Zephyr RTOS Firmware & Driver Development
Service description
I design and ship production-grade embedded firmware on the Zephyr real-time operating system for microcontrollers and IoT devices. Whether you are prototyping a new sensor node or hardening a product for mass production, I turn your hardware into reliable, low-power firmware that behaves predictably in the field.
What I deliver: full board bring-up starting from a custom devicetree and Kconfig setup, out-of-tree drivers for your peripherals over SPI, I2C, UART and GPIO, and clean integration with the Zephyr sensor and device driver model. I implement BLE connectivity using the Zephyr Bluetooth stack, including GATT services, custom characteristics, pairing and power-optimised advertising. I build sensor acquisition pipelines with proper sampling, filtering and buffering, and wire everything into a robust threading and workqueue architecture.
My process is transparent. We start with a short scoping call to lock down the target SoC, toolchain and requirements. I set up a reproducible west workspace, deliver code in small reviewable increments, and validate on real hardware with logging and shell instrumentation. Every deliverable ships with build instructions, a documented devicetree overlay and unit or integration tests where practical.
Typical targets include Nordic nRF52 and nRF53, STM32, ESP32 and NXP boards. I focus on low power consumption, deterministic timing and maintainable code that your team can extend after handover. You receive complete source, a clean git history and documentation so nothing is a black box.
Order now and let us get your embedded product running on a modern, well-supported RTOS.
