Duncan Wood / 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.

Dependents:   Brew

Inits/ILI932x.cpp@21:ae0a4eedfc90, 2015-03-31 (annotated)
