Firmware and Embedded Software
Embedded firmware written for performance, power efficiency and long-term maintainability, on hardware we understand because we designed it.
Firmware development is usually what decides whether a product feels finished or feels broken. We have shipped embedded software across a wide range of MCUs and applications, from bare-metal low-power sensor nodes to RTOS-based systems driving displays, radios and motor control.
What this includes
- Board bring-up, bootloaders, drivers and HAL development
- RTOS integration and bare-metal embedded development
- Low-power architecture and measured battery-life optimisation
- BLE, Wi-Fi, LoRaWAN and cellular connectivity
- Sensor fusion, DSP and real-time data processing
- Over-the-air (OTA) update systems with rollback
Embedded systems development across the stack
We work from board bring-up upwards: bootloaders, drivers and hardware abstraction, RTOS integration and application logic. Because the same team designs the electronics, firmware problems that are really hardware problems get identified early rather than being worked around in software for months.
Low-power design that survives contact with a battery
Battery life is decided by architecture, not by tuning at the end. We design duty cycling, peripheral power domains and wake sources up front, then measure real consumption on real hardware instead of trusting datasheet figures. Where a product has a battery target, we treat it as a requirement to be verified rather than a hope.
Connectivity, sensor fusion and OTA updates
We build BLE, Wi-Fi, LoRaWAN and cellular connectivity into products, along with the sensor fusion and signal processing needed to turn raw readings into something useful. Products that ship to customers need a way to be fixed in the field, so we design over-the-air update systems with rollback and integrity checking rather than bolting them on later.
Common questions
Can you write firmware for hardware we already have?
Yes. We regularly pick up existing hardware, including boards designed elsewhere, and take over or extend the firmware. We start with a short review so that we can be honest about whether the hardware can actually meet your requirements.
Do you take over maintenance of existing firmware?
Yes, including undocumented legacy code. The first step is usually a review that establishes what the code does, what the risks are and what it would cost to make it maintainable, before committing to a longer engagement.
