2018US_HarisSoljic 0:b8956708b92f 5 * A common base class for Text displays
2018US_HarisSoljic 0:b8956708b92f 6 * To port a new display, derive from this class and implement
2018US_HarisSoljic 0:b8956708b92f 7 * the constructor (setup the display), character (put a character
2018US_HarisSoljic 0:b8956708b92f 8 * at a location), rows and columns (number of rows/cols) functions.
2018US_HarisSoljic 0:b8956708b92f 9 * Everything else (locate, printf, putc, cls) will come for free
2018US_HarisSoljic 0:b8956708b92f 10 *
2018US_HarisSoljic 0:b8956708b92f 11 * The model is the display will wrap at the right and bottom, so you can
2018US_HarisSoljic 0:b8956708b92f 12 * keep writing and will always get valid characters. The location is
2018US_HarisSoljic 0:b8956708b92f 13 * maintained internally to the class to make this easy
