12864液晶屏幕使用说明及程序

12864使用说明一、串/并接口1.1 串口接口管脚信号*注释1：如在实际应用中仅使用并口通讯模式，可将PSB 接固定高电平。

*注释2：模块内部接有上电复位电路，因此在不需要经常复位的场合可将该端悬空。

*注释3：如背光和模块共用一个电源，可以将模块上的JA、JK 用焊锡短接。

1.2 并行接口管脚信号*注释1：如在实际应用中仅使用并口通讯模式，可将PSB 接固定高电平。

*注释2：模块内部接有上电复位电路，因此在不需要经常复位的场合可将该端悬空。

*注释3：如背光和模块共用一个电源，可以将模块上的JA、JK 用焊锡短接。

二、模块主要硬件构成说明控制器接口信号说明：2.1、RS，R/W的配合选择决定控制界面的4种模式：2.2、E信号●忙标志BFBF 标志提供内部工作情况.BF=1 表示模块在进行内部操作,此时模块不接受外部指令和数据.BF=0 时, 模块为准备状态,随时可接受外部指令和数据.利用STATUS RD 指令,可以将BF 读到DB7 总线,从而检验模块之工作状态.●字型产生ROM（CGROM）字型产生ROM（CGROM）提供8192 个此触发器是用于模块屏幕显示开和关的控制。

DFF=1 为开显示（DISPLAY ON),DDRAM 的内容就显示在屏幕上，DFF=0 为关显示（DISPLAY OFF)。

DFF 的状态是指令DISPLAY ON/OFF 和RST 信号控制的。

●显示数据RAM（DDRAM）模块内部显示数据 RAM 提供 64×2 个位元组的空间，最多可控制 4 行 16 字（64 个字）的中文字型显示，当写入显示数据 RAM 时，可分别显示 CGROM 与CGRAM 的字型；此模块可显示三种字型，分别是半角英、数字型(16*8)、CGRAM 字型及 CGROM 的中文字型。

三种字型的选择，由在 DDRAM 中写入的编码选择，在0000H—0006H 的编码中（其代码分别是0000、0002、0004、0006 共4 个）将选择 CGRAM 的自定义字型，02H—7FH 的编码中将选择半角英数字的字型，至于A1 以上的编码将自动的结合下一个位元组，组成两个位元组的编码形成中文字型的编码BIG5（A140—D75F），GB（A1A0-F7FFH）。

12864液晶显示器(ST7920)显示程序(并口) 附字模软件作者：纪小年16 七月2009 时间：下午10:25 and have 10 条评论前两天写了一个ST7920控制12864显示的串口程序，今天瞎逛的时候发现了这个超强悍的并口程序，转载一下。

来源：CnChina做了比较详细的注释，看不懂的可以问我。

下面的图片中12864所显示的logo就是我用这个程序得到的。

中文图形显示控制芯片ST7920的原理与应用

中文图形显示控制芯片ST7920的原理与应用摘要：介绍了一种具有４位／８位并行、２线／３线串行等多种接口方式，且内含国标简体中文字库的图形点阵液晶显示控制模块。

同时介绍了该芯片的性能特点及接口方式，给出了相应的硬件电路及汉字显示程序。

关键词：串／并接口；控制模块；中文图形显示１概述ＳＴ７９２０是台湾矽创电子公司生产的中文图形控制芯片，它是一种内置１２８×６４－１２汉字图形点阵的液晶显示控制模块，用于显示汉字及图形。

该芯片共内置８１９２个中文汉字（１６×１６点阵）、１２８个字符的ＡＳＣＩＩ字符库（８×１６点阵）及６４×２５６点阵显示ＲＡＭ（ＧＤＲＡＭ）。

为了能够简单、有效地显示汉字和图形，该模块内部设计有２ＭＢ的中文字型ＣＧＲＯＭ和６４×２５６点阵的ＧＤＲＡＭ绘图区域；同时，该模块还提供有４组可编程控制的１６×１６点阵造字空间；除此之外，为了适应多种微处理器和单片机接口的需要，该模块还提供了４位并行、８位并行、２线串行以及３线串行等多种接口方式。

利用上述功能可方便地实现汉字、ＡＳＣＩＩ码、点阵图形、自造字体的同屏显示，所有这些功能（包括显示ＲＡＭ、字符产生器以及液晶驱动电路和控制器）都包含在集成电路芯片里，因此，只要一个最基本的微处理系统就可以通过ＳＴ７９２０芯片来控制其它的芯片。

ＳＴ７９２０的主要技术参数和显示特性如下：电源：ＶＤＤ(－２．７～＋５．５Ｖ)＋５Ｖ(内置升压电路，一般无需负压)；功耗：正常模式：４５０μＡ，睡眠模式：３μＡ，低功耗模式：３０μＡ；显示内容：１２８列×６４行；显示颜色：黄绿；显示角度：６：００钟直视；ＬＣＤ类型：ＳＴＮ；与ＭＣＵ接口：８位并行／３位串行；配置有ＬＥＤ背光显示功能；带有自动启动复位按钮(ｒｅｓｅｔ)；图1软件功能设置：画面清除、光标显示／隐藏、光标归位、显示打开／关闭、显示字符闪烁、光标移位、显示移位、垂直画面旋转、反白显示、液晶睡眠／唤醒、关闭显示、自定义字符、睡眠模式等。
