Demo for Embedded World 2015.

Dependencies:   DMBasicGUI DMSupport

Demo running on several LPC4088 Display Modules on the Embedded World 2015 exhibition.

Information

To run the demo first drag-n-drop the to_sync.fs3 file to the MBED drive and then drag-n-drop the demo itself. This way both the file system and software are up to date.

This is what the launcher will look like:

/**
 * An App example. Searches for images on any connected media (USB Mass Storage, 
 * SD Card or QSPI File System) and presents the images one at a time, scaled to
 * fit the display.
 *
 * The purpose of this example is to show how to recursively search the file
 * systems and how to load images. The image scaling could be replaced with 
 * rotating, cropping or any other image operation. The two second delay between
 * images could be replaced with buttons or other touch events.
