EMBEDDED SOFTWARE THAT REMAINS AN ASSET
Production-grade firmware built for reliable products and future change
Reduce debugging time, product risk and dependence on individual developers with firmware that is architected, tested, documented and released as a maintainable part of the product.
ABTC develops new embedded platforms, recovers inherited codebases and strengthens prototype software for production. We connect low-level drivers, RTOS behaviour, communications, diagnostics, updates and product logic to the real hardware and lifecycle.
CLIENT OUTCOMES
Firmware quality expressed as product value
Good embedded software is visible in reliable behaviour, controlled releases, recoverable failures and the speed with which a team can understand and evolve the device.
Architecture that contains complexity
Separate hardware access, drivers, services, communications and application behaviour through clear interfaces and ownership.
Evidence before release
Use reviews, static analysis, automated builds, unit or integration tests and hardware validation appropriate to product risk.
Diagnostics that shorten field problems
Design logs, status, fault handling, recovery and service information so failures can be investigated rather than guessed.
Secure and controlled evolution
Prepare boot, update, configuration, compatibility and release processes that support product variants and long service lives.
WHEN WE ADD THE MOST VALUE
From first firmware architecture to difficult codebase recovery
We add the most value when embedded software affects hardware integration, wireless performance, power, safety, maintainability or the ability to deliver future releases.
- New products requiring a clean firmware and RTOS architecture.
- Prototype code that works but cannot be tested, maintained or safely extended.
- Inherited C or C++ codebases with intermittent faults or unclear ownership.
- Products needing BLE, Wi-Fi, UWB, TCP/IP, MQTT or custom communications.
- Devices requiring bootloaders, secure update, diagnostics or long-term maintenance.
A CONTROLLED ENGINEERING PATH
Make behaviour, risks and releases observable
Understand the product and code
Review hardware, requirements, repository, build system, runtime constraints, faults, interfaces and release expectations.
Define the architecture and evidence
Agree responsibilities, state and data flows, coding rules, test levels, diagnostics, update strategy and acceptance criteria.
Implement in controlled increments
Develop drivers and features with reviews, reproducible builds, test evidence and direct validation on target hardware.
Release for continued ownership
Provide source, configuration, documentation, known limitations, version information and a clear basis for subsequent maintenance.
TANGIBLE PROGRESS
A firmware package another engineer can build, inspect and extend
The deliverable is more than source code. It includes the information and controls needed to reproduce behaviour and continue development.
- Firmware architecture and module responsibilities
- Embedded C or C++ source with agreed coding practices
- Drivers, HAL, middleware, services and application logic
- Build configuration, dependency and release information
- Tests, static-analysis findings and target-hardware evidence
- Doxygen or equivalent technical documentation and handover
DECISION SUPPORT
Evaluating embedded firmware support
Can ABTC improve an existing firmware codebase without rewriting everything?
Yes. We first identify valuable working assets, critical risks and architectural constraints. Refactoring, containment, testing and selective replacement are considered before a full rewrite.
Which RTOS and microcontrollers do you support?
ABTC has substantial experience with Zephyr, FreeRTOS and bare metal across Nordic, NXP, ST and other platforms. Selection is based on requirements, ecosystem, risk, lifecycle and team needs.
Do you apply MISRA-C to every project?
Coding standards and analysis depth are agreed according to product risk, sector and commercial needs. MISRA-C and BARR-C practices can strengthen consistency and safety, but the verification plan must match the actual product.
Can you develop firmware while another supplier designs the hardware?
Yes. We define interfaces, review schematics and bring-up requirements, and maintain a direct technical loop with the hardware team. Earlier collaboration reduces driver and integration surprises.
Turn firmware into a durable part of the product
Share the repository, architecture, hardware or behaviour that needs to improve. We will identify the first engineering step that reduces risk and creates measurable progress.
