IWR1843: Question on post processing in mmwave studio

Chris Meng

Part Number: IWR1843

Hi,

In mmwave_studio_user_guide.pdf of mmwave_studio_02_01_01_00, customer found below note.

NOTE: 1. Matlab post processing supports data capture only in following modes

a. 4 RX channel, 4 LVDS lanes

b. 2 RX channels, 2 LVDS lanes

c. 1 RX channel, 1 LVDS lane

But for IWR1843, it has 4 RX and only has 2 LVDS lane.

So does matlab post processing supports data captured by 4 RX channels, 2 LVDS lanes in mmwave studio v2.1.1.0?

I think the doc is not updated correctly. Pls kindly confirm.

    HI, Chris:

    Do you refer to the post processing script located at: 

    C:\ti\mmwave_studio_02_01_01_00\mmWaveStudio\MatlabExamples\singlechip_raw_data_reader_example

    I believe it is support both xwr1843, which is 4 RX, 2 LVDS lane; as well as xwr1443 which is 4 RX, 4 LVDS lane.   It is important to save the matching xxx.setup.json file in order to purse the data properly.

    Can you direct me to the documentation you mentioned?  

    Best,

    Zigang

    Zigang,

    No. I mean the postproc integrated with mmWave stuido GUI.

    Hi, Chris:

    Thank you for your feedback.  This part of the users guide are all only related to xwr12xx/xwr14xx type of device.  It does not include the information for xwr1642/xwr1843/xwr6843.   I will submit a ticket for this. 

    Best,
