說明：
帶中文字庫的LCD128X64是一種具有4位/8位并行、2線或3線串行多種接口方式，內部含有國標一級、二級簡體中文字庫的點陣圖形液晶顯示模塊。其顯示分辨率為128×64，內置8192個16*16點漢字，和128個16*8點ASCII字符集。利用該模塊靈活的接口方式和簡單、方便的操作指令，可構成全中文人機交互圖形界面。可以顯示8×4行16×16點陣的漢字。
LCD12864有多種接線方式，依據數據傳輸的方式可以分為8位并口、4位并口以及串口接線三種方式。串口接線只需要接一根數據線，節約了端口，因此，我們采用串口接線的方式。

實驗目的：
在本例中，我們將利用LCD12864模塊輸出特定字符，以及讓LCD顯示圖片。

器材：
Stduino UNO/Nano;杜邦線；LCD12864

電路連接：


示例一：
輸出特定字符代碼：
#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,"思特諾");//從第0行第2列開始 輸出"思特諾"內容
    lcd12864.ShowString(1,2,"Stduino");//從第1行第2列開始 輸出"Stduino"內容
    lcd12864.ShowString(3,1,"創建時間：    年");//從第3行第1列開始輸出"創建時間：    年"內容
    lcd12864.ShowInt(3,6,2020);//從第3行第6列開始 輸出2020內容
    lcd12864.ShowDouble(2,1,123.43);//從第2行第1列開始 輸出123.43內容
   
    delay(1000);//延時1000ms

}

示例二：顯示128×64像素大小的圖畫。
首先我們需要利用Krita或者其他繪圖軟件制作一幅128×64大小的黑白bmp格式的圖片。接下來，將其導入到取字模軟件，獲得Stduino IDE可識別的每一像素點的信息。隨后利用DrawFullScreen()方法，將像素點的信息傳遞給LCD上的每一位地址，即可繪制全屏的像素圖。

第一步：在Krita中新建128×64大小的文檔，并繪制像素圖，保存為BMP文件：

因為今年有千年一遇的新智彗星訪問地球，因此畫了一幅彗星的圖片，嘿嘿，算作補上沒有看到的遺憾吧。


第二步，利用取字模軟件，將BMP圖轉化為像素信息：
參數確認：選擇C語言以及輸出大小（128×64），點擊參數確認；


數據保存：載入圖片沒有問題之后，選擇“數據保存”，信息以保存在新的文件當中。


利用Hbuider或者Notepad++等文本編譯器打開保存的文件，大括號內的數據就是我們需要的內容：


第三步：編寫代碼。
把前面的數據復制到一個無符號字符數組中，再利用DrawFullScreen()方法處理即可。
代碼如下：
  1. #include <LCD12864.h>

  3. Lcd12864 lcd12864;
  4. unsigned char newWise[]={  //你的圖片的數據
