带字库LCD12864自定义图形、汉字显示

带字库的LCD12864自定义图片、汉字显示
一、将图片修改成128*64像素
1、打开win7自带的画图软件，载入图片（图片不满足128*64）
2、点击重新调整大小（或者图片处右击鼠标），如下设置，保持纵横比不勾选。

3、图片另存为，选择单色位图。

二、LCD12864用ZIMO21软件取模（BMP图片）
1、基本设置里面设置LCD的大小（如果图片像素就是128*64就不需要设置，直接打开）
2、打开BMP图片（黑白）
3、发现图片偏小，不足128*64，此时生成的数据就缺少128*64个点，显示会照成错误，需要修改一下图片大小。

改成128*64
3、直接调入128*64图片
4、设置参数，如下
5、取模选择C51格式
6、显示效果
三、PCtoLCD2002图片取模设置
四、PCtoLCD2002汉字取模设置（根据程序而定）
1、汉字取模参数设置
2、显示效果如下。

LCD12864显示屏程序汉子显示顺序对应的数值错误解决方案

LCD12864显示屏程序汉子显示顺序对应的数值错误
解决方案
STC12C5A60S2调试LCD12864显示汉字。

问题描述
每次显示汉字，第一次汉字总是显示不对。

code u8 string[4]=
{
"床前明月光",
"疑是地上霜",
"举头望明月",
"低头思故乡",
};
第一行显示总是为：
42前明月光
另外换成其他任意汉字，第一个字总是不对，后面的字有概率不对。

原因分析：
一开始怀疑时序有问题，不停的去网上找别人写的例程，拿过来调试发现还是不行。

然后怀疑是KEIL编码有问题，但是调到GB2312还是老样子。

后来又怀疑是液晶屏问题，重新找了个换下还是不行。

程序发给同事，他运行正常。

然后我就想起来可能是我板子供电不正常，丢了原装适配器，只是用一根线链接的USB 5V供电，之前用示波器测试发现电源有时候波动很厉害，导致数据脚数据出错。

解决方案：
于是直接将数据脚改成推挽输出，成功。

教程用的都不是增强型的芯片，并不会设置IO口。

由于暂时没有适配器，无法检验没有设置成推挽输出在我的开发板上是否正常。

lcd12864程序流程图

lcd12864 程序流程图
我们常用的人机交互显示界面中，除了数码管，LED，以及我们之前已经提到的LCD1602 之外，还有一种液晶屏用的比较多。

相信接触过单片机的朋友都知道了，那就是12864 液晶。

顾名思义，12864 表示其横向可以显示128 个点，纵向可以显示64 个点。

我们常用的12864 液晶模块中有带字库的，也有不带字库的，其控制芯片也有很多种，如KS0108 、T6963，ST7920 等等。

在这里我们以ST7920 为主控芯片的12864 液晶屏来学习如何去驱动它。

（液晶屏采用金鹏的OCMJ4X8C）。

lcd12864 液晶说明：
我们先来了解一下它的并行连接情况。

下面是电路连接图：
上面的图可以看出，液晶模块和单片机的连接除了P0 口的8 位并行数据线之外，还有RS，RW，E 等几根线。

其中R/S 是指令和数据寄存器的选择控制线（串行模式下为片选），R/W 是读写控制线（串行模式下是数据线），E 是使能线（串行模式下为时钟线）。

通过这几根控制线和数据线，再结合它的时序图，我们就可以编写出相应的驱动程序啦。

看看并行模式下的写时序图：。

能够显示 8× 4 行 16× 16 点阵的汉字 . 也可达成图形显示 . 低电压低功耗是其又一明显特色。

由该模块构成的液晶显示方案与同种类的图形点阵液晶显示模块对比，无论硬件电路构造或显示程序都要简短得多，且该模块的价钱也略低于同样点阵的图形液晶模块。

LCD12864液晶显示器中文说明(DOC)

主要技术参数和显示特性:电源：VDD 3.3V~+5V(内置升压电路，无需负压)；显示内容：128列× 64行显示颜色：黄绿显示角度：6：00钟直视LCD类型：STN与MCU接口：8位或4位并行/3位串行配置LED背光多种软件功能：光标显示、画面移位、自定义字符、睡眠模式等二、外形尺寸1.外形尺寸图2.二、模块引脚说明电源地(GND)：0V工作温度(Ta)：0～60℃(常温) / -20～75℃（宽温）三、接口时序模块有并行和串行两种连接方法（时序如下）：8位并行连接时序图MPU写资料到模块MPU从模块读出资料、串行连接时序图2串行数据传送共分三个字节完成：第一字节：串口控制—格式11111ABCA为数据传送方向控制：H表示数据从LCD到MCU，L表示数据从MCU到LCDB为数据类型选择：H表示数据是显示数据，L表示数据是控制指令C固定为0第二字节：(并行)8位数据的高4位—格式DDDD0000第三字节：(并行)8位数据的低4位—格式0000DDDD串行接口时序参数：(测试条件：T=25℃VDD=4.5V)四、用户指令集1、当模块在接受指令前，微处理顺必须先确认模块内部处于非忙碌状态，即读取BF 标志时BF 需为0，方可接受新的指令；如果在送出一个指令前并不检查BF 标志，那么在前一个指令和这个指令中间必须延迟一段较长的时间，即是等待前一个指令确实执行完成，指令执行的时间请参考指令表中的个别指令说明。

2、“RE ”为基本指令集与扩充指令集的选择控制位元，当变更“RE ”位元后，往后的指令集将维持在最后的状态，除非再次变更“RE ”位元，否则使用相同指令集时，不需每次重设“RE ”位元。

具体指令介绍：1、清除显示 CODE ：功能：清除显示屏幕，把DDRAM 位址计数器调整为“00H ” 2、位址归位 CODE ：功能：把DDRAM 位址计数器调整为“00H ”，游标回原点，该功能不影响显示DDRAM 3、位址归位 CODE ：功能：把DDRAM 位址计数器调整为“00H ”，游标回原点，该功能不影响显示DDRAM 功能：执行该命令后，所设置的行将显示在屏幕的第一行。

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。

今天终于完成了12864带字库液晶模块的图象和中英文字母显示，图象显示显示了自己的一副照片，呵呵，还认得出是自己，开心啊。

硬件连接方式是：并口直接访问。
