readme.md

eblocha's GMMK Pro layout

Default, with changes:

• moved rgb toggle to Fn+Esc
• moved PrtSc to Fn+F12
• moved Del to default PrtSc
• moved Home to default Del
• enabled rgb key press effects
• Using DEBOUNCE_TYPE = asym_eager_defer_pk
  • see https://www.reddit.com/r/glorious/comments/qidnto/the_best_way_to_fix_gmmk_pro_input_latency_with/
• Set DEBOUNCE to 8ms per recommendation in Reddit thread

    // this mapping, you have to open the case to hit the button on the bottom of the PCB (near the USB cable attachment) while plugging in the USB
    // cable to get the board into bootloader mode - definitely not fun when you're working on your QMK builds. Remove this and put it back to KC_RGUI
    // if that's your preference.
    //
    // To put the keyboard in bootloader mode, use FN+backslash. If you accidentally put it into bootloader, you can just unplug the USB cable and
    // it'll be back to normal when you plug it back in.

    // This keyboard defaults to 6KRO instead of NKRO for compatibility reasons (some KVMs and BIOSes are incompatible with NKRO).
    // Since this is, among other things, a "gaming" keyboard, a key combination to enable NKRO on the fly is provided for convenience.
    // Press Fn+N to toggle between 6KRO and NKRO. This setting is persisted to the EEPROM and thus persists between restarts.
