Other Parts Discussed in Thread: IWR1443BOOST, IWR1642BOOST

Tool/software: TI-RTOS

Hi Ti Guys，

We kick off new product using Ti mmwave sensors.Now I have some questions listed .

1.I need to fork new task to get range,velocity and angle.So how to fork new task in MSS?Do you provide sample code ?How to get range, velocity and angle in the code?

2.For different RCS,such as pedestrian, car or motor, the sensor need to dectect at the different ranges.How to design this scenarios. Which ti demo are closet to this scenario？

Thanks

    Hello,

    1. The mmWave SDK Out of Box demo provides point cloud data with range, velocity and angle of arrival associated with each point. You have not mentioned which mmWave EVM are you using but the Out of Box Demo comes pre-installed on both the IWR1443BOOST and IWR1642BOOST EVM. Please refer to the Getting Started section of the mmWave SDK user guide available under <mmwave_sdk_install_dir>\docs\.

    We also have the mmWave ROS Point Cloud Visualizer Lab available under mmWave Industrial toolbox on TI Resource Explorer. This lab provides an example of integrating the mmWave Sensor Point Cloud with the Robot Operating System. It uses the SDK Out of Box Demo mentioned above, and takes the point cloud data coming from the EVM over the USB-serial port and allows for mmWave radar point cloud visualization using the RVIZ visualizer available in ROS. The SDK Out of Box demo as well as all the demos available under mmWave Industrial Toolbox are provided with complete source code and build instructions.

    2. The configuration of mmWave Sensor according to the scenario requirements (Max range, Max velocity, Range resolution, etc) is done using chirp parameters and TI provides the mmWave Sensing Estimator Tool for this purpose. The Sensing Estimator takes the scene requirements such as max. range, max velocity etc as input and outputs the corresponding chirp parameters. Please refer to the following thread for more details on the overall mmWave application design process.

    Please mark this thread resolved if your question was answered otherwise get back if more support is needed.

    Thanks
