摘要
LED产业是21世纪最具有发展前景的高新技术产业。根据LED显示模块结构特点,应用FPGA技术对LED显示屏的控制系统进行设计。显示控制系统由输入接口模块、信号写入控制模块、信号读取控制模块、读取控制模块、存储模块、动态控制模块等模块构成。程序采用Verilog-HDL语言编写,从而实现外部输入信号的地址生成、选择、存储、动态控制等处理。实验测试结果表明:系统可以实现字符或图案的动态显示,具有实际应用价值。
LED industry is the most promising high-tech industry in the 21st century,according to the structural characteristics of the LED display module,combining with FPGA technology.It designed a large-screen LED display control system.Display control system consists of input interface modules,signal write control module,the signal read control module,read control module,memory module and dynamic control modules,using Verilog-HDL language for programming,the design achieved a series of processing of the external input signal,including the address generation,selection,storage and dynamic control.The experimental results show that： the system can realize the dynamic display of character or pattern,has a practical application.
