In my project one of STM32H7 ADC channels is used to measure the device current. I'm using STOP mode with periodic (10 ms) wakeups to lower the power consumption. Is it possible to use the ADC channel to measure the current during STOP mode?

I dont have experience with stm32h, but it looks like when you enter STOP mode you stall the peripheral clock and the peripheral bus clock. So just by looking at the AN5215 id say no is not possible the use the ADC if its clock source is not working.

we dont need to firmware by ourselves, lets talk
