基于stc15f2k60s2芯片单片机编程（数码管）

                 **蓝桥杯stc15f2k60s2芯片编程（数码管）**

**

**

（1）数码管显示01234567

**

**

#include <stc15f2k60s2.h>

unsigned char shuzu[]={0XC0,0XF9,0XA4,0XB0,0X99,0X92,0X82,0XF8,0X80,0X90,0XBF,0XFF};
unsigned char i,j;

void main()
{

P2=0XA0;P0=0X00;P2=0X80;P0=0XFF;
 
	while(1){
		
			i++;
	if(i==8)i=0;
	
		P0=0XFF;
 P2=(P2&0X1F)|0XE0;	 
 P2&=0X1F; 

// P0=1<<i; 
 P2=(P2&0X1F)|0XC0;	
  P0=1<<i;
		P2=P2&0X1F;

// P0=shuzu[i];
 P2=(P2&0X1F)|0XE0;	 
 P0=shuzu[i];
		P2&=0X1F; 
j=1000;while(j--);

	}

}

**

**

（2）通过中断写数码管

**

**

#include <stc15f2k60s2.h>
#include <intrins.h>
void shumaguan();
void Timer0Init();
void Delay100us();
unsigned char abile[]={0XC0,0XF9,0XA4,0XB0,0X99,0X92,0X82,0XF8,0X80,0X90,0XBF,0XFF};
unsigned char saomiao[]={0XFF,0XFF,0XFF,0XFF,0XFF,0XFF,0XFF,0XFF};

void main()
{
while(1){
	P2=0XC0;P0=0X01;P2=0XFF;P0=0XFF;
	Timer0Init();
	shumaguan();
	Delay100us();
}
}


void shumaguan()
{
  saomiao[0]=abile[0];
  saomiao[1]=abile[5];
	saomiao[2]=abile[2];
	saomiao[3]=abile[1];
	saomiao[4]=abile[1];
	saomiao[5]=abile[3];
	saomiao[6]=abile[1];
	saomiao[7]=abile[4];
}


void weixuan() interrupt 1
{
	unsigned char i;
	 P2=P2&0x1f|0xe0;
	P0=0xff;
	P2=0x1f;
  P2=P2&0x1f|0xc0;
	P0=1<<i;
	P2=0x1f;
  P2=P2&0x1f|0xe0;
	P0=saomiao[i];
	P2=0x1f;
	i++;
	if(i==8) i=0;
}
void Timer0Init()		//[email protected]
{
	AUXR |= 0x80;	
	TMOD &= 0xF0;	
	TL0 = 0xAE;	
	TH0 = 0xFB;		
	TF0 = 0;		
	TR0 = 1;		
	EA=1;
	ET0=1;
}
void Delay100us()		//@11.0592MHz
{
	unsigned char i, j;

	_nop_();
	_nop_();
	i = 2;
	j = 15;
	do
	{
		while (--j);
	} while (--i);
}

**

（3）通过按键控制数码管加1

**

#include <stc15f2k60s2.h>
#include <intrins.h>
unsigned char shuzu[]={0XC0,0XF9,0XA4,0XB0,0X99,0X92,0X82,0XF8,0X80,0X90,0XBF,0XFF};
unsigned char i,j,miao;
sbit K1=P3^0;
void anjian();
void Delay10ms();		//@11.0592MHz
void main()
{

P2=0XC0;P0=0X01;P2=0XFF;P0=0XFF;  //????????,???
 
	while(1){
		anjian();


 P2=(P2&0X1F)|0XC0;	//´ò¿ªÎ»Ñ¡
		P0=0x80;  //0000 0001
 P2&=0X1F; 

 P2=(P2&0X1F)|0XE0;	 //´ò¿ª¶ÎÑ¡
 P0=shuzu[miao%10];
P2&=0X1F;
		j=1000;while(j--);
		
		P2=(P2&0X1F)|0Xc0;	//´ò¿ªÎ»Ñ¡
		P0=0x40;  //0000 0001
 P2&=0X1F; 
		
		P2=(P2&0X1F)|0XE0;
		P0=shuzu[miao/10];
		P2&=0X1F;
		j=1000;while(j--);

	}

}

void anjian()
{
if(K1==0)
{
Delay10ms();
	if(K1==0)
{
miao++;
}
while(!K1);
}

}

void Delay10ms()		//@11.0592MHz
{
	unsigned char i, j;

	i = 108;
	j = 145;
	do
	{
		while (--j);
	} while (--i);
}

（4）通过按键，改变数码管的数值
