AWR1642BOOST: Time between each tracker frame for SRR demo

Part Number: AWR1642BOOST

Hi I am using the srr demo but I am not sure how I can get the time between each frame for trackers? I looked into the GUI code and saw getStatsInfo(bytevec, idx) where it looks like it is getting the info from the MmwDemo_timingInfo_t struct in the firmware, but the code never gets to that part so I am wonder if there is any other way of doing it? I am trying to get the Acceleration by doing (v(t) - v(t-1)) / time taken since acceleration is not provided with the demo

Thanks

  • Hi Zhikai,

    One thing I could think of is using the frame number sent with each message header (see MmwDemo_output_message_header structure). Since the frame periodicity is known beforehand, it can be used to calculate the time elapsed between two tracking reports. As far as I know, there is one message per frame anyway, so the message periodicity should also be the same as the frame periodicity.
