martwerl 0:fb8791842ef8 5 * A common base class for Text displays
martwerl 0:fb8791842ef8 6 * To port a new display, derive from this class and implement
martwerl 0:fb8791842ef8 7 * the constructor (setup the display), character (put a character
martwerl 0:fb8791842ef8 8 * at a location), rows and columns (number of rows/cols) functions.
martwerl 0:fb8791842ef8 9 * Everything else (locate, printf, putc, cls) will come for free
martwerl 0:fb8791842ef8 10 *
martwerl 0:fb8791842ef8 11 * The model is the display will wrap at the right and bottom, so you can
martwerl 0:fb8791842ef8 12 * keep writing and will always get valid characters. The location is
martwerl 0:fb8791842ef8 13 * maintained internally to the class to make this easy
