摘要
基于FPGA芯片设计了一种RGB数字接口的大尺寸彩色LED显示屏完整方案,提出了一种子块图像扫描寻址方法,使用同步串行接口技术,在扫描控制器与LED子模块间实现了高速图像数据传输,并分析了核心代码设计.实验证明设计可靠、结构灵活、性能优越、成本可控.
A design of lager-scalar color-LED-screen,for digital RGB interface is propdsed on the basis of FPGA chip.A method of sub-block image scanning and addressing is stated.The technology of synchronized serial interface is adapted to implement high speed image data transportation between LED sub-block and scanning controller,and analysze the VHDL code of kernel design.The experiment results show that the design is very stable,its constuction is flexible,its performance is excellent,and its cost is controllable.
