CC2340R5: How to monitor the Li battery level using CC2340R5?

Part Number: CC2340R5

Hi，expert.

I have a few questions.

How to test the battery monitor function？ Are there reference design and CCS example  available?
I use a lithium battery to power the CC2340,So an LDO or DCDC was used.
Can I still use the battery monitor function?

Best regards.

    Hello Baitao,

    Regarding the use of the Battery Monitor driver, you can see a good description of its functionality at the <SDK>\source\ti\drivers\BatteryMonitor.h file. In addition, you can find a more detailed explanation about the different driver functions inside the SDK: <SDK>/docs/drivers/doxygen/html/_battery_monitor_8h.html. There are two short examples: "Register a High Threshold Notification" and "Register a Range Threshold Notification and re-register in Callback".

    Let me know if this helps.

    BR,

    David.

    Hi   David，

    Your response was very helpful, thanks!

    I have read the documentation. So I assumed that it was the VDDS of the CC2340 that was being monitored.  When I use DCDC,Battery voltage cannot be directly monitored。

    Anyway, thanks a lot for clearing up the confusion。

    Best regards.
