Worked on the qmk/qmk_firmware repository to deliver a targeted bug fix for the boardsource/unicorne keyboard, focusing on embedded systems and firmware development using C. Addressed a critical issue with RGB LED matrix coordinate alignment, ensuring that LEDs now map accurately to their intended positions within the keyboard matrix. The solution involved validating the impact within the existing matrix coordinate computation path and collaborating with maintainers to implement robust regression protection. Enhanced test and verification coverage for LED matrix mapping, which streamlines future debugging and improves reliability for hardware-led features across various configurations. No new features were introduced during this period.
