AWRL1432BOOST: Runtime temperature calibration

Part Number: AWRL1432BOOST
Other Parts Discussed in Thread: AWRL6432

Tool/software:

Hello TI experts,

I'd like to calibration of temperature runtime in non-low power mode.(mmw_demo example)

Temperature calibration is performed after cold reset, deep sleep exit due to MMWave_openLink() function in low-power mode init state.

In Non-low power mode, the processing is executed in the while loop of dpc_excute() in dpc.c.

If I use MMWave_openLink() function in dpc_excute(), can I do runtime temperature calibration when non-low power mode?

Thank you.

Best Regards,

JB

    Hi,

    It is not possible to call openLink() inside the dpc_execute(). One would need to call the temperature calibration directly inside the dpc_execute() at the end of the processing

    Thank you

    Hi, Cesar

    In openLink(), temperature calibration feature is implemented. 

    1. Set the Temperature measurement configuration

    2. Call rl_fecssTempMeasTrig API, 

    3. Compare temperature current bin and old bin.

    4. Call rl_fecssRfRuntimeCal () <- this function is temperature calibration trigger.

    (Please let me know if I'm wrong)

    If use the rl_fecssRfRuntimeCal() function, it seems like you need to do 2 and 3 first.

    Does 'One would need to call the temperature calibration directly' mean that I need to create the temperature calibration function using above  2,3,4 functions ?(In non-low power mode, 1 is already set before dpc_excute()) 

    or Is there other function for the temperature calibration?

    Thank you.

    Best Regards,

    JB

    Thank you

    In order to understand how to use these APIs, here is the reference document.

    C:\ti\MMWAVE_L_SDK_05_05_03_00\firmware\mmwave_dfp\docs\mmwave_dfp_interface_control_document.pdf

    To measure the temperature there are 2 APIs to be used:

    • rl_fecssTempMeasCfg()
    • rl_fecssTempMeasTrig()

    There is a simple example that shows how to use it

    C:\ti\MMWAVE_L_SDK_05_05_03_00\firmware\mmwave_dfp\examples\source\rlexample_tempmeas.c

    You will notice that this is not related to the Run Time Calibrations

    thank you

    Hi, Cesar

    • rl_fecssTempMeasCfg() : This API configures for temperature measurement
    • rl_fecssTempMeasTrig() : This API triggers measurement

    Calculation and compensation for temperature changes are required after measurement.

    What is the function that does that?

    Does rl_fecssTempMeasTrig()  API compensate for temperature changes?

    Thank you.

    Hi,

    I think there is some confusion. The compensation related to the temperature change is performed by run-time calibration and it is automatic. It only has to be enabled.

    The APIs related to measure the temperature are not used for compensation, only for reading temperature information.

    thank you

    Hi, Cesar

    Sorry, I typed wrong sensor. I am using AWRL6432. The process maybe different. so my question is confusing.

    I will close this question and ask to AWRL6432.

    Thank you.

    Best Regard,
