Hello, I´m trying to get a precise measure with the ADC of the NUCLEO-F103RB but I can´t get a stable result. I measure the internal reference voltage in IN17 of ADC1 but the value is also unstable, so I think there is where my problem is. I want to know the value of VREFINT_CAL to make the adjustment in the measure,but I could not find it in the reference manual or anywhere in the documentation.
