標題: 大佬幫忙看看c程序哪里少了點什么 感謝萬分
1.實驗目的
掌握SPI總線的ADC0832模數(shù)轉換的使用方法。
2.實驗內容
利用ADC0832采集直流0~5V的電壓，并在LCD1602上顯示結果。
C語程序
#include <reg52.H>
#include"LCD1602.h"
#include"ADC0832.h"
#define uchar unsigned char
#define uint unsigned int
uchar Voltage = 0;
/*主函數(shù)*/
void main()
{
LCD1602_init();
LCD1602_string(1,1," ADC0832 Test");
LCD1602_string(2,1," Voltsge: V");
while(1)
{
Voltage = adc0832(1);
Display_2num_dot(2,10,Voltage*50/255);
}
}
#include<reg52.h>
#include<intrins.h>
#define uchar unsigned char
#define unit unsigned int
sbit ADCS =P1^5;
sbit ADDI =P3^2;
sbit ADDO =P1^7;
sbit ADCLK=P1^6;
uchar adc0832(uchar channel)
{
uchar i=0;
uchar dat=0;
if(channel==0)channel=2;
if(channel==1)channel=3;
ADDI=0;ADCS=1;ADCLK=0;
ADDI=1;ADCS=0;ADCLK=1;
ADCLK=0;ADCLK=1;
ADDI=channel&0x1;
ADCLK=0;ADCLK=1;
ADDI=(channel>>1)&0x1;
ADCLK=0;ADDI=1;
dat=0;
for(i=0;i<8;i++)
{
dat|=ADDO;
ADCLK=1;
ADCLK=0;
dat<<=1;
if(i==7)dat|=ADDO;
}
ADCS=1;ADCLK=0;ADDO=1;
return(dat);
}
#ifndef __ADC0832_H__
#define __ADC0832_H__
unsigned char adc0832(unsigned char channel);
#endif

#include<reg52.h> #include<intrins.h> #define uchar unsigned char #define unit unsigned int sbit ADCS =P1^5; sbit ADDI =P3^2; sbit ADDO =P1^7; sbit ADCLK=P1^6;應該放在主函數(shù)前面吧

還有沒有什么錯呢，大哥。謝謝
