题目 基于 5 1 单片机的 L ED 显示屏 摘要: 由于科技的快速发展，LED 显示屏已经是在大街上随处可见的应用了，它的应用已经普及到社会中的方方面面。LED 点阵具有无限级联的特点，以一个个小的显示屏可以拼接出一块大的显示屏，在许多场合都可以见到它的身影，不仅因为 LED 显示屏可使呈现的信息更为直观，更为重要的是这种显示方式非常方便且具有较高的性价比，能够给人以视觉上的享受，更能给人一种美的享受。LED显示屏是一个犹发光二极管按照一定的形式排列封装形成的，可显示广告，图文信息等。本设计是基于 STC89C51 单片机的 16*16 点阵显示屏，该 LED 显示屏能实现分辨率 16*16 的汉字显示，简单的显示图像。该设计包含硬件设计、然健设计以及系统调试等，中需要简单的将硬件模块和软件模块进行组合即可实现显示功能。本文设计的基于 51 单片机的 LED 显示屏可实现预期功能，具有功耗低、操作简单、精度高等诸多优势。关键词：点阵显示屏 级联 51 单片机IAbstract: Due to the rapid development of technology, LED display screen has been widely used in the streets., and its application has been popularized in every aspect of society. LED dot matrix has the characteristics of infinite cascade, with a small display can piece together a large display, on many occasions can see the figure of it, is not only the application of it to make something appear more beautiful, more important is that its application is convenient, cost is low, in addition to can give a person visual impact, more can give a person a kind of beautiful enjoyment. LED displays are arranged in a matrix by several light-emitting diodes, usually used to display advertising, graphics and other information. This design is based on the 16*16 point array display of STC89C51 single chip. The LED display can display the Chinese characters of 16*16 and display the image simply. The design includes hardware, software, debugging, etc., which can realize the expansion of the display scree...
