If you use my next branch you can write blocks in python. All facilities of tags and message passing are available in python: http://gnuradio.org/redmine/projects/gnuradio/wiki/WriteBlocksInPython Also, look at gr-uhd/examples/tags_demo.cc for an example of how to intercept and use the tags. -josh _______________________________________________ Discuss-gnuradio mailing list [email protected] https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
