玩转12864液晶--显示字符
在我们常用的人机交互显示界面中，除了数码管，LED，以及我们之前已经提到的LCD1602之外，还有一种液晶屏用的比较多。
相信接触过单片机的朋友都知道了，那就是12864液晶。
顾名思义，12864表示其横向可以显示128个点，纵向可以显示64个点。
我们常用的12864液晶模块中有带字库的，也有不带字库的，其控制芯片也有很多种，如KS0108T6963，ST7920等等。
在这里我们以ST7920为主控芯片的12864液晶屏来学习如何去驱动它。
(液晶屏采用金鹏的OCMJ4X8C)关于这个液晶屏的更多信息，请参考它的DATASHEET，附件中有下载。
我们先来了解一下它的并行连接情况。
下面是电路连接图从上面的图可以看出，液晶模块和单片机的连接除了P0口的8位并行数据线之外，还有RS,RW,E等几根线。
其中R/S是指令和数据寄存器的选择控制线(串行模式下为片选)，R/W是读写控制线(串行模式下是数据线)，E是使能线(串行模式下为时钟线)。
通过这几根控制线和数据线，再结合它的时序图，我们就可以编写出相应的驱动程序啦。
看看并行模式下的写时序图：根据这个时序图，我们就可以写出写数据或者写命令到LCD12864液晶的子程序。
读时序图如下：根据这个时序图我们就可以从LCD12864液晶模块内部RAM中读出相应的数据，我们的忙检测函数就是根据这个时序图写出来的。
以及后面章节中讲的画点函数等都要用到读时序。
有了这两个时序图，然后我们再看看OCMJ4X8C的相关指令集，就可以编写出驱动程序了。
这里要注意的是指令集分为基本指令集和扩充指令集，其中扩充指令集主要是与绘图相关，在此后的章节中会有相应的介绍。
下面让我们根据这些编写出它的驱动程序吧。
我的硬件测试条件为：STC89C516(11.0592MHz) + OCMJ4X8C实际显示效果图片如下：程序部分如下，请结合液晶模块的DATASHEET看程序，这样能够更加快速的弄懂程序的流程。

引用12864液晶原理分析3他山之石2010-07-21 20:52:05 阅读7 评论0 字号：大中小小峰的12864液晶原理分析3一、ST7920控制IC的LCD12864实现反白显示从使用手册上可知，扩展指令里的0x03+行号即可实现反白对应行。
但是ST7920 控制器的128×64 点阵液晶其实原理上等同256×32 点阵，第三行对应的DDRAM 地址紧接第一行；第四行对应的DDRAM 地址紧接第二行。
所以128×64 点阵的液晶执行反白功能时实用意义不大，因为用户对第一行执行反白显示操作时，第三行必然也反白显示；第二行反白，第四行也必然反白。
其实还是有办法做到单行反白的，解决方法就是混用图形显示和字符显示。
其理论支持在于：在ST7920中，字符显示的DDRAM和图形的GDRAM是相互独立的，而最后显示到液晶上的结果，是两个RAM中数据的异或。
具体来说：假如某个点上，绘图RAM的没有绘图（数据为0），而字符RAM上有点阵（数据为1），那么异或的结果就是1，也就是说正常显示字符；当字符上RAM没有点阵的时候，异或的结果是0，自然也就不显示了。
假如该点上绘图RAM绘图了（数据为1），当字符RAM上有点阵（数据为1时），异或的结果为0，效果就是反白显示；如果字符RAM没有点阵（数据为0时），异或结果为1，效果就是显示绘图的背景。
所以，如果要在某个地方反白显示，那么就在该点绘图并且写字，如果要取消反白，就重新用全0擦掉那个地方的绘图！这样一来可以实现任何地方、任意大小的反白显示，反而比原指令中的单行反白的功能更好更强大。
二、对于整屏既有图象又有文本，则可以用两种方式实现：1、首先文本DDRAM写入要写的字符，其余全部空格（即0X00），然后再在没有字符的地方（即非点亮的晶格中，0X00）绘入图象。
DDRAM与GDRAM异或后就可以整屏实现图象与文本。
