What Are Embedded Systems?

In layman’s terms, an embedded system is a microprocessor or microcontroller-based combination of computer hardware and software designed for performing specific tasks and is usually a part of a much larger mechanical, electrical or electronic system.


Embedded systems can function independently as well. They are designed to work with limited human intervention.


Based on performance efficiency and functional requirements, embedded systems can be broadly categorized into four different types. Namely,

  1. Real-Time Embedded Systems
  2. Stand Alone Embedded Systems
  3. Networked Embedded Systems
  4. Mobile Embedded Systems


Because of their low power consumption, highly stable and reliable nature, and inexpensive characteristics, embedded systems have gained massive popularity and are used widely in various industries.


By now, you are probably wondering, ‘how can I learn embedded systems effectively?” Keep your eyes glued to this article and continue reading to find out! Let’s start with a few examples of Embedded Systems.


Examples of embedded systems

Some common examples of Embedded Systems are:

  • Traffic Control System
  • ATM
  • Calculators
  • Microwave Ovens
  • MP3 music players
  • Card Swipe Machine
  • Digital Cameras
  • Mobile Phones
  • Televisions
  • Washing Machine
  • Medical equipment and so on.


If you are a student who is wondering how to start learning embedded systems, then you have come across the appropriate article.


In this article, we will provide you with a roadmap to learning embedded systems from scratch to a professional level and also tell you about the important prerequisites before learning embedded systems.

Do Embedded Systems Need Coding?

Yes, all embedded systems need to be coded for them to perform the desired functions. Various programming languages like Embedded C, Embedded C++, Embedded Python, and Embedded Java are used to program embedded systems among which the most commonly used programming languages are Embedded C and Embedded C++.
You can train yourself to learn C++ and Python with us here.

How To Start Learning Embedded Systems?

  • Know the basics of electronics – Knowing the basics of electronics, especially subjects like basic electrical, electronic devices, control systems, and circuit theory is crucial before jumping into embedded systems.

    Learners who are directly opting to learn embedded systems before having the foundational knowledge of electronics will not be able to fully understand the ‘why(s)’ and the ‘what(s)’ of the subject.


    They will face difficulty in designing circuits, linking components, and figuring out which electronic device is to be used in a particular embedded system design. Knowledge of computer hardware is also good to have before learning Embedded Systems.


  • Understand the basic structure of an embedded system – It is needless to say that if someone is learning Embedded Systems then one should definitely, first and foremost be aware of the basic structure of an embedded system. An embedded system consists of 3 parts –
    1) The software,
    2) The hardware and
    3) The firmware.
    Students need to know which component goes where and what is the functionality or requirement of each of the components.


  • Know the programming languages – Another important prerequisite when learning embedded systems is knowing at least one coding language. Before knowing how to learn embedded systems programming, students must take up a normal coding language and master it.

    Most of the students, who take up embedded systems as their field of study, come from an engineering or science background. Therefore, most of them can code in languages like C, C++, Java, and Python. Embedded C, Embedded C++, Embedded Java, and Embedded Python are just extensions of these common coding languages.


    Hence, coders and engineers can easily learn embedded system programming to develop their own embedded systems.


  • Choose a board/embedded computer – Selecting an appropriate board or embedded computer to work on is a tough nut to crack, especially for beginners. Development boards combine a processors and chips with specific memory.

    There are a few considerations for development board like the use of bus type, memory, processor type, and operating system etc. There are several factors involved in choosing an embedded computer or board. Like your memory requirements, the speed of the system, power consumption of the system, and on-chip peripherals.


    It is important to choose a computer or board to figure out how to learn embedded software development by yourself. There are several boards and computers available in the market today.


    One should conduct thorough online research before settling upon a particular embedded board or computer because it is a costly and one-time investment.


  • Microcontroller know-how – An important prerequisite to learning embedded systems is knowing how microcontrollers work and where they are used. A microcontroller is installed in systems to control a single type of function.

    One needs to understand how a microcontroller utilizes RAM and ROM and how to program a microcontroller if one wants to successfully learn embedded systems. Microcontroller know-how goes a long way in making one understand embedded systems better.


  • Select tools and gather the supplies – You will want to have your equipment like tools and other supplies if you are aiming to become a full-fledged embedded systems engineer so that you can practice and experiment with developing embedded systems.

    You can select these tools and supplies after conducting research online or by taking advice from a mentor.


    Some tools necessary to develop an embedded system are Editor, Assembler, Compiler, Debugger, Linker, Emulator, and IDE. Some of the most common software development kits are PyCharm, Webstorm, QT Creator, MPLAB X, NetBeans, Eclipse, and Visual Studio.


    You need to install one of these software on your embedded personal computer to compile your codes.


  • Develop a mini project for practice – Once you have figured out how to learn embedded software development and are done setting up the necessary tools and software required to build a project, you can go on to develop your embedded system. Start small.

    Choose a common project which has a lot of resources available online like a fire alarm or a calculator. Apply your theoretical knowledge and try to implement all that you have learned about embedded systems before trying to take help from the online resources.


    This way, you get to learn by yourself and test your knowledge of embedded systems to see where you stand. It is typical to first be unable to fully construct an embedded system by yourself.


    Don’t panic and try different avenues through which you can learn more and clear your doubts about the project that you are building. Learn from your past mistakes and soon you’ll be able to build your embedded system.


  • Troubleshoot and improve – The most effective way to learn embedded systems is through the trial and error method. Oftentimes, learners cannot accurately gauge the system requirements and utility of certain components. There might also be a small defect in the electronic circuit like an unintended short circuit or open circuit.

    The program code might have a logical error and so on. The only way to correct these mistakes is to troubleshoot, that is, to debug and make sure you are constantly improving and optimizing your code as well as the hardware.


    It is quite difficult even for experienced professionals to accurately build an embedded system in the first few attempts. It is only through trial and testing that one can guarantee that a particular embedded system works properly.


How To Learn Embedded Systems From Basics?
