标题: 无字库LCD12864显示8个汉字后面不显示，为什么？
本帖最后由 hk0506 于 2018-7-6 08:35 编辑

在无字库LCD12864上面写字的时候，写了八个字后，后面的不显示了，然后一步一步调，发现超过8个就不显示了。
显示程序如下：
void lcd_display_chinese(uchar screen,uchar page,uchar col,uint mun)
{             //screen:选择屏幕参数，page:选择页参数0-3，col:选择列参数0-3，mun:显示第几个汉字的参数
      int a;
      mun=mun*32;
      select_screen(screen);                                  //选屏
      W_CMD(0xb8+(page*2));                                  //页：一页8点行
      W_CMD(0x40+(col*16));                                  //列：一列1点列
      for (a=0;a<16;a++)
      {
            W_DATA(chinese[mun++]);                         //一个字16x16

      }
      W_CMD(0xb8+(page*2)+1);                                  //两页一行
      W_CMD(0x40+(col*16));                                  //行列指针自加1
      for (       a=0;a<16;a++)
      {
            W_DATA(chinese[mun++]);

      }
}

主函数如下：
void main()
{
      initLCD();                                                 //LCD初始化
      clear_screen(0);                                           //LCD清屏幕
      lcd_display_chinese(1,0,1,0);                //LCD显示汉字///一
      lcd_display_chinese(1,0,2,1);                //LCD显示汉字//
      lcd_display_chinese(1,0,3,2);                //LCD显示汉字//
      lcd_display_chinese(2,0,0,3);                //LCD显示汉字//
      lcd_display_chinese(2,0,1,4);                //LCD显示汉字//
      lcd_display_chinese(2,0,2,5);                //LCD显示汉字//六

      lcd_display_chinese(2,0,3,6);                //LCD显示汉字//
      lcd_display_chinese(1,1,0,7);                //LCD显示汉字//八
      lcd_display_chinese(1,1,1,8);                //LCD显示汉字//
      lcd_display_chinese(1,1,2,9);                //LCD显示汉字//
      lcd_display_chinese(1,1,3,10);                //LCD显示汉字//
      lcd_display_chinese(2,1,0,11);                //LCD显示汉字//

while(1)
{
      delay(10);
}

字库程序如下：
uchar code chinese[]={

都说了无字库，自己不会添加一下吗

就是字库的问题？

字库的问题，自己重新添加一下

你取模的字体有出错，定义位置也不对
