MMWCAS-DSP-EVM: What is the output data structure?

Hello Jairo, 

Please refer to the below linked FAQ page for this : 

https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/925288/faq-mmwcas-rf-evm-cascade-board-related-queries (#6) 

Hope this helps. Let us know if you need further assistance.

Hi Ishita Kochar,

I have read the posts of the link but I think is not what we are looking for, the posts are questions about how to work with the raw data of the sensor, we want the processed data (range, speed, angle, etc), I found this .m script where mentions the tlvs but inside that folder there is no documentation about the tlv format, we need that documentation and also the name of the .c file which generates the packet in the tlv format and send it over ethernet to matlab to know what is the format of the processed data

file: radar_cascade_demo.m

source: C:\PROCESSOR_SDK_RADAR_03_08_00_00\vision_sdk\apps\src\rtos\radar\src\usecases\cascade_radar_object_detect

this is a piece of the  radar_cascade_demo.m code where mentions the TLVs :

 % get the packet header
        [msgHeader, byteVecIdx, frameNum] = getBufferHeader(dataArray, frameNum);

        if  msgHeader.totalLength == 0
            continue;
        end
        Params.gui.cloudPointsPresent = 0;
        Params.gui.rangeProfilePresent = 0;
        Params.gui.azimHeatMapPresent = 0;
        Params.gui.rangeDopplerHeatMapPresent = 0;
        pointCloud.numObj = 0;

        for tlvIdx = 1: msgHeader.numTLVs
            [tlv, byteVecIdx] = getNextTLV(dataArray, byteVecIdx);
             switch tlv.type
                case OP_SECTION_DATATYPE_SYSTEM_INFO
                    [systemInfo, byteVecIdx] = getSystemInfo(dataArray,...
                                               byteVecIdx);
                    if systemInfo.numDopplerBins ~= Params.numDopplerBins
                        fprintf('ERROR: Unexpected Doppler FFT size!\n');
                        return;
                        EXIT_KEY_PRESSED = 1;
