This course is a complete, practical guide to Heap memory in Embedded C programming, designed specifically for microcontroller-based systems such as STM32.
If you want to understand how heap works internally, when to use it, when to avoid it, and how dynamic memory behaves on real embedded hardware, this course is for you.
What You Will Learn
In this course, you will learn:
✅ What is Heap memory and how it works as a data structure
✅ Difference between Heap vs Stack in embedded systems
✅ Dynamic memory allocation concepts in C programming
✅ How heap memory grows and how fragmentation occurs
✅ Detailed explanation of standard C heap APIs:
malloc()
calloc()
realloc()
free()
✅ Pros and cons of using heap in embedded systems
✅ Common heap-related bugs (memory leaks, fragmentation, corruption)
✅ Best practices for using heap safely on microcontrollers
Hands-On STM32 Embedded Project:
This course is not theory only.
You will work on a real STM32 embedded project where we:
Allocate heap memory on an STM32 microcontroller
Track how heap space grows at runtime
Observe memory usage directly on the embedded device
Understand how heap interacts with stack and global memory
Debug heap behavior step-by-step using Keil uVision
🔍 Live debugging with Keil:
Inspect heap pointers
Watch memory allocation in real time
Identify common mistakes that cause crashes and HardFaults
🎯 Who This Course Is For:
✔ Embedded Systems Engineers
✔ STM32 Developers
✔ C Programmers moving into Embedded Systems
✔ Students learning Embedded C & Memory Management
✔ Anyone confused about malloc() on microcontrollers
No operating system knowledge required — this course focuses on bare-metal embedded systems.
Why This Course Is Different:
Unlike desktop C programming, heap usage in embedded systems is very different and more dangerous if misunderstood.
This course explains:
Why heap is risky on microcontrollers
When heap is actually useful
How professionals manage heap in real embedded products
All concepts are explained using:
Simple diagrams
Clear explanations
Real STM32 code
Debugging sessions in Keil
