 # 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.
+This roadmap is designed to assist beginners aspiring to build a career as an Embedded Engineer / Developer. To provide comprehensive guidance, the topics have been carefully selected based on current job requirements and organized 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.
+[ISO/IEC/IEEE 24765 Standard:](https://www.iso.org/obp/ui/en/#iso:std:iso-iec-ieee:24765:ed-2:v1:en)
 
-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.
+> **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:](https://www.oreilly.com/library/view/making-embedded-systems/9781449308889/)

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

-#### 🕹️ 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.

-#### 🐜 PlatformIO
+##### PlatformIO
 
 PlatformIO is a cross-platform, cross-architecture, multiple framework, professional tool for embedded systems engineers and for software developers who write applications for embedded products.
 
 - [PlatformIO - A professional collaborative platform for embedded development](https://platformio.org/)
 
+PlatformIO is not yet extensively adopted in industrial and large-scale projects, however, it is an excellent choice for individuals working on smaller projects. This is because it greatly reduces the need to install frameworks and setup build and debug tools, allowing you to concentrate on programming.
