点阵显示屏是利用发光二极管组成的平面式显示屏。由于LED具有发光率高、使用寿命长等优点,在国内外得到了广泛的应用。本设计使用AT89C51为微控制器,8X8点阵显示屏为显示模块,通过连接线组合一个显示屏。通过单片机控制显示需要的图案。基于AT89C51单片机的点阵屏显示设计,本文介绍了一款以单片机AT89C51为控制器的LED点阵显示屏系统的设计。该系统可实现数字的显示和动态特效显示。
Dot matrix display is the use of light-emitting diodes consisting of flat-panel display. As the LED has a high luminous rate, long life, etc., at home and abroad have been widely used. The design uses the AT89C51 microcontroller, 8X8 dot matrix display for the display module, a display through the cable combination. Through the single-chip control display the desired pattern. Based on the AT89C51 single-chip dot matrix display design, this article describes a microcontroller AT89C51 as a controller LED dot matrix display system design. The system can achieve digital display and dynamic effects display.
