Firmware
Code That Ships on Time
Firmware development is where hardware meets software, and where devices come to life. Our engineers have built firmware for everything from battery-powered sensors that run for years on a coin cell to high-performance embedded Linux systems driving complex touchscreen interfaces. We write code that’s reliable, maintainable, and ships on schedule.
What We Build
Bare-metal embedded systems
Low-level firmware for microcontrollers from 8-bit devices to 32-bit ARM Cortex processors. We work with all major embedded platforms, including Nordic, Silicon Labs, STMicro, Renesas, Microchip, Infineon, NXP, Qualcomm, and Texas Instruments.
Real-time operating systems
FreeRTOS, Zephyr, and custom RTOS implementations for applications requiring deterministic timing and task scheduling.
Embedded Linux
Board support packages, kernel modules, device drivers, and application development for Linux-based embedded systems. We handle everything from boot optimization to custom GUI development with touchscreen support.
Wireless protocol stacks
Both standards-based stacks and proprietary wireless solutions, including Bluetooth/BLE, Wi-Fi, ZigBee, Thread, LoRaWAN, Matter, Cellular, and custom RF protocols.
Communication protocols
USB (device, host, OTG), Ethernet, CAN, Modbus, I2C, SPI, UART, and TCP/IP.
DSP algorithms
Audio processing, signal filtering, FFT implementations, and real-time data analysis on both microcontrollers and dedicated DSP hardware.
User interfaces
Button and LED interfaces, character LCDs, graphical OLED and LCD touchscreen displays with hardware acceleration, and web-based configuration interfaces.
Development Process
Architecture and processor selection
We evaluate your requirements and select the optimal processor and firmware architecture for your product’s performance, power, and cost constraints.
Board bring-up and testing
We create test code to verify new hardware quickly, working closely with our electrical team to debug issues at the hardware-software interface.
Driver development
Low-level drivers for peripherals, sensors, communication interfaces, and custom hardware.
Application development
Feature implementation, state machines, user interface logic, and integration of third-party libraries or protocol stacks.
Testing and debugging
Unit testing, integration testing, and system-level validation using our labs equipped with logic analyzers, protocol analyzers, and JTAG debuggers.
Production support
Factory test code development and support during manufacturing ramp-up.
Why Firmware Matters
A great circuit design sitting on your bench doesn’t do much until someone writes code that brings it to life. We’ve optimized code for battery-powered IoT sensors that need to run for five years, debugged firmware in medical devices where failure isn’t an option, and built Linux systems that boot in under two seconds.
The difference between firmware that works in the lab and firmware that ships in volume is experience with edge cases, error handling, power management, and all the details that only show up when you’ve done this a few hundred times.
