IWR1443BOOST: Valid values in CLI Command(mmWave configuration command)

Wonjin Eom

Part Number: IWR1443BOOST
Other Parts Discussed in Thread: IWR1443, IWR1642

Hello! I'm Wonjin Eom and I'm using IWR1443 EVM board. 

I want to customize the configuration command so control the radar front-end.

but, when I send the configuration command through demo visualizer, some error message appeared and I guess that the configuration command I made was not valid for my EVM.

So, I think my configuration command was wrong but I don't know where I should correct.

The Question is, where can I find some information about console message?  

I already checked page 20 of user's guide of SDK(both v1.0 and v1.1) but there was no information about valid value.

For example, I want to know how is the upper limitation of ADC sampling rate or slope constant.

Please let me know where can I find it.

    Hi Wonjin,

    I've referred your question to an IWR team member. Someone should have an answer for you shortly.

    Hello,

    When you get error messages after customizing the CLI commands there are several places to look for the range of the parameters.

    a) the IWr1443, IWR1642 have specific sample rate limits - these are in the datasheet

    b) depending on what you are trying to do with the Out of Box demo, or Data capture demo mmwave_sdk, there are ranges of operation.

    in the mmwave software, there are several document sources, there is a a user guide, Interface Control Document, and there is HTML documentation

       C:\ti\mmwave_sdk_01_00_00_05\docs - mmwave user guide - C:\ti\mmwave_sdk_01_00_00_05\docs

       Out of Box demo - doxygen - C:\ti\mmwave_sdk_01_00_00_05\packages\ti\demo\xwr14xx(xwr16xx)\mmw\docs

       Capture demo - doxygen -  C:\ti\mmwave_sdk_01_00_00_05\packages\ti\demo\xwr14xx(xwr16xx)\capture\docs

    The visualizer that receives the USB - UART data has a command, and a data stream.  The command stream is what is displayed on the terminal.

    If you get an error after sending the commands, this can be a formatting, or a calculated error.  You can use the mmWave Sensing Estimator or Radar Studio - Ramp Timing Calculator page to assist in setting custom chirp commands.   If we expect the visualizer to display data, we should save the visualizer program, and make small changes to isolate the problems.

    The mmwave Sensing Estimator, has limit checking to help with settings, but it starts with engineering parameters and calculates the CLI values.

    Regards
