dreschpe 0:4bbc531be6e2 5 * A common base class for Text displays
dreschpe 0:4bbc531be6e2 6 * To port a new display, derive from this class and implement
dreschpe 0:4bbc531be6e2 7 * the constructor (setup the display), character (put a character
dreschpe 0:4bbc531be6e2 8 * at a location), rows and columns (number of rows/cols) functions.
dreschpe 0:4bbc531be6e2 9 * Everything else (locate, printf, putc, cls) will come for free
dreschpe 0:4bbc531be6e2 10 *
dreschpe 0:4bbc531be6e2 11 * The model is the display will wrap at the right and bottom, so you can
dreschpe 0:4bbc531be6e2 12 * keep writing and will always get valid characters. The location is
dreschpe 0:4bbc531be6e2 13 * maintained internally to the class to make this easy
