IWR1443BOOST: EVM boards.

Part Number: IWR1443BOOST
Other Parts Discussed in Thread: IWR1443, , MMWAVE-SDK

Hello TI team,

   I want to work with multiple IWR1443 BOOST EVMs sensor boards and I need following information.

        IWR1443:  (1) Can four sensors/boards be used simultaneously? Under what conditions one boards will start interacting with other boards?

                          (2) Can I synchronize or cascade these four boards using some kind of trigger or other mechanism? 

                          (3) How can I acquire data from all four boards? I mean, can it be done by using single platform like Matlab on same machine (Computer)?

Please reply.

Thanks.

    Hi Amar,

     (1) Can four sensors/boards be used simultaneously? Under what conditions one boards will start interacting with other boards?

    The IWR1443BOOST EVM provide point cloud data over UART. If you need to use data from multiple sensors, some external processing entity (FPGA, Processor or PC) will need to take the individual UART streams and combine the individual point clouds per the requirements of the application.

       (2) Can I synchronize or cascade these four boards using some kind of trigger or other mechanism?

    If by synchronization, you mean starting/triggering the sensors at the same time then yes, you can use the hardware trigger feature to trigger the frames using Hardware Trigger through an external signal (SYNC_IN). Note however, that this feature is not supported at the MMWAVE-SDK demo level. This should not be confused with Cascading however, which is a specific technique for synchronizing multiple mmwave sensors at RF level so that they behave as a single sensor. IWR1443 does not support cascading.

       (3) How can I acquire data from all four boards? I mean, can it be done by using single platform like Matlab on same machine (Computer)?

    Addressed in question 1 above. Each sensor sends it's point cloud data on a UART port (over USB) so you will need to collect the data from the respective UART ports on your PC. We have not tested multiple sensors with one PC so if there are issues wrt UART communication from multiple ports, you'll need to work on those.

    Thanks
