IWR6843AOPEVM: DCA1000 + CLI command + mmwave demo visualizer

Hi Pedrhom Nafisi,

When I try during collecting of data or during parsing?

Kind regards,

Fahad

Hello Fahad,

Make this change before sending the CFG file to the sensor.

Hi Pedrhom,

Sorry for being late. I tried it.

Can you try doing LvdsStreamcfg 1 1 1 1

But I got an error which is shown below.

I load this profile to mmwave demo visualizer but I got this error. Profile.cfg is attached as well.

7178.profile_2d.cfg

kind regards,

Fahad

Hello Fahad,

Is there a reason you are trying to do lvdsStreamCfg when running the mmWaveDemoVisualizer? The lvdsStreamCfg line is specfically for pulling raw data and utilization of the lvdsStreamCfg command assumes that you have a host processor (DCA1000) actually capturing this LVDS data stream.

I just clicked on load config from PC and send as shown below, and then load the profile.cfg as attached above. Then it gives me this error(as shown above).

But when I used the same profile.cfg for parser and then set LvdsStreamCfg -1 0 1 0 , it gives me the following output as in text file. But the sw_output.csv

is empty just with headers.

Hello Fahad,

What happens when you remove the LvdsStreamCfg line and run that same cfg? Does that still give you an error/issue? Again why do you want/need LVDS streaming when using the mmWave Demo Visualizer?

Hello Pedrhom,

Pedrhom Nafisi said:

Yes, I got an error of: "Error: Invalid lvdsCfg_headerEn_buf[0]"

Pedrhom Nafisi said:

Actually with DCA1000 CLI command it gives me a log file as well in which there is good details and also Timestamps or overall duration of data collection. which is good for me in my case.

Otherwise by record button it works well I got output through parsing script but no enough details about timestamp or duration.

Kind regards,

Fahad

Hello Fahad,

Can you provide me with the LVDS_Example script you are currently using? I think that will help me with the context of what you are doing.

So correct me on my logic here, are you saying that you are running your profile_2d.cfg through mmWave Demo Visualizer and it works, but then when using the same CFG for DCA1000 with that LVDS_Example it does not work?

Yes that's great I'll attached it here.

No in both situations it works and store bin file. but without DCA1000 it didn't give me the log file but with DCA1000 it give me which is important in my case. An example of log file is attached here.

datacard_record_Raw_LogFile.csv

oh my mistake. Yes this is correct it works with visualizer but for LVDS_example it gives me errors.

Hello Fahad.

Pedrhom is out of office and will be able to provide an answer next week.

Sincerely,

Santosh

Hello Santosh,

No worries. Thank you for the update.

Kind regards,

Fahad

Hello Fahad,

So I am not too familiar with this LVDS example script that you have given me, is it possible for you to show me where you got it from? Also was there any default configuration files given alongside it? I see that the script is from 2020 so it is possible that there are some version mismatching going on here which is causing compatibility issues.

Best Regards,

Pedrhom Nafisi

Hello Pedrhom,

Pedrhom Nafisi said:

Thank you for your response. I got this script from "C:\ti\mmwave_sdk_03_06_00_00-LTS\packages\ti\demo\parser_scripts" as you know about sdk. 

Pedrhom Nafisi said:

Also was there any default configuration files given alongside it?

Yes, and I used the default cfg file and load to mmwave demo visualizer. It gives me an error about unrecognized line of bpmcfg -1 0 0 0 then I removed this line and load again and it works for demo but after some the demo stops and didn't work well. 

Pedrhom Nafisi said:

So can you please help me with that as well. What can I do now Can I download older version of python or what else?

Kind regards,

Fahad

Hi Fahad,

When you used the scripts linked above, what firmware was flashed onto the mmwave device?

Best Regards,
Alec

Hi Alec,

I only flashed the xwr6843AOP_mmw_demo.bin file and then run mmwave demo visualizer https://dev.ti.com/gallery/view/mmwave/mmWave_Demo_Visualizer/ver/3.6.0/.

Kind regards,

Fahad

Hi Fahad,

To be clear on the problem, you are trying to take a provided config (looks like profile_2d) and add the simultaneous LVDS streaming, correct? Could you share your full cfg here and the error you currently see? We can then provide feedback on if any settings need to be updated

Alec May said:

Yes but some time I also used the cfg downloaded from mmwave demo visulizer.

Alec May said:

Yes sure. If you read and see this thread from the start I explained all the things in details including cfg files and errors. Including the things related to LvdsStreamCfg.

Kind regards,

Fahad

Hi Fahad,

Have you gone through and followed all steps in the section of the mmWave SDK user's guide titled mmWave demo with LVDS-based instrumentation? There are some steps here to help configure the DCA1000 that I have not seen you mention thus far in the discussion.

Best Regards,
Alec

Hi Alec,

Let me explain step by step.

1) I flashed the bin file using uniflash for mmwave demo visualizer.

2) Then open mmwave demo visualizer on google chrome and select ports and my device.

3) Then load config from PC or some time directly send config to device and device starts sensing and I see the plots.

4) I already connect DCA1000 during experiment and using CLI command I able to capture the data saved in bin file through DCA1000 along with log file.

5) I then opened the python LVDS script as indicated above and give cfg file and data prefix and run the script and get the above errors when changing LvdsStreamCfg command.

Regards,

Fahad
