AWR2243: How to adjust AWR2243 configurations

Part Number: AWR2243

When AWR2243 is working and I want to adjust its configurations at this point, can I do that?

Do I need to stop it from working first? Is there some documentation about this? Thank you.

    Hi,

    May I know what kind of configuration you want to adjust during runtime?

    Thanks,

    We want to switch long range mode and medium range mode in realtime running which require to change some of the radar parameters such as time of chirp, slope, start frequency .e.g

    Hi,

    The advanced frame configuration allows you to have such flexibility. An advanced frame consists of multiple sub-frames and each sub-frame can represent a different radar mode. Use rlSetAdvFrameConfig API to enable this kind of configuration. 

    For maximum flexibility -
        - an adv frame can be divided into 4 sub-frames,
        - one sub-frame can have upto 512 bursts of chirps
        - one burst can further accommodate 512 unique chirps and
        - a set of bursts can be looped upto 64 times 

    In each sub-frame you can configure chirps differently to achieve different radar modes. But, this configuration is done before triggering the frames.

    And the Dynamic Chirp Configuration gives you flexibility to update chirp parameters during runtime. Use rlSetDynChirpCfg API to enable this kind of configuration.

    Please refer to DFP User Guide (mmwave_dfp_02_02_04_00/docs/mmwave_dfp_user_guide.pdf) for further details.

    Thanks,
