1. Embedded Systems

Embedded systems are a ubiquitous component of our everyday lives.

  • An embedded system is a system that performs a specific task and has a computer embedded inside. A system is comprised of components and interfaces connected together for a common purpose.
  • An embedded system is a microcomputer with mechanical, chemical, or electrical devices attached to it, programmed for a specific dedicated purpose, and packaged up as a complete system.

  • Embedded Systems
    • physical world
    • limited resources
    • limited context
  • The Internet (IoT)
    • Cyber world
    • Unlimited resources
    • rich context

2. Internet of Things (IoT)

  • But, the Internet part of IoT will not be covered in this class.

3. Microcontroller (MCU/CPU)

  • Microcontrollers have basic computing functionality

  • Many onboard I/O subsystems

    • General Purpose IO (GPIO)
    • A/D and D/A
    • Interrupts
    • Clocks/Timers
    • Buses

  • Every pin maps to one or more subsystems

4. Prerequisites

  • circuit theory

  • digital logic theory

  • programming skills

  • signal processing and control

But do not worry !!! I will build this class while assuming students having no prior knowledge above

5. What can We Do After Taking this Class?
