| be_bryan | 0:b74591d5ab33 | 5 | * A common base class for Text displays |
| be_bryan | 0:b74591d5ab33 | 6 | * To port a new display, derive from this class and implement |
| be_bryan | 0:b74591d5ab33 | 7 | * the constructor (setup the display), character (put a character |
| be_bryan | 0:b74591d5ab33 | 8 | * at a location), rows and columns (number of rows/cols) functions. |
| be_bryan | 0:b74591d5ab33 | 9 | * Everything else (locate, printf, putc, cls) will come for free |
| be_bryan | 0:b74591d5ab33 | 10 | * |
| be_bryan | 0:b74591d5ab33 | 11 | * The model is the display will wrap at the right and bottom, so you can |
| be_bryan | 0:b74591d5ab33 | 12 | * keep writing and will always get valid characters. The location is |
| be_bryan | 0:b74591d5ab33 | 13 | * maintained internally to the class to make this easy |
