Simple change of existing code for STM32 processor

I am newcomer to STM32, and I have to troubleshoot an existing STM32 project. I need help to fix 2 issues:

1. There are two adc channels, one of the brings correct data, the other one not. I think it is a question of configuration, but need help to find the reason for the issue.

2. This is a low-power design, where a timer interrupts every 0.25s to wake up from sleep mode and check the inputs. TIM2 is used for this purpose, but STM32 uses to much power in sleep mode.

So, I need to use STOP mode instead where current consumption is very low. For this I need to use the RTC clock for the interrupts every 0.25s, because then current is really low and also RTC is the only timer that can wake up from STOP mode.

The project is to fix issue 1 , and implement the RTC timer function described in 2.

There is on short notice also a larger extension to the project that may be awarded to the freelancer that can fix this.
