Firmware Development Services

Firmware Development Services

We create custom embedded software for a wide range of microcontrollers (MCU) and digital signal processors (DSP). Our team provides RTOS, ROS, and non-OS based firmware development services.

We offer various firmware development services, including creating low-level firmware, modifying and debugging existing firmware to optimize performance, and developing firmware for multi-protocol and system-on-chip (SoC) devices. As a firmware development company, we have extensive experience working with hardware, operating systems, low-level diagnostic and performance tools.


RTOS Development

Our experts develop RTOS-based firmware for solutions that demand real-time response. We work with FreeRTOS, Zephyr, ThreadX, RTEMS, LiteOS, NuttX, and other real-time operating systems. RTOS significantly speeds up the firmware development process.


ROS Development

Integra’s firmware developers have extensive hands-on experience with the Robot Operating System (ROS), a set of software libraries and tools designed to control low-level hardware in robots and robotic automation systems.


Non-OS Based Embedded Firmware

When an embedded device needs to run a set of tasks continuously and sequentially, or until the power supply is removed, we develop bare-metal firmware without using any operating system. This approach allows you to gain control over embedded system resources to improve efficiency, reduce costs, and meet specifications.


Cortex-M Family

The ARM Cortex-M processor family is the most common platform we work with. Depending on the requirements, we use different versions of Cortex microcontrollers: M0/M0+, M4/M7, and the Cortex-R family.


AVR, PIC, MSP430, etc.

We apply AVR, PIC, and MSP430 microcontrollers, which may be well suited for some specific tasks. We recommend using more powerful architectures in embedded development to avoid significant investment when moving from one platform to another.


DSP Firmware Development

Our experts develop RTOS-based firmware for solutions that demand real-time reWe develop DSP firmware when the device requires algorithmic processing on the microcontroller and real-time digital signal processing. Integra’s engineers have extensive experience working with the C6000 and C5000 series DSP processors from Texas Instruments, dsPIC from Microchip Technology, and ADSP-21xx, Blackfin, SHARC, and TigerSHARC from Analog Devices. sponse. We work with FreeRTOS, Zephyr, ThreadX, RTEMS, LiteOS, NuttX, and other real-time operating systems. RTOS significantly speeds up the firmware development process.



The hardware abstraction layer (HAL) enables the development of reusable and hardware-independent firmware. HALs are essentially APIs for interacting with hardware. We use existing HALs provided by microcontrollers and compilers and create custom ones.


Testing Services

Testing includes firmware debugging and optimization. We test each firmware part individually using all possible scenarios and apply manual and automated testing methods to deliver reliable, high-performance products.


Migration of Legacy Firmware to New Platforms

We can help you migrate the firmware from one MCU to another, preserving all the features and programming models unique to the product. We can change the PCB layout and make the design portable.
