IWR1443BOOST: Demo are stpopped without Range Direction and Doppler Direction.

Part Number: IWR1443BOOST

Hi,

If Range Direction and Doppler Direction are not used,
Are Demo stopped?

I use mmWave Demo Visializer,online.

Platform:xWR14xx
SDK:1.2
Antenna Config:4Rx,2Tx(15 deg)

Range Direction : no checked.
Doppler Direction :no checked.


I push "Send Config to mmw Device",demo stated.

The demonstration started smoothly
I confirme the display of many plots.

But, when I move my hands at random in front of the sensor ,
and the sensor falls. The plots all stopped.
the mmWave Demo Visializer was freezed.

Number of detection Objects :100
(When plots were moving,it's under 10 usualy.)
InterFrameProcessingMargin(usec):about 50000 to 55000
(When plots were moving,it's about 80000 to 85000 .)

    Hi,
    Did you modify any parameter/Code in SDK demo? Could you please share the config file you are using for this test?
    You can try to reduce the frame rate to ensure transmit time is enough for these object data, also increase the CFAR threshold to test if it can work when the object become less.
    If you have any further questions, please let me know. Thanks.

    HI,

    Thank you very much.

    I use default bin of SDK 1.2.
    \\mmwave_sdk_01_02_00_05\firmware\radarss
    xwr12xx_xwr14xx_radarss.bin

    \\mmwave_sdk_01_02_00_05\packages\ti\demo\xwr14xx\mmw
    xwr14xx_mmw_demo_mss.bin

    I saved my settings in cfg.
    It was output as follows.

    Hi,

    It's because the number of objects exceeds the limitation 100 when you moving you hand.

    There's 2 methods to solve this issue:

    1. Reduce the number of object(recommended)
      1. Increase the CFAR threshold. cfarCfg 0 2 8 4 3 0 2560
      2. Or enable the PeakGrouping. peakGrouping 1 1 1 1 229
    2. Increase the MMW_MAX_OBJ_OUT limitation in C code.
      1. Change it from 100 to 500 objects. Then the processing chain can work well.
      2. datapath.h line64, #define MMW_MAX_OBJ_OUT 500
      3. detected_obj.h line10 #define MMW_MAX_OBJ_OUT 500

    if you have any further questions, please let me know. Thanks.

    Regards,

    Wesley

    Hi,
    Thank you very much.

    I changed cfarcfg "0 2 8 4 3 0 1280" to "0 2 8 4 3 0 2560",and
    MMW_MAX_OBJ_OUT 100 to 500.
    PeakGrouping still "1 1 1 1 229".

    Movement of mmw Visualizer Demo has stabilized much
    and it rarely stops stopping.
    It did not stop as long as I was watching.
