4、循环函数intrins

_crol_字符循环左移

_cror_字符循环右移

_irol_整数循环左移

_iror_整数循环右移

_lror_长整数循环左移

_lror_长整数循环右移

_nop_空操作8051 NOP 指令

_testbit_测试并清零位8051 JBC 指令

5、中段代码

interrupt 0 外部中断0

interrupt 1 定时器0中断

interrupt 2 外部中断1

interrupt 3 定时器1中断

interrupt 4 串口中断

interrupt 5 定时器2中断(52里面,51没有)

6、IIC总线

开始信号:

void IICstart()

{

scl=1;

delay();

sda=1;

delay();

sda=0;

delay();

scl=0;

}

结束信号

void IICstop()

{

scl=1;

delay();

sda=0;

delay();

sda=1;

::

delay();

}

应答信号

void IICyingda()

{

uchar j;

scl=1;

delay();

while((sda==1)&&j<250)j++;

//sda=0;

//delay();

scl=0;

delay();

}

写信号(写入一8位数据)

void write_byte(uchar w)

{

uchar i,temp;

temp=w;

for(i=0;i<8;i++)

{

scl=0;

delay();

temp=temp<<1;

sda=CY;

delay();

scl=1;

delay();

}

scl=0;

delay();

sda=0;

delay();

}

读信号(读出一个8位数据)

uchar read_byte(void)

{

uchar i,j,k;

sda=1;

delay();

for(i=0;i<8;i++)

{

scl=1;

delay();

j=sda;

k=(k<<1)|j;

scl=0;

delay();

}

scl=0;

delay();

return k;

}

7、时钟调试键盘扫描

void keyscan()

{

if(k1==0)

{

delay(5);

if(k1==0)

{

while(!k1); //

k1num++;

}

if(k1num==1)

{

TR0=0;

write_zhiling(0x80+0x40+11);

write_zhiling(0x0f);

}

if(k1num==2)

{

TR0=0;

write_zhiling(0x80+0x40+8);

}

if(k1num==3)

{

TR0=0;

write_zhiling(0x80+0x40+5);

}

if(k1num==4)

{

k1num=0;

write_zhiling(0x0c);

TR0=1;//

}

if(k1num!=0)

{

if(k2==0)

{

delay(5);

if(k2==0)

{

while(!k2);

if(k1num==1)

{

miao++;

if(miao==60)

{

miao=0;

fen++;

if(fen==60)

{

fen=0;

write_jingwei(7,fen);

}

write_jingwei(10,miao);

write_jingwei(7,fen);

write_zhiling(0x80+0x40+11);

}

write_jingwei(10,miao);

write_zhiling(0x80+0x40+11);

}

if(k1num==2)

{

fen++;

if(fen==60)

{

fen=0;

shi++;

if(shi==24)

}

{

shi=0;

write_jingwei(4,shi);

}

write_jingwei(7,fen);

write_jingwei(4,shi);

}

}

}

if(k1num!=0)

{

if(k3==0)

{

delay(5);

if(k3==0)

{

write_zhiling(0x80+0x40+8);

}

write_jingwei(7,fen);

write_zhiling(0x80+0x40+8);

}

if(k1num==3)

{

shi++;

if(shi==24)

{

shi=0;

write_jingwei(4,shi);

write_zhiling(0x80+0x40+5);

}

write_jingwei(4,shi);

write_zhiling(0x80+0x40+5);

}

while(!k3);

if(k1num==1)

{

miao--;

if(miao==-1)

{

miao=59;

fen--;

if(fen==-1)

{

fen=59;

write_jingwei(7,fen);

}

write_jingwei(10,miao);

write_jingwei(7,fen);

write_zhiling(0x80+0x40+11);

}

write_jingwei(10,miao);

write_zhiling(0x80+0x40+11);

}

if(k1num==2)

{

fen--;

if(fen==-1)

{

fen=59;

shi--;

if(shi==-1)

{

shi=23;

write_jingwei(4,shi);

}

write_jingwei(7,fen);
