Fork of DMBasicGUI by Embedded Artists

SlideShow/AppSlideShow.cpp@17:6e2abf107800, 2015-03-20 (annotated)

Committer:

Date:

Revision:
17:6e2abf107800
Parent:
15:a68bb30ab95e 
- Added a Resource concept to allow runtime selection of image source. The

  resource can be loaded from an array in flash or from a file on any of the

  available file systems. Using a resource makes it possible to have different

  resources depending on display resolution

- Removed the basic_image data files

- Added support for the 5" display (800x480 resolution)

- Added possibility to change the default font in SWIM
