STM32 Callbacks: Where Most Developers Go Wrong
Master STM32 Interrupts without Crashing Your Board!
In Part 4 of our STM32 Beginner Series, we're ditching the "polling" method and leveling up to Interrupts! If you've ever wondered how to make your button presses responsive without freezing your main loop, this tutorial is exactly what you need. We’ll walk through CubeMX setup and show you the right way to handle callbacks so your code stays fast and clean.
In this video, you will learn:
CubeMX Setup: How to configure GPIO inputs as External Interrupts (EXTI) in seconds.
Callback Magic: Where to find the callback functions in the code (and where to put them!).
The Golden Rule: Why we only set "flags" inside interrupts to keep our main loop running smoothly.
Live Demo: testing it all on a Nucleo board (works with any STM32!).

Hardware used: Nucleo-C031C6 (Compatible with any STM32 Eval board)
