 # 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, the topics have been carefully selected based on current job requirements and organized according to 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.
+[Making Embedded Systems](https://www.oreilly.com/library/view/making-embedded-systems/9781449308889/): An embedded system is a **computerized system** that is **purpose built for its application**.
 
-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.
+[Analog Devices](https://www.analog.com/en/design-center/glossary/embedded-system.html): An embedded system is a system in which the **computer** (generally a microcontroller or microprocessor) is included as an integral part of the system.

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](https://barrgroup.com/embedded-systems/glossary-e): 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.

 Additionally, the [Arduino Core](https://github.com/arduino/ArduinoCore-API) 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.
