Kevin Braun / Mbed 2 deprecated TFTdisp-104

A general demonstration color etch-a-sketch program using the QVGA TFT with HX8347D controller, Orange Board. Saves touchscreen calibaration data saved in tft.ini. Creates /local/tft.ini if missing. Also included is an Ethernet NTP client to update the RTC. Assumes all other Orange Board devices attached: Text LCD, SDHC Flash, Ethernet.

Dependencies:   EthernetNetIf TextLCD mbed

loopsva 0:e065ca40f28a 5 * A common base class for Text displays
loopsva 0:e065ca40f28a 6 * To port a new display, derive from this class and implement
loopsva 0:e065ca40f28a 7 * the constructor (setup the display), character (put a character
loopsva 0:e065ca40f28a 8 * at a location), rows and columns (number of rows/cols) functions.
loopsva 0:e065ca40f28a 9 * Everything else (locate, printf, putc, cls) will come for free
loopsva 0:e065ca40f28a 10 *
loopsva 0:e065ca40f28a 11 * The model is the display will wrap at the right and bottom, so you can
loopsva 0:e065ca40f28a 12 * keep writing and will always get valid characters. The location is
loopsva 0:e065ca40f28a 13 * maintained internally to the class to make this easy
