CCS/AWR1642BOOST: How to transmit the detMatirx by LVDS?

Part Number: AWR1642BOOST

Tool/software: Code Composer Studio

I had read the PDF file of "AWR1xxx Data Path" , and traced the Demo Code of MMWave SDK 2.0.

Then, I know how to transmit the ADC Data to CBUFF by EDMA, and the EDMA was set by using the CBUFF_createSession function.

Now, I want to transmit the detMatrix of L3 memory to CBUFF , but i can't find the source address in the EDMA setting of LVDS.

I would like to know if I could change the source address in the EDMA setting of LVDS to the address of detMatrix.

Thank you.

    Hi Morris,
    mmWave SDK v2.0 provides an option to sent object data over LVDS if LVDS streaming is enabled.
    You can send other type of user data over LVDS by amending the source code
    dss_lvds_stream.c: MmwDemo_LVDSStreamSwConfig(): sessionCfg.u.swCfg.userBufferInfo[1].address = (uint32_t)datPathObj->detObj2D;

    Hi, Jitendra

    When I set the trigger of LVDS to software trigger, do I need to trigger it actively?

    And how to trigger it actively?

    If you wish to send user data then you need to trigger LVDS at every frame internal via software trigger as being done in mmw demo [dss_main.c: CBUFF_activateSession (gMmwDssMCB.lvdsStream.swSessionHandle, &errCode)].
