摘要
介绍了ST7920的功能和应用,并给出了ST7920与MCU的多种接口方式。重点介绍了ST7920的指令集以及基于其初始化编程步骤,最后以显示4行汉字为例,给出了相应的汇编程序。
At first,the functions and applications of ST7920 are simply introduced in this paper,and many kinds of interfaces between ST7920 and MCU are given.The instruction set of ST7920 and its initialization programming steps based on ST7920 are presented.Finally the corresponding brief assembly program by the example of displaying four-lines Chinese characters are given.
