本人用单片机51和adc0808采集电压.不知道什么状况ADC不能工作。程序如下；#include
#define uchar unsigned char
#define uint unsigned int
#define N 100
#define x 1
#define y 0
uint qian,shi,bai,ge;
uint temp;
uchar code table[]={0xc0,0xf9,0xa4,0xb0,0x99,0x92,0x82,0xf8,0x80};
sbit P20=P2^0;
sbit P21=P2^1;
sbit P22=P2^2;
sbit P23=P2^3;
sbit P27=P2^7;
sbit P36=P3^6;
sbit P37=P3^7;
void delay()
{
uint i;
for(i=0;i[此贴子已经被作者于2009-5-29 10:01:42编辑过]
