PIC24FJ128GA202 RTCC中断不触发

我用MPLABX和MCC设置了PIC，并设置了如图所示的RTCC…RTCC运行，我可以显示在我的LCD下面的代码…可能会在那里，但愚蠢的论坛不会让我添加它见附件。TXT文件显示了在RTCC ISR代码中递增的半个SyxCube变量，除了它从不从零移动。很多人似乎对RTCC中断有问题。我想知道的是，当RTCC在第二个点时，我可以让LCD闪烁一个被设置的数字。有什么想法吗？



      以下为原文

    I set up the PIC using MPLABX and MCC and set the RTCC as shown in picture...  The RTCC runs and I can display on my LCD with following code... would have been there BUT STUPID FORUM WON'T LET ME ADD IT SEE ATTACHED .TXT FILE

Note the half_Sec_count variable that's incremented in the RTCC ISR code except that it never moves from zero.
void __attribute__ ( ( interrupt, no_auto_psv ) ) _ISR _RTCCInterrupt( void )
{
    /* TODO : Add interrupt handling code */
    half_Sec_count++;
   
    // TM I think this is only called when an alARM is triggered but
    // I think I've set the alarm to trigger every half second
    IFS3bits.RTCIF = false;
}
A lot of people seem to have issues with the RTCC interrupt.  What I want to do is know when the RTCC is at the half-second point so I can make the LCD blink a number that is being set.

Any ideas?
