IWR6843ISK-ODS: Real time high speed transmission using IWR sensors

Part Number: IWR6843ISK-ODS
Other Parts Discussed in Thread: IWR6843

Hi, 

I am using IWR6843 with DCA1000 for data collection. I have been able to save the data successfully using mmWave studio.

However, i wanted to know if there is a way to receive the data in the real time continuously without using mmWave studio. I would like to improve the data rate from the current baud rate of 921600 to use the sensor in the real time environment.

Can someone suggest me a way to utilize the DCA1000 without using mmWave studio and use the SPI and ethernet capability for real time continuous data trasfer?

Thank you,

VK

    HI, VK:

    We do not offer a complete solution or example for real-time demo.    Mmwave SDK and radar studio together provide a method to capture raw ADC data through LVDS without radar studio.   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 captured through LVDS lanes.

    In this platform, the raw ADC data is coming through LVDS real-time.  However, the DCA100 CLI control interface only support to save the data into a file.   So, it is not the exact solution you are looking for.     Instead advance users need to come up with their version of the application to communicate with DCA1000 board.   The source code of DCA1000 CLI control interface as well as its DLL libary are all available at:

    C:\ti\mmwave_studio_02_01_00_00\mmWaveStudio\ReferenceCode\DCA1000\

    Users can also find some document on the SDK users guide 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

    Best,

    HI VK

    Breaking down the query in sub steps:

    1. Streaming without mmWave Studio :  Please see mmWave SDK OOB demo for LVDS streaming option.

    2. Improving Data speed:  LVDS Data for  capture utilities to avoid packet drops. Device can let you go upto 900Mbps per lane.
