【蓝桥杯单片机组】第七届决赛模拟

------------------------------------------------------------------------------------------------

本程序有BUG，在电压测量模式与时间查询模式下，按键使用不灵敏；在电压测量模式下数码管会闪。

使用的iic协议、ds1302协议在前文中有

0、很多很多的定义

1、主程序

void main(){close_buzz();Timer0Init();init_1302();init_dis();Timer1Init();//1微秒@11.0592MHzvhh = read_eeprom(H_ADDRH);vhm = read_eeprom(M_ADDRH);vhs = read_eeprom(S_ADDRH);vlh = read_eeprom(H_ADDRL);vlm = read_eeprom(M_ADDRL);vls = read_eeprom(S_ADDRL);while(1){display();key = keyscan();if(key != 0){switch(key){case 7: mode = 1; break; //timecase 6: mode = 2; break;//vocase 5: mode = 3; break;//frcase 9: mode = 4; break;//sea}}if(mode == 1){ pro_time();}if(mode == 2){pro_vo();}if(mode == 3){ pro_fr();}if(mode == 4){ pro_sea();}}} 

2、设置时间功能

void pro_time(){dis[2] = 10;dis[5] = 10;get_time();  //每一秒读一次时间dis[0] = cur_time[0]/10; dis[1] = cur_time[0]%10; dis[3] = cur_time[1]/10; dis[4] = cur_time[1]%10;dis[6] = cur_time[2]/10; dis[7] = cur_time[2]%10;display();key = keyscan();if(key != 0){switch(key){case 4:pro_set_time();break;//时钟调整}}}void pro_set_time(){uchar time_mode = 0;while(1){if(time_mode == 0){ if(flag1s == 1){dis[0] = init_time[0]/10;    dis[1] = init_time[0]%10; }else{dis[0] = 11;   dis[1] = 11;}dis[3] = init_time[1]/10; dis[4] = init_time[1]%10; dis[6] = init_time[2]/10; dis[7] = init_time[2]%10;}if(time_mode == 1){ if(flag1s == 1){dis[3] = init_time[1]/10;    dis[4] = init_time[1]%10; }else{dis[3] = 11;   dis[4] = 11;}dis[0] = init_time[0]/10; dis[1] = init_time[0]%10;dis[6] = init_time[2]/10; dis[7] = init_time[2]%10;}if(time_mode == 2){ if(flag1s == 1){dis[6] = init_time[2]/10;    dis[7] = init_time[2]%10; }else{dis[6] = 11;   dis[7] = 11;}dis[0] = init_time[0]/10; dis[1] = init_time[0]%10;dis[3] = init_time[1]/10; dis[4] = init_time[1]%10;}display();key = keyscan();if(key != 0){switch(key){case 4:{if(time_mode == 0){time_mode = 1;}else if(time_mode == 1){time_mode = 2;}else if(time_mode == 2){time_mode = 0;}break;}//选择case 11:{if(time_mode == 0){init_time[0]++;if(init_time[0]>23){init_time[0]=0;}}if(time_mode == 1){init_time[1]++;if(init_time[0]>59){init_time[0]=0;}}if(time_mode == 2){init_time[2]++;if(init_time[0]>59){init_time[0]=0;}}break;//+}case 10:{if(time_mode == 0){init_time[0]--;if(init_time[0]<0){init_time[0]=23;}}if(time_mode == 1){init_time[1]--;if(init_time[0]<0){init_time[0]=59;}}if(time_mode == 2){init_time[2]--;if(init_time[0]<0){init_time[0]=59;}}break;//-}case 7: returnflag = 1; break;default: key = 0; break;}}if(returnflag == 1){returnflag = 0;init_1302();break;}}}

3、测量电压模式

uchar vo111;int temp111;void pro_vo(){dis[0] = 10;dis[1] = 1;dis[2] = 10;dis[3] = 11;display();if(flagss == 1){flagss = 0;init_ad();vo111 = read_ad();temp111 = vo111/255.0*5000;}if(temp111 >= vh){get_time();write_eeprom(H_ADDRH,cur_time[0]);write_eeprom(M_ADDRH,cur_time[1]);write_eeprom(S_ADDRH,cur_time[2]);}if(temp111 <= vl){get_time();write_eeprom(H_ADDRL,cur_time[0]);write_eeprom(M_ADDRL,cur_time[1]);write_eeprom(S_ADDRL,cur_time[2]);}   dis[4] = temp111/1000;dis[5] = temp111%1000/100;dis[6] = temp111%100/10;dis[7] = temp111%10;display();key = keyscan();if(key != 0){switch(key){case 4:pro_set_vo();break;//VO调整}}}void pro_set_vo(){uchar vo_mode = 0;//du vh,vlvh1 = read_eeprom(VH_ADDR1);vh2 = read_eeprom(VH_ADDR2);vl1 = read_eeprom(VL_ADDR1);vl2 = read_eeprom(VL_ADDR2);vh = vh1*256+vh2;vl = vl1*256+vl2;   while(1){if(vo_mode == 0){ if(flag1s == 1){   dis[0] = vh/1000;dis[1] = vh%1000/100;dis[2] = vh%100/10;dis[3] = vh%10;}else{   dis[0] = 11;dis[1] = 11;dis[2] = 11;dis[3] = 11;}   dis[4] = vl/1000;dis[5] = vl%1000/100;dis[6] = vl%100/10;dis[7] = vl%10;}if(vo_mode == 1){ if(flag1s == 1){   dis[4] = vl/1000;dis[5] = vl%1000/100;dis[6] = vl%100/10;dis[7] = vl%10;}else{   dis[4] = 11;dis[5] = 11;dis[6] = 11;dis[7] = 11;}   dis[0] = vh/1000;dis[1] = vh%1000/100;dis[2] = vh%100/10;dis[3] = vh%10;}display();key = keyscan();if(key != 0){switch(key){case 4:{if(vo_mode == 0){vo_mode = 1;}else if(vo_mode == 1){vo_mode = 0;}break;}//选择case 11:{if(vo_mode == 0){vh=vh+500;if(vh>5000){vh=0;}}if(vo_mode == 1){vl=vl+500;if(vl>5000){vl=0;}}break;//+}case 10:{if(vo_mode == 0){vh=vh-500;if(vh<0){vh=5000;}}if(vo_mode == 1){vl=vl-500;if(vl<0){vl=5000;}}break;//-}case 6: returnflag = 1; break;default: key = 0; break;}}if(returnflag == 1){returnflag = 0;write_eeprom(VH_ADDR1,vh/256);write_eeprom(VH_ADDR2,vh%256);write_eeprom(VL_ADDR1,vl/256);write_eeprom(VL_ADDR2,vl%256);break;}}}

