基于aduc845的ad0809控制程序

#include <stdio.h>
#include <ADuC845.h>
#include "absacc.h"
#define AD_IN0 XBYTE[0x0FEFF] 
sbit EOC=P3^3;
unsigned char a;

 void delay(int length)
{
while (length >=0)
    length--;
}


void main(void)
{  	
  T3CON =0x83;      		//9600 Baud rate
  T3FD = 0x12;
  SCON = 0x52;
  //printf("%bx\n", a); 
  while(1)
  {	  
  printf("%bx\n", a);
	AD_IN0=0;		 //启动转换
	while(EOC==0); //等待AD转换结束
	a=AD_IN0;         //读AD转换结果




  // 	printf("%bx\n", a); 

  

   }
