Implementing External Interrupts (EXTI) on STM32 with Standard Peripheral Library
External interrupts allow a microcontroller to respond immediately too external events by pausing its current program execution, handling the interrupt request, and then resuming normal operation. The STM32 EXTI controller manages up to 20 interrupt/event lines, with GPIO pins 0-15 connected to EXTI lines 0-15. Additional lines serve specific p ...
