摘要
目前,LED点阵显示文字图形的控制系统,价格昂贵,功能难以扩展,使用不便。文中对LED电子屏幕的主要控制技术及其应用领域作了简要介绍,针对实际应用需要设计出一种基于Labview与单片机控制的LED电子屏幕。在提出系统整体设计方案基础上详细阐述了由Labview实现UCDOS下字库点阵数据提取方法,并设计出信息编辑与管理系统,论述了LED点阵显示原理及单片机控制系统硬件与软件设计思想。
Present LED lattice demonstration writing graph control systems are expensive, inconvenient and barely extensible. This article briefly introduces the key technology and application of LED electron screen control, and presents a LED electron screen design based on Labview and MCU in view of practical application. The realization of lattice data extraction by Labview is elaborated in detail, and information edition and management system is designed. The control system hardware design and the software design concept are also discussed.
