基于51单片机的可控硅调压调光程序

基于51单片机的可控硅调压调光程序-带过零检测它的程序，主要是过零检测（INT0）和触发信号（INT1）给可控硅的控制极一个信号怎么写，还有用三个按键控制开关、加、减来控制灯亮暗。C的快回答程序：#includereg52.h#includeintrins.hsbitledRS=P1^0;sbitledRW=P1^1;sbitledE=P1^2;sbitkeyjia=P2^7;sbitkeyjian=P2^6;sbitcontrolLD=P1^3;bitflag1=1;bitflag2=1;unsignedcharcodetable[]=guangliangdu;unsignedcharcodetable1[]=00;intnum,flag=0,count=0;charliangdu=3;voiddelaykt(void)//导通延时{unsignedchara;for(a=2;a0;a--);}voiddelay(intz)//可调延时{unsignedx,y;for(x=z;x0;x--)for(y=110;y0;y--);}voiddelay9ms(void)//误差-0.43402777778us延时9ms{unsignedchara,b,c;for(c=1;c0;c--)for(b=224;b0;b--)for(a=17;a0;a--);}voidwrite_com(unsignedcom)//写指令{ledRS=0;P0=com;delay(10);ledE=1;delay(20);ledE=0;}voidwrite_date(unsigneddate)//写数据{ledRS=1;P0=date;delay(10);ledE=1;delay(20);ledE=0;}voidwrite_liangdu(unsignedliangdu)//写亮度{intshi,ge;shi=(liangdu-3)/10;ge=(liangdu-3)%10;write_com(0x80+0x40+7);write_date(0x30+shi);write_date(0x30+ge);}voidinit()//初始化{controlLD=1;//触发控制初始化ledRW=0;//液晶初始化ledE=0;write_com(0x38);write_com(0x0c);write_com(0x06);write_com(0x80);for(num=0;num15;num++){write_date(table[num]);delaykt();}write_com(0x80+0x40);for(num=0;num15;num++){write_date(table1[num]);delaykt();}EA=1;//外部中断设置EX0=1;IT0=1;}voidkeyscanf()//键盘判断{if(keyjia==0)//加键判断{delaykt();if(keyjia==0){if(flag1==1){flag1=0;liangdu++;if(liangdu==10)liangdu=3;write_com(0x80+0x40+7);write_liangdu(liangdu);}}}elseif(keyjia!=0){delaykt();if(keyjia!=0)flag1=1;}if(keyjian==0)//减键判断{delaykt();if(keyjian==0){if(flag2==1){flag2=0;liangdu--;if(liangdu==2)liangdu=9;write_com(0x80+0x40+7);write_liangdu(liangdu);}}}elseif(keyjian!=0){delaykt();if(keyjian!=0)flag2=1;}}voidzhongduan()interrupt0//外部中断{flag=1;}voidtimepd()//同步标志判断与定时器设置{if(flag==1){flag=0;TMOD=0x01;TH0=(65536-1000*(10-liangdu))/256;TL0=(65536-1000*(10-liangdu))%256;ET0=1;TR0=1;}}voidtime0()interrupt1//定时中断程序{count=1;}voidchufa()//MOS3020触发{if(count==1){count=0;controlLD=0;delaykt();controlLD=1;delay9ms();controlLD=0;delaykt();controlLD=1;}}voidmain(){init();while(1){keyscanf();timepd();chufa();}}
