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 .

Configure pin as an INPUT

What STM32 part?
