摘要
在以计算机为核心的应用系统中,人机界面必不可少。为解决人机界面设计中存在的用户操作的便捷性、工程造价、硬/软件操作的简便性、压缩硬/软件规模等难题,采用字符型液晶模块设计了以MCS 51系列微控制器为CPU的人机界面的显示部分。给出了硬件接口的详实设计以及软件设计;并对用字符型液晶模块设计人机界面过程中常见的问题进行分析,给出解决方法。由于字符型液晶模块具有性价比高、硬件接口简单、软件操作灵活方便、显示内容丰富、体积小、低功耗等特点,特别适合袖珍仪器、仪表或便携式设备等规模不大的中、小型应用系统的开发与研制。
Human-Computer interface is indispensable in the application system with computer as the core. In order to solve the problems of the convenience of user operation, the engineering costs, the convenience of hardware/software operation and control the scale of hardware/software in the design of human-computer interface. The character type LCD module is used to design display part of the man-machine interface which use the MCS-51 microcontroller as CPU. The detail design of the hardware interface and the software design is provided, and the common problems during the design of the human-computer interface with character type LCD module is analyzed and the solution is given out. The character type LCD module has the advantages of high cost effective, simple hardware interface, flexible and convenient software operation, rich display content, small volume and low power consumption. For this reason, it is very appropriate for the development of the small and medium application system, such as pocket instrument and portable equipment.
