Here you will find a number of different application examples for the RTCU units.

All examples are complete, and gives an excellent view of how simple and easy it is to develop specific solutions on an RTCU unit. The samples here are installed if you download and install the RTCU-IDE program. You can then test the samples in the built-in simulator, or upload the projects to a RTCU unit.

A good place to start is the Tutorial section in the online help.
The Online Help system of the RTCU-IDE program can be accessed here (please note that the formatting of the text may be incorrect due to the conversion to HTML).
