河南理工大學電子設計綜合訓練報告作息時間控制器姓名：李曉宇付道義學號：310708020814310708020810專業班級：自動化07-8指導老師：譚興國所在學院：電氣工程與自動化學院2010年7月2日摘要本設計是作息時間控制器，由單片機最小系統、按鍵模塊、數碼管顯示模塊、鬧鐘模塊組成。采用單片機AT89S52與12MHZ晶振相連；通過按鍵KI、K2、K3、K4控制時間的校正、鬧鐘時間設定；數碼管顯示模塊用來顯示時間，顯示格式為“時分”，并能夠根據需要顯示年、月、日，由數碼管小數點閃動作為秒計數；鬧鐘模塊進行到時提醒并作出相應動作：發光二極管閃亮，同時播放音樂。本設計中，利用單片機定時器設計時間計時處理，采用單片機內部的T0定時器溢出中斷來實現，工作在T1方式下，定時50微妙，則連續中斷20次即為一秒，得到了我們所需時間的最小單位秒，60秒為一分，60分為一小時，24小時為一天，1、3、5、7、8、10、12月為31天，4、6、9、11月為30天，閏年二月為29天，非閏年二月為28天，12個月為一年。采用這種時間設計思想來進行時間設置。在整個系統的設計中，單片機的P0口輸出顯示信號，P1口按鍵輸入控制、P2口用來掃描，為動態顯示、P3口鬧鐘模塊。該設計用C51編寫程序，由于匯編語言的移植性比較差，而C語言則比較靈活。許多子函數都可以直接移植過去。作息時間控制器作息時間控制器#0x93,0xF0,//00233HZ,1#0x73,0xF1,//00247HZ,20x49,0xF2,//00262HZ,2#0x07,0xF3,//00277HZ,30xC8,0xF3,//00294HZ,40x73,0xF4,//00311HZ,4#0x1E,0xF5,//00330HZ,50xB6,0xF5,//00349HZ,5#0x4C,0xF6,//00370HZ,60xD7,0xF6,//00392HZ,6#0x5A,0xF7,//00415HZ,70xD8,0xF7,//00440HZ1//12TOC\o"1-5"\h\z0x4D,0xF8,//00466HZ1#//130xBD,0xF8,//00494HZ2//140x24,0xF9,//00523HZ2#//150x87,0xF9,//00554HZ3//160xE4,0xF9,//00587HZ4//170x3D,0xFA,//00622HZ4#//180x90,0xFA,//00659HZ5//190xDE,0xFA,//00698HZ5#//200x29,0xFB,//00740HZ6//210x6F,0xFB,//00784HZ6#//220xB1,0xFB,//00831HZ7//230xEF,0xFB,//00880HZ'10x2A,0xFC,//00932HZ'1#0x62,0xFC,//00988HZ'20x95,0xFC,//01046HZ'2#0xC7,0xFC,//01109HZ'30xF6,0xFC,//01175HZ'40x22,0xFD,//01244HZ'4#0x4B,0xFD,//01318HZ'50x73,0xFD,//01397HZ'5#0x98,0xFD,//01480HZ'60xBB,0xFD,//01568HZ'6#0xDC,0xFD,//01661HZ'7//35};//音樂符號串解釋函數changedata(uchar*song,uchar*diao,uchar*jie){uchari,i1,j;chargaodi;ucharbanyin;、ucharyinchang;//Oo3Qucharcodejie7[8]={0,12,14,16,17,19,21,23};*diao=*song;for(i=0,i1=0;;){gaodi=0;banyin=0;yinchang=4;if((*(song+i)=='|')||(*(song+i)==''))i++;switch(*(song+i)){case',':gaodi=-12;i++;break;case'、'：gaodi=12;i++;break;}if(*(song+i)==0){*(diao+i1)=0;*(jie+i1)=0;return;}j=*(song+i)-0x30;i++;j=jie7[j]+gaodi;yinc：switch(*(song+i)){case'#'：i++;j++;gotoyinc;case'-'：yinchang+=4;i++;gotoyinc;case'_'：yinchang/=2;i++;gotoyinc;case'.':yinchang=yinchang+yinchang/2;i++;gotoyinc;}*(diao+i1)=j;*(jie+i1)=yinchang;i1++;}}////奏樂函數voidplay(uchar*songdata){uchari,c,j=0;uintn;uchardiaodata[40];ucharjiedata[40];changedata(songdata,diaodata,jiedata);TR1=1;for(i=0;diaodata[i]!