LCD12864的驱动

LCD12864驱动LCD12864在市面上主要分为两种，一种是采用st7920控制器的，它一般带有中文字库字模，价格略高一点。

另一种是采用KS0108控制器，它只是点阵模式，不带字库。

很可惜，我的这块就是KS0108控制器不带汉字库的，不过不打算用它专门显示文本，也就无所谓了。

LCD12864模块的20个引脚定义如下：1。

Vss 逻辑电源地2。

VDD 逻辑电源正5v3。

V0 LCD驱动电压4。

RS 数据/指令选择：高电平为数据，低电平为指令5。

R/W 读/写选择：高电平为读数据，低电平为写数据6。

E 读写使能，高电平有效，下降沿锁定数据7。

DB0 数据输入输出引脚8。

DB1 数据输入输出引脚9。

DB2 数据输入输出引脚10。

DB3 数据输入输出引脚11。

DB4 数据输入输出引脚12。

DB5 数据输入输出引脚13。

DB6 数据输入输出引脚14。

DB7 数据输入输出引脚15。

CS1 片选择号，低电平时选择前64列16。

CS2 片选择号，低电平时选择后64列17。

RET 复位信号，低电平有效。

18。

VEE 输出－15v电源给V0提供驱动电源19。

A 背光电源LED正极20。

K 背光电源LED负极具体电路图如下：制做如下：接口说明：装上12864具体的电路还是两个电阻。

一个背光限流电阻。

一个液晶驱动电压调节电阻。

背光电阻还是任何时候在19、20脚与电源之间串上个100欧电位器接上电源。

调节电位器到合适亮度。

具体值最好是到调试完程序能够正常显示后再将阻值确定换成固定电阻。

液晶驱动电压的调整在数据线、电源线接好的前提下是在Vee(-15v)和地之间接一个电位器。

中间接V0，通过调节电位器来调节V0上的电压。

当V0上为-15V时为全暗(液晶显示为全黑)。

当V0为0V 时为全亮。

调节电位器使屏幕从全暗刚好变到亮时，便可进行程序的调试。

待屏幕显示正常后，进行对比度的细调，然后测量这两边的阻值在地和V0之间、V0和Vee之间换成两个固定电阻焊上就好了。

12864(ST7565P)液晶驱动

12864（ST7565P）液晶驱动显示概念含有ST7565P 芯片的液晶，是没有文库支持的功能，但是没有就没有啦！液晶可以给我画画，那么它就是好东西了。

液晶的“显示”，液晶的“扫描次序”全部都与CGRAM分配有很大的关系。

我们先了解“扫描次序”吧。

宏观上一副液晶是“64高x 128宽”。

微观上由芯片ST7565P驱动的一副12864 液晶是由“8个8 高x 128宽的页”组成。

至于液晶的“扫描次序”就与4个命令有关系。

上图表示了，当命令为0xA0列扫描是“自左向右”，如果命令式0xA1列扫描是“自右向左”。

总归，这两个命令控制了“列扫描次序”除了控制列扫描的命令以外，当然还有控制“页扫描次序”的命令。

如上图，命令0xC0 控制页扫描是“从下至上”，然而命令0xc8 控制页扫描“又上至下”。

无论页扫描的次序是“从上至下”还是“从下至上”，然而每一页的列填充，都是“低位开始高位结束”关于列扫描就有列填充的问题。

我们知道每“一页”都是由“8 高x 128宽”组成。

换句话说，这里没有“行扫描”的概念，因为“一页”都是由“一个字节数据，列填充128次”成为一页。

如上图中所示。

假设“页扫描次序”是由上至下，填充的值是0x0f，那么经过128次的“列扫描”以后，一页的扫描结果会是如上图所示。

关于ST7565P 芯片，命令，和液晶扫描它们之间的关系而已，我们简单来总结一下：（一）CGRAM分布是由8页组成。

（二）每一页是由一个字节填充和128次列扫描组成。

（三）列扫描次序与命令0xA0 与0xA1有关。

（四）页扫描次序与命令0xC0 与0xC8 有关。

（五）列填充字节的高位低位关系与页扫描命令有关。

（六）不存在行扫描概念。

上图所示是“页扫描”由上至下，“列扫描”由左至右，列填充值是0x0f。

在CGRAM分布方面。

CGRAM 可以说是由8 bits x 1024 words，如果以“页”去分配，也就是说8 page x 8 bits x 128 words ，那么“页”的偏移量就是128。

