king33jp 0:65f206d9f71f 5 * A common base class for Text displays
king33jp 0:65f206d9f71f 6 * To port a new display, derive from this class and implement
king33jp 0:65f206d9f71f 7 * the constructor (setup the display), character (put a character
king33jp 0:65f206d9f71f 8 * at a location), rows and columns (number of rows/cols) functions.
king33jp 0:65f206d9f71f 9 * Everything else (locate, printf, putc, cls) will come for free
king33jp 0:65f206d9f71f 10 *
king33jp 0:65f206d9f71f 11 * The model is the display will wrap at the right and bottom, so you can
king33jp 0:65f206d9f71f 12 * keep writing and will always get valid characters. The location is
king33jp 0:65f206d9f71f 13 * maintained internally to the class to make this easy
