Embedded Firmware Development
Firmware is where a product either works or doesn't. We write bare-metal and RTOS firmware for STM32, ESP32, PIC, dsPIC33 and AVR platforms — sensor integration, motor and power control, custom protocol stacks, and bootloaders built for devices that have to be updated in the field.
We come in at whatever stage you need. Sometimes that's a blank board and a datasheet. Sometimes it's inherited firmware nobody understands anymore, or a migration from a part that's gone end-of-life. We've done automotive OBD-II diagnostics, BLE wearables, battery management with charge balancing, and industrial control — the work varies, the discipline doesn't.
Every project is handled by the engineer who designed it. When something behaves strangely at 2am on your production line, the person you call is the person who wrote the code — not a support tier who has to go and ask.
Frequently Asked Questions – Embedded Firmware Development
Yes. We start by reading the code and understanding the hardware before changing anything — inherited firmware often has undocumented reasons for the way it's written.
Whatever the platform vendor supports natively — STM32CubeIDE, MPLAB X, ESP-IDF — plus our own build and test scripts. We don't lock you into a proprietary framework.
Yes. Prototype firmware and production firmware are different disciplines — the second has to survive field conditions, power loss, and years of updates. We do both stages.
Yes. You own what we build. We hand over source, build instructions, and enough documentation that another engineer could pick up the project.
We assess what's actually MCU-specific versus portable, then plan the migration around it — sometimes a like-for-like part swap, sometimes a deeper rewrite if the peripherals don't map cleanly.
