What you'll learn:
- 1. Write clean, correct C programs from scratch — and understand exactly what happens in memory when they run
- 2. Master pointers step by step — pass by reference, pointer types, and how they map to hardware
- 3. Pack, unpack, and manipulate data at the bit level using masks, shifts, and bitwise operators
- 4. Model real-world hardware data with arrays, structures, and unions — and know their exact memory layout
- 5. Convert fluently between binary, hex, and decimal — the number systems embedded engineers use daily
- 6. Use the C preprocessor properly: #define macros, macros with arguments, and conditional compilation
- 7. Explain the complete compilation pipeline — what the compiler, assembler, and linker each do to your code
- 8. Choose the right data types and variables for memory-constrained embedded targets
- 9. Build the exact C foundation needed for microcontroller work: GPIO, UART, and interrupts come next
The C programming language is the foundation of every embedded systems role in the world. If you want to write firmware, understand how microcontrollers work, or break into embedded systems — this is the one skill you cannot skip.
This course teaches C the way it is actually used in embedded development: hands-on, visual, and with real code written in front of you. Every section follows a simple pattern — theory first, then a working program that proves it. No filler, no fluff.
Who this course is for: Whether you are a fresh engineering graduate, a hobbyist who has outgrown Arduino, or a software developer pivoting into embedded systems — this course was built for you. No prior embedded experience required. A basic comfort with computers is enough to begin.
What you will learn:
How data is stored in memory — RAM, addresses, binary, and hex — the foundation everything else builds on
C fundamentals: data types, variables, control flow, functions, and loops with live coding throughout
Pointers and memory — the most important (and feared) topic in C, explained visually and step by step
Arrays and structures — how to model real-world hardware data in C
The Embedded C essentials: volatile, bitwise operators, bit manipulation, and preprocessor directives
The complete C compilation pipeline — from source code to machine code, including what a linker actually does
How the course works: Every section builds on the last. We start with what an embedded system is and end with the compilation process that turns your C file into the binary that runs on a chip. Along the way, every concept gets a working program. You will spend more time reading and writing code than reading slides.
Any C compiler or IDE works — the course shows a free setup, and every example runs on plain gcc as well.
Free companion articles for every section are linked inside each lecture's resources.
By the end of this course, you will:
Write clean, correct C programs from scratch
Understand how your code maps to memory and hardware
Read and use datasheets that reference registers, bit fields, and memory maps
Be fully prepared to move into a microcontroller-specific course with confidence
Updated based on learner feedback. Suitable for students and working professionals alike.
