Hello all, I have encountered unexpected behavior on the voltage level of PC12 when I enable PB12.My setup:PC12: Level high, output mode PP, no PU no PD, Output speed High. PB12: Level low, output mode PP, no PU no PD, Output speed Low.Without PB12 t...

I use a STM32H723VGT6 as a master in a critical SPI communication with another microcontroller (critical because this mcu is very strict in the SPI timing, especially the time between CS and the start of CLK, and I cannot operate on the firmware of t...
