Hi,

I would like to know, if I can use a Boot pin of my STM32F103 how GPIO pin to monitor an EXTI event.

I have just used all other pin and I have necessity to use an additional external interrupt.

A Boot pin is a free pin used only for boot operation, but I don't know if I can program it for alternative function.

Best Regards

Valerio

BOOT0 is not available to you

BOOT1 can be used as PB2
