Dear TI
I’m attempting to use the IWR1433 vital signs demo to get the breath signal.
In the developer’s guide, it is said that each frame is configured to have 2 chirps and only the 1st chirp in the frame is used for processing. So, I think if all frames are sent to my PC, the frame index I get should be continued.
However, when I use vitalSigns_demo_gui.m to run the vital signs demo and print the frameNumber (in Matlab code is named globalCountTemp) in the frame header, I find that the frameNumber isn’t continued.
The difference between the globalCountTemp is shown below:
The difference between each frame index is fluctuant, not always stay 1. I calculate the time T = (the last Frame index-the first frame index)/20fps, the T is correct with the real run time. It makes me confused, for example, where are the frames between frame 13th and frame 21st? Missing or hidden? How can I get all the frames?
Thanks a lot for your help!
