IWR6843: About LVDS output at OOB Demo firmware

user244678

Part Number: IWR6843

I am planning the following modifications to the IWR6843 OOB DEMO firmware:

Output ADC Raw Data by LVDS before 1D-FFT.

That is,
ADC sampling
⇒ ADC Raw Dat LVDS output
⇒ 1D-FFT execution and Inter-frame signal processing are the same as in OOB Demo.

Raw Data output as LVDS is received by FPGA and used for debugging purposes.

Is it possible to output ADC Raw by LVDS before performing 1D-FFT?
The SDK version is 3.4.0.3.

Thanks,
Hitoyuki Taguchi

    Hi, Hitoyuki:

    SDK out of box demo already support ADC raw data output by LVDS lanes.   You can enable it by changing lvdsStreamCfg in configuration file.     

    You can find more document on the SDK users guide at 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 Zigang,

    Thank you for your reply.
    About LVDS output, I was able to confirm it in the SDK document and demo doxygen.

    Best Regards,
    Hiroyuki
