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.

Inits/ILI9486.cpp@11:b842b8e332cb, 2015-02-20 (annotated)

Revision:
11:b842b8e332cb
Parent:
10:668cf78ff93a 
added auto_gram_read_format() to TFt inits. Even if write is set to 16bit RGB color, for some controllers the read cmd outputs 18bit BGR. Now that function will autodetect and set internal flags accordingly, so pixelread() is always correct.
