La Suno / UniGraphic

Basically i glued Peter Drescher and Simon Ford libs in a GraphicsDisplay class, then derived TFT or LCD class (which inherits Protocols class), then the most derived ones (Inits), which are per-display and are the only part needed to be adapted to diff hw.

Fork of UniGraphic by GraphicsDisplay

UniGraphic for La Suno Version.
To go with La Suno, WatchDog Reset functions were added in ILI9341.
