基于51单片机的数字LED显示 摘要： 基于89 C51单片机的数字显示标题硬件实现和软件设计,阐述了它的工作原理。介绍了研制过程中遇到的问题和解决办法。通过实验和运行,那头性能可靠,满足设计指标参数,具有广阔的市场前景,然后是成熟和普及。在显示领域,LED显示装置系列微电子技术、计算机技术和信息处理于一体,以其色彩鲜艳、动态范围、高亮度、清晰度高,低电压操作,能耗低、使用寿命长、耐冲击、色彩艳丽、工作可靠、稳定的优势,成为新一代的显示媒体,目前,LED显示屏已被广泛应用于大型广场,商业广告、信息传播、新闻发布、证券交易,能满足不同环境的需要。由单片机外围电路系统,显示电路、单片机、最小的系统构成。该系统的安装是容易的检测、软件功能完善、工作可靠、精度高的优点。论述了单片机控制的液晶数字显示系统,阐述了软件的基本原理,实现您的系统使用的设计及模拟和系统的应用领域。 关键词:单片机AT89C51、液晶数字显示, 凯尔软件bstract Based on the 89 C51 SCMs digital display header hardware realization and the software design, expounds its principle of work. Introduces the developing process of the multiplier encounter problems and solving methods. Through the test and operation, that the header reliable performance, to meet the design index parameters, and has a broad market prospect, and then the mature and popularity. As in the display field, LED display set series microelectronics technology, computer technology and information processing in the integral whole, with its colourful, dynamic range, high brightness, high-definition, low voltage operation, low consumption, long service life, impact resistance, gorgeous colour and stable and reliable work, become the advantage of a new generation of show media, at present, the LED display has been widely used in large square, commercial advertising, information dissemination, press conference, securities trading, can satisfy the need of different environment. By single-chip microcomputer system, peripheral circuit and single-chip microcomputer and show circuit smallest system formed. This system is easy to install detection, software function is perfect, reliable operation, the advantages of high accuracy. This paper discusses the single-chip microcomputer control by the LCD digital display system, and expounds the basic principle of the Keil software to realize the system using design and simulation and the system applied fields.
