Reading analog values from potentiometer through ADC in STM32F4 Discovery Board.

Hi, I am trying to read the analog values from potentiometer which is connected ADC channel 0, namely pin PA0 in my development board. I have attached the related part of the code. I got all of these registers' values from reference manual. I watched many videos and read articles and wrote this code, but there is an issue. The values that I get (I display them on LCD) are random and don't depend on the rotation of the potentiometer. PA0 behaves like if it is not connected to the...
