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
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,
This post explains how to drive a common cathode seven-segment display (SSD) with the PIC18F45Q10 microcontroller. We’ll implement a hexadecimal counter (0-F) that cycles through each digit, showcasing how to manipulate output pins to control the display. What is a Seven-Segment Display (SSD)? A Seven-Segment Display (SSD) is an electronic display device widely used for
In this blog post, we’ll explore how to interface a simple LED with the PIC18F45Q10 microcontroller and make it blink at regular intervals. This is a great beginner project to understand how to work with input/output (I/O) pins, configure the microcontroller, and implement a delay for controlling time-based events.

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
