jernej_vrscaj 0:d96e7e513c16 5 * A common base class for Text displays
jernej_vrscaj 0:d96e7e513c16 6 * To port a new display, derive from this class and implement
jernej_vrscaj 0:d96e7e513c16 7 * the constructor (setup the display), character (put a character
jernej_vrscaj 0:d96e7e513c16 8 * at a location), rows and columns (number of rows/cols) functions.
jernej_vrscaj 0:d96e7e513c16 9 * Everything else (locate, printf, putc, cls) will come for free
jernej_vrscaj 0:d96e7e513c16 10 *
jernej_vrscaj 0:d96e7e513c16 11 * The model is the display will wrap at the right and bottom, so you can
jernej_vrscaj 0:d96e7e513c16 12 * keep writing and will always get valid characters. The location is
jernej_vrscaj 0:d96e7e513c16 13 * maintained internally to the class to make this easy
