上面code的部份中,Init_CMP中,IEC1bits.AC1IE = 1才對,
在編輯的時候打錯,抱歉!

而實際程式也是寫上1,編輯的時候不知道怎麼改成0了。

板主與各路高手好:

下面測試程式中,希望CMP1A輸入高於1.25V即進入中斷,
然後跳出sleep模式
想請各位看看以下的程式是否哪裡出錯

int main( void )
{
ADPCFG = 0xfff0;
TRISBbits.TRISB7 = 0;
LATBbits.LATB7 = 0; // 測試用
Init_CMP1();
while(1)
{
Sleep()
}
}

void Init_CMP1(void)
{
IPC7bits.AC1IP = 7;
IEC1bits.AC1IE = 0; // 啟動比較器#1中斷致能

CMPCON1bits.INSEL = 0; //選取CMP1A
CMPCON1bits.EXTREF = 0; //內部Ref
CMPCON1bits.RANGE = 1; //AVDD/2
CMPCON1bits.CMPPOL= 0; //non inverted
CMPDAC1 = 0x01FF; //Ref=AVDD/4=1.25V;
CMPCON1bits.CMPON = 1; /* CMP1 enabled */
}

void _ISR _CMP1Interrupt(void)
{
LATBbits.LATB7 = 1; // 測試已進入中斷
IEC1bits.AC1IE = 0; // 則將比較器中斷致能關閉

IFS1bits.AC1IF = 0;
}


結果LATB7都沒亮,代表都沒進入中斷。然而系統耗電流很低,的確有進入Sleep mode。希望知道問題出在哪邊,謝謝各位!!
