STM32G431KB: I try to make a PWM signal out of my TIM1 channel. I followed this tutorial: https://controllerstech.com/pwm-in-stm32/ My PWM signal goes from 1V to 4.3V and not from 0 to 3.3V. How is this possible?

Take your pick:

The ground you're measuring from isn't at the same potential as the MCU.

Scope is horribly uncalibrated.

Channel offset was not interpreted correctly, or other user reading error.
