how to configure the adc internal reference voltage??

Hi team,

I am using STM32L052K8U6 package in my design. I need to configure the internal reference voltage instead of external reference voltage for ADC. Can i get any example program for same.

VREF for the ADC is always VREF or VDD(A) if there is no VREF pin. However you can measure VREF internal with the ADC and the scale the other measured voltages.

Hi,

In my 32 pin device don't have VREF pin and I need to use my internal reference voltage 1.22V as my ADC reference.
