AWR1642: About CW Mode Setting

Part Number: AWR1642
Other Parts Discussed in Thread: MMWAVE-SDK

Hi SIr 

we refer to below link 

https://e2e.ti.com/support/sensor/mmwave_sensors/f/1023/t/643124?AWR1642BOOST-Problems-using-continuous-mode-on-AWR1642-using-dfeDataOutputMode-2

The continuous mode is not supported in the mmW demo application. This is the reason you are seeing the assert in the DSP code.

The continuous mode is supported only in the Capture demo application in the MMWAVE-SDK.

In the latest SDK , we didn't see demo capture demo application. 

C:\ti\mmwave_sdk_02_00_00_04\packages\ti\demo\xwr16xx

Do you know TI move the capture demo app to where ?  or it is the same app in below link

C:\ti\mmwave_sdk_02_00_00_04\packages\ti\drivers\test\mem_capture

please advise

    Hi,

    Starting in SDK 1.2 and later the capture demo is no longer supported.

    C:\ti\mmwave_sdk_02_00_00_04\packages\ti\drivers\test\mem_capture is not the capture demo.

    There are several options to use Continuous mode

    1) Enable Continuous Mode in the mmWave SDK 2.x demo. Demo code would have to be modified
    2) Use mmWave Studio - this would require a Devpack Board

    Thank you

    Hi Sir

    We used mmWave demo and execute below command

    sensorStop
    flushCfg
    dfeDataOutputMode 2
    channelCfg 15 1 0
    adcCfg 2 1
    adcbufCfg -1 0 0 1 0
    guiMonitor -1 0 0 0 0 0 0
    lowPower 0 1
    contModeCfg 77 0 0 6000 0 0 30 1 512
    sensorStart

    we got “DSS Exception: ../dss_main.ć, line 1742.”.
    MmwDemo_dssAssert(frameTotalChirps <= 32);

    The exception is number of frame chirp <= 32.

    And the framecfg parameter can not be used in “dfeDataOutputMode 2”.
    We would get “Error: Configuration is valid only if the DFE Output Mode is Chirp”

    please advise

    Hi,
    This is expected, the mmWave SDK demo does not support dfeDataOutputMode 2. Please see the mmWave SDK user's guide, page 14

    Thank you

    Have you considered using mmWave Studio and the DCA1000 capture card to capture raw data for CW mode?

    Thank you
