OVERVIEW
Embedded software development, is the process of software development integrated with the development of some physical product such as consumer products. Today’s Embedded systems are used for thousands of applications from digital watches and MP3 players, to large stationary installations like traffic light controllers, programmable logic controllers, and large complex systems like hybrid vehicles, medical imaging, and avionics.
Since the birth of Raspberry Pi in 2011 and Arduino a bit earlier, mostly used by the hobbyists, Embedded Systems have grown multi-folds. From professionals to students, hobbyists to DIY users alike, contributed to the growth of embedded systems and low-cost SBC like Raspberry and other hundreds of competing platforms, widely used in embedded applications.
Embedded system development involves designing, programming, and testing computer systems that are dedicated to performing specific functions within larger systems or devices. These systems are typically embedded within machinery, appliances, vehicles, medical devices, consumer electronics, and industrial equipment to control their operation and interface with the outside world.
Here’s an overview of the process involved in embedded system development
Embedded software development Process
Embedded systems require software to control their operation. This software is typically written in low-level languages like C or C++, although higher-level languages like Python are also becoming popular. The software is responsible for tasks such as reading sensor data, processing it, controlling actuators, and communicating with other systems.
Testing is a critical part of embedded system development to ensure that the system functions correctly and reliably under all conditions. This includes testing individual hardware components, testing the software on the microcontroller, and testing the integrated system as a whole. Debugging is the process of identifying and fixing any issues that arise during testing.
Once the embedded system has been developed and tested, it is deployed into the target environment where it will be used. Maintenance involves monitoring the system for any issues that arise in operation and making updates or modifications as necessary to ensure continued reliability and performance.
Throughout the development process, it’s important for embedded system developers to consider factors such as real-time requirements, power consumption, safety, security, and scalability to ensure that the final system meets the needs of its intended application.
