Detailed Description

Interface for LCD panel displays.

Summary

The display interface provides standard display functionality:

Signal timing configuration for LCD panels with RGB interface.
Dot clock source selection (internal or external) and frequency divider.
Blending of multiple graphics layers on the background screen.
Color correction (brightness/configuration/gamma correction).
Interrupts and callback function.

Implemented by: GLCDC
