RTC_GetTime 读出来的时间都是0 怎么回事？

指针变量需要指向实际变量的地址,否则请传入真实的变量地址:

你可以这样:

        //PUINT16 year,month,day,hour,m,sec;
        uint16_t year,month,day,hour,m,sec;
        RTC_GetTime(&year,&month,&day,&hour,&m,&sec);
        PRINT("========%04d-%02d-%02d %02d:%02d:%02d=========\r\n",year,month,day,hour,m,sec);

或者这样:

        uint16_t year1,month1,day1,hour1,m1,sec1;
        PUINT16 year,month,day,hour,m,sec;
        year = &year1;
        month = &month1;
        day = &day1;
        hour = &hour1;
        m = &m1;
        sec = &sec1;
        //uint16_t year,month,day,hour,m,sec;
        RTC_GetTime(year,month,day,hour,m,sec);
        PRINT("========%04d-%02d-%02d %02d:%02d:%02d=========\r\n",*year,*month,*day,*hour,*m,*sec);
