Jonathan Uhler developed and refined embedded control and signaling systems for the formulaslug/fs-3 and fs-3-schematics repositories over six months, focusing on hardware-software integration and code quality. He implemented brake light signaling and electronic throttle calibration, modernized CAN bus communication, and enhanced sensor interpretation for vehicle subsystems. Using C++, CMake, and KiCad, Jonathan introduced a unit testing framework, standardized code formatting, and improved documentation to streamline onboarding and maintenance. His work included hardware pin reconfiguration, real-time control logic, and calibration routines, resulting in more reliable safety features and maintainable code, with all changes traceable and validated through rigorous testing and documentation.

June 2025 monthly summary for formulaslug/fs-3: Focused on delivering refinement to electronic throttle calibration (HE1/HE2) and improving contributor onboarding. Completed changes aimed at final calibration readiness for vehicle installation and updated project setup docs to clarify Python constraints.

February 2025 monthly summary for formulaslug/fs-3: Delivered key features that improve code quality, testing velocity, and safety reliability. Implemented Unity-based unit testing framework integration and a test infrastructure within the ETC project, with CMake configured to build both the main executable and a dedicated test executable, plus example tests and a reusable test template. Added brake light control logic driven by brake sensor readings and a periodic refresh ticker to keep the brake light status up to date, enhancing safety and reliability. Performed important cleanup by removing a noisy status code print and updating test-related comments to simplify adding tests. These changes collectively reduce regression risk, speed up validation, and demonstrate strong proficiency in build systems, embedded safety features, and test automation.

October 2024: Focused feature integration in the formulaslug/fs-3-schematics repo to enhance brake light signaling. Delivered a Brake Light Signaling System Integration by updating the schematic to incorporate a new LED component, updated power/ground connections, and clear labels (Brake_Signal, Brake_Power, Reverse_Signal). Introduced a control transistor (SSM6N37FU_LF) to operate the brake light circuit as a switch/amplifier, improving reliability and controllability of the signaling path. All changes are traceable to commits for quick rollback and review. Major work for this period consisted of feature delivery rather than bugfixing. Key commits: fbfc747d6a6ff38475d0c7ea235cf6d545c05ec3; c9ea9137f3d6963e6c10c5527c8d46f5870fe3c2.
