# Partial Update Partial update moving square example for Soldered Inkplate 4 using LVGL. ## Overview Demonstrates partial update mode by moving a square across the screen. Only the changed regions are refreshed, making updates faster than a full display refresh. ## Hardware Required - Soldered Inkplate 4 - USB cable ## Setup Run `idf.py menuconfig` and navigate to: **Inkplate Boards → Inkplate4** ## Build and Flash ``` idf.py build idf.py -p PORT flash monitor ``` ## Expected Output A square moves diagonally across the screen using partial updates. ## Notes - `LV_DISPLAY_RENDER_MODE_PARTIAL` enables partial refresh; only changed regions are sent to the panel. - `display.partialUpdate()` pushes the dirty region to the e-paper panel. ## Resources - Docs: https://docs.soldered.com/inkplate - Support: https://forum.soldered.com/ - Image tool: https://tools.soldered.com/tools/image-converter/
