Module 12: Embedded Systems Programming

Overview

Embedded systems programming is a specialized area of C development focused on creating software for dedicated computer systems that perform specific functions within larger mechanical or electrical systems. This module covers the unique challenges and techniques involved in programming for resource-constrained environments, real-time requirements, and direct hardware interaction.

Learning Objectives

By the end of this module, you should be able to: - Understand the fundamentals of embedded systems and their constraints - Program at the hardware level with direct memory-mapped I/O - Implement real-time programming techniques and scheduling - Work with embedded C extensions and specialized compilers - Interface with various hardware components and sensors - Debug and optimize code for embedded environments - Understand power management and resource optimization
