LPC18xx/43xx emWin with touch example

Detailed Description

Example description
This example shows how to setup emWin with a simple GUI and use of the touch screen. Prior to building this example, the emWin libraries need to be built.

Special connection requirements
There are no special connection requirements for this example.
