12864液晶屏串口驱动程序

12864液晶屏串口驱动程序代码

12864液晶屏驱动采用4_Wire-SPI串口驱动方式，可有效的减少IO口的占用，方便使用调试，本程序的代码驱动IC为ST7565R,是基于STC89C53RC的12864串行模式的程序，硬件电路连接只需要5根线：RS、 SDA、 SCLK、RES、CS 。

程序已经调试通过，很好用。代码如下：

无字库12864液晶的驱动方法

无字库12864液晶的驱动方法在制作单片机系统时，一般都需要用显示器件来显示单片机的工作状态并显示输出结果，如LED、数码管和液晶显示器等。LED最简单，但能给出的信息很少。数码管能清晰地显示数字和部分字母，但是耗电较大，不适合使用电池供电的装置。常见的液晶显示器有段式液晶、字符液晶和图形液晶等。其中，段式液晶最省电，但对于通用显示使用起来不很方便，只能显示固定式数字或符号，而且需要专用驱动电路或特殊的单片机。字符液晶（如1602）用得比较多，容易和单片机配合，但是一般都需要5V工作电压，虽然现在也有3V就可以工作的模块，但是体积还是较大，而且只能显示数字和西文字符，无法显示图形和汉字。点阵液晶模块既可以显示ASCII字符，又可以显示汉字和图形，相对于前面几种，具有更大的灵活性，所以使用得越来越多。不过常用的图形液晶因为显示面积增加，体积比字符液晶（如1602）更大，价格也更贵。初学者要注意的是，12864图形点阵液晶随着厂家设计使用的驱动芯片不同，驱动程序有所区别，不像1602那样基本通用。几种常见的12864图形点阵模块 12864点阵液晶模块分为带汉字库和不带汉字库两大类，目前带汉字库的通常是ST7920驱动，它可以工作在汉字字符方式和图形点阵方式，很多制作都用它，如果需要显示较多汉字，用它最为方便。在显示汉字数量很少的场合，我们可以使用更加廉价的、不带字库的点阵液晶模块，这正是本文重点介绍的。它们的控制电路有KS0108和ST7565两种：KS0108很简单，一共只有7条指令，可是它没有串行接口；ST7565有20多条指令（最常用的也就几条），有串行接口，可选串行或并行工作。KS0108和ST7565的指令和上述带字库的ST7920区别较大，所以初学者买液晶时一定要搞清楚是哪种驱动电路。即使同样的驱动电路，不同厂家或者不同型号的产品，具体细节仍可能不同。例如有的片选信号是高电平有效，有的却是低电平有效，有的把显示区分为左右两半分别选取，有的却不加区分。所以使用前要仔细看厂家说明，如果没有，就要看液晶模块背面给出的具体型号，根据这个型号去查找使用手册。笔者最近在淘宝网上搜寻到一款12864的图形点阵液晶，只有4cm宽、3.5cm高，显示面积为3.2cm宽、1.95cm高，非常小巧。更加难能可贵的是它可以在3V低电压工作，很适合我们制作小型便携装置。该液晶模块型号是SP12864FPD-12CSBE，由北京集粹电子设备公司出品，它的外形见图1。

常见液晶驱动芯片详解

本文主要是介绍一些常用的LCD驱动控制IC的型号，方便学习或正在使用的LCD的朋友能够更好地编写LCD的驱动程序。因此各位朋友在选择LCD液晶模块的时候，在考虑到串行，还是并行的方式时，可根据其驱动控制IC的型号来判别，当然你还需要看你选择的LCD 模块引脚定义是固定支持并行，还是可选择并行或串行的方式。一、字符型LCD驱动控制IC 市场上通用的8×1、8×2、16×1、16×2、16×4、20×2、20×4、40×4等字符型LCD，基本上都采用的KS0066作为LCD的驱动控制器二、图形点阵型LCD驱动控制IC 1、点阵数122×32－－SED1520 2、点阵数128×64 （1）ST7920/ST7921，支持串行或并行数据操作方式，内置中文汉字库（2）KS0108，只支持并行数据操作方式，这个也是最通用的12864点阵液晶的驱动控制IC （3）ST7565P，支持串行或并行数据操作方式（4）S6B0724，支持串行或并行数据操作方式（5）T6963C，只支持并行数据操作方式 3、其他点阵数如192×6 4、240×64、320×64、240×128的一般都是采用T6963c驱动控制芯片

4、点阵数320×240，通用的采用RA8835驱动控制IC 这里列举的只是一些常用的，当然还有其他LCD驱动控制IC，在写LCD驱动时要清楚是哪个型号的IC，再到网上去寻找对应的IC数据手册吧。后面我将慢慢补上其它一些常见的. 三 12864液晶的奥秘 CD1601/1602和LCD12864都是通常使用的液晶，有人以为12864是一个统一的编号，主要是12864的液晶驱动都是一样的，其实12864只是表示液晶的点阵是128*64点阵，而实际的12864有带字库的，也有不带字库的；有5V电压的，也有~5V(内置升压电路)；归根到底的区别在于驱动控制芯片，常用的控制芯片有ST7920、KS0108、T6963C等等。下面介绍比较常用的四种 (1)ST7920类这种控制器带中文字库，为用户免除了编制字库的麻烦，该控制器的液晶还支持画图方式。该类液晶支持68时序8位和4位并口以及串口。 (2)KS0108类这种控制器指令简单，不带字库。支持68时序8位并口。 (3)T6963C类这种控制器功能强大，带西文字库。有文本和图形两种显示方式。有文本和图形两个图层，并且支持两个图层的叠加显示。支持80时序8位并口。