4、测量频率模式

uchar ft_mode = 0;//0 fr,1 timevoid pro_fr(){float fr,time;dis[0] = 10;//dis[1] = 2;dis[2] = 10;display();TR0 = 1;//start t1;key = keyscan();if(key != 0){switch(key){case 4:{ if(ft_mode == 0) {ft_mode = 1;} else { if(ft_mode == 1){ft_mode = 0;} }  break;}//time fr调整case 7: mode = 1; break; //timecase 6: mode = 2; break;//vocase 5: mode = 3; break;//frcase 9: mode = 4; break;//sea}}if(ft_mode == 0){dis[1] = 2;//test//frif(flagS == 1){TR0 = 0;flagS = 0;fr =  time1flag*65536+TH0*256+TL0;TH0 = 0;TL0 = 0;time1flag = 0;dis[3]=((int)fr)/10000;   dis[4]=((int)fr)%10000/1000;dis[5]=((int)fr)%1000/100;dis[6]=((int)fr)%100/10;dis[7]=((int)fr)%10;}}if(ft_mode == 1){dis[1] = 3;//test//TIMEif(flagS == 1){TR0 = 0;flagS = 0;fr =  time1flag*65536+TH0*256+TL0;TH0 = 0;TL0 = 0;time1flag = 0;time = 1.0/fr * 1000000.0;dis[3]=((int)time)/10000;   dis[4]=((int)time)%10000/1000;dis[5]=((int)time)%1000/100;dis[6]=((int)time)%100/10;dis[7]=((int)time)%10;}}}

5、查询模式

uchar sea_mode = 0;//0 fr,1 timevoid pro_sea(){TR0 = 0;display();key = keyscan();if(key != 0){switch(key){case 4:{if(sea_mode == 0){sea_mode = 1;}else {if(sea_mode == 1){sea_mode = 2;}else {if(sea_mode == 2){sea_mode = 3;}else {if(sea_mode == 3){sea_mode = 0;}}}}break;}//time fr调整case 7: mode = 1; break; //timecase 6: mode = 2; break;//vocase 5: mode = 3; break;//frcase 9: mode = 4; break;//sea}}if(sea_mode == 0){//VLdis[0] = 11;dis[1] = 11;dis[2] = 11;dis[3] = 11;dis[4] = 11;dis[5] = 11;dis[6] = 0;dis[7] = 0;}if(sea_mode == 1){//VLdis[0] = vlh/10;dis[1] = vlh%10;dis[2] = 10;dis[3] = vlm/10;dis[4] = vlm%10;dis[5] = 10;dis[6] = vls/10;dis[7] = vls%10;}if(sea_mode == 2){dis[0] = 11;dis[1] = 11;dis[2] = 11;dis[3] = 11;dis[4] = 11;dis[5] = 11;dis[6] = 0;dis[7] = 1;}if(sea_mode == 3){dis[0] = vhh/10;dis[1] = vhh%10;dis[2] = 10;dis[3] = vhm/10;dis[4] = vhm%10;dis[5] = 10;dis[6] = vhs/10;dis[7] = vhs%10;}}

6、配置程序及中断

void Timer1Init(void)//20毫秒@11.0592MHz{AUXR &= 0xBF;//定时器时钟12T模式TMOD &= 0x0F;//设置定时器模式TMOD |= 0x10;//设置定时器模式TL1 = 0x00;//设置定时初值TH1 = 0xB8;//设置定时初值TF1 = 0;//清除TF1标志TR1 = 1;//定时器1开始计时ET1 = 1;EA = 1;}void Timer0Init(void){AUXR &= 0x7F;//定时器时钟12T模式TMOD &= 0xf0;TMOD |= 0x05;//方式一，count模式TL0 = 0x00;//设置定时初值TH0 = 0x00;//设置定时初值TF0 = 0;//清除TF1标志TR0 = 0;ET0 = 1;}void t1_isr() interrupt 3{TL1 = 0x00;//设置定时初值TH1 = 0xB8;//设置定时初值isrcount++;if(isrcount >= 25){flagss = 1;}if(isrcount >= 50){isrcount = 0;flagS = 1;if(flag1s == 1){flag1s = 0;}else{flag1s = 1;}}}void t0_isr() interrupt 1{TL0 = 0x00;//设置定时初值TH0 = 0x00;//设置定时初值time1flag++;}
