Thank you. I am not so experienced as all you are. So I am a couple of years
behind... but beter late then never 😉
I recon I have to place some sort of voltage divider for the pins on the
QEncoder. This because i twill blow my MCU? Right?

I did that a long time ago. So have several others. See
$ find . -name "*qencoder*"
boards/arm/stm32/common/include/board_qencoder.h
boards/arm/stm32/common/src/stm32_qencoder.c
boards/arm/stm32l4/nucleo-l432kc/src/stm32_qencoder.c
boards/arm/stm32l4/nucleo-l476rg/src/stm32_qencoder.c
I don't see any defconfigs with the quadrature encoded enabled, however.
See also apps/examples/qencoder
