ADC value fail to be detected, STM32F401CE

[ALAN1014]

I had tried to simulate a temperature sensor in Proteus. However I found that the ADC input fail to be read by the MC. The ADC value remains as zero.

Your question is about a problem with the simulation software,

so better you ask Proteus/contact about what and why its behaving this way.

Does the circuit work in reality on an actual MCU?
If it does, then the simulator is wrong.
If it doesn't your program is wrong.
