Introduction to Zephyr Part 10: Graphics with LVGL and Display Drivers

This 39-minute tutorial demonstrates how to integrate LVGL (Light and Versatile Graphics Library) with the Zephyr real-time operating system to create interactive GUIs on resource-constrained devices. Learn how to set up graphical user interfaces for embedded systems by leveraging LVGL's lightweight, open-source graphics library designed for microcontrollers. Discover how to configure Zephyr to use LVGL and enable the ST7735R SPI display driver through Devicetree. Follow along with practical demonstrations of displaying static and dynamic elements including text labels, counters, and basic shapes like rectangles and circles. The video covers hardware setup, character frame buffer and LVGL overview, analysis of LCD driver and LVGL examples, creating a devicetree overlay for LCD drivers, configuring LVGL in Kconfig, writing application code in C, and running the final demo. Additional resources include a written tutorial, GitHub repository with challenge solutions, and links to official Zephyr documentation. Perfect for developers designing IoT devices, wearables, or industrial equipment with visually appealing interfaces.
