12864无字库液晶显示程序

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。

点阵LCD12864的显示原理（不带字库）在数字电路中，所有的数据都是以0和1保存的，对LCD控制器进行不同的数据操作，可以得到不同的结果。

对于显示英文操作，由于英文字母种类很少，只需要8位（一字节）即可。

而对于中文，常用却有6000以上，于是我们的D OS前辈想了一个办法，就是将ASCII表的高128个很少用到的数值以两个为一组来表示汉字，即汉字的内码。

而剩下的低128位则留给英文字符使用，即英文的内码。

那么，得到了汉字的内码后，还仅是一组数字，那又如何在屏幕上去显示呢？这就涉及到文字的字模，字模虽然也是一组数字，但它的意义却与数字的意义有了根本的变化，它是用数字的各位信息来记载英文或汉字的形状，如英文的'A'在字模的记载方式如图1所示：图1 “A”字模图而中文的“你”在字模中的记载却如图2所示：图2 “你”字模图12864点阵型LCD简介12864是一种图形点阵液晶显示器,它主要由行驱动器/列驱动器及128×64全点阵液晶显示器组成。

可完成图形显示，也可以显示8×4个(16×16点阵)汉字。

LCD12864（不带字库）LCD12864（不带字库）其实看了本版的1602教程以后很容易就可以掌握12864了。

刚才看到有网友要12864教程，俺就把博客里以前练习的一个程序弄过来，算作参考吧。

不足之处请见谅。

这个程序浪费了我很多时间，因为我一直没有找到datasheet，12864的型号实在太多了。

为了这个程序，我在网上找了很多相关的例程，但大多都是C语言写的，可惜俺没学过C，用起来不顺手，遂将其转成汇编，但是转后，程序运行不正常，郁闷啊。

好不容易找个汇编的吧，又写得很乱，没有头绪，没有datasheet，看起来很费劲，最后终于找到一个相关的datasheet，这才完成这个程序。

总结一下：与其费力分析别人的程序，不如看datasheet自己写。

下面总结一下datasheet。

→↑←ONE→且看datasheet：12864点阵型LCD简介12864是一种图形点阵液晶显示器,它主要由行驱动器/列驱动器及128×64全点阵液晶显示器组成。

可完成图形显示，也可以显示8×4个(16×16点阵)汉字。

在使用12864LCD前先必须了解以下功能器件才能进行编程。

12864内部功能器件及相关功能如下：1. 指令寄存器(IR)IR是用于寄存指令码，与数据寄存器数据相对应。

当D/I=0时，在E信号下降沿的作用下，指令码写入IR。

2．数据寄存器(DR)DR是用于寄存数据的，与指令寄存器寄存指令相对应。

当D/I=1时，在下降沿作用下，图形显示数据写入DR，或在E信号高电平作用下由DR读到DB7∽DB0数据总线。

DR和DDRAM之间的数据传输是模块内部自动执行的。

3．忙标志：BFBF标志提供内部工作情况。

BF=1表示模块在内部操作，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 READ指令，可以将BF读到DB7总线，从检验模块之工作状态。
