Production-quality drivers
Drivers are where products get expensive. We deliver maintainable, testable driver support and a clean architecture so your team can move fast without regressions.
Typical deliverables
- Driver implementations with clear interfaces and ownership
- Zephyr drivers from datasheet: flash, I2C, audio, IMU, BLE module, charger, LED strip—including bit-bang and non-standard interfaces when needed
- Test strategy (unit, integration, HIL where relevant)
- Documentation and examples for the rest of the team
- Reviewable changes with a clean history and rationale
In a recent engagement: 8+ production-quality drivers in one month.
What “production-quality” means
- Datasheet- and reference-manual-driven behavior (edge cases, timing, interrupts, DMA, and power states)
- Clean devicetree/Kconfig integration so the driver is configured correctly and predictably
- Robust error handling and recovery paths (so failures are diagnosable, not mysterious)
- A test strategy appropriate for the hardware: unit, integration, and HIL where it pays off
