摘　　要：在我国,基于嵌入式系统的智能仪器中,中文人机交互界面是必不可少的功能,某些系统还要求中文文本的输入。给出了通用计算机键盘在智能仪表中的接口,同时也给出了以ST7920为控制器的带汉字字库的液晶显示模块的接口方法及原理。采用该方法可大大提高智能仪表的汉字输入与显示功能,为智能仪表提供了一种汉字输入与显示解决方案。Chinese man-machine conversation interface is therefore necessary and important unto the intelligent instrument based on embedded system in our country,the Chinese text must be input in some system.In this paper,the interface of the computer keyboard in common use and the intelligent instrument is given,and the interface and the principle of Chinese characters display control based on the LCD module controlled with the ST7920 is introduced too,at the same time.It can enhance the intelligent instrument function of Chinese characters input and display by using this technology,and provide a kind of resoluble plan of Chinese characters input and display for the intelligent instrument.
