hi.

i want to write code for EXTI in IAR with SPL library,but i dont know what do i do with spl.

 i realy need steps of the configration of EXTI setting.

who can say  the steps of EXTI to me??

do i need configration in gpio or do i set gpio pin to Alternate function??how can i understand what is function of interrupt routin in main.c and write my code in that routin block?

i can use EXTI in cube , but i want to understand stm how works in BASE .

There are typically EXTI examples under the SPL peripheral examples, look there

Configure pin as an INPUT

What STM32 part?
