Question

LED点阵屏目前广泛应用于各种公共场合，例如在户外广告媒体中越来越多的传统灯箱、霓红灯等都被LED显示屏替代，具有广阔的市场前景。本文主要阐述了基于单片机的LED显示屏控制系统的设计原理与实现，详细的介绍了下位机系统的软硬件设计方法，其中系统的硬件设计主要以AT89C52单片机作为核心器件，由74ls595和74ls164驱动四个分辨率8x8的LED点阵显示屏的扫描显示。软件设计才用了C语言，并通过模块化设计方法实现了上下左右滚动显示汉字、图形、字符等功能

Answer 1

LED lattice screen which are widely used in various public places, such as more and more traditional light box in the outdoor advertising media, such as strobe lights are replaced by LED display, has broad market prospects. This article mainly expounds the LED display control system design based on single chip microcomputer principle and implementation, detailed introduces the hypogyny machine system's software and hardware design method of the system's hardware design mainly take AT89C52 single chip microcomputer as the core device, driven by 74 ls595 and 74 ls164 four 8 by 8 LED dot matrix display screen resolution scan display. Software design using C language, and through the modular design method realizes the up and down left and right scrolling display Chinese characters, graphics, characters, etc

Answer 2

LED dot matrix display is widely used in various public places , such as in outdoor advertising media more and more traditional light boxes, neon lights , etc. are replaced LED display , and has broad market prospects. This paper describes a microcontroller-based LED display control system design principles and implementation of a detailed introduction of the next -bit machine system hardware and software design methods, in which the system 's hardware design of AT89C52 microcontroller as the core device , driven by a four 74ls595 and 74ls164 a resolution of 8x8 LED dot matrix display scan display . Software design only with the C language, and a modular design approach to achieve the vertical and horizontal scrolling display Chinese characters, graphics, characters , etc.

Answer 3

Nowadays,LED dot matrix screen is widely used in various public places，For example, in outdoor advertising media ，more and more traditional lamp box, neon lights were substitutes for LED moniter, so It has a wide horizon of development .This paper mainly describes the design principle and implementation of LED
display screen control system based on MCU，and introduced the detail description of the hardware and software design method of the lower computer system.In which the design of the hardware system use the AT89C52 microcontroller as the main core device.LED dot matrix display screen by 74ls595 and 74LS164 drive four resolution 8x8 scanning display.Only microsoft design used language C,and realize the scroll up and down around the display Chinese characters, graphics, characters and other functions Through modular design method.

Answer 4
