Use arduino primo to measure battery voltage level

[TTN]

Hi,

I'm develope some sensor with arduino primo, which use nrf52832 as a primary mcu. I want to measure battery voltage level,and i find some example like: devzone.nordicsemi.com/.../

but i confused with which SDK should i use? how do i check IC revisions? my arduino board's nrf52832 serial number is: n52832 QFAABO 1638CZ

Is that possible to use the same function using SAADC for battery measuring on arduino primo?

Or is there other solution to solve my problem by software?

Have a taken a look at this devzone post? Could also be useful to look at these three cases: case 1, case 2, case 3.

Yes, i had. but i want to do the function with software.... That seems have a lot difference from SDK, if i want to do it on arduino. For now i blocked at the board.h if i try to use the example
devzone.nordicsemi.com/.../ which i don't figure out how to define the arduino primo... Looking for more suggests.. Maybe arduino primo can't not use SAADC?

I think i have to modify the lib into the version without board.h ,The Pin define should be defined by arduino somewhere?

You could try looking at this example using an Arduino Uno. In addition, this tutorial might also be helpful. This same question was also asked in the Arduino forum.

Thanks for your suggestion but i think this issue not solve yet ,my purpose is do this job without any other component. In the considerations of efficiency and cost.
