PQA怎样检测采样通道掉电

在core0.c中开一个定时器每10周期对比一次捕获的频率是否一致，通常频率是在跳动的，如果检测到频率不跳动了，说明采样通道没有上电；

代码如下：

if( bPwrDwnDetTimeOut )//for power down detect{if(CaptureZeroPointPeriod_Backup != CaptureZeroPointPeriod){CaptureZeroPointPeriod_Backup = CaptureZeroPointPeriod;}else{    memset(AdcData, 0, (uint32_t )sizeof(AdcData)); //Clear the AdcData memory    memset(&FreqAC, 0, (uint32_t )sizeof(FreqAC));  //Clear the FreqAC memoryTriggerCore1ByGpio();}bPwrDwnDetTimeOut = false;}
