Wizo 0:a4839c6a1bf5 5 * A common base class for Text displays
Wizo 0:a4839c6a1bf5 6 * To port a new display, derive from this class and implement
Wizo 0:a4839c6a1bf5 7 * the constructor (setup the display), character (put a character
Wizo 0:a4839c6a1bf5 8 * at a location), rows and columns (number of rows/cols) functions.
Wizo 0:a4839c6a1bf5 9 * Everything else (locate, printf, putc, cls) will come for free
Wizo 0:a4839c6a1bf5 10 *
Wizo 0:a4839c6a1bf5 11 * The model is the display will wrap at the right and bottom, so you can
Wizo 0:a4839c6a1bf5 12 * keep writing and will always get valid characters. The location is
Wizo 0:a4839c6a1bf5 13 * maintained internally to the class to make this easy
