119.c

一个用keil写的,动行在c8051f410上的软件vf的驱动程序,在protes下仿真过.希望对初学者能有用.

#include <c8051f410.H>

#define uchar unsigned char
#define uint  unsigned int 
  uint v5;
void main(void) 
{ XBR1=0X41;
  PCA0MD=0X00;
  OSCICN|=0x04;
  PCA0CPM0=0x46;
  PCA0MD|=0x08;
  for(;;)
  {


  P0MDIN=0x0f;//配置p0为模拟输入
  ADC0MX=7;//选择p0.7为a输入
  AD0LJST=0;//数据右对齐
  AD0EN=1;//使能ad
  AD0BUSY=1;
  REF0CN=3;
  while(AD0BUSY==1);
  v5=(ADC0H*256+ADC0L)/16;
  PCA0CPH0=v5;//1m/x
  if((v5>220)|(v5<10)){CR=0;}
  else {CR=1;};
    
    while(1);  
  }
 }
