Description

Introduction: Embedded C Programming

Embedded C Programming is a specialized version of the C programming language that is tailored for embedded systems. It is used to develop software that directly interacts with the hardware of devices like microcontrollers, sensors, and actuators. This course is designed to teach participants the fundamentals of Embedded C and provide hands-on experience with writing and executing code for embedded applications. By the end of this training, participants will be equipped to develop and troubleshoot software for real-time embedded systems.

Prerequisites: Embedded C Programming

1. Basic knowledge of C programming: Familiarity with standard C programming concepts like data types, loops, and functions.
2. Basic understanding of electronics: Awareness of microcontroller components, circuits, and peripherals.
3. Optional: Prior experience with microcontrollers or embedded hardware (e.g., Arduino, STM32) will be helpful but is not mandatory.
