• The module doesn't buffer the screen (it wouldn't fit in memory) - so it has to ask the display for the color of a pixel. But no code to do that is present in the module.

    See the module - it has fillRect and setPixel (which I figure must be called in turn by other methods of Graphics), but no getPixel. http://www.espruino.com/modules/ILI9341.­js

    setColor and getColor don't involve any communication with the display.
