Big Endianness vs Little Endianness

EmbeddedWala Aug 22, 2024 0 764

Little-Endian: Stores the least significant byte (LSB) first at the lowest memory address. For example, 0x12345678 is stored as 78 56 34 12. This format is common in x86 architectures. Big-Endian: Stores the most significant byte (MSB) first at the ...

What is Endianness?

EmbeddedWala Aug 22, 2024 0 458

Endianness is a term used to describe the order in which a sequence of bytes is arranged into larger numerical values when stored in computer memory. Specifically, it determines how multi-byte data types (such as integers or floating-point numbers) a...

Volatile Keyword In C

EmbeddedWala Aug 18, 2024 0 1.1K

The volatile keyword in C is used to inform the compiler that a variable's value may change at any time, without any action being taken by the code in which it appears. This is crucial when working with hardware registers, memory-mapped I/O, or varia...

Memory Layout of C Program

EmbeddedWala Jul 11, 2023 1 4.8K

The memory layout in C programming is a fundamental concept that is crucial for understanding how memory is managed during program execution. It defines the organization and structure of memory that the C programming language uses. In this blog post,...

Inline Function in C

EmbeddedWala Jul 8, 2023 0 4.0K

Inline functions play a crucial role in C/C++ programming, offering enhanced performance by minimizing the burden of function calls. Unlike standard functions, inline functions are expanded at the exact location where they are invoked, leading to acc...

Understanding Buffer Overflow and Stack Smashing

EmbeddedWala May 11, 2023 0 2.7K

Buffer overflow and stack smashing are two types of vulnerabilities that can be exploited by hackers to compromise a computer system. These attacks occur when an attacker can write data beyond the intended boundaries of a buffer, resulting in a viola...

How To Write The Clean Code

EmbeddedWala May 5, 2023 0 1.7K

Developing clean code is crucial for the success of any software project. Clean code makes it easy to read, understand, maintain, and debug. It also enables effective collaboration between developers, reducing confusion and misunderstandings. Writing...

Dynamic Memory Allocation in C

EmbeddedWala May 5, 2023 0 2.8K

Dynamic memory allocation in C is the process of allocating memory during runtime, rather than at compile-time, which is known as static memory allocation. Unlike static memory allocation, dynamic memory allocation enables programs to allocate memory...

C/C++ Pre-Processor Directives

EmbeddedWala Apr 30, 2023 0 2.5K

The C programming language offers developers a robust set of features and tools that empower them to optimize and customize their code. Among these tools, preprocessor directives stand out as a powerful mechanism for making decisions and modifying co...

Introduction to State Machines in C : Embedded Systems

EmbeddedWala Apr 18, 2023 0 7.2K

A state machine is a model used to represent the behavior of a system, which can be a software system, an electronic system, or any other type of system. It is composed of a set of states, each representing a specific condition or mode of the system,...

Understanding Storage Classes in C: A Beginner's Guide

EmbeddedWala Apr 12, 2023 0 3.9K

Storage classes in C are used to specify the lifetime, visibility, and scope of variables in a C program. They define how and where a variable is stored, and how it can be accessed by the program. There are four different storage classes in C: auto,...
