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。

LCD12864（T6963）驱动程序

液晶显示模块的应用一、结构特点内藏T6963C 的液晶显示模块上已经实现了T6963C 与行、列驱动器及显示缓冲区RAM 的接口，同时也已用硬件设置了液晶屏的结构(单双屏、数据传输方式、显示窗口长度、宽度等等。

我们常用的液晶显示模块一般都是单屏结构，因此我们这里只讨论单屏结构的液晶显示模块。

内藏T6963C 的单屏结构点阵图形液晶显示模块的方框图如下：二、T6963C 的特点(1) T6963C 是点阵式液晶图形显示控制器它能直接与8 位微处理器接口；(2) T6963C 的字符字体可由硬件或软件设置，其字体有4 种5X8 、6X8、7X8、8X8；(3) T6963C 的占空比可从1/16 到1/128；(4) T6963C 可以图形方式、文本方式及图形和文本合成方式进行显示，以及文本方式下的特征显示，还可以实现图形拷贝操作等等；(5) T6963C 具有内部字符发生器CGROM，共有128 个字符。

T6963C 可管理64K显示缓冲区及字符发生器CGRAM，并允许MPU 随时访问显示缓冲区，甚至可以进行位操作。

　三、该类液晶模块的管脚定义见下表:说明:对于单电源模块，标志为V0/POFF。

当该管脚为高或悬空时，内部DC/DC功能开启；为低时，内部DC/DC 功能关闭。

该功能可用作屏幕保护和休眠方式。

如果用其直接替代双电源模块，该管脚直接悬空即可。

四、液晶显示模块的供电说明1. 如果您所选用的液晶模块是双电源（VDD/V0）供电的就需要提供一个负电压（液晶驱动电压V0/VEE），用以调节对比度，接在液晶模块的V0 引脚上。

因为液晶材料的物理特性，液晶的对比度会随着温度的变化而相应变化，所以，您加的负电压值应该随温度作相应的调整，大致是温度变化10°C 电压变化1伏左右。

为满足这一要求您要选择较大值的负电源，然后做一个温度补偿电路，或者安排一个电位器调整负电压值。

例如对于QH12864T-HT-LED04，当室温（VDD=5V）时，V0=-10.5V，如果要用到-20°C，液晶驱动电压将要变到V0=-14.5V，再考虑到负载消耗所以您提供的负电源应该为-16V 左右。

LCD12864液晶驱动编程指南

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

D=1:开显示(DISPLAY ON) 意即显示器可以进行各种显示操作 D=0:关显示(DISPLAY OFF) 意即不能对显示器进行各种显示操作 2.设置显示起始行(DISPLAY START LINE)

所谓页地址就是 DDRAM 的行地址，8 行为一页,模块共 64 行即 8 页,A2~A0 表示 0~7 页。读写数据对地址没有影响,页地址由本指令或 RST 信号改变复位后页地址为 0。页地址与 DDRAM 的对应关系见 DDRAM 地址表。 4.设置 Y 地址(SET Y ADDRESS)
此指令的作用是将 A5~A0 送入 Y 地址计数器，作为 DDRAM 的 Y 地址指针。在对 DDRA M 进行读写操作后，Y 地址指针自动加 1,指向下一个 DDRAM 单元。
//将值转成字符串
void LcmPutAsc( uchar asc ); //显示一个 5×7 的 ASC 字符
void LcmPutstr( uchar row,uchar y,uchar * str );
//在设定位置显示字符串
void LcmPutpoint( uchar ro,uchar lie,uchar colour ); //在设定位置显示一个点
5.读状态(STATUS READ)
当 R/W=1 D/I=0 时,在 E 信号为“H”的作用下，状态分别输出到数据总线(DB7~DB0)的相应位。
BF:
前面已叙述过(见 BF 标志位一节)。
ON/OFF: 表示 DFF 触发器的状态（见 DFF 触发器一节）。
RST:
RST=1 表示内部正在初始化，此时组件不接受任何指令和数据。

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。注意在 V0 的电压是在一个很小的范围有效。我的就是在-2.2——-2.5 这个范围。仔细调节 V0 和地之间的电阻使 V0 上的电压在 2.3V。
