Introduction

Embedded systems are the foundation of modern technology, and the programming language used to develop these systems is Embedded C. This programming language is designed to be used in microcontrollers, which are essentially small computers that control and automate various tasks in electronic devices.

In this article, we will explore Embedded C in detail, its features, advantages, disadvantages, and applications in the embedded system.

What is Embedded C?

Embedded C is a variant of the C programming language. It is used to develop embedded systems, which are computer systems that have a dedicated function within a larger mechanical or electrical system. Embedded systems are designed to perform specific tasks, and they have real-time constraints.

The programming language used in embedded systems should be low-level, efficient, and capable of communicating directly with the hardware. Embedded C meets these requirements and provides a simple, yet powerful, programming language for developing embedded systems.
