CCS/AWR1642: CAPTURE

Hello Wei Liu,

A1:  For TDM MOMO, you will need to configure 2 chirps that have the same profile. You seem to have configured the chirps right. Why do you think this is wrong?

A2: Below is the snapshot for interleaved and non-interleaved data format 

non-interleaved

Interleaved 

Let me know if this clears your doubt.

Thanks,

Raghu

in ti/drivers/test/mem_capture:

For Q1:
I have tried this way to configure and perform data collection, but I have an error, as follows:

and these are my code：

static void MemCapture_initLinkChirpCfgParams (rlChirpCfg_t* ptrChirpCfg)

{

   /* Initialize the chirp configuration: */

   memset ((void *)ptrChirpCfg, 0, sizeof(rlChirpCfg_t));

   /* Populate the chirp configuration: */

   ptrChirpCfg->chirpStartIdx   = 0U;

   ptrChirpCfg->chirpEndIdx     = 0U;

   ptrChirpCfg->profileId       = 0U;

   ptrChirpCfg->startFreqVar   = (uint32_t)(0U * (1U << 26) / 3.6e9);

   ptrChirpCfg->freqSlopeVar   = (uint16_t)(0U * (1U << 26) / (3.6e6 * 900.0));

 ptrChirpCfg->idleTimeVar     = (uint32_t)(0U * 1000 / 10);

   ptrChirpCfg->adcStartTimeVar = (uint32_t)(0U * 1000 / 10);

ptrChirpCfg->txEnable       = 1U;

   ptrChirpCfg->chirpStartIdx   = 1U;

   ptrChirpCfg->chirpEndIdx     = 1U;

   ptrChirpCfg->profileId       = 0U;

   ptrChirpCfg->startFreqVar   = (uint32_t)(0U * (1U << 26) / 3.6e9);

   ptrChirpCfg->freqSlopeVar   = (uint16_t)(0U * (1U << 26) / (3.6e6 * 900.0));

   ptrChirpCfg->idleTimeVar     = (uint32_t)(0U * 1000 / 10);

   ptrChirpCfg->adcStartTimeVar = (uint32_t)(0U * 1000 / 10);

   ptrChirpCfg->txEnable       = 2U;

}

static void MemCapture_initLinkFrameParams (rlFrameCfg_t* ptrFrameCfg)

{

   /* Populate the frame configuration: */

   ptrFrameCfg->chirpStartIdx     = 0U;

   ptrFrameCfg->chirpEndIdx       = 1U;

   ptrFrameCfg->numLoops           = 128;//

   ptrFrameCfg->numFrames         = 1;

   ptrFrameCfg->framePeriodicity   = (uint32_t)(100 * 1000000 / 5);

   ptrFrameCfg->triggerSelect     = 1U;

   ptrFrameCfg->frameTriggerDelay = (uint32_t)(0 * 1000000 / 5);

}

static void MemCapture_initMMWaveOpenParams (MMWave_OpenCfg* ptrOpenCfg)

{

   /* Initialize the open configuration: */

   memset ((void*)ptrOpenCfg, 0, sizeof(MMWave_OpenCfg));

   /* Populate the open configuration: */

   ptrOpenCfg->freqLimitLow                       = 760U;

   ptrOpenCfg->freqLimitHigh                       = 810U;

   ptrOpenCfg->chCfg.rxChannelEn                   = 0xFU;//Enable RX Channel 0,1,2,3

   ptrOpenCfg->chCfg.txChannelEn                   = 0x3U;//Enable TX Channel 0,1

   ptrOpenCfg->chCfg.cascading                     = 0U;

   ptrOpenCfg->lowPowerMode.lpAdcMode             = 1U;

   ptrOpenCfg->adcOutCfg.fmt.b2AdcBits             = 2U;//16bit

   ptrOpenCfg->adcOutCfg.fmt.b2AdcOutFmt           = 2U;//Complex with Image band

   ptrOpenCfg->disableFrameStartAsyncEvent         = false;

   ptrOpenCfg->disableFrameStopAsyncEvent         = false;

}

So I want to know if I have to modify other parts of the code?

For Q2:

You didn't understand my problem. I have read the message about non-interleaved fomat from 'xWR1xxx ADC Raw Data Capture' .So i have known the message that you post me.(You send the message which is about tx1,rx1)

Now i want to use ti/drivers/test/mem_capture in tx2,rx4 mode. I want to know if i get the data from L3 , what format is it stored in?

In addition, I want to know if the tx1,rx4 mode is used in mem_capture, is it stored in the same format as the non-interlaced mode you mentioned?

Thanks
