Original question:

MMWCAS-RF-EVM: Harvest and Parse Capture Data Periodically

AWR1243: Format of the data received from the DSP board.

Part Number: AWR1243
Other Parts Discussed in Thread: MMWCAS-RF-EVM, MMWCAS-DSP-EVM,

Hello,

We are working on cascaded model of mmwave radar MMWCAS-RF-EVM (AWR1243) with MMWCAS-DSP-EVM. 

I'm aware that AWR1243 is just radar front-end and the processing is done in the DSP board. We are planning to use ROS/python to get the data from the DSP board use it for sensor fusion and for live streaming. So we need to know what is the output and the format of the output that is received through the ethernet. 

I did refer to a similar thread https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/898978/mmwcas-rf-evm-harvest-and-parse-capture-data-periodically/3323734#3323734 . The reply doesn’t help in figuring out the question asked. 

As of what I’ve explored, the user cases applicable for the cascaded mmwave radar is section 3.9.1.6 in ProcessorSDKRadar_UserGuide. Is there anything else other than that that I’m missing out on? There are a lot of use cases in the TI resource explorer. But all are for AWR14x, AWR16x, etc. I believe the remaining processing other than the radar front end (AWR12x) is done by the DSP board. What is the data that is received through the ethernet from the DSP board? Is it the same data as that in AWR14x? Can the TI resources example be used in anyway for our cascaded application?

Please guide us with this.

Regards,

Aparna

    Hi,

    I assume you are interested in the data format for the cascade TDA based real time demo.

    Unfortunately the team that developed this demo is no longer available for support

    There is a matlab gui that you can take a look at:

    C:\PROCESSOR_SDK_VISION_03_08_00_00\vision_sdk\apps\src\rtos\radar\src\usecases\cascade_radar_object_detect\radar_cascade_demo.m

    This should provide you some insight on the data format received by the gui

    thank you
