Software Development Services For Embedded Systems

Embedded software is the intelligence behind modern hardware. It defines how a device behaves, interacts, and adapts to its environment. Whether you're developing a next-generation wearable, robotics platform, or smart sensor, the software inside determines how everything comes together.

Think Circuits specializes in writing embedded code that's stable, efficient, and tightly integrated with hardware. From real-time performance tuning to full software stacks, our work keeps devices running reliably in the field. For a discussion about your vision and our ability to help, send us a note.

Building Embedded Software That Delivers

The performance of a smart product depends heavily on the software running underneath. Code must launch reliably, stay responsive under varying conditions, and handle timing with consistency. We design each embedded system to match the product's physical footprint, power requirements, and expected behavior in the field.

Some projects call for simple, low-level control. Others involve multitasking environments, peripheral integration, and structured scheduling. Regardless of scale, the goal is to help your system run smoothly and predictably.

What We Develop

Our team brings together firmware, embedded OS experience, and application-level development across a wide range of platforms. The software we write supports everything from custom circuit boards to production-ready Linux systems.

Bare-Metal Firmware

For highly constrained systems, direct control over hardware can make all the difference. Bare-metal code eliminates unnecessary overhead and allows systems to operate with precise timing and minimal power draw.

This approach works best for devices like smart sensors, health monitors, and ultra-compact wearables that need maximum efficiency with limited resources.

RTOS-Based Systems

When multitasking and responsiveness are priorities, a real-time operating system provides structure without compromising performance. We work with FreeRTOS, Zephyr, and other RTOS environments to organize task scheduling, manage shared resources, and support real-time communication. This kind of architecture is common in robotics, automation, and connected devices that must handle multiple I/O points or simultaneous data streams.

Embedded Linux Applications

More powerful hardware opens the door to embedded Linux. Whether running on ARM Cortex-A processors or custom boards designed for edge inference, Linux-based systems allow for greater flexibility and feature depth.

We develop user-space services, background processes, and lightweight GUIs tailored to embedded constraints. These applications often support local AI, camera feeds, and network communication in edge devices used in fields like computer vision and neural interface technology.

Driver Development and Peripheral Integration

Devices often include unique sensors, communication modules, or power configurations. Our engineers write the software that connects these components to your system.

That includes device tree configuration, board support packages, custom drivers, and robust interfaces across SPI, I2C, UART, and USB. Timing, buffering, and fault handling are always part of the implementation.

Our Projects Reflect What's Possible

For a recent product involving a neural input headset, our embedded code handled high-frequency signal capture and transformation in real time. The system was designed to process input locally, reducing dependency on external compute power and minimizing latency.

Another example involved a machine vision system built for edge deployment. Our team developed a Linux-based software stack that coordinated camera control, data buffering, and real-time inference. Communication with other devices happened over a network layer built for speed and error recovery.

This is the kind of end-to-end work we support. Our work includes low-level timing, high-level logic, and inter-device communication.

We Work Alongside Your Hardware Team

No two embedded teams work the same way, and flexibility is built into our process. Some clients bring us in for focused development on a subsystem. Others rely on us to structure the full software environment.

We often work in step with hardware and mechanical engineering teams, allowing software development to progress in parallel with board layout, component selection, and enclosure design. If your team shifts direction or hits new technical constraints midstream, we adjust quickly and keep the momentum going.

Technical collaboration is a priority. You'll always know where things stand and how decisions are being made.

Code That Holds Up in the Field

Embedded software needs to survive real use, not just bench testing. To get there, we include edge case testing, performance profiling, and reliability checks as part of development.

Our validation process includes sensor simulation, stress testing, and response measurement under timing or power fluctuations. These checks help catch issues before they become costly. The result is firmware and embedded logic that can recover from error conditions and perform consistently across units.

We also document integration points and provide handoff support when products transition to manufacturing or certification.

Let's Build the Software That Runs Your Product

Don't let your embedded code be the bottleneck. If your product depends on software that runs cleanly, reacts quickly, and integrates tightly with your hardware, we're ready to contribute.

Whether you're building something new or improving a system already in progress, Think Circuits can support the development work that brings it all together.
