在需要实时大量输入汉字的显示控制处理应用中，利用传统单片机实现显示控制的设计方法是较难实现的。带汉字字库的液晶模块的使用使得小容量ROM单片机的大量汉字信息输入与显示成为可能。提出了针对汉字字库编码的二级索引拼音输入检索方法,介绍了以ST7920作为控制器的带汉字字库的液晶显示模块的接口方法及汉字显示和控制原理，给出了通用计算机键盘在单片机中的串行接口，采用该技术可大大增强单片机的汉字输入功能。为小容量ROM单片机的大批量汉字信息处理提供了一种汉字输入解决方案。 Abstract: It is difficult to realize Chinese characters input method based on the embedded system by using the traditional design method of display control. It is possible to input and display Chinese characters based on the embedded system with the ROM of small content by using the LCD module with Chinese characters.Chinese characters input method of the quadric index recall in allusion to Chinese characters code is brought forward.The interface and the principle of Chinese characters display control based on the LCD module controlled with the ST7920 is introduced too.The serial interface of the computer keyboard in common use and the embedded system is given at the same time. It can enhance the embedded system function of Chinese characters input by using this technology, and provide a kind of Chinese characters input scheme for the embedded system with small capacity ROM.

针对船舶气象仪保障维修而设计的船舶气象仪测试系统，包括信息处理终端、主仪器检测模块、传感器检测模块，各个模块都采用基于AVR单片机的嵌入式系统，模块之间通过CAN总线进行通信。结果表明，船舶气象仪测试系统能够快速检测船舶气象仪故障，与单纯依靠人工方式排查故障相比，故障检测时间缩短了60%以上。 Abstract: The test system of ship meteorological instrument was developed to satisfy the maintenance of ship meteorological instruments，which composed of information processing terminal， testing module of main instrument and testing module of sensors. Each of these modules included an embedded system based on microcontroller of AVR series and communicated with other module by CAN bus. The results show that the test system can judge the fault of ship meteorological instrument quickly and shorten the fault detection time as much as 60% compared with simple manual troubleshooting.
