摘　　要：以往Proteus中利用LCD显示汉字,需要先用汉字取模软件取模、然后拷贝汉字点阵数据到程序,步骤繁琐,而且只能显示预备好的汉字,十分不方便。为解决这一问题,将汉字库HZK16以64kB大小划分成4个区间,并分别加载到Proteus的4个AT24C512存储器中,设计了数据读取电路,利用Proteus中的PG160128液晶模块实现了汉字显示。实验结果表明,采用AT24C512存储汉字库文件的方式可以方便地显示汉字,打破了只能显示固定汉字的模式,提高了开发效率。It was inconvenient to display Chinese characters by the use of LCD in Proteus in the past.Firstly,the character module software must be used to pick up the character models,and then,the dot matrix data would be copied to the program.Not only the steps were cumbersome,but also only inherent characters could be showed.In this paper,Chinese character library HZK16 was loaded in program memory AT24C512 in Proteus,the data acquisition circuit was designed,and the display of Chinese characters was realized by using LCD PG160128 in Proteus.Experimental results show that it is convenient to display Chinese characters by the use of AT24C512 storing Chinese character library,the mode has been broken that only fixed Chinese characters can be showed,and the development efficiency is improved.
