Wim Huiskamp / Mbed 2 deprecated TextLCD_HelloWorld2

Hello World demo for Enhanced TextLCD lib.

Dependencies:   TextLCD mbed

Dependents:   Opener-6

The Enhanced TextLCD lib supports more display types than the original lib. Added support for User Defined Characters (UDCs), Backlight control and other features such as control through I2C and SPI port expanders and controllers with native I2C and SPI interfaces. See here for more info.
