注意，这个链接的LCD12864工作电压是3.3V的！如果您需要5V的，请联系客服。使用说明书+51单片机C语言例子程序下载地址：http://ishare.iask.sina.com.cn/f/24519482.html(请复制到浏览器打开)视频教程如下：http://www.tudou.com/programs/view/W2X36A6W9DE/(请复制到浏览器打开)全新(不带排针排母)，带中文字库。本店是厂家一级代理，质优价廉！ I请注意，由于本店利润低，技术人员成本高，本液晶模块不提供技术支持，请淘友们自行学习，提高自学能力。我们的液晶模块在出厂前都经过严格的测试，质量有保证！由于我们的LCD12864是全新的，上面不带排针排母的，如果需要，请联系客服。焊接注意事项：由于液晶模块带有精密元件，焊接时，请尽量使用质量好的烙铁焊接。因为部分低价劣质烙铁带有很高的静电，容易损坏精密元件。如果实在没有好质量的烙铁，可以用一条导线将烙铁与自来水管（如果你家的自来水管是铁的话）连到一起，或者和墙壁的铁门铁窗连到一起。这样虽然不是严格的接地，但是也可以起到一定的作用，保护我们的液晶模块。LCD12864接口定义如下：并口模式如下：第1脚：VSS为地电源第2脚：VDD接3.3V正电源第3脚：（请特别注意，3.3V的LCD12864请让此引脚悬空！我们内部已经集成可调电阻已经调好，悬空就可以正常使用了。）V0为液晶显示器对比度调整端，接正电源时对比度最弱，接地电源时对比度第4脚：RS为寄存器选择，高电平时选择数据寄存器、低电平时选择指令寄存器。第5脚：R/W 当R/W和E都为高电平时，数据被读到DB0～DB7；当R/W为低电平，E从高电平变为低电平，DB0～DB7的数据被写到IR或DR寄存器。第6脚：E 使能信号第7～14脚：DB0～DB7 为8位双向数据线。第15脚：PSB 并行/串行选择。当PSB为高电平时是并行模式；当PSB为低电平时，是串行模式。如果您的液晶屏第15脚是CS1，请点击这里。第16脚：NC 空脚。如果您的液晶屏第16脚是CS2，请点击这里。第17脚：/RESET复位脚。低电平有郊。第18脚：VOUT LCD驱动电压输出端，可不接。第19脚：A 背光灯电源正极，接+3.3V。第20脚：K 背光灯电源负极，接地。I串口模式如下：第1脚：VSS为地电源第2脚：VDD接3.3V正电源第3脚：V0为液晶显示器对比度调整端，接正电源时对比度最弱，接地电源时对比度第4脚：CS 片选信号，高电平有效。第5脚：SID 串行数据输入端。第6脚：CLK 串行同步时钟。第15脚：PSB 并行/串行选择。当PSB为高电平时是并行模式；当PSB为低电平时，是串行模式。第17脚：/RESET复位脚。低电平有郊。第19脚：A 背光灯电源正极，接+3.3V。第20脚：K 背光灯电源负极，接地。尺寸图如下：

本店的3.3V LCD12864只有蓝屏的是有现货。如果您需要黄绿屏的，量大可以订货。蓝屏和黄绿屏的尺寸、功能等都是一样的，就只是显示的效果不同。最终的包装效果图，完全地保护您的宝贝！

参考电路如下：如果发现LCD12864的显示效果不理想或者没有显示，请调节接到第3脚的可调电阻。参考的51单片机程序如下：

请注意电路的接口不同，程序需要相应地修改。再次声明，本店不提供技术支持，请淘友们自行学习！#include <reg51.h>
