Hi,

I would like to know the data rate of the UART that is used to send data to PC?

Best regards,

    Hi Divya,

    UART data rate is mainly depends on the baud rate and the no. of bit it samples at every baud.

    WIth 921600 baud rate (8-bit), data rate is around 921KBps.

    Please refer the mmw demo where UART baud rate is being configured.

    Hi,

    I do understand the recommended baud rate in Demo visualizer is 921600,but our application requires a baud rate of about 115200 for data port.

    We changed the data port baud rate to 115200 in Demo visualizer ,but unfortunately the GUI didn't plot any graph.

    1) Is this issue due to baud rate mismatch?

    2)How can we obtain data at baud rate of 115200?.

    Best Regards,

    Divya Harikumar

    Hi,

    The data baud rate of 115200 will not be sufficient to send some of the demo data to the visualizer.

    The Visualizer is validated with 921600 baud rate.

    You may want to try sending only the range profile and check if it works.

    Since this is not the use case supported out of the box we would have to wait for additional support from the forum community

    thank you

    Hi Cesar,

    We were thinking of communicating output data frame from each of the four AWR1642 devices through a CAN network.

    As u suggested.if we require a min.of 921600 Baud for demo data from each device then,how is it possible that we can communicate multiple devices through a CAN network whose max.data rate is 1Mbps?

    Regards,

    Hi,

    CAN is a different interface that supports much higher bandwidth than UART.

    As I mentioned in previous e-mail. Disable all the buffers sent from AWR to PC Host in the profile configuration using "guimonitor" command and try it.
