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.

Frequently Asked Questions About Embedded Software Development

What Is Embedded Software Development?

Embedded software development focuses on creating code that controls and manages hardware devices. Unlike desktop or web software, embedded programs run directly on specialized processors or microcontrollers, often with limited memory and power. This software determines how a device responds, communicates, and performs in the field.

How Is Embedded Software Different from Firmware?

The difference usually comes down to scope and abstraction. Firmware operates at a lower level, managing hardware directly, while embedded software can include higher-level logic or user-facing functions. Many products contain both, and Think Circuits develops each layer to work together seamlessly.

What Types of Embedded Systems Does Think Circuits Develop For?

We work with everything from ultra-low-power sensors and wearable devices to Linux-based platforms running AI workloads. Our team supports systems built on ARM, RISC-V, and custom SoC architectures. Whether your hardware is resource-constrained or performance-driven, we can develop software that fits its operational profile.

Do You Develop Bare-Metal Applications?

Yes. Bare-metal systems operate without an operating system, offering full control over hardware and timing. This approach is ideal for devices that must run efficiently within tight resource limits. We write lean, deterministic code that keeps response times fast and predictable.

When Is an RTOS the Right Choice?

A real-time operating system (RTOS) is best for products that need multitasking, synchronized communication, and predictable timing. Systems like FreeRTOS and Zephyr give structure to complex embedded applications. We help clients evaluate whether an RTOS architecture makes sense based on performance and power needs.

Do You Build Software for Embedded Linux Systems?

Yes. We develop applications for embedded Linux platforms such as those using Yocto or Buildroot. Our work includes user-space programs, network services, and lightweight graphical interfaces for edge devices that handle camera input, local inference, or data processing.

How Do You Integrate Sensors and Communication Modules?

Our engineers write custom drivers and device interfaces for sensors, radios, and power systems. We configure communication protocols such as SPI, I2C, UART, and USB, handling timing and buffering at both hardware and software levels to achieve stable and reliable data flow.

What Programming Languages Do You Use for Embedded Software?

Most of our embedded work is written in C and C++, though we also use Rust and Python for specific applications. The language and toolchain depend on processor type, available libraries, and project requirements.

How Do You Test Embedded Software?

We test across multiple stages, including simulation, integration testing, and live hardware validation. Our engineers perform timing analysis, stress testing, and sensor simulation to evaluate reliability under real conditions. The goal is to confirm stability long before field deployment.

Can You Improve Existing Embedded Code?

Yes. We often join projects midstream to optimize or stabilize existing codebases. That may include debugging memory issues, improving startup time, or reducing power consumption. We also document systems and provide handoff support for internal teams.

How Does Think Circuits Work With Client Engineering Teams?

We integrate directly with your workflow. Some clients bring us in for specific subsystems, while others rely on us for full software architecture. We coordinate with electrical and mechanical engineers so that software and hardware progress together without roadblocks.

What Makes Software Reliable in Embedded Systems?

Reliability comes from deterministic design and robust error handling. We structure code to manage unexpected states, handle power interruptions, and recover cleanly. Testing for edge cases and validating under variable conditions helps prevent failures in the field.

Can You Support Hardware Bring-Up?

Yes. We frequently help clients during hardware bring-up, writing board support packages and boot code. This phase is critical for validating communication between processors, peripherals, and sensors before higher-level software development begins.
