giryan 0:0e729fc7275a 5 * A common base class for Text displays
giryan 0:0e729fc7275a 6 * To port a new display, derive from this class and implement
giryan 0:0e729fc7275a 7 * the constructor (setup the display), character (put a character
giryan 0:0e729fc7275a 8 * at a location), rows and columns (number of rows/cols) functions.
giryan 0:0e729fc7275a 9 * Everything else (locate, printf, putc, cls) will come for free
giryan 0:0e729fc7275a 10 *
giryan 0:0e729fc7275a 11 * The model is the display will wrap at the right and bottom, so you can
giryan 0:0e729fc7275a 12 * keep writing and will always get valid characters. The location is
giryan 0:0e729fc7275a 13 * maintained internally to the class to make this easy
