单片机控制四位数码管左边两个自加右边两个熄灭该怎么修改程序这个程序好像只能从个位开始加不知道该怎么定位到百位开始逐渐自加
#include
#define uchar unsigned char
#define uint unsigned int

uchar code Led[]={0xc0,0xf9,0xa4,0xb0,0x99,0x92,0x82,0xf8,0x80,0x90};
uchar code hang[]={0x01,0x02,0x00,0x00};

uint count;
uint oldCount;

void delay()
{ unsigned chari; for(i=0;i=50) {
i=0;
if(count>=19)count=0;
count++;
}
