Embedded Software Development Process: Steps, Applications & More Within

Did you know that the first embedded system was developed about 50 years ago? Interestingly, now embedded systems surround us at every turn of life. It exists in automobiles, transportation, medical equipment, communication, industrial automation, and more!!

By 2025, over 75 billion devices are projected to be connected via IoT. Well, no matter which industry you fall in, chances are that the competition to build the best devices is fierce. As embedded software development process/cycle has its complexities, you need to ensure that the embedded software solutions are error-free and work seamlessly with your devices to win the war.

This blog perfectly guides you with some of the vital points you should keep in mind before heading for embedded software development process.

But First, What is Embedded Development?

To put it simply, embedded development can be defined as the process of building and integrating the in-built software into a device. We all know that humans cannot function without a brain. Similarly, a device cannot be a smart device if it is not integrated with the embedded software.

The embedded application development and embedded software development are quite similar in nature.

Points to Keep In Mind While Developing Embedded Software

Debugging

Debugging is the process of removing existing errors on the particular software. It also detects potential errors in the software and works on it. Majorly, it’s done to avoid crashes or unexpected behaviour.

You must be aware of the complexities of an IoT product. With such high complexity, there tend to be complex software programs. Hence, it increases the chances of the irrational behaviour of the software.

Indeed, no one can design the software right off the bat. So, the developers will spend more time debugging the applications to avoid high bugs. Here are some ways to implement them in your embedded software development. You can also hire embedded software engineers that are experts in this field.

• Monitor variables, memory, and stack through multiple information windows.
• Timer counts, cycle counts, and instructions halted the complex program executions.

Device Support

In the embedded software development process, you have to be cautious with selecting devices. Your main goal is to develop software that works seamlessly with your device.

Yes, the embedded software developer should work on some permutations and combinations by which he can avoid errors.

For example, a product includes its specifications about its register and bit fields for effective control. A software developer needs to understand the intricacies of memories, registers of control elements.

By ensuring proper register description with memory maps all registers of control element. Hence, it can be easily identified across document by giving it a distinctive name.

Therefore , you need to check that the embedded software development matches the purchased devices.

Safety and Security Risk

Today, security has become a significant issue in the digital world. IoT applications are gaining a lot of popularity, and the nature of IoT is to interconnect with various devices. With this, one faces high-security issues in the IoT softwares. Hence, the risk of the devices being hacked is high.

Therefore, the embedded software developer must use a potential combination that minimizes the risk. There are certain aspacts to consider during integrating embedded system security solutions.

Also, safety checks are necessary while developing the devices as these devices are used in critical environments and extreme conditions.

Tech Support

When you are purchasing embedded software, then one thing you have to make sure of is to choose your vendors wisely.

While many people fail to realise that tech support is a vital aspect of your development process, as some vendors provide support via email or online forums, it may take a long time to get a response from their side.

Therefore, it is wise to spend more money purchasing embedded software from a vendor who provides proper technical support as it works great when you need instant help.

Compatibility

The first and foremost thing you can do is make sure you choose the right embedded system design process and software for your devices. Well, make a list of devices you need for your product.

Now, check that the embedded design software supports the devices. It has often been observed that the softwares is updated, and the devices are incompatible with the softwares.

Also, note that your current embedded sw development purpose is to support the developed device or multiple devices in the future. Check once that your software doesn’t fail for future devices, too, as it can be cumbersome to create new software.

Steps of Embedded Software Development Process

The steps in the embedded software development process are:

1. Jot Down the Product Specs

The first step in the embedded software development procedure is collecting all the possible data. This is practically the ‘Ideation Stage’. Basically, the product should answer two questions:

• Problem – What problems does the product solve? What value will it bring to the customer’s life?
• Price – What is the cost of production, and what price are you planning to sell it at?

2. Technical Specifications to be Integrated

It is a dumb idea to adjust the design repeatedly as and when there are new discoveries. Rather, it is a mindful idea to jot down and validate all the technological frameworks that should be used in the embedded software development process.

3. Structural Architecture

Just as it is important to build the zero, i.e., the foundation of a building, it is essential to formulate the architectural formation in software development process in embedded system.

• The software architecture includes:
• The final cut of the design
• Strategies involved
• Type of wired or wireless connectivity to be used
• Type of power supply
• How the firmware design will look like
• Web app/Cloud-based app/Desktop software/Mobile app design

On the contrary, the hardware design involves selecting the specific component for every aspect of the circuit’s parameters.

Combining the architecture blueprints, one can get closer to the execution of this flow chart in embedded systems development process.

4. PoC / Prototype Development

PoC stands for Proof of Concept. This document is specially drafted to note the details of the prototype software. In this stage, the prototype is developed and goes through thorough testing by quality experts.

It is crucial first to develop a prototype, ensure its topmost quality, and collect feedback. After ticking all these boxes, our team moves ahead with upgraded version development.

5. Testing & Field Trials

How to develop embedded software without running quality checks? But, you must be wondering why we have mentioned a separate stage for testing? Well, many times, we have come across products that give perfect results during lab testing sessions but don’t perform upto the mark when on the field.

So what’s the solution?

The testing team at Excellent Webworld ensures that the product performs more than satisfactory in field conditions.

6. Final Product Improvements

After several days, weeks, and months of rigorous field trials, we gather the product’s required improvements. We improve the test procedures with every use case. All this results in a perfect product.

7. Product Release

Now that the product is ready to be launched into the outer world for startup and enterprise use, two last things remain:

• The final journey is to get the hardware product certification that will be managed using this embedded software.
• We also help our clients with the documentation of the product page on their website, a quick introduction video, a helpful user guide, and, lastly, setting up the user support portal.

The Need of Embedded Software

It’s unlikely to step into the future without IoT. well, IoT has stepped into every part of our life, from smartwatch to smart cars and smart homes.

Embedded software is getting independent from the hardware they reside in. It would be capable of doing any function or achieving any objective on any programming logic device, and hardware limitations would no longer confine it.

We have just observed the birth of embedded software development systems. In the future, embedded software is here to stay contributing and improve the quality of life.

Undoubtedly, this embedded software is observing a rise, and the future demands more of it.

So, if you are looking for embedded solutions, it’s essential to keep the points mentioned above in mind.

Also, it’s vital to hire embedded engineers that are best for your project. Connecting with the right embedded systems development company will make your work seamless.
