Hi,
I’m trying to read internal temperature sensor on ADC1, but the ADC result is always 4095.
I use STM32L471, and I know that the problem is not HW related, when I run a different bin it reads the temp ok.
Tried to read VREFINT, raw value is also 4095.
Attached below screenshots with clock tree configuration and code.
p.s. also tested with different clock speeds and sample cycles with no luck.
