流水灯电路设计.doc

摘要: 本次设计要求采用可编程逻辑器件实现一个流水灯控制电路, 8个LED 灯能连续发出三种不同的流水显示形式,先是 8个LED 灯从左到右依次点亮,左边亮四个,右边亮四个,最后从中间往两边亮、两边往中间亮,实现了灯光的移动和闪亮效果,特别是用于夜晚装饰,可以使我们的生活更为丰富多彩,同时也发挥出可编程器件的灵活性特点,可以改动电路实现多种效果。流水灯是一串按一定的规律像流水一样连续闪亮,流水灯控制是可编程控制器的一个应用,其控制思想在工业控制技术领域也同样适用。流水灯控制可用多种方法实现, 但对现代可编程控制器而言,基于 EDA 技术的流水灯设计也是很普遍的。关键字: EDA,CPLD,LED, 状态机; Abstract: The design requirements by using the programmable logic device implements a water light control circuit, eight LED lights out for three different water display form, The first 8 LED lights litup sequentially from left to right, the left four bright bright,right four, finally from the middle to both sides, both sides to the middle of the brightlight , realize the middle of mobile and ablaze effect, especially used for decoration, night can make our life more rich and colorful, also play a programmable device of flexibility, can change characteristics DuoZhong circuit implementation effect. Water lamp isa string of according to certain rules for shining, like water flowing water light control isa programmable controller, the control application in industrial control technology thought also applies. Water light control method can be used DuoZhong, but for modern programmable controller based on the technology for EDA water lamp design also is mon.
