说明：

带中文字库的LCD128X64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。

LCD12864有多种接线方式，依据数据传输的方式可以分为8位并口、4位并口以及串口接线三种方式。串口接线只需要接一根数据线，节约了端口，因此，我们采用串口接线的方式。

实验目的：

在本例中，我们将利用LCD12864模块输出特定字符，以及让LCD显示图片。

器材：

Stduino UNO/Nano;杜邦线；LCD12864

电路连接：

示例一：输出特定字符代码：

#include <LCD12864.h>
Lcd12864 lcd12864;
void setup()
{
// put your setup code here, to run once:
lcd12864.initial(A2,A1,A0,9);// EN,RW,RS,PSB
lcd12864.clean();//清屏
delay(20);
}
void loop()
{
// put your main code here, to run repeatedly:
lcd12864.clean();//清屏
lcd12864.ShowString(0,2,"思特诺");//从第0行第2列开始输出"思特诺"内容
lcd12864.ShowString(1,2,"Stduino");//从第1行第2列开始输出"Stduino"内容
lcd12864.ShowString(3,1,"创建时间：年");//从第3行第1列开始输出"创建时间：年"内容
lcd12864.ShowInt(3,6,2020);//从第3行第6列开始输出2020内容
lcd12864.ShowDouble(2,1,123.43);//从第2行第1列开始输出123.43内容
delay(1000);//延时1000ms
}

复制代码

示例二：显示128×64像素大小的图画。

首先我们需要利用Krita或者其他绘图软件制作一幅128×64大小的黑白bmp格式的图片。接下来，将其导入到取字模软件，获得Stduino IDE可识别的每一像素点的信息。随后利用DrawFullScreen()方法，将像素点的信息传递给LCD上的每一位地址，即可绘制全屏的像素图。

第一步：在Krita中新建128×64大小的文档，并绘制像素图，保存为BMP文件：

因为今年有千年一遇的新智彗星访问地球，因此画了一幅彗星的图片，嘿嘿，算作补上没有看到的遗憾吧。

第二步，利用取字模软件，将BMP图转化为像素信息：

参数确认：选择C语言以及输出大小（128×64），点击参数确认；

载入图片：点击载入图片，选择刚才你制作好的图片，上部黑白取反依据需要提前选择好。

数据保存：载入图片没有问题之后，选择“数据保存”，信息以保存在新的文件当中。

利用Hbuider或者Notepad++等文本编译器打开保存的文件，大括号内的数据就是我们需要的内容：

第三步：编写代码。

把前面的数据复制到一个无符号字符数组中，再利用DrawFullScreen()方法处理即可。

代码如下：

#include <LCD12864.h>
Lcd12864 lcd12864;
unsigned char newWise[]={ //你的图片的数据
