    There is a code in SRR demo about when the code is detected it takes that object and put in to some buffer to process that data ahead and send it on the uart pin.

    In the given code of Short Range Radar there is DSS and MSS. My application is when the target get detected from more than 50m i have to switch on the light. I want to modify that given demo code at certain place when the target is detected and I can send signal from code so that i can switch on the light automatically. For that I have to find that code at a particular place this code is available in given DSS or MSS of demo code. I am asking for that particular place at which i can add my code and modify as per my application .I am asking for that particular place at which this code is available in DSS or MSS.

    Hello Arpit,

    The SRR demo does not make use of the MSS project. Please closely review the reference design for the implementation details of the SRR demo. The reference code is also provided and can be examined in CCS. As highlighted in section 2.3.4 Data Path of the reference design. The object processing occurs in the data_path.c file. There are many ways to implement what you are interested in if you examine the data_path.c file you can see that one point to intercept the target list in the populateOutputs function around lines 4362 which traverses the detected object list.

        /* 1. Detected Object List */
    for (ik = 0; ik < obj->numDetObj; ik ++)
    {
        detObjFinal[ik].speed   = detObj2D[ik].speed;
        detObjFinal[ik].peakVal = detObj2D[ik].peakVal;
        detObjFinal[ik].x       = detObj2D[ik].x;
        detObjFinal[ik].y       = detObj2D[ik].y;
    }
