PROFILE
Henrychen160905
Contributed to the embedded-purdue/slayterHIL repository by developing and integrating key features for an embedded flight controller over a three-month period. Delivered protobuf-based messaging to enable serialized inter-module communication and restored core controller functionality for reliable mission-critical operations. Integrated the Garmin LIDAR-Lite V4 sensor, implementing I2C driver development and device overlays to provide distance measurement and obstacle detection. Improved build hygiene by removing unused debug artifacts and ensured compatibility with Zephyr RTOS through dependency and kernel header updates. Demonstrated expertise in C and C++ programming, embedded systems, and hardware integration, with a focus on maintainable, high-quality code and robust sensor interfacing.

Nov 1, 2025Month: 2025-11 | Repository: embedded-purdue/slayterHIL Key features delivered: - Garmin LIDAR-Lite V4 sensor integration: added driver, I2C configuration, data fetching, and device overlay support to enable distance measurement in the flight controller. Refinements included polling rate adjustments to 33 Hz and overlay stability improvements. Commit trail includes: flashed lidar driver; read driver working with 33 Hz polling; added GPIO trigger/monitor definitions; restored original overlay. Major bugs fixed / quality improvements: - Protobuf compatibility: updated Zephyr revision and enabled kernel headers to ensure protobuf compatibility in the main module. Commit: Update dependencies for protobuf compatibility. - Flight controller build cleanliness: removed unused debug artifacts to streamline builds and reduce project clutter. Commit: Remove debug artifacts. Overall impact and accomplishments: - Enabled reliable distance sensing for the flight controller, expanding sensing capabilities and enabling new use-cases and safer flight operations. - Improved system reliability and maintainability through protobuf compatibility, as well as a leaner, faster build process. - Demonstrated end-to-end hardware-software integration skills: driver development, device overlays, and cross-module protobuf alignment. Technologies and skills demonstrated: - Embedded systems programming, I2C driver development, and GPIO overlay configuration (Garmin LIDAR-Lite V4). - Zephyr OS integration, kernel header enablement, and protobuf compatibility work. - Build hygiene and artifact cleanup to accelerate iteration.
