Worked on stabilizing the NuttX driver within the lvgl/lvgl repository, focusing on low-level graphics improvements for embedded systems. Addressed a critical issue in C by correcting the stride calculation for indexed color formats with one bit per pixel, which previously led to draw buffer mis-sizing and potential display corruption on low-color-depth devices. The solution involved precise driver development and low-level programming to ensure accurate data pointer handling and reliable rendering. This targeted fix improved the robustness of graphics output in constrained environments, demonstrating careful attention to detail and a strong grasp of embedded systems challenges in real-world device contexts.
