LCD12864原理与应用

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。

lcd12864中文资料汇总（12864引脚说明及功能lcd12864简介带中文字库的128X64是一种具有4位/8位并行、2线或3线串行多种接口方式，内部含有国标一级、二级简体中文字库的点阵图形液晶显示模块；其显示分辨率为128×64，内置8192个16*16点汉字，和128个16*8点ASCII字符集。

利用该模块灵活的接口方式和简单、方便的操作指令，可构成全中文人机交互图形界面。

可以显示8×4行16×16点阵的汉字。

也可完成图形显示。

低电压低功耗是其又一显著特点。

由该模块构成的液晶显示方案与同类型的图形点阵液晶显示模块相比，不论硬件电路结构或显示程序都要简洁得多，且该模块的价格也略低于相同点阵的图形液晶模块。

12864LCD驱动原理

12864LCD驱动原理
在初始化阶段，我们需要进行一系列的设置和配置以确保显示屏正常
工作。

这包括发送指令序列，设置显示模式、偏置电压、对比度和字符显
示等参数。

通过这些初始化设置，我们可以确保每个像素点的状态都能清
晰可见。

在数据写入阶段，我们可以向特定的位置写入数据以控制像素点的亮
灭状态。

通过选择特定的行和列，在给定的位置上点亮或熄灭单个像素点。

这通常通过提供特定格式的数据来实现，其中每个字节表示8个像素点的
状态。

1.硬件连接：液晶显示屏与控制器之间通过平行数据总线进行连接。

控制器提供行、列选择信号以及数据和控制信号。

还需要通过其他引脚来
提供电源和对比度调节信号。

2.初始化：在驱动液晶显示屏之前，我们需要发送一些特定的初始化
命令以设置液晶显示屏的参数。

这些命令包括清屏，设置显示模式、偏置
电压、对比度等。

3.数据写入：在初始化完成后，我们可以开始向液晶显示屏写入数据
以控制像素点的状态。

数据可以通过给定的坐标来确定，其中选择特定的
行和列。

写入数据时，需要同时提供数据信号以及行和列选择信号。

4.控制信号：除了数据信号外，还需要提供行和列选择信号以确定要
控制的像素点位置。

行选择信号（Y0~Y63）选择要操作的行，而列选择信
号（X0~X127）选择要操作的列。

DSP-液晶显示屏(LCD)实验

班级学号姓名同组人实验日期室温大气压成绩实验四液晶显示屏（LCD）实验一、实验目的1、掌握液晶的使用方法；2、掌握液晶信号之间时序的正确识别和引入。

二、实验设备1、一台装有CCS2000软件的计算机；2、插上2812主控板的DSP实验箱；3、DSP硬件仿真器。

三、实验原理本实验箱采用的液晶接口在DSP的数据总线上，由于DSP是十六位总线，液晶是八位总线，所以DSP的高八位悬空。

液晶的结构框图如下：1、把2812模块小板插到大板上，打开液晶模块的电源开关；2、在CCS2000环境中打开本实验的工程编译Example_lcd.pjt，成输出文件，通过仿真器把执行代码下载到DSP芯片；3、运行程序，液晶上会循环显示预定内容；4、参考源代码，自行修改程序，实现不同的显示模式。

五、实验结果实验现象如下图所示：通过本次CCS环境下LCD12864液晶模块显示的仿真实验，让我了解并熟悉了CCS软件的安装和调试方法，DSP实验箱下载调试的步骤以及CCS环境下的DSP的C语言程序编写方法，对于12864液晶模块控制程序的编写也有了更深的认识，对今后DSP的进一步学习奠定了应用基础。

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
