inandout.h

前两天一个朋友要我写一个51例程

#ifndef __INANDOUT_H__
#define __INANDOUT_H__

#include <reg52.h>
#include <cpudef.h>
void	GPIO_OUT_Config();
void	RelayOut(unsigned	char	Number,bit	OnOff);
void	ButtonDataConfig();
void	SetAdjLight();
uchar	GetButton();
#define		Sel_InputChip_One()		{CS2=1;CS1=1;CS0=0;}
#define		Sel_InputChip_Two()		{CS0=1;CS2=1;CS1=0;}
#define		Sel_InputChip_Three()	{CS0=1;CS1=1;CS2=0;}
#define		Disable_InputChip()		{CS0=1;CS1=1;CS2=1;}

#endif
