Original question:

IWR6843: How to bring ADC data over LVDS

IWR6843: How to bring raw data to custom hardware using IWR6843AOPEVM?

Part Number: IWR6843
Other Parts Discussed in Thread: MMWAVEICBOOST

Hi,

I was able to connect the IWR6843AOPEVM to the MMWAVEICBOOST and DCA1000 to get raw data off the device.

Now, I would like to connect the IWR6843AOPEVM to my own custom hardware (using the same high density connector used with MMWAVEICBOOST) to live stream raw ADC data into my hardware. Is there any documentation on the high density connector and how it can be connected to custom hardware? I did run into ticket (https://e2e.ti.com/support/sensors/f/1023/t/782341) which was asking a very similar question about getting the raw data without using DCA1000 but looks like it was resolved through direct communication with the ticket creator and I am unable to determine how that issue was resolved.

Any help you can provide on getting the raw data into my hardware, using the IWR6843AOPEVM board would be greatly appreciated. 

Cheers,

    HI, 

    Do you mean you want to get raw ADC data out without DCA1000?   If so, you can look at below link for CSI streaming

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

    I will consult with that ticket owner and get back to you.  

    Best,

    Hi, 

    I got feedback regarding the thread you mentioned  (https://e2e.ti.com/support/sensors/f/1023/t/782341), they are actually doing LVDS data capture without radar studio.  But they are still doing LVDS data capture through DCA1000 capture board.  

    Right now, SDK 03.03.00.03  and radar studio together support raw data collection through LVDS and DCA1000 CLI control interface. 

    You can find some document on the SDK users guide on DCA1000 CLI control interface on section 3. 3. 2. mmWave demo with LVDS-based instrumentation.   The SDK users guide is located at: C:\ti\mmwave_sdk_03_03_00_03\docs

    You can also find some guide on radar studio package located at: C:\ti\mmwave_studio_02_01_00_00\mmWaveStudio\ReferenceCode\DCA1000\Docs

     The basic idea is to run SDK out of box demo on the target EVM. The out of box demo will detect point cloud and at the same time send out ADC raw data through LVDS.   At the same time users will use DCA1000 CLI control interface to control the DCA1000 to get data capture through LVDS lanes.

    Let me know if this answers your question.

    Best,
