Part Number: AWR1642

I used RADAR studio and TSW1400 to capture ADC raw data. the data is saved off to C:\ti\mmwave_dfp_00_07_00_04\rf_eval\radarstudio\PostProc\adc_data.bin. What is the format of the .bin file? I used 1 TX 4 RX and 16bit ADC.  thanks!  -Xinsi Lin

  • Hello Xinsi,

    Please check AWR1xxx Data Path Programmer’s Guide  for details about packaged data over LVDS lane.

    Section  4.1.4.2 Format Mapping in that documents talks about AWR1642 data mapped to LVDS lanes.

    Thank you,

    Hello Xinsi Lin,
    The bin file saved from HSDC pro would have the data in sequential order . If you are using 16 bit complex the order of data would be (for N samples per chirp):
    RX1-I sample 0 , RX1 Q sample 0 , RX1 Isample1 , RX1 Qsample1 .....Rx1 I sampleN-1 , RX1 Q sample N-1

    After 1 chirp data the second chirp data follows.

    Hello, Xinsi lin
    What should i do to capture ADC raw data from AWR1642 by using MMWAVE-DEVPACK and TSW1400?
    I have read RadarStudio_User's_Guide , but I still have no idea to do it.
    Would you give me some information and idea.
    Thank you!

    Hello Xiamen,
    You can refer to the following training material : training.ti.com/mmwave-sensor-raw-data-capture-using-tsw1400-board

    Hello Vivek Dham,

    Following your advise, I refer to training.ti.com/mmwave-sensor-raw-data-capture-using-tsw1400-board. In Radar Studio(v1.7.4.0), mmwave-sensor-raw-data-capture-using-tsw1400-board suggest me to select the Application/User UART, Buad rate 115200.

    But when I select Buad rate 115200, I can't connect SPI. The "SPI connect" button was stuck.

    Then I refer to Radar_Studio_User's_Guide,  it suggest me to set the Buad rate to 921600. 


    When I set the Buad rate to 921600, I can connect SPI successfully.

    I'm confused. Because when I do the mmw demo and capture demo, the Buad rate of the Application/User UART is set to 115200.

    Why do I connect the SPI successfully in the Radar Studio until I set the Application/User UART to 921600?

    Thank you!

  • In reply to Zhicheng Hu:

    Hello Zhicheng,
    The UART rate depends on the rate set by the application. The mmw demo application sets a 115200 baud rate while the radar studio application sets it to 921600 kbps.
