Summary

There is a simple graphical display interface now available for use with the LUTEar library. It is written using the public domain WxWin cross platform GUI library. Once the library has been compiled with GUI support the Display_Signal module can be accessed using generic or hard programming. The GUI support must be compiled using C++ and the WxWin library. WxWin can be used under X-windows (MOTIF or xview), PC Windows (3.1, 3.11, NT or '95) and there is also a Macintosh version (though this is not currently as advanced as for the other platforms). The Macintosh version does work for the simple commands corrently used for the LUTEar GUI support. See the URL "http://www.aiai.ed.ac.uk/~jacs/wxwin.html" for further information about WxWin. See the INSTALL file for information on installing LUTEar with graphical support. A program which uses the display module can still be compiled using a CRL library which does not have the graphics support included. In such a case the display module will be ignored.

The display module may be included in-line in a process pipeline in the same way that other process modules are used. However, it does not change the input signal passed to it at all, and it points it's output signal directly to the input signal. This means that, used in a simulation, the display module is transparent. In hard programming mode the "Display_Signal(...)" routine can be used to graphically examine the output from any particular EarObject's output signal by giving that EarObject's name as an argument to the routine.
