帮你修改好了，编译通过，程序核心内容没有修改，，对比一下你自己的，看看有什么不一样的地方，代码如下：

#include<reg51.h>
#define ROWP P2
#define COLP P1
#define orange P3
void deply1ms(unsigned char);

unsigned char disp[][8]=
{{0x00,0x1c,0x22,0x41,0x41,0x22,0x1c,0x00},
{0x00,0x40,0x44,0x7e,0x7f,0x40,0x40,0x00},
{0x00,0x00,0x66,0x51,0x49,0x36,0x00,0x00},
{0x00,0x00,0x22,0x41,0x49,0x36,0x00,0x00},
{0x00,0x10,0x1c,0x13,0x7c,0x7c,0x10,0x00},
{0x00,0x00,0x27,0x45,0x45,0x45,0x39,0x00},

{0x00,0x00,0x26,0x49,0x49,0x3e,0x00,0x00}};
unsigned char speed=30;

void delay1ms(unsigned char x)
{ int i,j;
for(i=0;i<x;i++)
for(j=0;j<120;j++);}

main()
