仪器仪表操作的智能化是时代的要求,文中结合国人看汉字的习惯,提出了一种利用单片机和液晶点阵显示模块显示汉字的方法和多种汉字滚屏方案,介绍了单片机AT89C51与液晶显示模块12232A的接口原理及其应用,对设计中的有关问题进行说明。从实验运行情况看,该模块汉字显示清晰、实时、信息量大、滚屏美观,中文界面友好,大大方便了使用。
The intelligent operation of instrumentation is the requirement of the times. In this paper, combining the Chinese habit of seeing Chinese characters, a method of displaying Chinese characters and a variety of Chinese character scrolling schemes is proposed by using single chip microcomputer and liquid crystal dot matrix display module. The single chip AT89C51 and liquid crystal display module 12232A interface principle and its application, the design of the related issues are described. From the experimental run situation, the module shows a clear Chinese characters, real-time, large amount of information, rolling beautiful, friendly Chinese interface, greatly facilitate the use.
