AWR1642BOOST: Configuration parameters

Anum Pirkani
Expert 2005 points
Part Number: AWR1642BOOST

Hey,

I have a few questions regarding the configuration parameters set in Radar studio.

1) Why is the settling time set at preferably 99% is used for calculation of parameters in ramp timing calculator? 

2) Is there any suitable duty cycle value which should be set by controlling the periodicity?

3) In the Radar studio, .lua files are loaded. Can the .cfg files also be loaded in Radar Studio?

4) As per my understanding after going through multiple posts in the forum, using CCS, we can collect data for only one frame. Is this correct? If yes, is there any limitation on the number of chirps per frame?

 

Many Thanks

Anum

    Anum,

    Please refer to the SDK User's Guide, specifically section 3.4 that explains the the configuration file format. In the frameCfg section, it specifies the following information in the frame periodicity parameter:

    "Any value as per mmwavelink doxgen and represented in msec. However frame should atleast have 50% duty cycle and allow enough time for selected UART output to be shipped out (selections based on guiMonitor command)."

    Configuration files (.cfg) cannot be loaded in Radar Studio. These files are only used when sending the configuration over the command line.

    Please refer to the documentation for the now obsolete capture demo. There is a memory limitation which is why we can only capture one frame of data in CCS. And in reality we are not capturing the data, but viewing the data of the L3 memory buffer before it is sent out for additional processing. The configuration file for this lab was designed based on the known memory limitations of the device. If you are looking to capture more than a single frame of data, I would recommend looking at the DCA1000.

    Regards,

    Thanks a lot.

    It is clear now.
