IWR6843ISK: Connecting radar to external components

Part Number: IWR6843ISK

Hello,

I am working on a project similar to the one in the following video: www.youtube.com/watch

I need more details and support on the type of LED used here and how to interface between the LEDs and the radar board.

Thanks

  • Hi Zahra,

    I believe it was a simple LED tower light that is triggered by the result of post-processed data from the sensor. The LED component is almost completely external to the mmWave device.

    Would you be more specific about what you are trying to do?

    Regards,

  • Hi AG,

    I am intending to use a) the IWR6842ISK radar board, specifically the people counting demo, b) the Tiva LaunchPad. My aim is to connect the two boards together such that data is taken from the radar, for example people distance and people count, and based on the data corresponding feedback is implemented by the Tiva LaunchPad. Let us take an example scenario for clarification: there is a person standing less than a metre away from the radar. TheTiva LaunchPad recieves this data from the radar and decides to trigger the red LED.

    My questions are: Which IDE is better to use in this case? How to integrate the source code of both boards together? How to send data from the radar to the launchPad? 

    Can I also get some guidance on the hardware implementation if I would connect an LED tower light and a buzzer to the Tiva LaunchPad?

    Regards,

    Zahra

    Hello Zahara,

    The intention of the forum is to support the mmWave side. The LED is not specified as the intention is to leave integration and application issues such as type of LED and how to trigger to the user.

    There are many ways to connect to and control LEDs. I would recommend consulting external resources. If you're specifically interested in tower lights there are versions that include the lights as well as a buzzer. Typically, the tower lights come with wiring and control details specified the manufacturer.

    Whether you choose to use another launchpad to interface control commands is up to you. The application code is available for the mmWave sensor for you to modify. Note that you could easily use the serial output or GPIO pins available on the mmWave EVM.
