In embedded systems, GPIO registers are often used to control individual pins of a microcontroller. While registers can always be accessed using integer masks and shifts, another method sometimes used is the C bit-field feature. A bit-field is a property of structures that allows mapping individual bits of a word. This can be convenient for

The LED blinking program is the “Hello World” of any Microcontroller. If you are just starting with the 8051 microcontrollers, this is the best first project to understand how GPIO pins work, how to configure them as output, and how to control hardware using C code. In this tutorial, we will cover how to interface

Bit manipulation is one of the most powerful concepts in C programming, C++ programming, and embedded systems development. It allows you to directly access and modify individual bits inside an integer, making it extremely useful for hardware register control, memory optimization, cryptography, networking, and performance-critical applications. Instead of working on an entire integer, bit manipulation

Operators are the backbone of any programming language. So C/C++ programming language is incomplete without the operators. The C/C++ programming language support mainly three types of operators unary operators, binary operators, and ternary operator (Conditional-expression operator). Operators in C/C++ programming gives the direction to the compiler to perform the specific task. C language

The Hypertext Transfer Protocol (HTTP) is a stateless application layer protocol for distributed, collaborative, hypermedia information systems. In this article, I will explain, how you can create an HTTP get post request in C without using the library. But before going to create get post request let understand the what is Http protocol in a

We use XML to carry data between server and client. XML simplifies the data transportation and carry data in plain text format which is readable by both human and machine. It is the biggest reason to provide a software and hardware independent way of transporting, storing, and sharing data. This feature of XML gives the
