  1. Introduction to Embedded Engineering Embedded engineering combines hardware and software to create intelligent devices. These devices can be found everywhere, from smartphones and cars to medical equipment and industrial machinery.

  2. Hardware Design Principles Microcontrollers Sensors 1 2 The brain of embedded systems, they execute instructions and control devices. Gather data about the environment, providing input to the microcontroller. Actuators Power Supply 3 4 React to commands from the microcontroller, controlling physical elements. Provides energy to operate the system, often using batteries or external sources.

  3. Microcontroller Architecture Central Processing Unit (CPU) Memory Peripherals Executes instructions and performs calculations. Stores data and instructions. Interface with the outside world. • Program Memory (ROM/Flash) • Timers • Arithmetic Logic Unit (ALU) • Data Memory (RAM) • Serial Communication (UART, SPI) • Control Unit • Analog to Digital Converters (ADC)

  4. Embedded Software Development 1 2 3 4 Requirements Analysis Software Design Coding and Testing Deployment Develop a software architecture and choose programming languages. Write code, test, and debug to ensure functionality. Install the software on the microcontroller and configure settings. Define the system's functionalities and constraints.

  5. Real-Time Operating Systems Task Scheduling Inter-task Communication RTOS manage and prioritize tasks to ensure efficient execution. Allow tasks to share data and synchronize their actions. Resource Management Time Management Control access to shared resources, such as memory and peripherals. Provide precise timing for critical tasks, ensuring real-time performance.

  6. Debugging and Testing Techniques Hardware Debugging Software Debugging Simulation and Emulation Functional Testing Use tools like oscilloscopes and logic analyzers to analyze signals. Employ breakpoints, logging, and tracing techniques to identify errors. Verify system functionality against defined requirements. Test software behavior without needing physical hardware.

  7. Trends and Future Directions in Embedded Systems Internet of Things (IoT) Artificial Intelligence (AI) Connecting devices to the internet for data sharing and remote control. Integrating AI algorithms into embedded systems for decision-making. Cloud Computing Cybersecurity Offloading processing and storage to cloud services for scalability and flexibility. Protecting embedded systems from malicious attacks and data breaches.
