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);
