基于51单片机的12864LCD显示驱动摘要：利用51单片机对12864LCD显示屏进行驱动，并令其显示动态及静态图像。

可使用4位/8位并行、2线或3线串行多种接口方式，拥有多种字库的点阵图形液晶显示模块；接口方式灵活，操作指令简单、方便，可构成全中文人机交互图形界面。

可以显示汉字，也可完成图形显示；电压、功耗较低；硬件电路结构与显示程序都要简洁，同时价格也略低于相同点阵的图形液晶模块。

其内部含有国标一级、二级简体中文字库的点阵图形液晶显示模块；其显示分辨率为128×64，内置8192个16*16点汉字，和128个16*8点ASCII字符集。

图1 TS12864液晶实物图该模块接口方式灵活和操作指令简单、方便，可构成全中文人机交互图形界面。

可以显示8×4行16×16点阵的汉字。

也可完成图形显示，有低电压低功耗的特点。

由该模块构成的液晶显示方案与同类型的图形点阵液晶显示模块相比，不论硬件电路结构还是显示程序都要简洁得多，且该模块的价格也略低于相同点阵的图形液晶模块。

本设计讲采用STC89C52对TS128X64进行驱动，设计并制作LCD驱动电路，使其可通过按键切换LCD的显示内容，并且实现对数字，汉字，英文以及图片的显示，滚屏，以及动画功能。

1.硬件设备STC89C52是STC公司生产的一种低功耗、高性能CMOS8位微控制器，具有8K 在系统可编程Flash存储器。

STC89C52使用经典的MCS-51内核，但做了很多的改进使得芯片具有传统51单片机不具备的功能。

在单芯片上，拥有灵巧的8 位CPU 和在系统可编程Flash，使得STC89C52为众多嵌入式控制应用系统提供高灵活、超有效的解决方案。

具有以下标准功能：8k字节Flash，512字节RAM，32 位I/O 口线，看门狗定时器，内置4KB EEPROM，MAX810复位电路，3个16 位定时器/计数器，4个外部中断，一个7向量4级中断结构（兼容传统51的5向量2级中断结构），全双工串行口。
