Our Firmware Development Services
SCAND develops custom firmware for bare-metal (no OS) and RTOS-based systems, using microcontrollers from leading vendors. We solve performance bottlenecks, connectivity issues, and low-level integration problems, so your device meets its technical requirements and runs reliably in the field.
Custom Firmware Development
Off-the-shelf firmware rarely matches specific hardware, performance constraints, and product requirements. We handle firmware design and development around your device architecture, delivering production-ready code with a clear structure and documentation. This makes the firmware easier to maintain, extend, and adapt as the product evolves.
Bare-Metal Firmware Development
For devices that require precise timing, low power consumption, or minimal memory usage, SCAND develops bare-metal firmware that runs directly on the microcontroller. We design low-level code around your hardware and performance requirements, helping you achieve predictable device behavior.
RTOS Firmware Development
When a device handles several time-sensitive operations at once, poor scheduling can cause missed deadlines and resource conflicts. We build firmware on FreeRTOS, Zephyr, and other RTOS platforms, configuring task priorities, interrupts, synchronization, and shared resources to keep the system responsive under load.
New hardware needs a properly configured software foundation before application development can begin. SCAND creates board support packages, configures bootloaders and Linux kernels, and builds custom images with Yocto or Buildroot. This ensures reliable booting, peripheral support, and a stable environment for higher-level software.
MCU and Platform Porting
Component shortages, rising costs, or discontinued microcontrollers can make an existing platform impractical. We port proven firmware to new MCUs, vendors, and toolchains while preserving existing functionality. Our engineers also adapt drivers, peripheral interfaces, timing logic, and build systems where required.
Device Drivers and HAL Development
Tight dependencies between application code and hardware make firmware difficult to reuse or update. We develop device drivers and hardware abstraction layers for sensors, displays, memory, and other peripherals. This separates hardware-specific logic from application code and simplifies maintenance across product models and hardware revisions.
Communication Protocol Development
Unstable communication can prevent a device from working correctly with hardware, mobile apps, or cloud services. We implement BLE, Wi-Fi, MQTT, CAN, UART, SPI, I2C, and custom protocols, handling data exchange, timing, error recovery, and integration to keep connections reliable.
Firmware Testing, Validation and Security
Firmware defects often appear only on physical hardware or under unusual conditions. We use unit tests, hardware-in-the-loop setups, integration testing, and stress scenarios to verify behavior on target devices. We also implement secure boot, authentication, encrypted communication, and protected OTA updates.
Legacy Firmware Migration
Outdated toolchains, tightly coupled code, and poor documentation can slow further product development. We modernize legacy firmware through refactoring, architecture improvements, toolchain upgrades, and documentation updates. When appropriate, we also migrate bare-metal systems to an RTOS while preserving existing functionality.
Benefits of Embedded Firmware Development Services for Business
Embedded firmware development can improve product reliability, security, performance, scalability, and cost efficiency. With the right firmware architecture, businesses can reduce maintenance expenses, speed up product releases, optimize hardware resources, and support devices throughout their lifecycle.
Consistent Device Performance
Well-designed firmware keeps timing, response time, and error handling stable under real conditions. Your devices deliver the same results in the lab and in the field, which reduces returns, warranty claims, and complaints from customers who depend on your hardware every day.
Secure Device Connectivity
Secure boot, encrypted data exchange, authenticated connections, and protected OTA/FOTA updates: this is what security-minded connectivity looks like. Your devices then communicate with mobile apps and cloud services safely, while your company avoids data leaks, unauthorized access, and reputational damage.
Seamless Hardware-Software Integration
Our engineers work with your hardware team, mobile developers, and backend engineers as one group, treating hardware and software as a single system from day one. Firmware, sensors, apps, and cloud services fit together from the start. You avoid late integration surprises, redesign cycles, and delays that push back your launch date.
Optimized Power and Resource Usage
Memory, processing power, and battery budget shape every decision we make when tuning firmware for power efficiency. Efficient code extends battery life, allows more affordable microcontrollers, and lowers your bill of materials, improving the experience of any battery-powered product.
Scalable Product Architecture
We use a modular structure with a clean hardware abstraction layer. Your team can add features, support new hardware revisions, and expand the product line without rewriting the core. Development of each next device becomes faster and more predictable.
Lower Maintenance Costs and Longer Product Lifecycle
Documented, tested code and OTA update support let you fix defects and ship improvements remotely. You avoid costly recalls and on-site service visits, and your product stays competitive and secure for years after the first release.
