LPTIM count error on STM32L476RG

Hello,I am experiencing counting errors (specifically overflow counting errors) on LPTIM1.A bit of context first: the goal is to use the LPTIM1 to count pulses which are first treated by the COMP1 (to convert the input signal into an all-or-nothing s...

SPI1 and I2C1 pins are conflicting in the STM32H563

Hi Team, I am trying to use the SPI1 and the I2C1 simultaneously in the STM32H563ZI. Upon configuring the relevant pins in via cubeMX, I see that there is a conflict with the PB5 Pin. I want the PB5 to act as an SPI pin, whereas configuring I2C1 does...
