IWR6843ISK-ODS: raw data download with MMWAVEICBOOST

Emanuele Cardillo

Part Number: IWR6843ISK-ODS
Other Parts Discussed in Thread: MMWAVEICBOOST, , DCA1000EVM, IWR6843ISK

Dear TI support,
I have recently bought an IWR6843ISK-ODS board with a MMWAVEICBOOST. I am interested in downloading the raw data (or the time domain data) for implementing post-processing algorithms. I am figuring out that other people employed the DCA1000EVM for downloading the raw data but I do not have it. I understand that the DCA1000EVM board is needed with IWR6843ISK (no ODS) but I hope that in my case, there is a solution for downloading raw data without the DCA1000EVM board.
Thanks in advance

Hello

Suggested solution for Raw Data capture is to use TI's mmWave EVM with DCA1000 board.

Thank you,

Vaibhav

Hello Vaibhav,

thank you for your answer. My problem is that I do not have the DCA1000 board and I am asking for an alternative solution. I do not need a real time download, it would be fine als to save the raw data in the PC for a further elaboration.

I am figuring out that the mmWave Demo Visualizer allows to save data but I do not know if you can save the data in time domain instead of the already processed data.

Sincerely,

Hi,

The out of box demo does not support raw data transfer from UART.

Other than using DCA1000 board, for ADC raw data capture, you can mem_capture test example under

C:\ti\mmwave_sdk_03_04_00_03\packages\ti\drivers\test\mem_capture

But this demo code save the ADC data in memory and you can run the code in debug mode to read out the ADC data. But it may only be one frame of data.

There’s also an App note on Raw Data capture and data format:

Dear Zigang,

thank you for your answer. I have another question that could help solving this issue. The mmWave Demo Visualizer allows to record and save data in .dat format. What kind of data are they? Are they complex time data or frequency domain data? In the first case, the could be used in place of raw data, isn't true?
Sincerely,

Emanuele

I clicked "This resolved my issue" accidentally within my email, it is not already solved...

HI,

The data stored by the OOB Demo online visualizer will be a .dat file. It stores the information sent out of the DATA COM port during sensor run. This is binary data that can be parsed to obtain the various TLVs exported by the demo. Data format is described in the OOB Doxygen documentation at:

file:///C:/ti/mmwave_sdk_03_04_00_03/packages/ti/demo/xwr68xx/mmw/docs/doxygen/html/index.html#output

YOu can see that ADC raw data is not an option in the output.

Best,

Zigang
