Design and Implementation of Pinyin Input Method for Low Performance Single Chip Microcomputer

介绍一种应用于低性能单片机的拼音输入法设计方案。在主控芯片内部资源不足(如FLASH和RAM容量较小、IO端口较少)的情况下,利用自带中文字库的液晶显示模块、占用IO端口较少的矩阵键盘和巧妙的内码存储方式,再结合软件灵活处理数据的优势,实现中文汉字的拼音输入。

This paper introduces a design scheme of Pinyin input method applied to low performance single chip microcomputer.In the case of insufficient internal resources(such as small capacity of flash and ram,less IO port)in the main control chip,the LCD module with Chinese character library,matrix keyboard occupying less IO port and ingenious internal code storage mode are used to realize the Pinyin input of Chinese characters combined with the advantages of flexible data processing of software.
