用仿真是可以实现的，可是一弄到开发板上就无法实现，数字都显示不出来，只有个别会亮
程序和图，求修改
#include <STC12C5A60S2.H>
#include <intrins.h>
#define uchar unsigned char
#define uint unsigned int
sbit wela1=P3^0;
sbit wela2=P3^1;
sbit wela3=P3^6;
sbit wela4=P3^7;
uchar code table[]={
0xc0,0xf9,0xa4,0xb0,
0x99,0x92,0x82,0xf8,
0x80,0x90};
uint shu,qi,sh,ba,g;
void delay2(uint z)
{
uint t1,y;
for(t1=z;t1>0;t1--)
for(y=110;y>0;y--);
}
void main()
{
wela1=0;
P2=table[1];
wela1=1;
delay2(1);
P2=0xFF;
wela1=0;
wela2=0;
P2=table[2];
wela2=1;
delay2(1);
P2=0xFF;
wela2=0;
wela3=0;

P2=0xFF;

wela4=0;
P2=table[4];
wela4=1;
delay2(1);
P2=0xFF;

}
