A structured checklist for bringing up an embedded display before or during LVGL integration.
The checklist focuses on observable evidence and separates electrical, controller, transport, framebuffer, LVGL, input, and performance problems.
- Confirm power, reset, clocks, and physical connections.
- Prove basic controller communication without LVGL.
- Draw known solid colors and test patterns.
- Confirm resolution, orientation, color order, and pixel format.
- Integrate the LVGL display driver and flush callback.
- Integrate input devices and coordinate mapping.
- Measure memory, update time, and interaction performance.
- Save evidence and known-good configuration values.
Use checklists/display-bringup.md as the project record.
This resource is applicable to common MCU-based projects using SPI, parallel/RGB, or similar display transports. Controller names such as ST7789 are examples; always follow the selected panel and controller documentation.
PanelSprint provides independent LVGL UI implementation and integration support for STM32, ESP32, FreeRTOS, and other embedded targets.
