【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

4、测量频率模式

uchar ft_mode = 0;		//0 fr,1 time
void pro_fr()
{

	float fr,time;

	dis[0] = 10;
//	dis[1] = 2;
	dis[2] = 10;

	display();
	TR0 = 1;		//start t1;
	key = keyscan();
	if(key != 0)
	{

				 {ft_mode = 1;}
				 else
				 {
				 	if(ft_mode == 1){ft_mode = 0;}
				 } 
				 break;
			
			}//time fr调整
			case 7: mode = 1; break; 	//time
			case 6: mode = 2; break;	//vo

			case 9: mode = 4; break;	//sea
		}
	}
	if(ft_mode == 0)
	{

		//fr
		if(flagS == 1)
		{
			TR0 = 0;
			flagS = 0;
			fr =  time1flag*65536+TH0*256+TL0;

		}

	}
	if(ft_mode == 1)
	{

		//TIME
		if(flagS == 1)
		{

5、查询模式

uchar sea_mode = 0;		//0 fr,1 time
void pro_sea()
{
	TR0 = 0;


	display();
	key = keyscan();
	if(key != 0)
	{

			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; 	//time
			case 6: mode = 2; break;	//vo
			case 5: mode = 3; break;	//fr
			case 9: mode = 4; break;	//sea
		}
	}
	if(sea_mode == 0)
	{

		dis[0] = 11;
		dis[1] = 11;
		dis[2] = 11;
		dis[3] = 11;
		dis[4] = 11;
		dis[5] = 11;

	}
	if(sea_mode == 1)
	{
		//VL
		dis[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;

	}
	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;

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

	ET1 = 1;
	EA = 1;

}

void Timer0Init(void)

}


void t1_isr() interrupt 3

	isrcount++;
	if(isrcount >= 25)
	{

	}
	if(isrcount >= 50)
	{

	}	
}
void t0_isr() interrupt 1

	time1flag++;
	
}
