What is the difference between application and firmware development?

Embedded software development encompasses the development of firmware, operating systems, device drivers, and application software. Meanwhile, firmware development is narrowly focused on the low-level software stored in the non-volatile memory of embedded systems.

When it comes to embedded firmware development, Yalantis is dedicated to the intricacies of low-level development for clients’ hardware. As a firmware development services provider, Yalantis:

  • enables microcontrollers and microprocessors to collect and transmit data from sensors to nodes or gateways
  • initializes modules responsible for data operations
  • empowers hardware to execute specific actions in response to commands.

How does your company approach firmware development for different types of projects?

Yalantis adopts a tailored approach to firmware programming based on your business objectives and the specific requirements and characteristics of each embedded system.


As a firmware development company, we start with a comprehensive analysis of the client’s needs, the intended application, and the target hardware. Our experienced team then designs a customized firmware architecture that aligns with the system’s functionalities and performance requirements. We prioritize efficiency, reliability, and optimization, ensuring that custom firmware is well-suited for the intended embedded system.

What industries do you have experience developing firmware for?

Yalantis brings extensive firmware development expertise across various industries, including EV chargers, healthcare, supply chain, wearables, automotive, smart homes, drones, and industrial solutions. Our expertise is showcased in the full-cycle development of embedded systems, encompassing:

  • firmware development
  • device prototyping and implementation roadmap design (in cases where our clients have their hardware vision, we conduct a comprehensive audit to assess feasibility and propose enhancements)
  • application-level development

In industrial settings, we prioritize the discovery stage to understand our clients’ equipment operation requirements. If needed, Yalantis developers can integrate your solution with large systems (such as SCADA or digital twins) and include them in a firmware development roadmap. Our range of programming languages for embedded firmware development includes C++, C, and Rust.

How do you address challenges related to low-level programming and optimization for resource-constrained environments?

Addressing challenges associated with low-level programming and optimization is a core strength of our firmware development team and part of our firmware development services. We have a deep understanding of hardware architectures and use efficient coding practices to optimize resource use. Our firmware developers are proficient in writing low-level code that maximizes performance while minimizing memory and processing power requirements.


We exploit rigorous testing and profiling techniques as part of our custom firmware development services to fine-tune custom firmware for resource-constrained environments, ensuring optimal functionality within specified limitations. Our experts also employ various optimization techniques, such as compilers and trade-off optimization for execution time and memory.

What is your approach to testing and quality assurance in firmware development projects?

Adhering to industry best practices, we integrate comprehensive unit testing, integration testing, and system testing throughout the development life cycle.


Our testing processes are designed to identify and address issues related to functionality, performance, security, and reliability. We have extensive experience performing testing on emulators, prototypes, as well as production devices.


As a custom firmware development company, Yalantis also has a team of manual QA professionals who can work with hardware, testing its real capabilities in addition to simulations.


Additionally, in terms of firmware development services, we conduct extensive validation testing against specified requirements, ensuring that firmware not only meets but exceeds client expectations. Continuous testing, feedback loops, and a steadfast commitment to quality standards are integral components of our firmware testing approach.

What types of tools and technologies do you typically use in firmware development, and are you open to using a client’s preferred tools?

Our firmware development team is proficient in a variety of industry-standard tools and technologies. We commonly use integrated development environments (IDEs), version control systems, and debugging tools that streamline the firmware development process, including:

  • IDEs: Keil UVision, STM32CubeIDE, Visual Studio Code
  • Debugging tools: GDB, Logic Analyzer
  • GUI development: Qt framework
  • Additional tools: CMake, Make, Conan

Of course, we are open to using a client’s preferred tools, understanding that compatibility and collaboration are crucial. Flexibility in tool selection allows us to seamlessly integrate with our clients’ existing workflows and toolchains, ensuring a collaborative and efficient development process.
