本来想做一个基于stc15单片机0-20v自动换量程电压表的，程序写好了在keil5里能正常编译。一仿真就出感叹号，Proteus卡死。
程序如下：
#include <stc15f2k60s2.h>
#include <intrins.h>
#define uchar unsigned char
#define uint unsigned int
uchar code71[]={0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f};
uchar code72[]={0xbf,0x86,0xdb,0xcf,0xe6,0xed,0xfd,0x87,0xff,0xef};
uchar wei[4]={0xfe,0xfd,0xfb,0xf7};//weixuan
unsigned char flag;
int f=0;
uint l=0;
void delay(uint ms)
{
uint i,j;
for(i=ms;i>0;i--)
for(j=110;j>0;j--);
}
void initial()
{

P0=0x00;
}
void AD()
{
int f=0;
uchar status;

delay(100);
