Dear STM32One,

Could you please help me?

As already explained to you on the Keil forum, this is clearly shown in the schematics!

(note that there are additional replies in that thread since your last post there)

I think I failed to explain my doubt.Yes, I have seen the responses at Keil.

From the schematics, I could understand that the pin PC4 in Extension connector is connected to the on-board pot RV1. I I was confused where to connect the variable power supply leads.Because I were able to see values changing for the ADCConvertedValue without connecting variable supply to PC4 and POT not being adjusted.Also when I tested the pins PC4 and GND with a multimeter with POT varying, the voltage goes to 0-3.26V.How then the external supply helps? I am novice to this kind of activity and am learning the basics of microcontrollers.
