How to Be an Embedded Software Engineer: Introduction
The present-day world is increasingly driven by smart devices. Therefore, the role played by embedded software engineering is crucial in shaping the technology of today. Embedded software engineering gives “brains” to these machines, if we put it in the simplest words. This could range from the microcontroller in your washing machine to the advanced control system in an electric car. Are you fascinated by how software interacts with hardware? Do you like building such systems? Then embedded software engineering is the best career path for you. This blog will take you through all the important points that will answer the question in your mind, “How to Be an Embedded Software Engineer”.
What is Embedded Software Engineering?
The software must be efficient, reliable, and often run in real-time—meaning it must respond to events within strict timing requirements.
Embedded software engineering is one of the latest branches in the field of software development. It focuses on creating software that controls hardware. This is worlds apart from desktop or web applications that run on general-purpose computers. The embedded software runs on specialised computing devices designed for specific tasks. Such devices operate under many tight constraints, such as:
- Limited memory
- Limited processing power
- Limited energy availability
Therefore, they must be efficient, reliable, and often run in real-time. This means these devices have to respond to events within strict timing requirements. Some examples of Embedded Systems are:
- Smart thermostats
- Automotive ECU (Engine Control Unit)
- Wearable health devices
- Industrial automation controllers
- Drones and robotics
- Consumer electronics like TVs, microwaves, and cameras
