Detailed Description

Represents a base abstract class for direct draw VGA controller.

A direct draw VGA controller draws paint the screen in real time, for each scanline. Every two scanlines an interrupt is generated. Put your drawing code inside a callback and call setDrawScanlineCallback() to assign it.

See DirectVGA.ino example.

Examples: VGA/DirectVGA/DirectVGA.ino, and VGA/DirectVGA_ElMuro/DirectVGA_ElMuro.ino.
