use of the Verilog HDL language. Simulation and test were also conducted for the final FPGA control system. Moreover

the design of a LED large screen was also verified by using the SPI communication protocol to send data to realize the graphic display of a 6464 LED screen. The display control system method of this scheme met the demand of current LED area of the large screen display and image data high-speed processing

having the characteristics of high stability

flexible design etc.
