用C語言編寫單片機程序

#include

sbit

csb_SAT=

P1^0;

//定義超聲波發生腳

void

delay(void)

//延時25微秒,12T晶元用12M誤差

0us

{

unsigned

char

a;

for(a=11;a0;a–);

}

void

csb_fs(int

dat)

{while(dat–){csb_SAT=1;delay();csb_SAT=0;delay();}}

//發射

void

main()

{

EA=1;

while(1)

{

csb_fs(10);

delay();delay();delay();delay();delay();delay();delay();delay();delay();

IE=0x83;

//INT0允許中斷

while(IE);

P1_1=1;delay();P1_1=0;delay();P1_1=1;delay();P1_1=0;delay();P1_1=1;delay();P1_1=0;delay();

}

}

void

int0_chuankou(void)

//外部INT0中斷子程序

{

IE=0;//禁止INT0中斷

}

單片機 c語言編寫

單片機C語言編寫與普通電腦C語言類似，只不過硬體成分更多些。比如：

#includereg51.h

#define uchar unsigned char

uchar code ledtab[]={0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f};//0-9

unsigned char sec=0,min=0,hour=12,scanled;

unsigned char key,time;

unsigned char disdat[6];

sbit K=P1^0;

void dischg()

{

disdat[0]=sec%10;

disdat[1]=sec/10;

disdat[2]=min%10;

disdat[3]=min/10;

disdat[4]=hour%10;

disdat[5]=hour/10;

}

void t0isr() interrupt 1 //秒計時

{

TR0=0;

TH0=0x3c;

TL0=0xb0;

TR0=1;

time++;

if(time==20)

{

time=0;

sec++;

if(sec59)

{

sec=0;

min++;

if(min59)

{

min=0;

hour++;

if(hour23)hour=0;

}

}

}

dischg();

}

void t1isr() interrupt 3 //顯示

{

TH1=0xec;

TL1=0x78;

switch(scanled)

{

case 0:

P2=0x01;

P0=~ledtab[disdat[5]];

break;

case 1:

P2=0x02;

P0=~ledtab[disdat[4]];

break;

case 2:

P2=0x04;

P0=~ledtab[disdat[3]];

break;

case 3:

P2=0x08;

P0=~ledtab[disdat[2]];

break;

case 4:

P2=0x10;

P0=~ledtab[disdat[1]];

break;

case 5:

P2=0x20;

P0=~ledtab[disdat[0]];

break;

default:break;

}

scanled++;

scanled%=6;

}

main()

{

TMOD=0x11;

TH0=0x3c;

TL0=0xb0;

TH1=0xec;

TL1=0x78;

EA=1;

TR1=1;

ET0=1;

ET1=1;

sec=50;

min=59;

hour=23;

scanled=0;

time=0;

key=0;

dischg();

while(1)

{

if(K==0)

{

while(K==0);

key++;

key%=2;

}

switch(key)

{

case 0:

TR0=1;

break;

case 1:

TR0=0;

break;

}

}

}
