摘要
介绍了一种基于AT89S52微处理器、键控显示模式、多汉字显示的显示模块设计方法。对AT89S52的内部功能及使用高128字节RAM时的寻址方式进行说明。给出了四汉字显示模块的硬件电路原理图、主程序流程图以及中断显示流程图。
The design method of display module base on the AT89S52 microcontroller, display mode controlled by keyboard and showing several Chinese characterses are introduced in the paper.The in- ternal function and the addressing mode for the high 128B RAM of the AT89S52 are explained.The basic circuit diagram,the main program flow chart and the display interrupt flow chart of four Chinese characterses display module are also given.
