This complete beginner’s guide takes you from zero experience to confidently programming embedded systems in C. You’ll begin with an introduction to embedded C programming, exploring how embedded systems work, how to choose the right processor and programming language, and the overall software development process for microcontrollers. These first lessons build a solid conceptual foundation before you start coding.

You’ll then dive into the 8051 microcontroller family, one of the most widely used architectures in embedded systems. Lessons cover external interfaces, clock frequencies, performance considerations, memory architecture, interrupt handling and power consumption, giving you an understanding of how hardware and software interact in real-world devices.

The course guides you through writing your first embedded C program—your own “Hello Embedded World”—while dissecting its structure and introducing you to bit variables. You’ll learn how to read input from switches, write and read bits with clear code examples, and structure your embedded C codebase with project and port header files.

As you progress, you’ll master meeting real-time constraints using hardware timers, implementing hardware timeouts, and understanding timer registers. You’ll design and build a simple embedded operating system (sEOS), explore task scheduling and stopping, and compare alternative embedded system architectures to choose the best approach for your project.

Advanced sections cover designing multi-state systems with traffic light sequencing examples, using the serial interface for RS-232 communication with on-chip UART, and managing memory requirements for serial data transmission. A practical case study shows you how to build an intruder alarm system, reinforcing your learning with a real-world application. The course concludes with guidance on advanced patterns and time-triggered embedded systems design so you know where to go next on your embedded programming journey.
