Re: [Discuss-gnuradio] Working with Tags

so much about the tags stopping except that I sometimes have a dropped packet and the timing is off from then on. From: discuss-gnuradio-bounces+mark.w.christiansen=l-3com@gnu.org [mailto:discuss-gnuradio-bounces+mark.w.christiansen=l-3com@gnu.org] On Behalf Of Paul David Sent: Thursday

[Discuss-gnuradio] Working with Tags

I wrote a block that writes the rx_time tag and another block that reads it. After reading them for a 20 to thirty calls to the work function, it stops getting any. The amount it reads varies from run to run. Any ideas? This code snippet is from the work function my block that writes the tag. Th

[Discuss-gnuradio] python keep running

I have a GRC file that brings up a QT spectrum. I run grcc to create top_block.py and then run python on the top_block.py. When I click the close icon in the upper right corner of the spectrum window, the window goes away but the python is still running. Do you know why that might happen? Mark.

The message passing interface works for this. I have a VITA-49 depacketizer I wrote and I used message passing to set the center frequency for QT Frequency Sink because it already has a frequency subscriber. But to use it in general, I have to change every block that needs information from the d

[Discuss-gnuradio] GNU Radio Python execution from C++

I want to start up and control GNU Radio top_block.py from a C++ class I have written. My thought was to execlp() python on the top_block.py file. I run into a problem because I do not have a good way to kill GNU Radio from my class short of sending a SIGINT. How do you recommend I do things?
