TOOL

The Editor

Draw with pen, shapes, fill and text; add frames for animation; import an image with dithering; or pull an existing OLED array straight out of a .gpc script, edit it, and swap it back in.

FEATURES

What It Does

DRAW

Pen, eraser, line, rectangle, ellipse, circle, triangle, star, fill, text and selection — with undo, redo, invert and clear.

ANIMATE

Multiple frames with duplicate, delete, onion-skin and live playback for scrolling menus and animated splash screens.

IMPORT

Drop in any image with adjustable threshold and dithering, or import an OLED array from an existing .gpc file.

EXPORT

GPC array, full script, Arduino/C, PNG and animation. Copy to clipboard or download — then paste straight into your build.

PROJECTS

Save and load your work locally so a design in progress is always there when you come back to it.

TIP

Round-Trip a Script

The fastest way to restyle an OLED menu you already have:

Open the editor and use Import from .gpc to pull the OLED array out of your script.
Edit the screen — redraw, add frames, or clean up the pixels.
Export and swap the edited array back into the same script — everything else stays intact.
