RTLI Example 2
The RTLI example shows an interpretive RTLI can be used to drive a real-time system within its deterministic requirements yet sill allow for quick modification of the human-computer interface. The example also shows how a FIFO can be used to connect an interpretive real-time application with the real-time module. FIFOs are often used to connect a non-real-time human-computer interface to a real-time application, or for data logging to a storage device. The experimental example allows users to acquire real-time data from a National Instruments DIO96 board at a rate of 10kHz.

This example requires the following:
      RTAI should be installed and a RTAI patched kernel should be running.
      A web server should be installed along with Ch CGI.
      Ch GTK+ and Ch Magick must be installed for the 'GTK_RTLI.cpp' application to work.

Files used in the example: (Click on the file name to view the file online)

console_rtli.ch :	Source code for the command line version of the real-time application.
control.h :	Header file containing shared variable names.
DIO96.h :	Header file containing NI DIO96 variable names.
gtk_rtli.cpp :	Source code for the gui version of the real-time application. Ch GTK+ and Ch Magick must be installed for this application to work.
Makefile:	Makefile used to build the real-time task module and real-time test application.
rt_task.c:	Source code for the real-time task.
rt_task_test.c:	Testing application to make sure that the real-time task and the NI DIO96 are working.
web_rtli.ch:	Ch CGI code for Web-based control.
index.html:        rtli.html:        form.html:	Website HTML for the Web-based control interface.
