How to get battery power ?

[yaoxingshan]

The development board I am using is FRDM-KW41Z.

Is there any API related to reading the power supply voltage in the SDK package?

Thank!

Hello, 

Are you looking to use a specific protocol ? Are you looking to use Thread? 

You can check for example in the reed example the API called BOARD_GetBatteryLevel ? Does that work for you ?

Hello there,

I am using a Thread Stack.

Does the API need to set the power mode to a specific mode?

I saw in the manual that the DCDC module needs to configure the registers to connect the DCDC module to the ADC channel, so do I need to write the registers separately?

Thank！
