Since there's been a lot of talk about GUIs and graphical programming, I'll describe some of the work I've been doing. I'm using a graphical modeling tool called Ptolemy to allow design of gnuradio systems.
Here is the basic approach: 1) Automatically scan gnuradio source tree and build XML representations of blocks, including things like constructor parameter lists. These are in Ptolemy's MoML format so Ptolemy can import them. I have written a python program to generate these files. 2) Use Ptolemy to draw block diagrams and connections. Ptolemy allows block parameters to be configured by inspecting the XML I just described. 3) Then have Ptolemy convert the block diagram into a gnuradio python program. Ptolemy is written in Java, so I have written Java classes to do this. 4) Ptolemy launches this program and communicates with it using pipes. This allows you to create other pieces of Ptolemy simulations that source or sink data to GR. Here's a screenshot to give you an idea: http://www.ee.ucla.edu/~tjdreier/gnuradio_ptolemy.jpg It shows a top-level model where GNU Radio components look like black boxes to a Ptolemy simulation. Then it shows the GNU Radio flowgraph that is inisde. And finally, it shows an example of configuring a block parameter, such as the modulator sensitivity. Information on Ptolemy can be found here: http://ptolemy.eecs.berkeley.edu/ptolemyII/index.htm Questions or comments are always welcome.
