IWR1443: relevance and translation of *.json (Estimator) and *.cfg (Visualizer) -file

Johannes Sedlmeier

Part Number: IWR1443
Other Parts Discussed in Thread: MMWAVE-SDK

Hi,

my previous knowledge is that *.cfg-Files from mmWave Demo Visualizer differs from *.json-Files from mmWave Sensing Estimator.

The *.cfg-Files includes more general information, e.g. plot-settings for visualizing.

But if I understood it right, the *.json-files includes more detailled information about the chirps and the post processing process.

So i want to "translate" the part of the chirp-configuration from *.json-files to the *.cfg-files.

But to do so, I need a description of the *.cfg-files?

e.g. the command "channelCfg 15 5 0" from *.cfg-file:

Whats the meaning of 15 and 5 and 0?

my assumption is: RX channelEn / TX channelEn / cascading

but if this is right, I don't understand the relation betwen 15 and RX?!...

Does anyone have this information?

    Hello Johannes,

    Please refer to "Sec 3.5 Configuration (.cfg) File Format" in the  "mmwave_sdk_user_guide.pdf". This can be obtained from the MMWAVE-SDK.

    This gives the details of all the parameters of the .cfg file.

    Thanks,

    Raghu

    Hello Johannes,

    You will find a description of the cfg file in the SDK documentation under section 3.5 (ti\mmwave_sdk_01_00_00_05\docs\mmwave_sdk_user_guide.pdf), however some parameters are more thoroughly described in the Device Firmware Package (DFP) documentation. You may download the DFP here; the relevant document is ti\mmwave_dfp_00_07_00_04\docs\AWR1xx_Radar_Interface_Control.pdf,, chapter 5.

    There have already been questions on the same topic. You may read this post that explains the limitations of this conversion process. Thank you.

    Regards,
    François.
