Steven Cooreman 0:a0faa86660d4 5 * A common base class for Text displays
Steven Cooreman 0:a0faa86660d4 6 * To port a new display, derive from this class and implement
Steven Cooreman 0:a0faa86660d4 7 * the constructor (setup the display), character (put a character
Steven Cooreman 0:a0faa86660d4 8 * at a location), rows and columns (number of rows/cols) functions.
Steven Cooreman 0:a0faa86660d4 9 * Everything else (locate, printf, putc, cls) will come for free
Steven Cooreman 0:a0faa86660d4 10 *
Steven Cooreman 0:a0faa86660d4 11 * The model is the display will wrap at the right and bottom, so you can
Steven Cooreman 0:a0faa86660d4 12 * keep writing and will always get valid characters. The location is
Steven Cooreman 0:a0faa86660d4 13 * maintained internally to the class to make this easy
