Component for rendering LVGL.
This component renders LVGL widgets on a display. Some initialisation must be done in the constructor since LVGL needs to be initialised before any widgets can be created.
displays | a list of displays to render onto. All displays must have the same resolution. |
buffer_frac | the fraction of the display resolution to use for the LVGL draw buffer. A higher value will make animations smoother but also increase memory usage. |
full_refresh | if true, the display will be fully refreshed on every frame. If false, only changed areas will be updated. |
draw_rounding | the rounding to use when drawing. A value of 1 will draw without any rounding, a value of 2 will round to the nearest multiple of 2, and so on. |
resume_on_input | if true, this component will resume rendering when the user presses a key or clicks on the screen. |
