接口两种模式，以下是DATASHEET原文，Raster模式就是RGB模式，LIDD就是8080。
• The Raster Controller handles the synchronous LCD interface. It provides timing and data for constant
graphics refresh to a passive display. It supports a wide variety of monochrome and full-color display
types and sizes by use of programmable timing controls, a built-in palette, and a gray-scale/serializer.
Graphics data is processed and stored in frame buffers. A frame buffer is a contiguous memory block
in the system. A built-in DMA engine supplies the graphics data to the Raster engine which, in turn,
outputs to the external LCD device.
• The LIDD Controller supports the asynchronous LCD interface. It provides full-timing programmability
of control signals (CS, WE, OE, ALE) and output data.
我现在想接一个DE模式的屏，AM335X只有HSYNC和VSYNC脚，不晓得怎么搞啊。 |
