CCS/IWR1443BOOST: Trying to get the data for a single object in front of the sensor

Part Number: IWR1443BOOST

Tool/software: Code Composer Studio

I've been working with the IWR1443BOOST and my goal is to get the data of a specific object in front of the sensor. First, I went through the sdk demo to try to isolate the variables for each detected object, which I did successfully. However, I can't manage to get the sensor to give reliable data for the object I want in front of it. I've tried going into the config file and changing the CFAR threshold, but that didn't really help. I just want the sensor to identify the position of my hand in front of it.

The next thing I tried was to use the high accuracy demo to target a specific object. However, the demo would not build and I got a plethora of errors as shown below:

Because of these errors, I decided to try and port the code over to the SDK demo and get the data from there. I managed to get the code over and build with no errors. I then edited the config file to accommodate for the range boundary configuration. I finally ran this code and got a runtime error that I don't know how to fix. The error is below:

If I could get a solution to any of these three approaches that would be great. All I need is to get the data from a single object and it's definitely not as simple as I thought it would be.

Thank you,

Daniel

    Hi Daniel,

    The High Accuracy Demo uses SDK 1.2 and is only compatible with ES2.0 silicon. Do you know if you are using ES2.0 or ES3.0?

    I'm using ES3.0 so I figured that was the issue there. In another forum post about this you said that the solution was to port over the code which is what I attempted to do but got the errors in the second image I posted. Do you know how to fix this error?

    The other approach I had was what I talked about at first and that was isolating the data for the one object I want from the sdk demo. After repeated attempts, I can't figure out how to properly eliminate all the background noise and get the data I want. How would you recommend I do this?

    Hi Daniel,

    Unfortunately it is difficult to know why you are seeing these errors because I haven't seen your code, if you post what is at line 2251 I may be able to provide some insight but it will be difficult for us to provide a full code walk-through at this time.

    Best approach for your scene is to remove as many reflective objects that are around your subject. This might even mean to test the sensor outdoors as the presence of metal contributes to both reflection and disturbance.

    Cheers,

    The code at line 2251 is simply a debug statement as shown in the attached image.
