http://www.openedv.com/forum.php?mod=viewthread&tid=283109&extra=论坛有客户问到这个，所以整合了下，在原有显示图片的基础上增加了从片内FLASH读取汉字点阵数据的功能

不过帖子链接中的程序没有标准库，本帖子用了标准库，基于该帖子下的程序移植而来
http://www.openedv.com/forum.php?mod=viewthread&tid=283220

利用PCtoLCD2002生成“开” “发” “板”三个点阵库并存放在片内FLASH，这三个汉字的点阵库数据存放在text.c中
[mw_shl_code=c,true]//24*24的OLED汉字点阵，包括三个汉字：开、发、板。这三个汉字的点阵库，是利用PCtoLCD2002生产的，
//软件设置的取模方式同OLED实验ASCII的取模方式一样，字体采用24*24大小，一个汉字点阵占用72字节。

整个程序最重要的是LCD_Show_Font（）这个函数就是用来支持从片内FLASH读取汉字点阵库并显示在液晶上，在main.c中来调用该函数
[mw_shl_code=c,true]//在指定位置，显示一个24*24大小的汉字
//x,y :汉字的坐标
//index:汉字编号（在字库数组里面的编号）
void LCD_Show_Font(u16 x,u16 y,u8 index)
{
      u8 temp,t,t1;
      u16 y0=y;
      u8 *dzk;
      u8 csize=72;                                     //一个24*24的汉字72字节
      dzk=(u8*)LCD_HZK_TBL[index];       //得到汉字编号对应的点阵库
      for(t=0;t<csize;t++)
      {
            temp=dzk[t];                               //得到点阵数据
            for(t1=0;t1<8;t1++)                      //按照从高位到低位的顺序画点
            {
                     if(temp&0x80)LCD_Fast_DrawPoint(x,y,POINT_COLOR);
                     else LCD_Fast_DrawPoint(x,y,BACK_COLOR);
                     temp<<=1;
                     y++;
                     if((y-y0)==24)                      //对y坐标的处理，当y坐标距起始坐标差24个像素点，x坐标加1
                     {
                              y=y0;
                              x++;
                              break;
                     }
            }
      }
}[/mw_shl_code]
main函数如下
[mw_shl_code=c,true] int main(void)
{
      u8 i=0;
      POINT_COLOR=RED;
      delay_init();          //延时初始化
      NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2);// 设置中断优先级分组2
      LED_Init();                         //初始化与LED连接的硬件接口
      uart_init(115200);
      LCD_Init();
      POINT_COLOR=RED;
      LCD_Show_Font(50,10,0);
      LCD_Show_Font(74,10,1);
      LCD_Show_Font(98,10,2);
      while(1)
      {
            if(i==0)
            {
                     image_display(20,40,(u8*)gImage_image1);//在指定地址显示图片
            }
            i++;
            if(i>10)i=0;
            LED0=!LED0;
            delay_ms(200);
      }
