Behaviour & interface definition
Describe operating modes, inputs, outputs, fault responses and the interfaces the firmware must support.
Firmware development
Embedded firmware development
Microcontroller firmware, peripheral interfaces, application logic and debugging.
THE LOGIC BEHIND THE HARDWARE
Firmware connects the electronics to the intended user experience. We support application development and hardware-facing software, with interfaces, behaviour and handover requirements agreed at the start.
ENGINEERING SCOPE
Scope of work
The exact activities, depth of review and outputs are defined for your project.
Peripheral integration
Develop and integrate the agreed drivers and hardware interfaces, using the selected microcontroller and development environment.
Application logic
Implement product behaviour, communication flows and control functions around the project requirements.
Debugging & handover
Investigate integration issues, review functional behaviour and prepare the agreed source code and build documentation.
WHAT YOU TAKE FORWARD
Typical deliverables
- Firmware source for the agreed features
- Build and programming instructions
- Interface descriptions and configuration notes
- Functional test notes and known limitations
- Release identification and handover documentation
Illustrative deliverables. Final outputs, file formats, ownership terms and acceptance criteria are agreed in the project scope.
WHAT HELPS US START
Information to share
- Target microcontroller or development board
- Schematic, pin assignments and peripheral details
- Expected behaviour, operating modes and fault cases
- Communication requirements and message definitions
- Existing source code and toolchain, if applicable
DESIGN CONSIDERATIONS
Engineering considerations
Behaviour
Startup, operating states, invalid inputs and recovery expectations.
Interfaces
Pin configuration, peripheral timing and communication contracts.
Maintainability
Build reproducibility, configuration, readable structure and release notes.
SERVICE QUESTIONS
Frequently asked questions
Can you improve existing firmware?
Existing-source review, debugging and feature work can be scoped after reviewing access to the source, build environment and target hardware.
Which microcontroller should we use?
The choice depends on interfaces, memory, timing, power and supply constraints. Share the requirements so platform selection can be part of the technical discussion.
Is source code included?
Source and handover requirements are agreed in the project scope. Third-party components remain subject to their own licences and access conditions.
