Firmware & Embedded Systems

Firmware is what makes your board work. We write reliable, efficient code for the microcontroller at the heart of your product.

Because we also design the hardware, the board and its firmware are developed together, not in isolation.

What we do

Firmware in C and C++ — bare-metal or on a real-time operating system (FreeRTOS)
Microcontrollers — ESP32, STM32, PIC, AVR and Nordic nRF
Peripheral drivers — sensors, displays, motors, ADC/DAC, PWM and power management
Communication — UART, SPI, I²C, CAN, Modbus, USB, Ethernet, Wi-Fi and Bluetooth Low Energy
Motor control — speed and position control for DC, brushless (BLDC) and stepper motors
Bootloaders and over-the-air (OTA) updates — update devices in the field without opening the box
Low-power design — longer battery life through sleep modes and efficient code

Upgrading an older product?

Components go obsolete, and the original source code is often lost. We rebuild your board around a current microcontroller and rewrite the firmware to match. Connectors and behaviour stay the same, so the new board drops into your existing equipment.

Case study: a conveyor oven speed-control board moved from an obsolete PIC to an ESP32.

How we deliver

Every firmware release is tested on real hardware before it reaches you. You receive documented releases with version history, and we stay available for fixes and new features after launch.
