Hello, I'm trying to implement a custom out of tree source block that when triggered with a callback will emit a burst of samples. In my work function I have a check to see if a private variable do_emit is true, and if so it will populate the output items array. If it is false, I do nothing and return noutput_items = 0.
I added a callback function in the grc xml file to enable me to set the do_emit in the generated python script that runs the flowgraph. Is this the proper way to have burst outputs? I'm using the hackrf as my radio. Thanks
