jloreto 0:e67bf8f398ee 5 * A common base class for Text displays
jloreto 0:e67bf8f398ee 6 * To port a new display, derive from this class and implement
jloreto 0:e67bf8f398ee 7 * the constructor (setup the display), character (put a character
jloreto 0:e67bf8f398ee 8 * at a location), rows and columns (number of rows/cols) functions.
jloreto 0:e67bf8f398ee 9 * Everything else (locate, printf, putc, cls) will come for free
jloreto 0:e67bf8f398ee 10 *
jloreto 0:e67bf8f398ee 11 * The model is the display will wrap at the right and bottom, so you can
jloreto 0:e67bf8f398ee 12 * keep writing and will always get valid characters. The location is
jloreto 0:e67bf8f398ee 13 * maintained internally to the class to make this easy
