Ⅱ 如何用c51单片机和8255扩展芯片设计16*16LED点阵显示屏设计
一般建议用2片3-8译码器做片选信号(控制16个口),然后再用两个P口(也是16脚)进行数据传输,这样就能实现16*16的数据显示了,建议PROTUES仿真,网上这样的例子很多,但仿真时可能效果不如实际开发板上效果好。
这里有个视频教材,protues 仿真实现,很好很强大,希望对你有用。
http://v.youku.com/v_show/id_XMjYwOTgzMjky.html
另外 如果有试验箱,就会有指导手册和例程,多问问老师。
Ⅲ 基于51单片机的旋转led屏中,红外接收管还有红外发射管的作用是什么
做为刷新的零点。转速不是绝对稳定的,延时不是绝对准确的。无论程序执行到哪里,只要收到信号就会以此为零点开始刷屏,物理位置不会变。
旋转led是由直流电机的高速旋转,带动了若干个LED,由单片机芯片控制LED的亮灭,利用人眼的视觉暂留原理,从此就可以在空中形成各种图案。
51单片机是对所有兼容Intel 8031指令系统的单片机的统称。该系列单片机的始祖是Intel的8031单片机,后来随着Flash rom技术的发展,8031单片机取得了长足的进展,成为应用最广泛的8位单片机之一,其代表型号是ATMEL公司的AT89系列,它广泛应用于工业测控系统之中。很多公司都有51系列的兼容机型推出,今后很长的一段时间内将占有大量市场。51单片机是基础入门的一个单片机,还是应用最广泛的一种。需要注意的是52系列的单片机一般不具备自编程能力。
Ⅳ 基于51系列单片机的LED显示屏开发技术 这本书怎么样
是国内第一本针对铁电单片机的书籍,为初学铁电单片机或是希望了解该单片机的读者提供了较为全面的资料和开发例程。此外还对通用LED显示屏上位机控制软件设计、LED显示屏控制系统常用时钟芯片DS1302、温度传感器DS18B20等模块控制程序和硬件电路进行分析和讲解。这些内容是作者近几年来部分开发工作的实践总结,有些是根据实际生产产品的提炼和推广。
Ⅳ 求基于51单片机的LED点阵显示屏系统的设计与实现的论文
给你一个源代码吧,自己分析,用汇编写的。本人编写后亲试过,只要一片C8052S的最少系统就能工作 驱动市售$5.0单元板(32*64)。

Ⅶ 基于51单片机的led点阵显示屏设计原理与电路图
51和led点阵一般要用到动态扫描的方式,也就是显示的画面不是一下子就把整个画面的内容全部显示出来,而是逐行显示的,只不过显示的频率超过了50HZ
甚至更高,所以我们看起来是“不晃眼”的。也就是说,屏幕显示是由行显示组成的(即子程序)。行显示再细分就是有位显示组成,不过行显示就不用逐位显示了。其实行显示就是串入并出,即行显示是一下子就显示出来的。
我给你传一份资料你参考一下。。。。。。
