LVGL as it is now on NuttX indeed uses this "frambuffer character driver to LCD interface" but I really dislike this, it is an unnecessary confusion of interfaces. The character driver I wrote is a very simple mapping of LCD interface to userspace without performance penalty and clear semantics. LVGL can use whatever you want. See how I implemented the interface myself: https://gitlab.com/bicycle-companion/firmware/-/blob/master/extra_apps/bicycle_companion/display.cxx#L93 Yes, what I'm talking about does not impact NX in anyway. I was actually suggesting Brennan that he could try LVGL for this if he wanted, and how it could be made faster with this interface than with the framebuffer -> LCD interface. As per improving NX, I'm personally more vested in LVGL for my use cases so I cannot comment. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
