Engineering service
Firmware Development
Embedded firmware for ARM Cortex-based microcontrollers and other widely used embedded platforms: architecture, drivers, RTOS or bare-metal code, communication protocols, bootloaders and OTA updates.
Intended buyers
Who uses this service
- Product teams that need firmware written for new hardware.
- Manufacturers with existing products that need firmware changes, fixes or new features.
- Hardware teams that need drivers, board bring-up or communication stacks alongside their own work.
Firmware stack
Every layer, from boot to cloud
Firmware is a stack, and each layer depends on the one below it. We write all of it, or the layers your team does not cover. The tags show where each layer appears in our published projects.

- ConnectivityNetwork stacks and industrial and IoT protocols, secured where neededModbus RTU/TCP · MQTT · TLS

Scope
What we cover
Real-time operating systems, bare-metal drivers and secure bootloader pipelines with OTA delivery. Protocol stacks are chosen for the application, not the trend: MQTT, BLE, Modbus, CAN and LIN. Work runs on Git-based version control with hardware-in-the-loop CI, release tagging and configuration management.
- M3·M4·M7Arm Cortex-M families in shipped products
- RTOSor bare metal, with an in-house embedded framework
- OTASigned slots, version revert, staged rollouts
- HIL CIHardware-in-the-loop testing on Git
Architecture and design
Firmware structure planned around your hardware, timing and maintenance needs.
Drivers and peripherals
Peripheral drivers and integration, including UART, SPI, I2C, ADCs, displays and memory.
RTOS and bare-metal
Real-time, RTOS-based firmware, or bare-metal code where that suits the product better.
Communication
Ethernet, Wi-Fi, Bluetooth LE, MQTT with TLS, CAN, LIN and industrial protocols such as Modbus RTU and TCP.
Bootloaders and OTA
Bootloaders and over-the-air updates, so products can be updated in the field.
Maintenance
Enhancements, fixes and long-term firmware support after release.
Tell us your microcontroller family and toolchain in the enquiry. If your product must meet a specific standard, name it so we can confirm the approach before work starts.
Applications
Firmware in our projects
Examples from Nuvologic’s published projects.
- Industrial weighing: bootloader, RTOS and emWin GUI, with TCP/IP, Modbus RTU and TCP, PID control, logging and printer output.
- Weight indicator: RTOS firmware on an in-house embedded framework, with menu navigation and secure data storage.
- Connected devices: MQTT, HTTP/HTTPS, BLE and Wi-Fi with TLS, OTA updates and time synchronization.
Customer inputs
What to send us
- 01HardwareMicrocontroller, schematics and board status.
- 02FunctionsWhat the firmware must do, and any timing requirements.
- 03InterfacesPeripherals, communication links and protocols involved.
- 04Existing codeCurrent source code and toolchain, if the product exists.

Deliverables
What you receive
Deliverables, source code ownership and hand-over are agreed in the proposal. Depending on the scope, they can include:
- Firmware for the agreed functions, tested on the target hardware
- Bootloader and update mechanism, where required
- Test results against the agreed requirements
- Ongoing support and enhancements, if agreed
Process
How firmware work runs
- 01
Requirements and hardware review
Functions, interfaces and the target hardware.
- 02
Architecture
Structure, RTOS or bare-metal choice and update approach.
- 03
Implementation and integration
Drivers, application logic and communication, with regular reviews.
- 04
Testing and release
Tested on the hardware against the agreed requirements, then released and supported.
Which microcontrollers and platforms do you support?
We work with ARM Cortex-based MCUs and widely used embedded platforms. Tell us your microcontroller and we will confirm.
Do you develop RTOS-based firmware?
Yes. We develop real-time, RTOS-based firmware, and bare-metal firmware where that suits the product better.
Which communication protocols do you implement?
Protocols such as UART, SPI, I2C, Ethernet, Wi-Fi, Bluetooth and industrial protocols. Our projects include Modbus RTU and TCP, MQTT and HTTP/HTTPS with TLS.
Can you work on firmware written by someone else?
Yes. Share the existing source code and toolchain and describe what needs to change; we review it before agreeing the scope.
Do you support firmware updates and long-term maintenance?
Yes. We provide OTA updates, enhancements and ongoing firmware support.
