Will this library work on RPi CM3+ with or without X?

I'm trying to work on an "embedded" GUI, but Linux and it's framebuffer isn't mentioned in the list of "supported displays", so I'm unsure. Lvgl itself can be run on Raspberry Pi, but I'm wondering what's the status of it in lvgl-rs.

I didn't try to run in Raspberry Pi, but I see no reason why it wouldn't work. As long as you have access to the framebuffer, you can create your own embedded-graphics driver for it. I run lvgl-rs on nRF52832 platform which are way less powerful than a Raspberry Pi.

Oh, so framebuffer driver needs to be implemented before we can use it.
Then that's great news, I'll look into doing that and make it work.
The question wasn't about performance, but about ability to use (linux software) framebuffers and draw onto screens detected by OS and not baremetal.

Thanks!
