IWRL6432: ADC Data Capture Tool

Yuichi Morita
Intellectual 345 points
Part Number: IWRL6432

Tool/software:

I can get ADC data from ADC Data Capture Tool as bin file.

C:\ti\radar_toolbox_3_00_00_05\radar_toolbox_3_00_00_05\tools\Adc_Data_Capture_Tool_DCA1000_CLI

I want to analyze the bin file.

Can I use below matlab script to process the bin file gutted by ADC Data Capture tool？

C:\ti\mmwave_studio_04_01_00_06\mmWaveStudio\Scripts\MatlabExamples\matlabParsingScript

When I use this matlab script, Do I have to change setting in accordance with TDM or BPM？

Regards,

Yuichi

    Hi, Yuichi:

    Yes, you can use this script.   You will need to modify the following parameters manually

    n_rx_chan = 3; % 3 RX channels
    n_tx_chan = 2; % 2 TX channels
    n_samp_per_chirp = 128; % 128 ADC samples per chirp
    n_chirps_per_frame = 64; % 64 chirps per frame = numChirpInBurst*numBurstInFrame/n_tx_chan (assume TDM or BPM is used)
    n_frames = 5; % number of frames to process

    The script does not do BPM demodulation, you will need to add yourself.

    Best,

    Hello,Zigang,

    Thank you for reply.

    You mean that this matlab script can not process bin file for BPM？

    If I want to process bin file for BPM, Do I have to change matlab script？

     

    Do you have any documents that explain format of bin file？

     

    Regards,

    Yuichi

    Hi, Yuichi:

    The same parsing script can still be used. What you get after the parsing script will be 6 channels (two chirps and each chirp has 3 RX channels)

    While in the case of TDM, you have:

    adc_chirp1Rx1= Tx1Rx1 ;

    adc_chirp1Rx2= Tx1Rx2 ;

    adc_chirp1Rx3= Tx1Rx3 ;

    adc_chirp2Rx1= Tx2Rx1 ;

    adc_chirp2Rx2= Tx2Rx2 ;

    adc_chirp2Rx3= Tx2Rx3 ;

    In the case of BPM, you have

    adc_chirp1Rx1= Tx1Rx1 + Tx2Rx1;

    adc_chirp1Rx2= Tx1Rx2 + Tx2Rx2;

    adc_chirp1Rx3= Tx1Rx3 + Tx2Rx3;

    adc_chirp2Rx1= Tx1Rx1 - Tx2Rx1;

    adc_chirp2Rx2= Tx1Rx2 - Tx2Rx2;

    adc_chirp2Rx3= Tx1Rx3 - Tx2Rx3;

    and you will need to apply BPM demodulation at the end of parsing script to get 

    Tx1RX1 = 1/2 * (adc_chirp1Rx1+ adc_chirp2Rx1);

    Tx2RX1 = 1/2 * (adc_chirp1Rx1- adc_chirp2Rx1);

    Hope it makes sense to you.  

    Best,

    Zigang
