Developed a robust multi-channel ADC interface for the hytech-racing/VCR repository, enabling accurate measurement from temperature sensors and load cells within an embedded systems context. The work focused on C++ programming and hardware interfacing, emphasizing code safety through API refactoring, clearer method naming, and safer initialization flows. To ensure operational stability during transition, thermistor channels 2-7 were temporarily disabled. The codebase was restructured for maintainability and future scalability, supporting collaborative development and laying groundwork for expanded sensor integration. This effort improved measurement fidelity and prepared the system for scalable sensor support, addressing both immediate functionality and long-term extensibility needs.
