AWR1843AOP: Out of box demo I can't get coordinate and velocity information.

Part Number: AWR1843AOP

Hello there

I ran the out of box demo with AWR1843AOP. I used 3.6.0.0-LTS sdk latest version. I sent the "profile_2d_aop" and "profile_3d_aop" cfg files located in the C:\ti\mmwave_sdk_03_06_00_00-LTS\packages\ti\demo\xwr18xx\mmw\profiles extension from UART and ran the demo.
After running the demo, I saw that there was a data flow in the graphics on the interface and it changed.

my first question
When I debug the out box demo with ccs, I saw that only the y value changed from the (x, y, z and velocity ) information that should come for each detected point. I saw no change in x,z and velocity values. x,z and velocity values ​​were equal to 0. what is the reason of this. What should I do to be able to read x, z and velocity values?

my second question
I tried to change the angle values ​​from the parameter "aoaFovCfg -1 -90 90 -90 90" in the cfg file. but the scanned angle did not change even though I changed the angle information. tested in different combinations but I couldn't see any change. (I have used different parameter values ​​"aoaFovCfg -1 -10 90 -90 90" ,"aoaFovCfg -1 -10 40 -10 40" ,"aoaFovCfg -1 -10 10 -10 10"

my own opinion, I think that I can't get 3D data information. but I only get y-axis information. It's not even 2 sizes, I don't understand how this happens. I will be glad if you help.

  • Hi,

    Before you try to debug the demo with CCS, please just run the flashed demo.

    You can place the sensor in a certain location and move in front of it. You should see the movement in the display.

    Also, you can also use a highly reflective object and move it in front of the radar.

    If you don't have one, you can use some aluminum foil.

    Let's make sure this works for you before you further evaluate the demo

    thank you
