CCS/IWR1642BOOST: I want to display incoming data of distance on serial port of SAMD21G (arduino code) .

Part Number: IWR1642BOOST

Tool/software: Code Composer Studio

As coming data from AR_MSS_LOGGER pin is not in decimal.I wanted to display data in meter on SAMD21G serial port. I am taking that data in hex and after converting it in to meter i want to display that on serial window(docklight).But when i am connecting iwr1642boost board directly to SAMD21G it is unable to display that data.

But when i am entering that output data of distance manually by taking output data from AR_MSS_LOGGER pin on docklight  and then enter it manually on serial window of docklight. I am getting that output of distance in meters.I think there is a problem with the speed of iwr1642boost  & SAMD21G  because when i am processing that data in to my written arduino code of SAMD21G. It is stop displaying data from there.

    Hi Arpit,

    I've notified an mmWave Expert about your query and someone should have an answer for you sometime next week.

    Hi Arpit,

    We cannot comment-on/provide support on specific problems related to Arduino or other third party solutions in general. From the mmWave side, the UART ports are configured for specific data rates in software. In the SDK OOB demo, the control UART is configured at 115200 baud and the data UART is configured at 921600 baud as per the following code in mss_main.c

        /* Initialize the DEMO configuration: */
    gMmwMssMCB.cfg.sysClockFrequency = MSS_SYS_VCLK;
    gMmwMssMCB.cfg.loggingBaudRate   = 921600;
    gMmwMssMCB.cfg.commandBaudRate   = 115200;

    The only suggestion I can provide you is to make sure that the other board is configured at 921600 bps to be able to correctly receive the data coming from the mmWave data logger UART.

    Regards
