Hi, I'm experimenting with interrupts from port pins, I can make the basic example work. What I was trying to do is to create and EXTI interrupt from GPIOA bit 0 and also GPIOB bit 0, but I'm starting to think that this is not possible, when I set it up for GPIOB I lose the interrupt from GPIOA. So, is it possible, and if it is, is there a code example somewhere?

Thanks
