摘要
研究了图形显示液晶模块的汉字显示方法,通过外扩的EEPROM存储整个汉字库,将其作为外部数据存储器进行寻址,以MC68332单片机为例,介绍了根据汉字的机内码计算区位码,通过汉字区位码寻址汉字库进行字模提取的液晶显示汉字取模新方法,并给出对应的C程序。该方式能大大简化系统的维护,提高程序的可读性和效率。
The methods of showing Chinese characters on graphic liquid crystal display module were studied. This paper described method of placing whole Chinese characters library in EEPROM and using it as external RAM. Taking MC68332 as an example, it introduced the new method of picking up Chinese character models on LCD through area position code according to Chinese character＇s code inside computer, listed corresponding C program. The method can reduce maintenance degree of system greatly, increase program＇s readability and efficiency.
