Worked on the lvgl/lvgl repository, focusing on enhancing the maintainability of the lv_canvas_copy_buf API through targeted code refactoring. Applied expertise in C programming and API design to clarify parameter names, reducing ambiguity and aligning with established naming conventions. This approach improved code readability and supported future development by making the API easier to understand for both current and new contributors. Updated documentation and inline comments to reflect the refined parameter semantics, helping prevent misuse and lowering the cognitive load for developers. The work emphasized long-term code quality and stability, with no major bug fixes completed during this period.
