gmehmet 0:0d4feb02e324 5 * A common base class for Text displays
gmehmet 0:0d4feb02e324 6 * To port a new display, derive from this class and implement
gmehmet 0:0d4feb02e324 7 * the constructor (setup the display), character (put a character
gmehmet 0:0d4feb02e324 8 * at a location), rows and columns (number of rows/cols) functions.
gmehmet 0:0d4feb02e324 9 * Everything else (locate, printf, putc, cls) will come for free
gmehmet 0:0d4feb02e324 10 *
gmehmet 0:0d4feb02e324 11 * The model is the display will wrap at the right and bottom, so you can
gmehmet 0:0d4feb02e324 12 * keep writing and will always get valid characters. The location is
gmehmet 0:0d4feb02e324 13 * maintained internally to the class to make this easy
