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:
