IWR6843AOPEVM: IWR6843AOPEVM

Tool/software:

Hello,

I am using the Industrial Visualiser for the 3D people tracking demo and can see the point cloud movement as expected. I can also save the binary data to an output file as expected.

However, when I close down the visualiser and use the COM port instead, I cannot see any data being received and displayed in the terminal. Is the reason for this that once the visualiser is closed down the sensor no longer has the configuration file?

Essentially I need a way to view and stream the sensor data to the COM port - I am not able to see this at present.

Any help you could give me would be greatly appreciated.

Kind regards,

Kate

    Hello Kate,

    The visualizer does not prevent the EVM from running/stopping and works independently. The visualizer sends CLI commands via COM port on the CFG port, then reads in the data coming in from the DATA port. Data will continue to flow in from the DATA port as long as the device is on. When you say you close the visualizer and use the COM port, what do you mean exactly? Note that every time new configuration is to be ran the device has to be power cycled.

    Hello Pedrhom,

    Thank you for your response.

    I guess my question is that if the configuration file is sent to the sensor once, does this mean that any time after this that the sensor is USB connected it will send data relating to this configuration to the COM port?

    Also, is there a python script for parsing this data? I would like to parse the incoming data as a live stream, is this possible?

    Kind regards,

    Kate

    Hello Kate,

    Once a configuration file is sent and the sensor starts, it will continue to emit that configuration's chirp design until power cycled.

    You can definitely parse incoming data as a live stream. Although TI does not provide any scripts for this, it is not very difficult. You can read in the data coming in via Data Port, and use the "Understanding UART Data Output Format" document to understand the format of the incoming packets. Every packet will start with the frame header which starts with the magic word to sync and know it is the beginning of a new packet, followed by all the TLVs based on the example ran and output enabled
