igbt6 0:619824763516 5 * A common base class for Text displays
igbt6 0:619824763516 6 * To port a new display, derive from this class and implement
igbt6 0:619824763516 7 * the constructor (setup the display), character (put a character
igbt6 0:619824763516 8 * at a location), rows and columns (number of rows/cols) functions.
igbt6 0:619824763516 9 * Everything else (locate, printf, putc, cls) will come for free
igbt6 0:619824763516 10 *
igbt6 0:619824763516 11 * The model is the display will wrap at the right and bottom, so you can
igbt6 0:619824763516 12 * keep writing and will always get valid characters. The location is
igbt6 0:619824763516 13 * maintained internally to the class to make this easy
