Engineering service
Embedded software development
Build reliable firmware that works with the hardware, supports verification and remains understandable throughout the product lifecycle.

Illustrative engineering concept, not a completed client project.
Where DVAR can help
- Firmware and hardware integration is blocking a working prototype.
- Legacy code needs stabilisation, documentation or a controlled handover.
- Communications, control or device behaviour needs repeatable testing.
Capabilities
- Firmware requirements and architecture
- Device drivers and hardware abstraction
- Industrial and embedded communications
- Control, sensing and actuator integration
- Unit, integration and hardware-in-loop testing
- Documentation, review and technical handover
What you receive
Deliverables are agreed for the project stage and designed for practical review, use and handover.
- Maintainable source code and build instructions
- Interface definitions and technical documentation
- Test specifications and verification evidence
- Integrated firmware ready for product verification
Plan the work around the evidence
Start with what exists and agree what the next development milestone needs to demonstrate.
Share an outline requirement, current design stage and the main constraint. Detailed files can follow through an agreed channel.
Agree the scope, interfaces, deliverables and acceptance criteria before detailed development begins.
Review the design information and test evidence against the agreed requirement, with clear actions for the next stage.
Before you enquire
Can you work with existing firmware?
DVAR supports legacy firmware stabilisation, documentation and controlled handover, as well as new development. An initial review establishes the available source, build process, hardware and evidence of the problem.
How is firmware tested with the hardware?
The test approach can combine unit, integration and hardware-in-loop testing, selected around the product requirements. Interfaces, expected device behaviour and repeatable test conditions are agreed during planning.
What should a firmware handover contain?
Depending on the scope, a handover includes source code, build instructions, interface definitions, technical documentation and verification evidence so the work can be reviewed and maintained.
Start with the next useful decision.
Share the requirement, current evidence and the risk you need to resolve.
