無(wú)字庫(kù)LCD12864顯示8個(gè)漢字后面不顯示，為什么？

在無(wú)字庫(kù)LCD12864上面寫(xiě)字的時(shí)候，寫(xiě)了八個(gè)字后，后面的不顯示了，然后一步一步調(diào)，發(fā)現(xiàn)超過(guò)8個(gè)就不顯示了。
顯示程序如下：
void lcd_display_chinese(uchar screen,uchar page,uchar col,uint mun)
{             //screen:選擇屏幕參數(shù)，page:選擇頁(yè)參數(shù)0-3，col:選擇列參數(shù)0-3，mun:顯示第幾個(gè)漢字的參數(shù)
      int a;
      mun=mun*32;
      select_screen(screen);                                  //選屏
      W_CMD(0xb8+(page*2));                                  //頁(yè)：一頁(yè)8點(diǎn)行
      W_CMD(0x40+(col*16));                                  //列：一列1點(diǎn)列
      for (a=0;a<16;a++)
      {
            W_DATA(chinese[mun++]);                         //一個(gè)字16x16

      }
      W_CMD(0xb8+(page*2)+1);                                  //兩頁(yè)一行
      W_CMD(0x40+(col*16));                                  //行列指針自加1
      for (       a=0;a<16;a++)
      {
            W_DATA(chinese[mun++]);

      }
}

主函數(shù)如下：
void main()
{
      initLCD();                                                 //LCD初始化
      clear_screen(0);                                           //LCD清屏幕
      lcd_display_chinese(1,0,1,0);                //LCD顯示漢字///一
      lcd_display_chinese(1,0,2,1);                //LCD顯示漢字//
      lcd_display_chinese(1,0,3,2);                //LCD顯示漢字//
      lcd_display_chinese(2,0,0,3);                //LCD顯示漢字//
      lcd_display_chinese(2,0,1,4);                //LCD顯示漢字//
      lcd_display_chinese(2,0,2,5);                //LCD顯示漢字//六

      lcd_display_chinese(2,0,3,6);                //LCD顯示漢字//
      lcd_display_chinese(1,1,0,7);                //LCD顯示漢字//八
      lcd_display_chinese(1,1,1,8);                //LCD顯示漢字//
      lcd_display_chinese(1,1,2,9);                //LCD顯示漢字//
      lcd_display_chinese(1,1,3,10);                //LCD顯示漢字//
      lcd_display_chinese(2,1,0,11);                //LCD顯示漢字//

while(1)
{
      delay(10);
}

字庫(kù)程序如下：

顯示期望如下：（“口”為空白）

口一二三四五六口

七八九十壹貳叁肆

實(shí)際顯示如下：

口一二三四五六口

七八口口一口一二

各位大神有沒(méi)有知道為什么的？謝謝！
