# Embedded Systems Engineering Roadmap

This roadmap is designed to assist beginners aspiring to build a career as an Embedded Engineer / Developer. To provide comprehensive guidance, I have carefully selected the topics based on current open job requirements and organized them according to my personal experience.

Becoming an embedded engineer requires a broad understanding of both software and hardware. If you are starting on this journey, you must be highly motivated and passionate to pursue this path. The field of embedded systems demands a solid understanding of hardware functionality. But, as the well-known saying goes, "Hardware is hard!". So, patience and passion are the essential qualities that will help you overcome the various challenges encountered along this journey.

## What is an Embedded System?

An [***embedded system***](https://www.analog.com/en/design-center/glossary/embedded-system.html) 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.

#### 🕹️ 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 only for learning purposes and are not are not optimized to be used in industry. Additionally, the Arduino takes care of most of the low-level operations and manipulation of registers that you, as an embedded engineer, should be able to handle yourself. If you want to become a professional embedded developer, you must be able to effectively use industry-standard APIs and frameworks provided and approved by microcontroller vendors. For example, CMSIS for ARM Cortex, STM32Cube for STM32, ESP-IDF for Espressif microcontrollers, etc.

## History

The idea of creating this roadmap came from [vazeri / Embedded-Engineering-RoadMap-2018](https://github.com/vazeri/Embedded-Engineering-RoadMap-2018) which was well designed but had some flaws and not updated for years.
I took that idea, changed the structure of the roadmap and tried to improve it. The initial results can be accessed in [m3y54m / Embedded-Engineering-Roadmap-Archived](https://github.com/m3y54m/Embedded-Engineering-Roadmap-Archived) which is now archived. Early versions of the roadmap were created using [Balsamiq Wireframes](https://balsamiq.com) which is not suitable for these types of diagrams. So I decided to use Microsoft Visio instead and redrew the whole diagram.

Special thanks to my friends in the community of Iranian Embedded Engineers in Twitter and [r/embedded](https://www.reddit.com/r/embedded) subreddit for their suggestions that helped in improving this roadmap.

## Contribution

If you think that this roadmap can be improved in anyway or you know some good learning resources that can be added here, please start an issue or a pull request. I’ll be maintaining and updating this repository frequently.

The source file is created using [Microsoft Visio](https://office.com/visio) in `.vsdx` format and included in this repository for your contributions.
