CC1352R: TI 15.4-Stack power calculator

Pranav 3

Part Number: CC1352R
Other Parts Discussed in Thread: ENERGYTRACE

Hello,

I am using cc1352R with SDK 4.30

I want to calculate power consumption and battery lifetime.

Earlier there is a Power calculator Excel spreadsheet for devices utilizing the TI 15.4 Stack.

In the release note of SDK 4.30, there is one point in What's new
i.e. TI 15.4-Stack power calculator can be used to calculate power consumption and battery lifetime.

But I can't find any ready to use example or any hooks for the TI 15.4-Stack power calculator.

So, Can you please guide me, Where to tap in?

Thank you,

Pranav.

    Hello Pranav,

    You can find the 15.4-Stack calculator and instructions at simplelink_cc13x2_26x2_sdk_4_30_00_54/docs/ti154stack/TI-15.4-STACK-CALC.html

    Hello Ryan,

    This calculation is supposed to be a tool or TI-RTOS /15.4 stack code lib/utility that will do the real-time calculation/ battery life estimation from within the cc1352R code?

    Regards,

    Pranav

    Hi Pranav,

    This is a standalone software tool that estimates power consumption and battery life of 15.4-Stack applications, it is not associated with the 15.4-Stack SDK code.  If you want to evaluate the actual power consumption of your application firmware then I suggest you use a precision multimeter, power analyzer, or ENERGYTRACE on your hardware operating the code during runtime.

    Hi Ryan,

    Would it be possible to (as Pranav seems to be suggesting)  - monitor raw/ net (RX+TX) RF activity and apply this info overtime to estimate power consumption/ batt use?
    (I'm guessing) perhaps something like this may be already taking place in low-level RF driver(?)

    Would it be practical to tap into driver code areas for either accumulated activity timer counts or raw RF IO activity (to accumulate it over time) as a measure of estimated-
    current draw/ batt. life?

    Please advise. Thanks.

    Best,
    SE

    Hi SE,

    There is no solution already in place for this purpose, once more I would expect ENERGYTRACE software to be used instead.
