STM32F103RBT6 GPIO Interrupt

Posted on May 11, 2017 at 09:19

Hello,

I've designed my project using STM32F103RBT6. I've connected two switches to PC10 and PA10.

Now I need external interrupt on both the swithes, but using cubeMX I'm able to set external interrupt to only one of the switches.

How can I set external interrupt to two switches PC10 and PA10 ??

Thank you

hi, if I understood correctly.

There is nothing to do with the cubeMX,

You simply cannot do that.

External Interrupt can only work as followed:(from

)

p.209

As for registers, you may check AFIO_EXTICRx registers in 9.4.3

So, PC10 and

PA10

can only be the trigger source of EXTI10 exclusively.

Good Luck!
