滚动的起始地址（37h）设置了没有，33h只是设置滚动的区域而已

设置了，不知道对不对，我贴出来。
//进入垂直滚动模式
void Enter_Vertical_Scroll_Mode(void)
{
   *CmdAddress=0x0033; //设置滚动区域
   *DataAddress=0x0001;
   *DataAddress=0x00e0;
   *DataAddress=0x0001;
   *DataAddress=0x00e0;
   *DataAddress=0x0001;

   disphanzi(100,100,"红");
   dispstring(200,200,"陈长兵Ok!");
   //*CmdAddress=0x0037; //设置滚动起始
   //*DataAddress=0x0000;
   //*DataAddress=0x0000;
}
//连续滚动
void Continuous_Scroll(void)
{

   *CmdAddress=0x0037; //设置滚动起始
   *DataAddress=0x0000;
   *DataAddress=Scroll_Cnt;
   Scroll_Cnt++;

}
主程序：

   }
