摘要
给出了基于ARM7(44B0)的LED显示屏控制系统的设计解决方案,并通过CPLD对44B0的LCD接口进行变换,实现44B0与LED显示屏的无缝连接.利用嵌入式系统强大的数据处理能力和丰富的图形图像处理函数,使LED显示屏实现了灵活多样的图形图像显示功能.最后,给出了系统的硬件、软件设计方案以及CPLD的逻辑设计时序,对于实际应用具有参考价值.
This paper provides a solution for the design of LED display screen controlling system based on ARM7（44B0） and the realization of the connection between 44B0 and LED display screen through the change of LCD port of 44B0 by utilizing CPLD. With the powerful data processing ability and copious image and graphic functions of the imbedded system, the LED display screen is able to display images and graphics in numerous forms. This paper provides a blue print for the design of the hardware and software for the system and the logic design for the scheduling of CPLD which is a valuable reference for practical applications.
