During a three-month period, Michael David enhanced robotics and embedded systems software across multiple repositories. He developed per-axis trajectory control in C++ for Auterion/px4-ros2-interface-lib, introducing a builder-pattern TrajectorySetpoint structure to improve API flexibility for ROS 2 integrations. In tiiuae/nuttx and PX4/NuttX, he expanded Ethernet hardware compatibility by enabling operation without MDIO/MDC lines, using device driver and hardware configuration skills to streamline deployments on STM32H7 platforms. Michael also resolved a UI synchronization race in mavlink/qgroundcontrol, applying embedded systems and UI development expertise to ensure accurate flight mode display during asynchronous state transitions.
Oct 2025: Fixed a UI flight mode name synchronization race in mavlink/qgroundcontrol to ensure the UI always shows the correct human-readable flight mode name, even if the HEARTBEAT arrives before the mode mapping is fully processed. The change re-emits the flight mode change after the available modes are updated, eliminating stale names on first display after mode updates. Delivered with a targeted commit that updates the UI after receiving available modes.

April 2025: Expanded Ethernet hardware compatibility by removing mandatory MDIO/MDC lines through config-driven features and backported NO_PHY support across Nuttx and PX4/NuttX. These changes enable Ethernet operation in hardware setups lacking MDIO/MDC connections, streamline deployments, and improve portability across STM32H7 platforms.

Month: 2025-03 — Focused on delivering API improvements for Auterion/px4-ros2-interface-lib with a new per-axis trajectory control capability and enhanced builder-based TrajectorySetpoint. No major bugs fixed this month. The changes enable more precise, per-axis control (position, velocity, acceleration, yaw, yaw rate) and improve API flexibility for downstream ROS2 integrations.
