Posted on November 21, 2017 at 20:47Hello!
I want to calculate battery voltage, that connected to STM32L476RG board.
I've connected ADC pin and this battery with divider (so Vbattery<Vref.adc).
But I need to know how to get some factors/parameters.
See formula here:

(p.578)
And please tell me, where and how to get: VREFINT_CAL, VREFINT_DATA. And what does these parameters mean?
Thank you very much for your attention!
