How to properly configure ADC injected group?

[EWarzocha]

Hello, I've tried to use ADC for two Potentiometers only with injected group conversion but couldn't make it work. I'm using STM32F446RE. I couldn't find solution so I'm asking here.

Previously I read their value correctly via polling and I know that rest of my code is working (there is not much else there, all the code related to ADC is below).

Am I missing something or the order of code is incorrect? The print in interrupt prints zeroes so the interrupt itself runs.

I'm using prescaler because APB2 clock is set to 90 Mhz and prescaler solved issues with reading interference.

Thanks in advance.
