标题: 新人求助，51单片机控制LCD12864显示学号
刚入门。
要求是利用单片机控制LCD12864滚动显示学号，名字。程序的显示方法已经写好了，就是不知道主程序里面该怎么写，初始位置怎么定
以下是程序：
#include<reg52.h>
#define uchar unsigned char
#define uint  unsigned int

sbit p_rst=P2^5;
sbit p_csl=P2^4;
sbit p_csr=P2^3;
sbit p_di=P2^2;
sbit p_rw=P2^1;
sbit p_e=P2^0;

uchar code xingming[]=
{
0x20,0x82,0x20,0x82,0x2A,0x45,0x2A,0x45,0xAA,0x25,0x6A,0x15,0x3E,0x0D,0x2B,0xFF,

void disp_Hz(uchar xx,uchar yy,uchar n,uchar fb)//xx为该行第xx个字，共8字，yy为第几行，共8行。

   }

}

  void main()

lcd_init();

while(1) //就是不知道这里改怎么写，试着写过，但是显示的位置有问题
{
   for(t=0;t<64;t++)

}
}

由于初学，知道实际问题应该比较简单，，但是······，希望大神帮忙写一下最后的部分，最好给点注释。非常非常感谢
