上一篇文章，我们拿MATLAB走了一遍1D处理的流程，这一期我们来看看C代码如何实现的，首先回顾一下void MmwDemo_interChirpProcessing()函数，代码如下：
/*** @b Description* @n* Interchirp processing. It is executed per chirp event, after ADC* buffer is filled with chirp samples.** @retval*Not Applicable.*/void MmwDemo_interChirpProcessing(MmwDemo_DSS_DataPathObj *obj, uint8_t chirpPingPongId){uint32_t antIndx, waitingTime;volatile uint32_t startTime;volatile uint32_t startTime1;MmwDemo_DSS_dataPathContext_t *context = obj->context;waitingTime = 0;startTime = Cycleprofiler_getTimeStamp();/* Kick off DMA to fetch data from ADC buffer for first channel */EDMA_startDmaTransfer(context->edmaHandle[MMW_DATA_PATH_EDMA_INSTANCE],MMW_EDMA_CH_1D_IN_PING);/* 1d fft for first antenna, followed by kicking off the DMA of fft output */for (antInd
