mmWave Demo Visualizer

Other Parts Discussed in Thread: AWR1642

Hello! I installed a beta version of mmwave demo visualizer that allows to save a CSV file. My question is, how can i get this data without clicking the LOG START on the mmwave visualizer? I mean, after i power up my device, the datas will automatically saves somewhere in my PC. Is it possible? 

I am trying to make a collision avoidance project. That is why i need the realtime data. Also, is it possible to interface a certain actuators like a buzzer in my mmwave (AWR1642). 

This is the process that i want for my project. First, the sensor(mmwave) will detect the objects, then the visualizer will send me the realtime data, if the object detected is within the coordinates of collision, the buzzer or any indicator will actuate. Is this possible? Please help. Thank you!

    Hi,
    You can modify the mmWave demo Visualizer to capture the log at the beginning.
    Else you can use TeraTerm/HyperTerminal (serial tool) to send command from one instance to CMD COM port and capture the data log from another instance on DATA COM port.

    AWR1642 device provides many of interfaces like GPIO, SPI, PWM which you can use to control any external device (in your case buzzer).

    Hello,

    The OOB demo starts sending the point cloud data on the Data COM port immediately after the sensorStart command and it keeps sending it every frame (based on the configured frame rate in the configuration). As Jitendra indicated, you can modify the mmWaveDemoVisualizer code to start recording data right after sending the sensor configuration. The demo visualizer is a TI GUI composer You will need to install GUI composer and familiarize yourself with the development environment and javascript.

    As a faster solution, I would recommend you to look at the zone occupancy Lab which uses the point cloud data coming from the SDK Out of Box demo and provides a Matlab GUI to detect objects in different zones. The complete Matlab source code is provided for the Visualizer so you can modify it per your demo requirements.

    Zone occupancy detection - 14xx (select xwrxxxx in device selection at GUI start-up)

    Thanks

    How can i modify mmwave demovisualizer? Should i import it on the GUI Compposer?

    Hello,

    That's correct. You will need to import the project in TI GUI Composer to make any modifications to it. Please refer to the TI GUI Composer user guide at the following link for more details: dev.ti.com/.../index.html
