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
