IWR1642BOOST: Module UART data output

Andris Kuciks

Part Number: IWR1642BOOST
Other Parts Discussed in Thread: TIDEP-0090

Hello, 

I have a question related to raw data outputs.

I found out that via UART data that ar transmitted are  

this was mentioned in: file:///C:/ti/mmwave_sdk_01_01_00_02/packages/ti/demo/xwr14xx/mmw/docs/doxygen/html/main_8c.html#ac3a90335aea273ffb5d4cc76d780a55d

But according to TIDEP-0090 TM demo it says that:

 

But in : https://e2e.ti.com/support/sensor/mmwave_sensors/f/1023/t/646597?tisearch=e2e-quicksearch&keymatch=doppler%20index  it says that velocity is calculated.

The question: is the velocity calculated on the module and it outputs this parameter as raw data? Or is the velocity calculated in TM demo software and the module don't output detected object velocity?

    Hello,

    The Doxygen documentation in the mmWave SDK packages/ti/demo/xwr14xx/mmw directory refers to the mmw (out-of-box) demo firmware included with the SDK which is different from the Traffic Monitoring demo firmware. The mmWave SDK mmw demo firmware outputs the Doppler index from the mmWave sensor which can then be used to calculate the velocity as described in the E2E thread you referenced.

    The Traffic Monitoring demo firmware uses a different signal processing chain to perform the detection, grouping, and tracking of moving objects. It does calculate the actual doppler/velocity (in m/s) and sends it out from the sensor along with the range, angle, and track information. The Traffic Monitoring UART data format will be added to the user guide in the future, but for now you can look at the People Counting lab user guide which uses the same format.
