請問我陷再要寫一個電壓保護的程式
條件為原本有2組PWM輸出，現在要加上當輸入電壓高於1.8V時，PWM不要輸出，要如何撰寫？ 以下是保護程式的設定 在PWM INITIALIZATION下設定 /*---PWM1 INITIALIZATION---*/ IOCON1bits.FLTDAT=0; FCLCON1bits.FLTSRC=1; FCLCON1bits.FLTPOL=1; FCLCON1bits.FLTMOD=1; /*---PWM2 INITIALIZATION---*/ IOCON2bits.FLTDAT=0; FCLCON2bits.FLTSRC=1; FCLCON2bits.FLTPOL=1; FCLCON2bits.FLTMOD=1; /*---CMP1A Configuration---*/ CMPCON1bits.INSEL=0; CMPCON1bits.EXTREF=0; CMPCON1bits.RANGE=1; CMPDAC1bits.CMREF=931; CMPCON1bits.CMPON=1; CMPCON1bits.CMPPOL=1; /*---CMP2A Configuration---*/ CMPCON2bits.INSEL=0; CMPCON2bits.EXTREF=0; CMPCON2bits.RANGE=1; CMPDAC2bits.CMREF=931; CMPCON2bits.CMPON=1; CMPCON2bits.CMPPOL=1; /*---CMP3A Configuration---*/ CMPCON3bits.INSEL=0; CMPCON3bits.EXTREF=0; CMPCON3bits.RANGE=1; CMPDAC3bits.CMREF=931; CMPCON3bits.CMPON=1; CMPCON3bits.CMPPOL=1; 將上面的設定好之後就算沒有高於1.8v時也不會有PWM輸出 是哪裡有問題呢?
