Corne Supernano ZMK Config

Custom ZMK firmware for a Corne build with:

• animated anime OLED status art on the left half
• connection/layer/key-press status on the right half
• RGB underglow enabled at startup
• an ADJUST lighting layer when LOWER and RAISE are held together
• Japanese input keys on the lower layer

OLED Screens

The OLED firmware is side-specific:

Half	Display
Left	Dancing monochrome anime girl pixel art
Right	Connection status, active layer, last key label, and a tiny key-position grid

The left OLED animation is converted from Dancing Girl Sprites by Luis Zuno / Ansimuz, released as CC0/public domain. The firmware uses the slide dance converted to 1-bit 64x32 frames for the OLED.

This config builds two firmware files. The right half is the main/USB side so its OLED can show connection, layer, and key-label status:

• left keyboard: corne_left.uf2
• right keyboard: corne_right.uf2

OLEDs are 128x32 monochrome, so the anime art is pixel art rather than a full-color image.

RGB Shortcuts

Hold both thumb layer keys:

LOWER + RAISE

Then tap one of these keys:
