2. How to configure an external interrupt EXTI with STM32

Описание: In this tutorial I will show you how to quickly configure your stm32 microcontroller to handle an external interrupt and return to the main process afterwards.
This is a hardware interrupt implementation of the powerful ARM controller chip.
In this example the interrupt is caused by a push button press and a callback funtion is implemented to service the interrupt.

In this tutorial, you will learn how to configure an external interrupt (EXTI) on an STM32 microcontroller using STM32CubeIDE. External interrupts allow your microcontroller to react to external events, making them essential for responsive and efficient embedded systems. Follow this step-by-step guide to set up and handle EXTI, enhancing your STM32 project’s capabilities.

Introduction to External Interrupts (EXTI)
Configuring GPIO pins for EXTI in STM32CubeIDE
Setting up interrupt priorities and handling
Writing the interrupt service routine (ISR)
Testing and debugging EXTI configuration
