Built-in Drivers

Renesas is an official partner of LVGL. Therefore, LVGL contains built-in support for Dave2D (the GPU of Renesas) and we also maintain ready-to-use Renesas projects.

Dave2D

Dave2D is capable of accelerating most of the drawing operations of LVGL:

  • Rectangle drawing, even with gradients

  • Image drawing, scaling, and rotation

  • Letter drawing

  • Triangle drawing

  • Line drawing

As Dave2D works in the background, the CPU is free for other tasks. In practice, during rendering, Dave2D can reduce the CPU usage by half or to one-third, depending on the application.

GLCDC

GLCDC is a multi-stage graphics output peripheral available in several Renesas MCUs. It is able to drive LCD panels via a highly configurable RGB interface.

More info can be found at the driver's page.

MPU Drivers

Renesas MPUs (i.e., the RZ/G family) can use LVGL MPU drivers.

Wayland

Supported on boards with a Wayland desktop AKA a Wayland compositor.

fbdev

Almost always available.
