= Extending the WARPLab Reference Design =

The WARPLab Reference Design is intended to be modified and extended to support new applications. Because of the object-oriented design of the framework, users may add extensions to the reference design and maintain those extensions across new releases of WARPLab with minimal compatibility problems.

== Simple Extensions: Adding New Commands with User Extension Objects ==

Simple extensions are inherently supported by the WARPLab Framework's [wiki:../Framework/Modules#UserExtension User Extension module]. A user can create their own user extension class that knows how to deal with custom WARPLab commands. Custom user extension classes should inherit from the [source:ResearchApps/PHY/WARPLAB/WARPLab7/M_Code_Reference/classes/wl_user_ext.m wl_user_ext] class and overload the [source:ResearchApps/PHY/WARPLAB/WARPLab7/M_Code_Reference/classes/wl_user_ext.m#L11 procCmd] method. Furthermore, users should update the hardware and software design that runs on the WARP boards to handle their custom commands. For an example of how to use the user extension module, please see the [wiki:../Examples/userExtension EEPROM User Extension] example.
