问 答 1: 希望能对你有用#include <reg52.h>
#include <stdio.h>
#include <intrins.h>
#define uchar unsigned char
#define ulong unsigned long
#define uint  unsigned int
extern delay(uchar d_time);
sbit cl_1543 = P1^2;
sbit di_1543 = P1^3;
sbit do_1543 = P1^4;
sbit cs_1543 = P1^5;

uint ad_1543(uchar port){        //括号里面的参数为地址参数

uint data ad_date;uchar data i,ad_temp;
ad_date = 0;
cl_1543=0;
delay(5);
cs_1543=0;
do_1543 = 1;      
port<<=4;
ad_date = 0;
for (i=0;i<4;i++) //把通道号打入1543
{
    if(port&0x80){di_1543 = 1;}
    else{di_1543 = 0;}
    cl_1543=1;
    delay(5);
    cl_1543=0;
    port<<=1;
    ad_date <<=1;
    if (do_1543) ad_date |= 0x0001;
    else ad_date &= 0xfffe;
}
    
for (i=0;i<6;i++)         
{
    ad_date <<=1;
    if (do_1543) ad_date |= 0x0001;
    else ad_date &= 0xfffe;
    cl_1543=1;
    delay(5);
    cl_1543=0;
}

}

 答 2: 谢谢，我明天就试试
