Embedded system software development process

Embedded System Design: Short Review To get a more complete understanding of the development process of embedded systems, we need to start with a few words about what they are. Embedded systems have some distinctive features: programmed to perform a small range of functions no more than ; controlled by an integrated system; a wide range of uses — embedded system design examples include portable user devices, household appliances, and large units that are used in industry.

This group usually includes: firmware developers whose main task is to ensure the smooth operation of devices after installing firmware; suppliers of individual components for embedded systems — controllers, microprocessors, various sensors, etc; manufacturers of devices the embedded system will be integrated in — household appliances, automobiles, industrial equipment, etc.

Main Stages of Embedded System Design Process The entire process of working on the design of embedded systems can be thought of as a chain of interconnected steps. Source Some stages can be combined.

The essence of each of these steps in the embedded product development process can be described as follows: Abstraction. This stage can also be defined as developing the idea or basic concept of a future system product. Before starting work, we determine the essence of the problem, create the plan for future work, draw up a specification for all components of the future device.

Development of project layout. It is at this stage of the embedded software development process that components for the future system are chosen, namely microcontrollers and other physical components. Development of software architecture. At this stage of embedded product development , developers choose the tools and programming languages that will satisfy the system requirements of the project. A printed circuit board and a prototype of the system are created.

The printed circuit board provides the necessary functionality for the embedded system. The prototype involves checking the operation of the system with all its constituent components. Firmware development. At this stage of the embedded software development process , engineers integrate the previously developed software with the mechanical components of the future device. This stage is one of the most laborious, since it is here that developers write the code to ensure the operation of the system hardware components.

So if you want to add new features to your solution, the need for embedded systems will only increase. The medical area is actively being digitalized and requires the development of embedded systems. These can be wearable and portable devices that control and record the state of your health and monitor the necessary signs.

Embedded systems can be large and small and are responsible for different activities and broad them to the doctors. These systems give the possibility to control the patients in medical facilities as well as on a distance. Embedded systems are a crucial component of every electronic product.

For example, connecting consumer electronics like smartphones, smartwatches, security systems give great value to the embedded systems. Wondering whether your business can benefit from the embedded software? The filling of the embedded system depends on the level of complexity of the software solution, its goals, requirements, and the sphere of usage. Modern embedded systems use microcontrollers, microprocessors, and other programming tools for integrating with devices. Nevertheless, there are main units and elements that fill in any embedded system.

They are the following:. There are already popular tools for embedded systems development on the market. They are widely used for different programming languages to control the whole process of development. Here are some of them:. PyCharm is an integrated development environment suitable for Python programming language. It gives the features for code analyzing, design exterminator, and testing. So what exactly does this tool do? The features are the following:.

WebStorm is another integrated development environment created by the JetBrains company. The main functions of this development tool are:. Qt Creator is considered to be the most popular integrated development environment. It is used for developing all types of solutions among which are the medical sphere, mobile applications, automotive, and others.

So there key features that suit to different types of solutions:. This tool is created to develop solutions for diverse types of microcontrollers and digital signal controllers. It is supported by Windows, Mac, and Linux operating systems. Talking about features, some of them should be mentioned:.

This tool is very popular for a reason. Compared to other IDEs it has some benefits like simple usage, auto-completion that helps to complete the header files automatically, real-time checker of syntax to define and change the errors. Detailed Technical Specification. Architecting the Solution. Creating a Test Plan. Field Trials. Final Product Improvements. Product Launch.

So, is it possible to approach the problem differently and lead to the synergy of engineers and programmers? The agile software development methodology abandons a linear, sequential action framework for an iterative-incremental approach such as Scrum. Product development is divided into sprints of a certain time interval and takes into account the current contact between teams or the creation of one interdisciplinary team of specialists.

Such teams are multifunctional and self-regulating; they bring together planners, designers, engineers, programmers and testers while abandoning any organizational hierarchy. Instead of extensive planning and design in advance, the project is carried out from iteration to iteration. It should be possible to present the working version of the product to the product owner at every stage.

Feedback can then be implemented at the next stage of work. Developers are the ones to decide how to achieve the set goals. This is particularly important since software decisions are often reactivated, and developers complain about too late quality control, which translates into delays. This does not mean that you should entirely shift away from specification or defining milestones.

However, the requirements defined at the beginning of the project are often too vague and subject to change, and their current definition allows better adjustment of the software to the real needs. Because agile programming assumes close cooperation and effective communication, the team should set out the time needed for the next sprint, the necessary resources and divide tasks between themselves.

However, short meetings should take place daily. Even if they were to boil down to contact between project managers and be conducted at a distance via a messenger. It is worth spending 15 minutes to detect any difficulties. During the sprints, the client should have insight into progress instead of being merely a passive observer. His satisfaction is a priority, and it leaves a free hand only in terms of methods for obtaining positive results.

It all boils down to the assumptions of agile software defined in in the so-called Agile Manifesto; the declaration reads:. This may be surprising due to the fact that their beginnings date back to the s.

At that time, the machine code set of processor commands in the form of binary numbers originating from the times of zero-generation computers enjoyed great popularity. This meant writing a large number of lines of code by hand. In at Bell Labs, Ken Thompson invented the B programming language, which optimized this process. However, the new language lacked data types and structures.

Dennis Ritchie took four years to complete the missing functions and thus invented the C language. In , he managed to implement the UNIX operating system kernel and thereby standardize the programming language on this platform. The evolution was completed by Bjarne Stroustrup[KZ1] , a PhD student who compiled the C and Simula languages, which greatly facilitated object-oriented programming.
