摘要
在实际应用中,特别是在需要实时大量输入汉字的显控处理应用中,利用传统单片机显控设计方法是无法实现的;通过对汉字内码的分析,给出硬件汉字库的制作方法,提出针对一、二级汉字库编码检索的拼音输入检索方法,利用Philips P89C5 1RD2单片机为核心处理芯片,设计一种具有通过键盘用汉语拼音输入法输入汉语拼音,利用相应程序通过编码检索,在显控系统中实时输入汉字,并在L CD上显示或通过RS2 32串口输出汉字点阵数据的方法。
In the actual application, especially in needing large input what Chinese characters of display and control application,making use of the machine of traditional MCU to display and control application to design the method can′t be realized;by analysing Chinese ISN,manufacturing method of the hardware Chinese characters is given;the input method of first and second class Chinese characters libraries,making use of the Phillip MCU P89C51RD2 to handle the chip for core,and design an input method by using the keyboard to input the Chinese phonetical phabetic characters,with the program by coding search with Chinese language index,in display and control system input the Chinese characters on realtime,and show on the LCD or output Chinese characters point data to RS 232.
