RTCC时间不变

我在PIC18F47 J53上有一个RTCC，时间似乎没有改变。我的编译器是XC8V 1.41.My配置位如下：γ-PrimaMaungTrimg RTCOSc= T1OsCurFi也尝试了IntoClinux设置一个定时器中断来检查我的外部晶体振荡器和中断被调用。这与因特克里夫导致时钟不工作相结合导致我相信外部晶体振荡器不是问题的根源。这是我的代码来测试外部振荡器。有人能确认T1确实是使用外部晶体振荡器吗？最后，这里是测试RTCC的代码。注意：最近更新了我的代码。注意到我的RTCWRIEN落后了。时间在流逝，但还没有增加。



      以下为原文

    I have an RTCC on a PIC18F47J53 and the time does not appear to be changing. My compiler   is XC8  v 1.41.

My config bits are set as follows.

#pragma config RTCOSC = T1OSCREF

I also tried INTOSCREF

I setup a timer interrupt to check my external crystal oscillator  and the interrupt is being called.  That combined with the INTOSCREF causing the clock not to work leads me to believe that the external crystal oscillator is not the source of the problem.

Here is my code to test the external oscillator.   Can someone please confirm that T1 is indeed using the external crystal oscillator here?
  INTCONbits.GIE = 1;
  INTCONbits.PEIE = 1;
  
  T1CONbits.T1OSCEN = 1;
  T1CONbits.TMR1CS = 2;
  T1CONbits.TMR1ON = 1;
   
     
  PIR1bits.TMR1IF = 0; // Clear Timer 1 interrupt flag
  PIE1bits.TMR1IE = 1; // Enable Time 1 interrupt
   


Finally here is the code to test the RTCC.

Note: Updated my code recently.  noticed my RTCWREN was backward.   Time is setting but still not incrementing.

    PIE3bits.RTCCIE = 1; //RTCC Interrupt enabled
