Sissors 0:ab0aec01b38e 5 * A common base class for Text displays
Sissors 0:ab0aec01b38e 6 * To port a new display, derive from this class and implement
Sissors 0:ab0aec01b38e 7 * the constructor (setup the display), character (put a character
Sissors 0:ab0aec01b38e 8 * at a location), rows and columns (number of rows/cols) functions.
Sissors 0:ab0aec01b38e 9 * Everything else (locate, printf, putc, cls) will come for free
Sissors 0:ab0aec01b38e 10 *
Sissors 0:ab0aec01b38e 11 * The model is the display will wrap at the right and bottom, so you can
Sissors 0:ab0aec01b38e 12 * keep writing and will always get valid characters. The location is
Sissors 0:ab0aec01b38e 13 * maintained internally to the class to make this easy
