What happens when GPIO is sourcing more mA than allowed?

My STM32F746 can source 25 mA per pin, but only 120 mA in total.What happens if we exceed that amount? Will there be a brown out, will the STM32 reset, or will the STM32 get damaged?

STM32H753 writing option bytes stalls execution

Hi,We are using an STM32H753 (revision V) and using the bank swap functionality to implement a firmware update system. To do this we need to write to the option bytes to toggle the bank swap bit.This process works but we have noticed that when the cu...

Hi, I have a brend new STM32L652 with tehe latest CubeIDE. When I try to program the MCU, the program seams to be loaded to the MCU but unfortunately I cannot debug it like I use to for other boards like NUCLEO. Do I have to configure something ? TY

Does remap of CAN1 pins work on STM32-E407?

I bought a few Olimex STM32-E407 boards lately. I need to use the CAN1 bus. However, the default PA11, and PA12 have not populated, and I remapped to PD0 and PD1. The code always failed immediately at CAN_init (generated by STM32CubeMX). No choice, I...
