AWR1843BOOST: ADC data(I/Q signal) from awr1843boost with dca1000evm

Part Number: AWR1843BOOST
Other Parts Discussed in Thread: DCA1000EVM, AWR2243BOOST

Hello,

I've been working with the AWR1843BOOST paired with the DCA1000EVM for capturing ADC data (I/Q signals) using mmWave Studio and MATLAB on Windows.
However, I'm looking to transition to using this setup on Ubuntu 20 with ROS.

My goals are to:

1. Initiate the start trigger and end timing to capture ADC data (I/Q signals).
2. Configure radar parameters.

Could you provide guidance on how to integrate and use this radar system within the ROS framework on Ubuntu 20?

Additionally, I've also acquired the AWR2243BOOST with DCA1000EVM. Are there any existing ROS packages or solutions available that support these devices?

Thank you for your assistance.

    Hello,

    I would start with the ROS driver user guide.

    TI mmWave ROS Driver Users Guide

    This is old and based on Ubuntu 18, so you will probably need to do some additional effort yourself to get it working on the lastest ROS. 

    Regards,

    Thank you for your reply.

    I have already tried using the TI mmWave ROS Driver, which is compatible with Ubuntu 20.04 and ROS Noetic. It appears to be designed primarily for generating 3D point clouds, without the capability to configure radar parameters or access raw data directly.

    Is there any ROS node available that allows for the configuration, command and raw data extraction from the radar, similar to the functionalities provided by mmWave Studio or the MATLAB interface?

    Thank you!

    Hello,

    No, we do not have anyway to do this. The raw data is captured over the LVDS interface using the DCA1000EVM. It is not captured in real time, it is stored in memory on the DCA1000EVM and then sent to the PC as a .bin file at the end of the capture. We do not have anyway to interface the PC with the LVDS raw data interface for real time data acquisition.

    Thank you for your response.

    I know that real-time operation is not possible with this device.
    My query is specifically about whether it's feasible to use ROS to configure radar parameters (such as slope, range bins, frames, etc.) and to save the raw data in a bin file.

    I currently have an AWR1843BOOST with a DCA1000EVM, which has been functioning well with the mmWave Studio on Windows,
    allowing me to adjust radar settings and save the data as a bin file. And my goal is to implement a similar process using ROS on Ubuntu.

    Thank you.

    Hello,

    There may be some way to do this but as far as I know, we have never implemented this. I will loop in our software team to confirm.

    Hi,

    Sorry for the delay

    Unfortunately our team does not have experience with ROS.

    Here are the only resources we have available for ROS. I think in the past we have used ROS for a GUI but maybe not for configuration

    Thank you

    Cesar
