Compiler/AWR1843BOOST: Capture Data

Paolo Care

Part Number: AWR1843BOOST
Other Parts Discussed in Thread: AWR1843

Tool/software: TI C/C++ Compiler

Hello,

my name is Paolo and i'm working with the AWR1843BOOST EVM now since a few weeks.

Currently  i would like to use the EVM to make some long time meassurments. Since in my application the data transfer over the USB-Port seems to be complicated i was searching, fr other possibliliys to capture the object data as range, velocity and posision of objects, which are used for example in the labs provided by Texas Instruments (mmwave_automotive_toolbox).

As i saw the EVM provides a LVDS interface. Is there any posibillity to use this interface or something else like CAN, to capture data?

Is there any example or reference?

Best regards 

Paolo

    Hello Paolo,

    Most of Lab example streams the object result from the mmwave sensor. This data can be sent over UART/CAN or even LVDS.

    This lab example provide a reference where it sends object results over CAN

    http://dev.ti.com/tirex/explore/node?node=ADWAvz1GWDvSfSVkncqhEw__AocYeEd__LATEST

    And default OOB demo from mmwave SDK provides an option to stream the raw ADC data over LVDS and object result can also be added to this interface.

    Please refer the mmwave_sdk_user_guide.pdf for 'lvdsStreamCfg' CLI command which has an option to stream user data as HSI header.

    Hello Jitendra,

    thanks for your fast answer.

    I have just two additional  question about the CAN Interface.

    1. Is it also possible to sent data over the CAN Interface for configuration ?

    For example to change the chirp sequenz or the Tx/Rx configuration?

    2. Is there any difference between the data provided by CAN and UART?

    Best regards

    Paolo

    Hello Paolo,

    1. Yes, it is possible to send configuration data to device over CAN. Refer to the above-given application or the CAN test application in mmWave SDK where it receives the data over external CAN.

    C:\ti\mmwave_sdk_03_03_00_03\packages\ti\drivers\can\test\common

    2. Data from AWR device by CAN and UART will be the same when it is received at the other end over this interface.

    Regards,

    Hallo Jitendra,

    thank you really mutch that was exactly what i  was looking for.

    I have just one last question abaut the LVDS Interface. 

    Is it necessary to use a DCA1000 device to capture the raw Data?

    Best regards

    Hello Paolo,

    To capture over LVDS that is the hardware TI provides. You can build your own board which supports LVDS interface to capture the raw adc data from AWR1843 device.
