ARM-RTC的简单使用

简单RTC应用，获取RTC时间，以及设置时间

void RTC_Ctrl_Set(U8 enable)  //bit位使能
{
if (FALSE == enable)
{
RTCCON &= ~(1 << 0);
}
else
{
RTCCON |= (1 << 0);
}
}

void Get_RTC_Time(RTC_Time_Typedef *time)
{//获取RTC时钟的各个部分
time->second = BCDSEC;
time->minute = BCDMIN;
time->hour = BCDHOUR;
time->date = BCDDATE;  //星期
time->day = BCDDAY;
time->month = BCDMON;
time->year = BCDYEAR;
}

void Set_RTC_Time(RTC_Time_Typedef time)
{//设置RTC时间
RTC_Ctrl_Set(TRUE);

BCDSEC = time.second;
BCDMIN = time.minute;
BCDHOUR = time.hour;
BCDDATE = time.date;  //ÐÇÆÚ
BCDDAY = time.day;
BCDMON = time.month;
BCDYEAR = time.year;

RTC_Ctrl_Set(FALSE);
}
