摘　　要：采用点阵式LCD作为电磁阀检测仪的显示终端,介绍了一种在C语言环境下,在液晶显示屏上实现多级嵌套菜单显示并通过键盘和单片机通信的简便方法。给出了一个结构紧凑、实用的程序模型,编写了实际中经常用到的一些程序,这些程序已在伟福E6000/L仿真器中编译通过,在实际的检测过程中能让LCD正确显示电磁阀检测仪采集的电压、电流、压降等实时数据,还能很好地嵌套显示电磁阀检测仪其他的一些相关信息,显示图像稳定、清晰。A kind of dot-matrix LCD was applied to the solenoid detector as display terminal.A simple method was introduced to achieve multi-level nested menu display on the LCD screen and communicate with the micro controller through keyboards in the C language environment.The paper presented a compact and practical model of the process,and compiled some procedures used at every turn,which got across in the Weifu-E6000/L simulator successfully,and could make LCD display the real-time data accurately in the actual detection process,such as voltage,current,air pressure,which collected by solenoid detector.And this LCD can display some other related information about the solenoid detector nested,and the images are stable and clear.
