本人想做一个16X16的点阵游戏机，在网上看到有人做了，但是程序有些不明白，求大神帮忙。
下面是程序
#include"reg51.h"
#include"stdlib.h"
#include"intrins.h"
#include"keyscan.h"
#define uchar unsigned char
#define uint unsigned int
sbit SDI=P3^4; //串行数据输入
sbit SCK=P3^6; //移位
sbit RCK=P3^5; //并行输出
extern uchar startcontrol;
uchar h; //底部下落的高度,y=0,刚刚出现
uchar shape_num; //一共19种形状，=0~18
uint speed; //下落速度
uint initial_speed; //下落的初始速度
uint system_speed; //系统下落速度，会随着分数的增加而减小，下落速度会加快
uint fast_speed; //按下down键时，方块的下落速度
uint rand_num; //随机数变量，产生随机方块
uint k;
uint score; //游戏分数
uchar code num_hang[]={ 0x00,0x01,0x00,0x02,0x00,0x04,0x00,0x08,0x00,0x10,0x00,0x20,0x00,0x40,0x00,0x80,

我想知道那个staticdata数组是什么意思，求相助。
