Hi,
Ive made an open-source graphics editor designed to help create visuals for TFT_eSPI, U8g2, AdafruitGFX, and ESPHome.
Pick the GUI library or platform you're using, choose your display size, and start building with visual tools — draw shapes, add text, and more. As you work, a code window below will auto-generate the source code you can copy into your project to reproduce the design.
You can import your own images and convert them into data arrays. There's also a built-in icon library to help you get started quickly.
Its open source and community-supported: https://github.com/sbrin/lopaka
The cloud version is live at https://lopaka.app
Theres even a gallery of editable screens and UI designs created by others, so you dont have to start from scratch.
I'd love to hear your thoughts:
What do you think of the idea?
What features do you wish it had?
Your feedback is the best motivation to keep building!
