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
In this post, I will explain how to connect a PIC18F45Q10 microcontroller to a PC terminal using a PL2303 USB to TTL converter.The idea is simple: blink an LED to confirm the microcontroller is running, and print “Hello World” continuously over UART to the terminal. Along the way, I also faced a few practical issues,

Embedded systems rely on efficient low-level programming to interact directly with hardware. In this course, you will learn how to write practical Embedded C programs used in real microcontroller-based systems. Rather than focusing only on theory, this course follows a practice-driven approach. Each lesson includes hands-on coding exercises that simulate real firmware development tasks used
