STM32 Port Interrupt
Posted: Wed Nov 27, 2019 8:46 am
Hi everyone
I have connected a tactile switch at port PB11, which is active low.
I try to enable an interrupt on this port.
I can't see a particular selection of pin PB11.
The port B includes 15 I/O pins and FC7 offers port interrupt only for pins EXTI0, EXTI1, EXTI2, EXTI3, EXTI4, EXTI8, and EXTI13.
Why there is not included the EXTI11? Provided that the PB11 is an I/O port?
Is there any restriction for the rest pins of port B?
Thanks
