CCS / IWR1843： Using iwr1843 alone to get raw data

user6248969

Part Number: IWR1843

Tool/software: Code Composer Studio

I want to get the original data through a single iwr1843 board. I have used MEM capture. At the same time, I see some data in the memory browser, but it seems that I can't refresh the data. After running, it will freeze

My steps are 1. Import xwr18xx ﹣ ccsdebug.bin through unifish

2. Import xwr18xx? MEM? Capture? Dss.xe674 and xwr18xx? MEM? Capture? Mss.xer4f through CCS

3. In the memory browser, you can see that the data address starts from 0x20000000

I would like to ask

1. Is my step right?

2. How to modify configuration parameters?

3. Is there any way to modify the code to export multi frame data? I don't know how to modify it (novice)

4. I just want to use iwr1843 as a board to get the original data. Is there any other way besides MEM capture?

Thank you

HI,

For raw data capture, you can consider using connect radar EVM to DCA1000. There are two approaches:

1) Using radar studio to do data capture. You can download the latest radar studio and followed the users guide. It is a GUI based data capture. You can change all the parameter in the GUI.

2) Using DCA1000 CLI control interface. You can search for lvdsStreamCfg in SDK users guide, section 3.3.2. located at: C:\ti\mmwave_sdk_03_03_00_03\docs\mmwave_sdk_user_guide.pdf.

Both these two methods provide ways to change the chirp configuration.

Best,

Zigang

I know what you said about using dca1000, but I want to use iwr1843 as the board to get the original data and save it. Is there a good way?

HI,

In that case, you will need to stay with the mem_capture test example under

C:\ti\mmwave_sdk_03_03_00_03\packages\ti\drivers\test\mem_capture

You can find the doxygen document under

file:///C:/ti/mmwave_sdk_03_03_00_03/packages/ti/drivers/test/mem_capture/docs/doxygen/html/index.html

And beyond that, you may need to change the code yourself to achieve advanced goals.

Best,

If I need multiple frames of data, I need to modify the code, right?
Then I can use C: \ Ti \ mmwave \ SDK \ 03 \ 00 \ packages \ Ti \ demo \ xwr18xx \ MMW
By modifying the internal code, capture the original data?

Hi,

The demo code inside C: \ Ti \ mmwave \ SDK \ 03 \ 00 \ packages \ Ti \ demo \ xwr18xx \ MMW and the mem_capture test example are two independent test code. By modifying the mem capture demo to support multiple frame capture does not mean that you can use the demo code to capture the original data.

Can I modify the mem capture code to refresh and save at regular intervals?

Hi, there:

The mem capture code will keep capture the raw ADC data until the memory is full. So depends on your chirp configuration (like number of ADC samples per chirp and number of loops per frame), you may be able to capture multiple of frames. But that is all you can do.

Zigang