二、显示图片
显示图片和显示汉字的原理是一样的，只不过是大小的问题！现在我们就以一张 128*64 分辨率的图片进行取模。取模图片：
现在我们主要看一下显isplay_BMP(uchar a[][64])//显示图形的左边部分 { uchar i,j; for(j=0;j<8;j++) { SelectScreen(1); Set_page(j); Set_column(0); for(i=0;i<64;i++) //显示左屏 { write_LCD_data(a[2*j][i]);//每隔一行取一次数组中的数据 } SelectScreen(2); Set_page(j); Set_column(0); for(i=0;i<64;i++) //显示右屏 { write_LCD_data(a[2*j+1][i]);//每隔一行取一次数组中的数据 } } } 取出图片的数据是二维数组形式！注意，液晶是先显示左半屏，再显示右半屏，但是取数组中的元素是逐个往下取出的，所以是对于一个半屏而言，每隔一行取数组中的元素，而隔去的那一行是另一个半屏要取的数据！这一点一定要注意。还有一点要补充的就是，这个取模软件只能识别 BMP 和 ICO 格式的单色图片，如果我们选择的图片不是 128*64 大小的话，可以通过软件将其改成 128*64 大小的，如果我们直接用软件取模的话，显示的会是乱码，解决办法是我们可以通过 windows 自带的画图工具，什么也不做修改，将大小设置好的图片另存为 BMP 单色文件就行了，然后再用取模软件取模就 OK 了，=^_^ = ！算了，给大家截个图

LCD12864液晶驱动编程指南

LCD12864液晶驱动编程指南
1.连接硬件：
2.初始化液晶：
在开始使用液晶之前，需要进行初始化。

初始化过程包括设置液晶的
工作模式、显示模式和其他参数。

通过向液晶发送一系列的指令，可以完
成初始化过程。

3.编写驱动程序：
液晶驱动程序的主要目的是将需要显示的内容以及液晶的控制指令发
送给液晶屏。

根据液晶屏的通信方式，可以采用单片机的IO口直接控制
液晶屏，也可以通过SPI或I2C等接口芯片间接控制。

4.显示图形：
5.显示文本：
除了图形外，液晶还可以显示文本。

可以通过设置显示位置和发送需
要显示的文本来实现。

6.更新显示：
当需要更新液晶上的内容时，可以通过重新设置显示的内容和刷新液
晶来实现。

可以定时刷新液晶，或者通过检测外部事件来触发刷新。

7.扩展功能：
除了基本功能外，还可以实现一些扩展功能，如显示动画、滚动显示、倒计时等。

只需要根据需求编写相应的代码即可实现。

总结：
注意事项：
在编写驱动程序时，需要注意及时更新液晶上的内容，避免频繁刷新导致的卡顿现象。

同时，为了保证程序的可移植性，可以将液晶驱动程序与其他功能模块进行分离，便于代码的维护和移植。

LCD12864原理与应用(源程序+原理图+proteus仿真)

LCD12864原理与应用1、LCD12864简介：LCD12864分为两种，带字库的和不带字库的，不带字库的液晶显示汉字的时候可以选择自己喜欢的字体。

而带字库的液晶，只能显示GB2312字体，当然也可以显示其他的字体，不过是用图片的形式显示。

下面介绍不带字库的LCD12864,以Proteus中的AMPIRE128×64为例，如下图所示，它的液晶驱动器为KS0108。

引脚功能：引脚符号状态引脚名称功能，输入芯片片选端，都是低电平有效CS1=0开左屏幕，CS1=1关左屏幕CS2=0开右屏幕，CS2=1关右屏幕RS 输入数据/命令选择信号RS=1为数据操作，RS=0为写指令或读状态RW 输入读写选择信号R/W=1为读选通，R/W=0为写选通E 输入读写使能信号在E下降沿，数据被锁存(写)入液晶，在E高电平期间，数据被读出DB0—DB7 三态数据总线数据或指令的传送通道输入复位信号，低电平时复位复位时，关闭液晶显示，使显示起始行为0，可以跟单片机的复位引脚RST相连，也可以直接接VCC，使之不起作用V0 液晶显示器驱动电压-Vout -10V LCD驱动负电压与带字库的液晶不同，此块液晶含有两个液晶驱动器，每块驱动器都控制64*64个点，分为左右两个屏幕显示，总共为128*64个点（即有128×64个点）。

这就是为什么AMPIRE128*64有CS1和CS2两个片选端的原因。

此液晶有8页，一页有8行点阵点，左右各64列，共128列。

如下图所示：2、LCD12864中的几条重要指令（一）行(line)设置命令:由此可见显示的起始行地址为0XC0，共64行，有规律地改变起始行号，可以实现滚屏效果。

（二）页(page)设置指令:起始页地址为0XB8，因为液晶有64行点，分为8页，每页就有8行点。

（三）列(column)地址设置指令每块驱动器的列地址都是从0X40到0X7F，共64列，所以此液晶共有128列点。
