AWR1642BOOST: High Accuracy /Fluid Sensing Porting to SDK 3.6

AWR1642BOOST: SDK 2.x vs SDK 3.6 datapath difference

Part Number: AWR1642BOOST

Hello TI sensor team,

I'm still working on my porting of High Accuracy from SDK 2.x to SDK 3.6,

but I stuck on huge difference between SDK 3.6 and SDK 2.x, one of them is dss_data_path.c that only exist in SDK 2.x.

My question is :

1. In SDK 3.6 where this [SDK2x_path]#packages\ti\datapath\dss_data_path.c restructured to ? I guess in [SDK36_path] \packages\ti\datapath\dpc.

Is this correct ?

2. After I review xWR6843 High Accuracy which is said already SDK 3.5, the dss_data_path.c and code structure is same with SDK 2.x 

Can you help to explain ?

    Hi,

    Porting from an older SDK to a newer one does not mean updating the data path.

    It only means updating some APIs that may have changed in the newer SDK due to firmware update.

    These updates are usually listed in the SDK release notes, in the "Migration section"

    C:\ti\mmwave_sdk_##_##_##_##\docs\mmwave_sdk_release_notes.pdf

    We have an internal porting of the xWR6843 High Accuracy demo that runs on xWR1843 and uses SDK 3.5. I can provide it to you through private chat.

    Thank you

    Sounds great! 
    We need high accuracy run on SDK 3.x because we need CLI Calibration. 
    Looking forward your private chat.

    Thanks before

    Hi Cesar.
    I already ported HAM 1843 source to 1642.
    - Replace this SOC_XWR18XX to SOC_XWR16XX, and defined SOC_XWR16XX  on CCS Predefined Symbol both DSS, MSS.
    - How about RX antenna ?
       1642 has 2TX, 1843 has 3TX.
    - change other related defined from 18xx to 16xx.

    Hi,

    High accuracy demo uses only 1Rx and 1Tx. as shown in "high_accuracy_demo_18xx.cfg"

    channelCfg 1 1 0

    For the meaning of this command please see the mmWave SDK User Guide, Section "3. 4. Configuration (.cfg) File Format"

    Thank you
