mvanendert 1:2b6bdf677573 5 * A common base class for Text displays
mvanendert 1:2b6bdf677573 6 * To port a new display, derive from this class and implement
mvanendert 1:2b6bdf677573 7 * the constructor (setup the display), character (put a character
mvanendert 1:2b6bdf677573 8 * at a location), rows and columns (number of rows/cols) functions.
mvanendert 1:2b6bdf677573 9 * Everything else (locate, printf, putc, cls) will come for free
mvanendert 1:2b6bdf677573 10 *
mvanendert 1:2b6bdf677573 11 * The model is the display will wrap at the right and bottom, so you can
mvanendert 1:2b6bdf677573 12 * keep writing and will always get valid characters. The location is
mvanendert 1:2b6bdf677573 13 * maintained internally to the class to make this easy
