masato 0:c99dda90f834 5 * A common base class for Text displays
masato 0:c99dda90f834 6 * To port a new display, derive from this class and implement
masato 0:c99dda90f834 7 * the constructor (setup the display), character (put a character
masato 0:c99dda90f834 8 * at a location), rows and columns (number of rows/cols) functions.
masato 0:c99dda90f834 9 * Everything else (locate, printf, putc, cls) will come for free
masato 0:c99dda90f834 10 *
masato 0:c99dda90f834 11 * The model is the display will wrap at the right and bottom, so you can
masato 0:c99dda90f834 12 * keep writing and will always get valid characters. The location is
masato 0:c99dda90f834 13 * maintained internally to the class to make this easy
