Static variables in C are one of the most misunderstood topics in embedded systems programming. In this video course, you will fully understand static variables in Embedded C by combining clear theory, visual slides, and a real STM32 microcontroller project that demonstrates exactly how static variables behave in memory and during program execution.
This tutorial explains what static variables are, how to declare them, and why static local and static global variables behave differently in C. You’ll learn how scope, lifetime, and visibility change when the static keyword is used — and how this directly impacts embedded firmware design, memory usage, and code safety.
Unlike generic C tutorials, this course uses a hands-on embedded project running on an STM32 microcontroller to prove every concept. You will see real code, debug output, and runtime behavior, not just theory.
What you’ll learn in this video:
What static variables are in C and why they exist
How to declare static variables (local and global)
Static local vs static global variables — key differences
Static variables vs normal C variables (automatic & global)
How visibility and scope change with static
Why static variables keep their value between function calls
Practical Embedded Project (STM32)
This video includes:
A real embedded C project
Code compiled and run on an STM32 microcontroller
Debug sessions showing variable lifetime & memory behavior
Examples that demonstrate static behavior across function calls
