CCS/IWR6843ISK-ODS: iwr6843+DCA1000 ar1. JsonExport command issue

HI, Ernie:

The radar studio users guide mentioned that the json export should generate two output file XXX_setup.json and XXX_mmwave.json. 

Do you see both of them?  

Best,

Zigang

Hi, Zigang:

Yes, I can see the two output file XXX_setup.json and XXX_mmwave.json. 

The XXX_mmwave.json files are the same with using studio GUI and  ar1. JsonExport .

But the XXX_setup.json are different which I mentioned above.

Thanks 

Ernie

HI, Ernie:

Thanks for the response.  Due to the special situation, I do not have a DCA1000 board to try at the moment.  I will get back to you as soon as I get the board back.  At the same time, I will forward your problem to the design team.

Best,

Zigang

HI, Ernie:

Here is the response from the design team: 

The json files exported will only contain the configuration that are issued to the device and are successful/passed.

If the json file doesn’t have the DCA1000 Config structure, it means either it wasn’t issued or the configuration was not successful.

---------------------

Can you check whether your DCA1000 configure command is passed successfully?

Zigang

Hi Zigang:

I have check the DCA1000 configure command on Studio output screen, and the output is as following:

It seems that the DCA1000 has been set as we wish.

However, the JSON file still lose the DCA1000 Config structure.

We're using Matlab to control the Studio. Due to the using requirements, we separate the lua scipt into three parts. Does it cause the issue of JSON file?

Hi, Ernie:

After you going through these configurations, were you able to capture raw data successfully?

Best,

Zigang

Hi Zigang

Yes, after the configurations, the raw data is captured successfully; and can be used in our experiment with losing the DCA1000 setting information in JSON file.

Best, 

Ernie

HI, 

Looks like you are using Matlab to control the Studio. Can you try a stand-alone capture in the Studio session alone? 

Best,

Zigang

Hi,

I run the example of script in mmwave studio script folder with adding the JsonExport function after data capture, and the code is  as following 

json_path= "C:\\ti\\mmwave_studio_02_00_00_02\\"
json_setup_name = json_path.. "test1.setup.json"
json_mmwave_name = json_path.. "test1.mmwave.json"
if (ar1.JsonExport(json_setup_name,json_mmwave_name, "Ernie", "test1", "test1") == 0) then
WriteToLog("JSON File Export Success\n", "green")
else
WriteToLog("JSON File Export failure\n", "red")
end
RSTD.Sleep(2000)

The output of setup json file is following:

{
"createdByVersion": "2.0.0",
"createdOn": "2020-05-07T10:25:54.2047981+08:00",
"configUsed": "",
"captureHardware": "DCA1000",
"mmWaveDevice": "iwr6843",
"operatingFreq": 60,
"mmWaveDeviceConfig": {
"RS232COMPort": "COM3",
"RS232BaudRate": "921600",
"radarSSFirmware": "C:\\ti\\mmwave_studio_02_00_00_02\\mmWaveStudio\\Scripts\\..\\..\\rf_eval_firmware\\radarss\\xwr68xx_radarss.bin",
"masterSSFirmware": "C:\\ti\\mmwave_studio_02_00_00_02\\mmWaveStudio\\Scripts\\..\\..\\rf_eval_firmware\\masterss\\xwr68xx_masterss.bin"
},
"mmWaveBoard": "test1",
"mmWaveBoardId": "test1",
"capturedFiles": {
"numFilesCollected": 1,
"fileBasePath": "C:\\ti\\mmwave_studio_02_00_00_02\\mmWaveStudio\\PostProc",
"files": [
{
"rawFileName": "adc_data_Raw_0.bin",
"processedFileName": "adc_data.bin",
"processedFileSummary": {
"numZeroFillBytes": 0
}
}
]
}
}

It seems still lose the DCA1000 configure details.

Hi, Ernie:

Does this above experiment run through the radar studio GUI?  

Best,

Zigang

HI, Ernie:

I finally get a DCA1000 board to try myself.  It does show the similar information as yours.   I then went back to the users guide, and it does not mention that the json file will contain the IP address configuration for DCA1000.   

Best,

Zigang

Hi

Yes, all the experiments are controlled by Matlab and run by studio GUI.

Does this issue cause by controlling with Matlab?

Best,

Ernie