=0;i++){tl0_f=freq[diaodata[i]*2];th0_f=freq[diaodata[i]*2+1];for(c=0;c<jiedata[i];c++){for(n=0;n<24;n++){scankey();if(y==0){TR1=0;return;}display();}}TR1=0;for(n=0;n<500;n++);TR1=1;}TR1=0;}voidtime0(void)interrupt1{TH0=0x3c;TL0=0xb0;cnt++;if(y==1&&(set_h==h&&set_m==m))sd=~sd;elsesd=1;if(cnt==20){sec++;cnt=0;if(sec==60){sec=0;m++;if(m==60){m=0;h++;if(h==24){h=0;day++;switch(month){case1:if(day==32){month++;day=1;}break;case2:if(year%4==0){if(day==30){month++;day=1;}}else{if(day==29){month++;day=1;}}break;case3:if(day==32){month++;day=1;}break;case4:if(day==31){month++;day=1;}break;case5:if(day==32){month++;day=1;}break;case6:if(day==31){month++;day=1;}break;case7:if(day==32){month++;day=1;}break;case8:if(day==32){month++;day=1;}break;case9:if(day==31){month++;day=1;}break;case10:if(day==32){month++;day=1;}break;case11:if(day==31){month++;day=1;}break;case12:if(day==32){month++;day=1;}break;}if(month==13){month=1;year++;}}}}if(x==0)bianhuan1();}}timer1()interrupt3{TL1=tl0_f;TH1=th0_f;//調入預定值BEEP=~BEEP;//取反音樂輸出IO}voidmain(void){init();while(1){display();scankey();if(y==1&&(set_h==h&&set_m==m))play(mamahao);elseBEEP=0;}}voidinit(void){BEEP=0;TMOD=0x11;TH0=0x3c;TL0=0xb0;ET0=1;TR0=1;ET1=1;TR1=0;EA=1;}voiddisplay(void){P2=0xfe;P0=a[qian];if(x%2==1&&cnt>=10)P0&=0x00;delay(20);P2=0xfd;P0=a[bai];if(x%2==1&&cnt>=10)P0&=0x00;elseif(x==0&&cnt>=10)P0|=0x80;delay(20);P2=0xfb;P0=a[shi];if(((x%2==0&&x!=0)||x==7)&&cnt>=10)P0&=0x00;delay(20);P2=0xf7;P0=a[ge];if(((x%2==0&&x!=0)||x==7)&&cnt>=10)P0&=0x00;delay(20);}voidm_choose(void){switch(month){case1:if(day==32)day=1;elseif(day==0)day=31;break;case2:if(year%4==0){if(day==30)day=1;elseif(day==0)day=29;}else{if(day==29)day=1;elseif(day==0)day=28;}break;case3:if(day==32)day=1;elseif(day==0)day=31;break;case4:if(day==31)day=1;elseif(day==0)day=30;break;case5:if(day==32)day=1;elseif(day==0)day=31;break;case6:if(day==31)day=1;elseif(day==0)day=30;break;case7:if(day==32)day=1;elseif(day==0)day=31;break;case8:if(day==32)day=1;elseif(day==0)day=31;break;case9:if(day==31)day=1;elseif(day==0)day=30;break;case10:if(day==32)day=1;elseif(day==0)day=31;break;case11:if(day==31)day=1;elseif(day==0)day=30;break;case12:if(day==32)day=1;elseif(day==0)day=31;break;}voidset_time(void){qian=set_h/10;bai=set_h%10;shi=set_m/10;ge=set_m%10;}voidset_day(void){qian=month/10;bai=month%10;shi=day/10;ge=day%10;}voidbianhuan(void){qian=year/1000;bai=year%1000/100;shi=year%100/10;ge=year%10;}voidbianhuan1(void){qian=h/10;bai=h%10;shi=m/10;ge=m%10;}voidscankey(void){if(K1==0){delay(20);if(K1==0){while(K1==0);x++;if(x==3)set_time();elseif(x==5)set_day();elseif(x==7)bianhuan();elseif(x==8){x=0;bianhuan1();}}}if(K2==0){delay(20);if(K2==0){while(K2==0);switch(x){case0:break;case1:h++;if(h==24)h=0;bianhuan1();break;case2:m++;if(m==60)m=0;bianhuan1();break;case3:set_h++;if(set_h==24)set
