DCA1000EVM: Does it play only the first 300?

Part Number: DCA1000EVM
Other Parts Discussed in Thread: IWR1443BOOST

Hi,

I use DCA1000EVM and IWR1443BOOST.

When data is collected with the following parameters,
the frame upper limit is 300 on the playback screen.

No of Frame:0
No of Chirp:128
Bin Data 0:1,048,576kb(It got full with about 2 minutes)
Bin Data 1:1,048,576kb
Bin Data 2: 188,928kb(Stop in the middle)
Post Prock Frame:300(Data 0,1,and 2)
Post Prock Chirp:128

Does it play only the first 300?
Or is it thinning out the data to 300 frames?

Regards,

    Hi,

    Thank you for your reply.
    "It's the first 300" means that


    (i) we can collect more than 300 frames of sensor data with 0 of # of frame setting,


    (ii)but mmWave Studio can play only the first 300 frames of the data file.


    Is my understanding correct?  I just want to confirm.

    Hi,

    I checked mmwave_studio_user_guide.pdf

    P26:

    4. If the number of frames (in the frame config) is zero,
    then the number of frames that will be captured is 300.
    This will take a long time, so it is recommended that you provide a
    finite number of frames in the frame config

    I tried with two kinds of settings.

    In Frame 0, the first data is 1,048,576 kb
    In Frame 300, only one data file can be created and its size is 50,400 kb
    In the playback screen both frames are 300

    From the above it is possible to capture 300 or more data,
    Only 300 frames are displayed
    Is it a good idea?

    Hi,

    If the number of frame is 0, the RAW file will be saved with each file of 1GB. The post-processing of mmwave studio only handles the first RAW file and the first 300 frames. But the saved raw data could be more than 300 frames. Customer can process using Matlab.
    As for the packetreorder and zero packing, I suggest to run the .exe file on each RAW binary to generate adc data file for process. You can run that command in windows command window. I tried the following command on my PC under the PostProc folder
    C:\ti\mmwave_studio_01_00_00_00\mmWaveStudio\PostProc>Packet_Reorder_Zerofill.exe adc_data_Raw_0.bin adc_data_1.bin test.log
    I can see adc_data_1.bin is generated.

    Thanks and Regards,
    Michelle
