Is Embedded Career All About C and Microcontrollers? Understanding Required Electronics Knowledge

The Role of C and Microcontrollers

When considering a career in embedded systems, there's a common misconception that it revolves solely around Embedded C and microcontrollers. While these are fundamental components, understanding the broader field requires a solid foundation in basic and digital/analog electronics, along with skills in PCB design and other hardware aspects.

Basic Electronics Knowledge

In an embedded system, you'll frequently interface with various components such as LEDs, LCDs, switches, relays, motors, and sensors. A working knowledge of how to connect and utilize these components effectively is essential. This includes understanding their operation, their roles in the system, and how to optimize their performance for cost efficiency and improved product functionality.

Digital Electronics

Embedding systems often deal with digital signals and data. Knowledge in digital electronics is crucial. This includes understanding number systems, the use of registers, and how to handle registers in microcontrollers. Additionally, knowledge of interrupt handling, encoders, decoders, ADCs (Analog-to-Digital Converters), UARTs (Universal Asynchronous Receiver Transmitter), and parity management are also important.

Analog Electronics

When interfacing with devices that produce analog outputs, such as sensors, understanding the nature of these devices and the Analog-to-Digital Converters (ADCs) that process them is necessary. Key knowledge includes the function and usage of ADCs, as well as their registers.

Printed Circuit Board (PCB) Designing

PCB design is a critical aspect of embedded systems. It involves not only the layout of the circuit but also ensuring the complexity is kept to a minimum. PCB designing requires a focus on the interconnectedness of components and how they should be arranged to achieve optimal performance. With a good understanding of PCB design, you can create circuits that are both efficient and productive.

Skills and Responsibilities

As an embedded software engineer, you will need to read and understand technical datasheets and reference manuals for micro-controllers and the components with which they interface. While you may get some assistance from the hardware engineering team, you are expected to be competent enough to navigate these documents and understand the schematics on your own. However, specific tasks like PCB design, hardware troubleshooting, and power supply design are typically handled by experienced hardware design engineers.

Conclusion

While Embedded C and microcontrollers form the core of the embedded systems industry, a thorough understanding of electronics knowledge, including digital and analog electronics, is essential. Additionally, the ability to design and optimize PCBs is a valuable skill that provides a more holistic understanding of the embedded systems domain.
