Worked on enhancing keyboard firmware accuracy for the srwi/qmk_firmware repository by implementing a firmware-level layout alignment for the skiller_sgk50_s4 model. Updated the LAYOUT_all macro to LAYOUT_60_iso, ensuring the firmware’s logical keymap matched the physical keyboard layout. Adjusted both the default and layer 1 keymaps to reflect the actual hardware configuration, improving usability for end users. The work focused on embedded systems and firmware development, utilizing C for precise hardware interaction and keyboard customization. This contribution addressed layout discrepancies, resulting in a more accurate and maintainable firmware base for the targeted keyboard within the QMK ecosystem.
