核心代码

变量定义

struct rtc_time set_time;
//设置时间变量
uint32_t temp_num = 0;
uint8_t day_max=0 ;
int flag=0;
char string[50];

int flage=1 ;
extern __IO uint32_t TimeDisplay ;
extern __IO uint32_t TimeAlarm ;
uint32_t clock_timestamp;
uint32_t current_timestamp;
//定义年月
int year,mon,mday,hour,min,sec;

处理年月日时间数据

根据不同的按键进行一个传入的数据判断以及输入

//选择日期
static void Change(int i){
	if(flage==1||flage==2){
		sprintf((char*)string,"%d%d",year,i);
		year=atoi(string);
		if(year>999){
			flage=3;
		}
	}else if(flage==3){
		sprintf((char*)string,"%d%d",mon,i);
		mon=atoi(string);
		if(string[0]==string[1]){
			sprintf((char*)string,"%d",i);
			mon=atoi(string);
			flage=4;
		}else if(mon>9){
			flage=4;
		}
	}
	else if(flage==4){
		sprintf((char*)string,"%d%d",mday,i);
		mday=atoi(string);
		if(string[0]==string[1]){
			sprintf((char*)string,"%d",i);
			mday=atoi(string);
			flage=5;
		}else if(mday>9){
			flage=5;
		}
	}
	else if(flage==5){
		sprintf((char*)string,"%d%d",hour,i);
		hour=atoi(string);
		if(string[0]==string[1]){
			sprintf((char*)string,"%d",i);
			hour=atoi(string);
			flage=6;
		}else if(hour>9){
			flage=6;
		}
	}
	else if(flage==6){
		sprintf((char*)string,"%d%d",min,i);
		min=atoi(string);
		if(string[0]==string[1]){
			sprintf((char*)string,"%d",i);
			min=atoi(string);
			flage=7;
		}else if(min>9){
			flage=7;
		}
	}
	else if(flage==7){
		sprintf((char*)string,"%d%d",sec,i);
		sec=atoi(string);
		if(string[0]==string[1]){
			sprintf((char*)string,"%d",i);
			sec=atoi(string);
			flage=8;
		}else if(sec>9){
			flage=8;
		}
	}

	
	 printf("%d %d %d %d %d %d n",year,mon,mday,hour,min,sec);
}
