:name: LVGL Multi-display
|
|
:relevant-api: display_interface
|
|
|
|
Run different LVGL demos on multiple displays.
|
|
|
|
Overview
|
|
********
|
|
|
|
A sample showcasing LVGL multi-display support in Zephyr.
|
|
|
|
By default, it runs the Music demo on the first display, and the Widgets demo on the other ones
|
|
(order as defined in the "displays" property of "zephyr,displays" compatible node in deviceTree).
|
|
Which demos are run can be changed by modifying the value of CONFIG_LV_Z_DEMO_FIRST_DISP## and
|
|
CONFIG_LV_Z_DEMO_OTHER_DISPS## Kconfig symbols.
|
|
|
|
* Music
|
|
The music player demo shows what kind of modern, smartphone-like user interfaces can be
|
|
created on LVGL.
|
|
* Benchmark
|
|
The benchmark demo tests the performance in various cases. For example rectangle, border,
|
|
shadow, text, image blending, image transformation, blending modes, etc.
|
|
* Stress
|
|
A stress test for LVGL. It contains a lot of object creation, deletion, animations, styles
|
|
usage, and so on. It can be used if there is any memory corruption during heavy usage or any
|
|
memory leaks.
|
|
* Widgets
|
|
Shows how the widgets look like out of the box using the built-in material theme.
|
|
|
|
More details on the demos can be found in `LVGL demos Readme`_.
