By dedicating enough time and effort practicing and doing projects you will soon find yourself as a real embedded engineer! 😀

❓ What is an Embedded System?

▶️ ISO/IEC/IEEE 24765 Standard:

computer system that is part of a larger system and performs some of the requirements of that system. For example, a computer system

used in an aircraft or rapid transit system.

The hardware and software of an embedded system are usually minimized and optimized for specific functions. The embedded system includes at least one microcontroller, microprocessor or digital signal processor. The embedded system designed to optimize reliability, cost, size and power saving for applications.

▶️ "Making Embedded Systems" Book:

An embedded system is a computerized system that is purpose built for its application.

▶️ "Computer Organization and Embedded Systems" Book:

A physical system that employs computer control for a specific purpose, rather than for general-purpose computation, is referred to as an embedded system.

▶️ Analog Devices Glossary:

An embedded system is a system in which the computer (generally a microcontroller or microprocessor) is included as an integral part of the system.

Often, the computer is relatively invisible to the user, without obvious applications, files, or operating systems. Examples of products with invisible embedded systems are the controller that runs a microwave oven or the engine control system of a modern automobile.

▶️ Embedded Systems Glossary:

A combination of computer hardware and software, and perhaps additional mechanical or other parts, designed to perform a dedicated function.

In some cases, embedded systems are part of a larger system or product, as in the case of an antilock braking system in a car.

Embedded Systems Engineering Roadmap</a>

The embedded systems engineering roadmap is structured into three fundamental areas: SOFTWARE, HARDWARE, and SOFT SKILLS. While the intersection of hardware and software is prevalent in embedded systems, specific job titles tend to emphasize one aspect over the other. For instance, roles like "Embedded Software Engineer/Developer," "Firmware Engineer/Developer," and "Embedded Linux Engineer/Developer" predominantly focus on software development. In contrast, positions such as "Embedded Hardware Engineer" and "Hardware Design Engineer" primarily deal with hardware design and electronics. Moreover, there are roles like "Embedded Systems Engineer" that necessitate a comprehensive understanding of both hardware and software. It's crucial to note that each company in the embedded industry may have unique requirements for a given job title. Therefore, it's essential to tailor your focus based on your career aspirations. If you're seeking an embedded software position, prioritize the software-related skills outlined in the roadmap. Conversely, if you're interested in an embedded hardware job, concentrate on hardware skills and dedicate more time to learning electronics. The roadmap provides a comprehensive guide to the essential topics for a typical "Embedded Systems Engineer" role. By delving into both software and hardware aspects, you can develop the necessary skills to thrive in this dynamic field. However, if you have a clear preference for software or hardware, you can tailor your learning path accordingly. 🔗 For more information about the history behind this roadmap, read this article: Embedded Systems Roadmap: Bridging the Gap

[!NOTE]

Remember that the importance of individual software and hardware skills can differ depending on the specific requirements of the company and the job role.

Both free and paid resources are included to provide a range of options, allowing you to choose what best suits your needs and preferences.

😕 Don't Know Where to Start!

If you feel overwhelmed by the extensive list of topics in the roadmap, you're not alone. Before delving too deeply, let's ease into it with some simple starter projects. Learning embedded systems engineering takes time and effort. Don't get discouraged if you don't understand something right away. Keep practicing and you will eventually get there.

⚒️ Projects

Engaging in hands-on projects is the most effective approach to learning. Rather than solely relying on theoretical knowledge from books or articles. Undertaking projects allows for practical learning experiences. Even a seemingly basic project has the potential to teach you more than hours of aimless reading. You can refer to books, articles, and courses when faced with difficulties in understanding the problems in real-world projects. Don't try to build a complex project right away. Start with small, manageable projects to get your feet wet.

🔎 Search and Ask!

Use search engines to find the answers to your questions.

If you can't find what you're looking for using search engines, AI chatbots can also provide assistance. Keep in mind that AI may provide incorrect answers in some cases. It's best to confirm any answers with more reliable references.

If you have reservations about relying on AI advice alone, you can also ask your questions from real people:

✳️ Career Development

As an embedded systems engineer, it's essential to stay up-to-date with industry trends, best practices, and new technologies to advance your career. Here are some resources to help you achieve your career goals:

🔗 EmbeddedJobs - A job board focused exclusively on Embedded Systems job market.

🎥 Courses and YouTube Contents

You may have heard that YouTube is a university. And it's true - there is an extensive amount of invaluable free content on embedded systems available on YouTube. You'll also find some excellent free courses through Coursera and EdX. Additionally, Udemy offers some high-quality paid course options.

🕹️ Arduino

If you do not have any background in programming embedded systems, Arduino boards and libraries are the best choice for you to start and learn the basics. Just keep in mind that most of the Arduino libraries are developed for learning purposes and are not optimized to be used in industry. Additionally, the Arduino Core (the platform-specific implementation of the hardware-independent ArduinoCore-API) takes care of most of the low-level hardware-associated operations that you, as an embedded engineer, should be able to handle yourself or at least have a clear understanding of. If you want to become a professional embedded developer, you should be able to effectively use industry-standard APIs and SDKs provided and approved by microcontroller vendors, such as CMSIS for ARM Cortex-M microcontrollers, STM32Cube for STM32, ESP-IDF for Espressif microcontrollers, etc.
