CCS/AWR1642: Config by frameCfg command via UART port based on People Counting Project

Part Number: AWR1642


Tool/software: Code Composer Studio

Hi E2e,

I would try to send the CONFIG CLI command via UART port by my external processor for changing Frame Periodic Time purpose only

First, the AWR1642BOOST had been configured and working well based on People Counting Project

Second, then I would like to change the Frame Periodic time from 50 ms to 200 ms

by sending simple three command lines via CONFIG UART port and got the response as followings,


mmwDemo:/>sensorStop
Done

mmwDemo:/>frameCfg 0 1 128 0 200 1 0
Done

mmwDemo:/>sensorStart
Done

mmwDemo:/>

Third, after above response messages received then AWR1642BOOST seems hangs on somewhere it did not work anymore

I had tested by the same config method on both of  VITAL SIGNS and HIGH ACCURACY projects working well

why does not work on PEOPLE COUNTING project?

 

Best Regards,

Kevin

    Hi Kevin,
    This command flow requires specific re-initialzation at the MSS and DSS application which may not be available under each of TI-Rex application.
    As at many application expectation to run the application only once and don't change the configuration at any time till next power cycle and send CLI command again from scratch.

    If you really needs this re-configuration feature in perople counting application then you need to compare this with other application and take those changes which will help to suport this feature.

    Hi Jitendra,

    I would try to re-configurate with LARGER frame periodic time for plotting animation drawing by Python programming on HDMI supported screen based on Single Board Computer

    How to manipulate the DSS program for a little bit changed on frame periodic time for above purpose?
    or can I use a hardware pin reading to set specified frame period time value?

    Regards,
    Kevin

    Hi Kevin,

    Currently, the People Counting Signal chain does not support reconfiguration after it has been started. This chain has been optimized to maximize the size of the Radar Data Cube, which means we are not able to reconfigure without a reboot.

    If you can send an NRST command to the device, you can resend the whole configuration with the changed frame rate.  To send NRST, a GPIO pin should be connected to the NRST input.  Then, setting this high will reset the device.  You could add a cli command the MSS/cli.c to set the GPIO high.  Once the device reset, the gui will need to send the whole configuration again.
