June 2026 monthly summary focusing on codebase hygiene and configuration cleanup in zephyrproject-rtos/zephyr. Primary deliverable: removal of an unnecessary debug configuration file that was merged by mistake, in the samples/drivers area, streamlining configuration surfaces and reducing potential confusion. This work improves maintainability, reduces build-time risk, and supports faster onboarding for new contributors.

Month: 2026-05 — Governance enhancement for the DALI driver in the Zephyr project. Delivered a dedicated Maintainer Area to indicate support status and enable project-level management, and nominated Sven Haedrich as maintainer. This creates clear ownership, streamlined contribution workflow, and improved release readiness for DALI-related work. The change is captured in the commit: bb1b70a01a3a6d57d7266c1f8bc9ead49d89bbda.

September 2025: Delivered a complete DALI support package for Zephyr (IEC 62386 compliant): a generic DALI driver API, a PWM-based MCU driver, and a sample application. This work creates a reusable, standards-aligned interface, enabling faster integration with DALI lighting systems and broader MCU support. Validated on STM32F091 and nRF52840 with Zephyr PWM/GPIO/timer bindings. Business value includes accelerated feature delivery, safer integration, and a solid platform for future DALI ecosystem expansion.
