DCA1000EVM: False return in data DCA1000EVM + AWR1843Boost

DCA1000EVM: Frameconfig function error

Other Parts Discussed in Thread: AWR1843BOOST,

Hi there, 

I am using AWR1843Boost+DCA1000EVM and trying to run the LUA script provided in https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1112328/dca1000evm-false-return-in-data-dca1000evm-awr1843boost/4122568?tisearch=e2e-sitesearch&keymatch=frameconfig#4122568. It returns an error at ar1.FrameConfig(0, 2, 20, 128, 480, 0, 1), but it works well when I change it to ar1.FrameConfig(0, 0, 8, 128, 40, 0, 0, 1) which is from DataCaptureDemo_xWR.lua in /mmWaveStudio/Scripts. I noticed that the difference is the number of inputs( 7 in the first and 8 in the second), so I would like to ask what the inputs are.  And is there a manual that explains these ar1 series functions?

Thanks a lot!

    Hi,

    There is a way to understand how the ar1 commands map to the device configuration.Fill in the configuration in mmWave Studio and then check which command is generated in the log window.

    For example for the ar1FrameConfig,

    See in Section 9.3 Frame Config.

    C:\ti\mmwave_studio_02_01_01_00\docs\mmwave_studio_user_guide.pdf

    In Figure 9.3, you can see in right hand lower corner the "Frame" box.

    The fields in this box will define the arguments of the ar1.FrameConfig() API

    Example

    ar1.FrameConfig(0, 0, 8, 128, 40, 0, 0, 1)

    • 0 - Start Chirp
    • 0 - End Chirp
    • 8 - No Of Frames
    • 128 - No Of Chirps Loops
    • 40 - Periodicity
    • 0 - Trigger Delay
    • 0 - Dummy Chirps
    • 1 - Software Trigger

    Unfortunately there is no detailed documentation for the ar1 commands.

    Thank you
    Cesar
