Compiler/AWR2243: How to capture live data from AWR2243 Cascaded RADAR

Sudharshan pathi
Prodigy 120 points
Part Number: AWR2243
Other Parts Discussed in Thread: TDA2, IWR6843ISK

Tool/software: TI C/C++ Compiler

Hi TI Team,

We are using AWR2243 Cascaded RADAR in our application.

We would like to know how to capture raw ADC data in live frame by frame and transfer to PC from AWR2243 Cascaded RADAR chip.

Could you please help to point out the code changes needed for this requirement? please share if any documents available for the same.

Could you please help to share if any documents available, to understand raw ADC data format of AWR2243 cascaded RADAR?



Thanks

Sudharshan

    Hi, Sudharshan, 

    There is no live capture, processing, display application example provided yet. However, using the Ethernet control and transfer examples we include with the DFP package and mmWave Studio, a simple configure, capture, transfer and application could be created. Please see my other response on similar questions here:

    Hi Randy,

    We would like to know, whether the above mentioned solution works in linux(ubuntu) host machines?
    In our usecase, we are using linux host machine for data processing.
    Please help to get the liive data capture support for linux host machine.

    Thanks

    Hi Sudharshan, 

    All of the mmWave Studio Cascade EVM connectivity examples we have published assume a Windows 10 OS and Visual Studio IDE environment. 

    However, the TDA2 system hosts an SSH server. So basic connectivity to the TDA2 file system can be done through SSH protocol, like with the SSH2 Library (https://www.libssh2.org/examples/scp.html). 

    So if the system were setup to continuously capture and store files, a host Linux system would still be able to grab those files off the SSD and process them locally. Framerate would be pretty low, but you could process in batches. 

    Another alternative is to utilize the Processors SDK radar examples and build your own capture application. Then you could fully control the MMWCAS-RF/DSP-EVM from your Linux host PC. 

    Thank you,

    -Randy

    Hi Randy,

    Could you please help to point out the source code, where frame data is getting stored in ssd?

    Here we can make the changes like, rather than storing in file, we can send data(frame by frame) to linux host through socket?

    Could you please help regarding this?

    We would like to know, Do we really need radar studio to configure EVM and to collect the data? Can't we do without radar studio like 60GHz systems(Eg: IWR6843ISK)?

    Thanks

    Hi Sudharshan, 

    Please read through the radar example application user guide located in the Processors SDK install here: \PROCESSOR_SDK_VISION_03_07_00_00\vision_sdk\docs\Radar\ProcessorSDKRadar_UserGuide.pdf

    Thank you,

    Hi Randy,

    We have gone through the above document but we didn't find much information about the data collection and storage for Cascaded RADAR.
    But we found, apps.out application is writing the data to the /mnt/ssd/Cascade_capture_22xx/*.bin files.

    Could you please help to get the source code for apps.out application and steps to compile the application to TDA2x board? We are planning open socket in application and send data to the host(linux) machine for live capture and further processing.

    Is our understanding correct?

    Thanks
    Sudharshan

    Hi Sudharshan, 

    We do not provide the source code for this project. But, the application we use for mmWave Studio data capture is based on the TDA2 Processors SDK radar examples. So that is the right place to start if you need to develop something customized for your needs. If you need help with the TDA2 Processors SDK radar examples please open up a new thread on the Processors forum here with a specific question: https://e2e.ti.com/support/processors/. 

    Thank you,
