摘要
本文主要介绍了基于Proteus单片机显示屏的硬件与软件设计过程,设计中利用简单的外围电路来控制16×80大小的显示屏,显示屏能够以动态扫描的方式同时显示六个16×16大小的点阵汉字,可以通过修改程序代码来改变显示的内容,字幕可以实现滚动功能,而且滚动速度能根据要求进行调节。所显示的汉字字码存储在外部数据存储器中,存储器的容量可以根据所要显示字数的要求进行扩展。最后,在Proteus软件的基础上对结果进行了仿真,仿真结果表明,在单片机显示领域的设计开发中,Proteus软件具有重要的使用价值,可以大幅缩短开发周期,节约开发成本。
This paper introduces display design process about hardware and software based on Proteus in single chip microcomputer.We use a simple external circuit to control the display screen,which size is 16 × 80.The display screen also can display the size of the five 16 × 16 dot matrix Chinese characters by a dynamic scan mode,and we can modify the code to change the content of the display,subtitles can achieve scrolling function and the scroll speed can be adjusted according to requirements.The Chinese character code stored in external data memory,the capacity of data memory is expanded according to the requirements of Chinese characters we want to show.Finally,the circuit which has been designed was simulated on the basis of Proteus.Simulation results show the Proteus software application is an important practical value in the design of single chip microcomputer,which will greatly shorten the development cycle and save development costs.
