c51单片机贪吃蛇8x8点阵

c51单片机贪吃蛇8x8点阵的实现需要以下几个步骤：

1.初始化：设置行线和列线的IO口方向，初始化蛇的位置和方向，初始化食物的位置。

2.扫描按键：通过扫描按键来改变蛇的方向。

3.移动蛇：根据蛇的方向移动蛇的位置，同时判断是否吃到了食物，如果吃到了，则增加蛇的长度。

4.更新显示：根据蛇的位置和长度以及食物的位置来更新点阵的显示。

下面是一个简单的c51单片机贪吃蛇8x8点阵的代码示例：

#include <reg52.h>

#define u8 unsigned char
#define u16 unsigned int

sbit SRCLK = P3^6;
sbit RCLKS = P3^5;
sbit SER = P3^4;

u8 Rows[8] = {0xFE, 0xFD, 0xFB, 0xF7, 0xEF, 0xDF, 0xBF, 0x7F}; //行线值
u8 Cols[8] = {0x7F, 0xBF, 0xDF, 0xEF, 0xF7, 0xFB, 0xFD, 0xFE}; //列线值

u8 Snake[50][2]; //蛇的位置
u8 Food[2]; //食物的位置
u8 SnakeLen = 3; //蛇的长度
u8 SnakeDir = 1; //蛇的方向

void Delay(u16 i)
{
    while(i--);
}

void Led(u8 dat,8 dat2) //dat为行线值，dat2为列线值
