12864图形液晶显示模块与51系列单片机接口技术

单片机与可编程器件液晶显示模块以其微功耗、体积小、显示内容丰富、模块化、接口电路简单等诸多优点得到广泛应用。

液晶显示模块分字符型和点阵型两种，前者只能显示常用的字符，点阵型液晶显示模块除显示字符外还能显示各种图形和汉字。

目前，尽管液晶显示模块种类繁多，但其结构及控制方法是一样的，本文以常用的１２８×６４液晶显示模块为例介绍液晶显示模块的工作原理及其与５１系列单片机的接口技术。

１２８６４图形液晶显示模块１２８６４液晶显示模块表示横向有１２８点，纵向有６４点，可显示１６×１６中文字４行，每行８个字，外形和引脚排列如图１所示。

１．　引脚功能引脚功能如表１所示。

２．　显示ＤＤＲＡＭ与Ｘ地址、Ｙ地址排列方式ＤＤＲＡＭ是模块自带的存储单元，用来存放图形信息或数据，ＤＤＲＡＭ存储单元与液晶显示屏之间存在一一对应关系，数据为１表示显示选择，对应屏幕亮；数据为０表示显示非选择，对应屏幕不亮。

ＤＤＲＡＭ与Ｘ、Ｙ地址和显示位置的关系如表２所示。

３．１２８６４液晶显示模块指令１２８６４液晶显示模块基本操作指令如表３所示。

（１）读取状态字当Ｒ／Ｗ＝１，Ｄ／Ｉ＝０时，在Ｅ信号为高的作用下，状态字分别输出到数据总线上。

状态字是了解模块当前工作状态的唯一的信息渠道，在每次对模块操作之前，都要读出状态字判断ＢＵＳＹ是否为“０”。

若不为“０”，则计算机需要等待，直至ＢＵＳＹ　＝０为止。

（２）显示开关设置Ｄ＝１开显示，Ｄ＝０关显示。

（３）显示起始行设置指令表中ＤＢ５～ＤＢ０为显示起始行的地址，取值在０～３ＦＨ（１～６４行）范围内，它规定了显示屏上最顶一行所对应的显示存储器的行地址。

（４　）　页面地址设置页面地址是ＤＤＲＡＭ的行地址。

８行为一页，ＤＤＲＡＭ共６４行即８页，ＤＢ２￣ＤＢ０表示０￣７页。

（５）列地址设置列地址是ＤＤＲＡＭ的列地址。

共６４列，１２８６４图形液晶显示模块与５１系列单片机接口技术・湖南邵阳学院电气信息工程学院江世明・摘要文章以１２８×６４液晶显示模块为例，系统地介绍了１２８６４图形液晶显示模块的结构特征、指令系统、工作时序及与５１系列单片机接口技术、编程方法。
