This is a follow up to a post I made here.
The documentation for Displays states that it is possible to send output to two displays (physical displays.)
I’m creating an app that represents dashboards. While I can create different screens and link them to displays, that is not my goal. I’m hoping to create Dashboard A that is always shown on Display 1 and can be updated. At the same time in the same app, I would like Dashboard B to always be shown on Display2 and be continuously updated.
I think I would need to modify
fbdev to expose and register my second framebuffer. I wrote some ugly code to do that and it worked.
What I’m hoping the community has is an example of how to implement multiple displays. I’ve searched but I’ve found nothing that I understand on how to address 2 different displays with lvgl.