Custom Firmware Projects Use Cases
Firmware keeps embedded and connected devices reliable, secure, and efficient, provided it is built around the requirements of specific hardware. SCAND delivers custom firmware for new products and existing devices across industries. Below are the project types where our engineering work brings the most value.
Industrial Automation and Manufacturing
We develop firmware for automation equipment, motor and power controllers, sensor nodes, gateways, and control panels. Deterministic timing, fault tolerance, and industrial interfaces such as CAN, RS-485, and Modbus keep equipment running continuously in demanding environments.
We build firmware for devices that collect data, exchange it with mobile apps, and send it to the cloud. Stable connectivity, low power consumption, and secure OTA updates let you manage large device fleets without on-site service.
Healthcare and Medical Devices
We create firmware for wearable devices, portable medical devices, and monitoring equipment. Accurate sensor data processing, long battery life, and predictable behavior improve user experience and support the long-term reliability that health-related products require.
Firmware Optimization and Security
We improve firmware that is already in production and running stably, but which needs to be made faster, use fewer resources, or have security vulnerabilities fixed without a complete rewrite of the code or a change in platform.
Custom Embedded Firmware Development Solutions for Modern Devices
SCAND builds custom firmware solutions for your specific hardware and product goals. We start from your board, sensors, connectivity, and power budget, then design firmware that fits them. Whether you launch a new device or upgrade an existing one, the result is software that matches your requirements.
Connected Device Solutions
Unstable connectivity can disrupt device operation and integrations with mobile apps or cloud platforms. Our engineers develop firmware for wireless communication, device-to-device interaction, and backend connectivity, optimizing pairing, data exchange, reconnection, and error handling to keep communication stable and responsive.
Sensor and Data Processing Systems
Sensor-based devices need reliable data even with limited memory and processing power. We develop firmware that collects, filters, processes, and transmits sensor data using efficient algorithms and, where needed, on-device machine learning. Accurate sampling and buffering provide applications and analytics with consistent input.
Real-Time Control Systems
Motors, actuators, robotics, and industrial equipment cannot tolerate unpredictable delays. SCAND implements deterministic timing, interrupt handling, task coordination, and fault detection to keep control logic responsive and device behavior predictable during continuous operation.
Low-Power Embedded Devices
Limited battery capacity can restrict runtime, product size, and usability. Our team reduces firmware power consumption through sleep modes, event-driven logic, peripheral management, and optimized processing. This extends operating time and can reduce battery requirements for portable and IoT devices.
Secure and Updatable Devices
Devices that cannot be updated securely become harder and more expensive to maintain. We implement secure boot, signed firmware, OTA updates, rollback, and recovery mechanisms, helping you deliver fixes remotely, prevent unauthorized code from running, and recover from failed updates.
Edge Data Processing
Sending all device data to the cloud can increase latency, bandwidth use, and infrastructure costs. SCAND moves processing and decision-making closer to the device, helping products respond faster, reduce cloud traffic, and continue core operations during connectivity interruptions.
Firmware Technology Stack
SCAND selects the platform, operating system, and toolchain based on your hardware, performance targets, and budget. Our engineers cover the full cycle: design, development, testing, debugging, and secure updates.

Our Embedded Firmware Development Process
Our approach to firmware development keeps projects predictable, from first requirements to long-term support. Each stage has clear deliverables, so you always know what is done and what comes next.
-
2. Firmware Architecture and Planning
Before writing a single driver, we design the firmware structure, confirm platform and OS choices, and define modules, interfaces, and the update strategy. What your team gets is a roadmap with milestones and test criteria that keeps development on schedule.
-
3. Development and Hardware Integration
Drivers, application logic, and communication layers get written and tested on real boards from the earliest stages, not at the end, including board bring-up activities on new hardware revisions. Working closely with your hardware team, mobile developers, and backend engineers, we catch integration issues before they reach the release.
-
4. Testing and Performance Optimization
We run unit tests, hardware-in-the-loop tests, and stress scenarios, then profile memory, timing, and power consumption. Optimization continues until the firmware meets the agreed targets on your hardware.
-
5. Deployment, Updates, and Support
Release is not the finish line. We prepare firmware for launch, set up secure firmware updates, and deliver documentation, then continue fixing defects, adding features, and supporting new hardware revisions throughout the product lifecycle.
-
1. Requirements and Technical Assessment
Product goals, hardware, constraints, and target environment come first. From there, we define functional requirements, performance and power budgets, interfaces, and security needs together with you, so development starts with a clear scope, risk assessment, and estimate.
