有谁知道 PieVectTable.ADCINT=&ad 是什么意思 谢谢了！

在这个程序中
EALLOW; // This is needed to write to EALLOW protected registers
PieVectTable.ADCINT=&ad;
EDIS; // This is needed to disable write to EALLOW protected registers

InitAdc();

// Enable INT14 which is connected to CPU-Timer 2:
IER |= M_INT1;
//KickDog();
// Enable global Interrupts and higher priority real-time debug events:

EINT; // Enable Global interrupt INTM
ERTM; // Enable Global realtime interrupt DBGM
while(AdcRegs.ADC_ST_FLAG.bit.SEQ1_BSY==0)
{

AdcRegs.ADCTRL2.bit.SOC_SEQ1=1;

}

for(;

{
KickDog();
}
}

interrupt void ad(void)
{
IFR=0x0000;
// PieCtrl.PIEIFR1.all = 0;
PieCtrl.PIEACK.all=0xffff;
a2++;
a1[0]=((float)AdcRegs.RESULT0)*3.0/65520.0+adclo;
a1[1]=((float)AdcRegs.RESULT1)*3.0/65520.0+adclo;

a1[10]=((float)AdcRegs.RESULT10)*3.0/65520.0+adclo;
a1[11]=((float)AdcRegs.RESULT11)*3.0/65520.0+adclo;
a1[12]=((float)AdcRegs.RESULT12)*3.0/65520.0+adclo;

EINT;

}

有谁知道 PieVectTable.ADCINT=&ad 是什么意思 谢谢了!!

将中断服务子程序ad 的地址和中断向量表里的adc中断关联起来

再问问 这个中断是怎么执行的 谢谢

你好中断程序的设置应该有问题 a1[0]=((float)AdcRegs.RESULT0)*3.0/4095.0+adclo;
