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1616点汉字，和128个168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
 
}

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；




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
