How and Where to know Which pins can be used to GPIOs InterruptIn at the same time, to take NUCLEO-F429ZI board.
Try reference manual for the chip family, RM0090, 12.2.5. Top of my head, the rule seems to be that in PX.Y Y cannot be the same. Something like PA2 and PB3 can be used as InterruptIn at the same time, while PA4 and PC4 cannot.
