Hello, I am trying to execute a simple ADC program(12bit) in stm32mp157c using trimpot with 10K as input in cube ide. Where output changes only at the voltage level of 3.2v

[ASuha.1]

While changing the value at the trimpot output values is constant(4095) and has no change as soon as when it reaches 3.2V it goes to zero. I am seeing output using uart.

​

Please assist me how to rectify it.​
