Worked on the Gaucho-Racing/Firmware repository, focusing on improving the Charging Control Unit (CCU) by clarifying the setSoftwareLatch function’s semantics and updating related documentation. Addressed a bug by renaming parameters and correcting pin logic to better reflect the intended latch state, ensuring the interface is more intuitive for future development. Enhanced maintainability by extending documentation with detailed implementation notes, usage guidelines, and test procedures, all without altering runtime CCU code. Utilized C programming and Markdown to deliver these updates, demonstrating a methodical approach to embedded systems development that prioritizes clarity, risk reduction, and long-term integration stability.
