LVGL: A versatile UI toolkit for MCU & CPU
summary
LVGL is an MIT‑licensed C graphics library that scales from tiny MCUs to desktops and claims 60 fps on iMXRT1050 with 30% CPU on a 480×272 UI; it provides buttons, charts, text input, CSS‑like styling, UTF‑8/i18n and a MicroPython binding. Backends include SDL2 and Wayland, and the project upstreams Yocto/bitbake recipes. Demonstrations include a vending‑machine on Raspberry Pi and Zephyr keypad; SquareLine Studio (proprietary) is offered as a drag‑and‑drop editor.
