lvgl，lcdifv2，vglite multi layer

[CamillePC]

dear nxp，

I use rt1176, sdk2.12, currently I want to use vglite, lvgl, lcdifv2 to achieve multi-graph layer display. There is no example provided in the routine for lvgl at the multigraph layer. I found out at wpi_group that they have such a scheme. Please provide official help on lvgl multigraph layer. Thank you very much!

To use multiple layers, you only need add a new layer on the plus button

in that way you can add more layers as you want and as your memory board can.

Have a good day

Hi @CamillePC 

What do you mean by "multigraph layer"?, you can use the GuiGuider to make your graphs in lvgl, after that, you can add to MCUXpresso with the example SDK GuiGuider, on youtube can find how to do it

hi,

Your links is not I want. 

I want to use lvgl to implement multiple layers to achieve different refresh rates for different layers. Vglite and lcdifv2 will be used instead of interface switching implemented by lvgl.

I don't know vglite, lcdifv2 and lvgl how to work together.

Can you provide examples of the following links?
