对于ATC51单片机的16*16点阵的汉字仿真,该设计能够简单的呈现出各个中文字符。这次的设计不包含硬件处理,主要是进行在PROTEUS上的仿真处理和KEIL的程序编程

摘  要:随着社会的发展进步,LED的发展也愈发成熟,现在它已经被普遍的运用在社会的各个方面,例如在高楼上,店的门面上,保险管的指示灯,汽车上的尾灯头灯和台灯等等,还有许多方面,就不一一列举了。LED的被使用有很多方面的因素,首先因为它能够方便的被应用,而且它的成本也不是很高,其次它呈现出来的灯光品质和灯光的质量更为优秀,更加美观的呈现出所要展示的东西,让人们感受到不一样的享受。LED显示屏是几个或者更加多个的发光二极管按照方形或者某个图形组合封装组成的,常见的用来展示各种信息,比如时间或者图片等等。此次我的毕设是对于ATC51单片机的16*16点阵的汉字仿真,该设计能够简单的呈现出各个中文字符。这次的设计不包含硬件处理,主要是进行在PROTEUS上的仿真处理和KEIL的程序编程。58116

LED dot matrix display microcontroller PROTEUS simulation design

ABSTRACT:With the development and the progress of society, the development of LED has become more mature, and now it has been frequentlyused in all aspects of society, such as the tower, on the facade of the store, indicator light on safety tube ,the taillights and headlights on the car ,table lamps and so on, I'm not going to go through anymore examples .LED is used in many ways, first because it can easily be applied, and its cost is not very high, secondly it presents the quality light and the quality of light is more outstanding and showing the things more beautiful. The LED let people feel different. The LED display screen is composed of a plurality of light diodes which are according to a square or a graphic combination package .It common has been used to display all kinds of information, such as time or picture and so on. This time I design is based on the 16*16 ATC51 of Chinese characters simulation. This display can be easily displayed various characters. The design does not include hardware processing, mainly for the simulation on the PROTEUS and KEIL programming.
