Porting and Hands-On Guide for LVGL 8.2 on the OK3568-C Platform under Linux 4.19 Buildroot
LVGL (Light and Versatile Graphics Library) is a lightweight, open-source graphics library purpose-built for embedded systems. Written in C, it boasts minimal resource requirements (as little as 64 KB Flash and 16 KB RAM) and cross-platform portability, supporting microcontrollers such as STM32 and ESP32 as well as operating systems like FreeRTOS and Linux 12. The library ships with 30+ ready-made UI widgets—buttons, charts, lists—and advanced graphical effects including animations and anti-aliasing. It handles multi-input devices (touchscreens, keyboards, etc.) and leverages a hardware-abstraction layer for efficient rendering 12. Thanks to its modular architecture, LVGL can be deeply customized and is widely adopted in smart-home appliances, industrial HMIs, medical devices, and more.
This guide walks you through porting LVGL 8.2 to the OK3568-C board running Linux 4.19.206 built with Buildroot.
