PROFILE
Eileen Yoon
Eyn contributed to the PurdueElectricRacing/firmware repository by developing and refining embedded systems features for data acquisition, dashboard reliability, and CAN bus integration. Over eight months, Eyn implemented FreeRTOS-based multi-threading, modularized CAN configuration using JSON, and enhanced build systems with CMake and GCC toolchain improvements. Their work included optimizing GPIO and SPI communication in C, introducing a robust bootloader with CRC validation, and establishing scalable onboarding and code formatting practices. By focusing on maintainable architecture and cross-platform compatibility, Eyn enabled more reliable firmware updates, streamlined developer onboarding, and laid a strong foundation for future telemetry and real-time control enhancements.

Jul 1, 2025July 2025 performance summary for PurdueElectricRacing/firmware: Delivered cross-platform firmware capabilities, improved build stability, and strengthened developer onboarding to accelerate time-to-market. Implemented automatic PHAL architecture detection across STM32 MCUs with centralized header management, expanded STM32G4 support, and integrated FreeRTOS builds for F4/F7/G4 families, including bootloader linker script adjustments. Added a syscalls shim to silence build warnings and completed build system cleanup to ensure GCC-10 compatibility and reduced noise. Enhanced onboarding and tooling with a dedicated onboarding_26 test template, a placeholder for LED blinking, comprehensive VS Code onboarding guidance, and standardized code formatting via clang-format. Collectively, these efforts shorten development cycles, improve firmware reliability, and demonstrate a mature, scalable engineering workflow.

Jun 1, 2025June 2025 monthly summary for PurdueElectricRacing/firmware. Key accomplishment: CAN Configuration Refactor and Unified Message Priority. The can_config.json was split into node-specific files; introduced a robust abstraction for CAN message priority levels by replacing older fields (msg_hlp and msg_pgn) with a unified msg_priority; removed unused fields (bus_speed, node_ssa, busload estimation) to simplify configuration and reduce maintenance. Impact: improved maintainability, easier onboarding for new nodes, reduced misconfiguration risk, and a scalable foundation for future CAN tuning. No explicit bug fixes were required this month; the refactor reduces risk and stabilizes CAN behavior. Technologies/skills demonstrated: modular configuration management, JSON refactoring, CAN bus architecture, abstraction design, and version control best practices.
