AWRL6432: How to use 'adcDataSource'(Test Mode) with custom ADC raw data file

Part Number: AWRL6432
Other Parts Discussed in Thread: IWRL6432

Hello,

I am working on 'motion_and_presence_detection' demo with sdk version MMWAVE_L_SDK_05_03_00_02.

I want to use the Test Mode provided by the SDK to input previously acquired ADC Raw Data into the iwrl6432 EVM for simulation of radar signal processing and application logic.

I have some questions regarding Test Mode as below.

       1. Quick Guide Document or other related materials for using Test Mode

            - I couldn't find any detailed document for using test mode

       2. Gathering Raw ADC Data for Test Mode

            - currently, I am using iwrl6432evm + DCA1000 +mmwave studio for ADC data gathering.

            - is it possible to use bin file generated from mmwave studio for Test Mode 

Thanks,

Best Regards

Yechan

    Hey Yechan,

    Thanks for reaching out regarding your questions on the Motion and Presence Detection Demo. Regarding test mode documentation, there isn't anything else documented, but we can provide some additional details captured below.

    The test mode is used to inject pre-captured ADC raw data into the buffer instead of filling directly from the front-end. The general workflow for how this works is:

    1. Capture ADC data as a .bin file using the DCA1000
    2. Prepare this data according to the ADC buffer format (with the right Rx-Tx chirp sequence, etc.)
    3. Run the target code with this data by passing its file location in the adcDataSource CLI command to generate processed data

    The generated ADC file from mmWave Studio should work fine for test mode. mmWave Studio should capture data in real mode (2-byte per sample). This is no I-Q shuffling so the data can be used directly. I would recommend following the DCA1000 mmWave Studio User Guide in the Radar Toolbox if you haven't reviewed it before.

    Regards,

    Kristien

    Hello Kristien,

    Thank you for your quick reply.

    I have a question regarding the second step that you've mentioned, which is '2. Prepare this data according to the ADC buffer format (with the right Rx-Tx chirp sequence, etc.)'.

    Do you mean that I have to do some post processing for the adc data captured using dca1000 + mmwave studio?

    I used same cfg for both ADC data capturing and demo application. 

    Regards,

    Yechan

    Hey Yechan,

    Sorry for the confusion. You should be able to use ADC data .bin file captured directly from mmWave Studio because the MPD demo uses the real mode ADC buffer format. There should be no additional processing necessary.
