TM32 SRAM Stack Allocation & Deallocation Explained | C for Embedded System

In this video, we break down how stack allocation and deallocation actually work inside the SRAM of an STM32 microcontroller (STM32F411). Understand how the Stack Pointer (SP) moves during function calls, what happens when a function returns, and whether local variables are truly erased or just waiting to be overwritten in memory. 👨‍🏫 Meet Your Instructor – Yashwanth Kumar VG Yashwanth Kumar | NIT Trichy Graduate | 2 Years of Experience at Texas Instruments (TI) Learn C Programming for Embedded Systems with Yashwanth Kumar, a graduate of the National Institute of Technology, Tiruchirappalli (NIT Trichy), with 2 years of professional experience at Texas Instruments.
