C++, FPGA, emulated CPU programming, ARM Cortex Lauterbach debugger

Client challenge/business need

In 2002, Danfoss had begun development of its new generation of frequency converters and was looking for nearshoring possibilities.

Solution at a glance

We became partners and Proekspert started as a team fully integrated within Danfoss’ Danish team.

A few years later, what started out as a team grew into a development center responsible for Danfoss VLT drive AQUA (FC 202) and HVAC (FC 102) development.


  • Focus on the drives
    Development of existing and next-generation electric motor drives software.
  • All sorts of projects
    Platform development, Aqua and HVAC development, customer-specific branded versions, application development.
  • A different kind of innovation
    Proekspert has brought many innovative ideas to Danfoss over the years. Some came from teams, others were the result of hackathons. Some of these ideas – like VLT Software Customizer, smart LCP, and smartwatch – Danfoss has taken into production.

Embedded Software FAQs

What is embedded software?

Embedded software, uniquely programmed for non-computing devices, controls specific functions directly within or atop a microchip. Unlike versatile PC software, it is tailored for fixed hardware, ensuring optimal performance within the device’s processing and memory limits. This encompasses applications, firmware, middleware, and operating systems running on embedded microprocessors integral to the device’s functionality.

What are the different types of embedded software and their purposes?

Operating System (OS) – An OS is a critical software enabling the operation of applications on a computing device. It oversees the management of hardware resources, such as input/output devices and storage, and offers services for effective software execution, including memory management.

Firmware – This specific software is embedded directly into the hardware, providing essential instructions for the device to perform basic operations or communicate with other devices, bypassing the need for APIs, operating systems, or device drivers.

Middleware – Positioned between applications and the OS, middleware facilitates software development in distributed systems by abstracting the complexity of these systems. It offers uniform interfaces, hides hardware and software diversity, and provides standard services to enhance interoperability and reduce redundancy.

Application – This represents the software developed by the end-user, operating on the OS and interacting with middleware and firmware. Unlike the more standardised OS and firmware, it is the primary component of the embedded system’s functionality, tailored to specific tasks.

What are the different types of embedded systems?

Based on performance and functional criteria, embedded systems are categorized into five principal types:

1. Real-time Embedded Systems: These systems execute tasks within fixed time constraints, ensuring deterministic and consistent outcomes. Their efficiency is influenced by the OS’s architecture, thread performance, and the handling of interrupts and branching.

2. General-purpose Embedded Systems: Unlike real-time systems, these do not require adherence to strict timing for task completion. They handle interrupts and branching flexibly, ideal for managing peripherals like graphics displays and input devices.

3. Stand-alone Embedded Systems: These systems operate independently of a host or external computing resources, capable of processing input and output with connected devices without dependence on them for task completion.

4. Networked Embedded Systems: These systems rely on network connections to perform their functions, integrating with other systems across a network to perform their tasks.

What’s the difference between Embedded Software and Embedded Systems?

An ’embedded system’ refers to the hardware components of a device that operate embedded software. Key hardware elements in embedded systems include power supply circuits, central processing units (CPUs), flash memory devices, timers, and serial communication ports. In the initial design stages of a device, the composition and arrangement of the embedded system’s hardware are determined. Subsequently, embedded software is tailor-made to function solely with this specific hardware setup. This necessitates a specialized approach to embedded software design, demanding comprehensive expertise in both hardware functionalities and computer programming.
