This Repository collects a lot of usefull and mostly not trivial examples that can be used to start a own application.
If you get a "could not find" error when compiling the examples, this could be caused by the directory name change during translation and uploading into this repository. Add the missing file's by hand with the project inspector from the IDE.
Shows the dependencies of the demos to the external libraries (see dependencies how to get to the missing code).
