In the previous article, we implemented a button-controlled LED toggle using a polling method. While simple and effective for basic projects, polling is inefficient for real-time or low-power embedded systems. In this article, we will improve the design by configuring the button press to trigger an external interrupt (EXTI) instead of continuously polling the button
In this article, we will walk through setting up a simple project on the STM32F446RE Nucleo-64 board where a user button press toggles an onboard LED. The focus will be on manual HAL configuration without relying on interrupts, using a pure polling method. This exercise covers basic GPIO initialization, clock setup, and handling a simple
When you’re getting started with STM32 microcontrollers, one of the best ways to dive in is by building a simple LED Blinky project. In this post, I’ll walk you through every step to create a new STM32CubeIDE project for the Nucleo-F446RE board, manually write the initialization code using STM32 HAL APIs, and explain some important

This beginner-friendly course is designed for students and aspiring programmers who want to learn C programming by doing. Instead of long lectures and dry theory, you’ll write real code from Day 1. Every lesson is hands-on, built with short instructions, real examples, and instant challenges — just like how you’d learn in a coding bootcamp
