Latency due to hardware initialization

2023-04-24 Thread Ahmad Oweis
Hi all, I'm investigating the factors behind the latency in my simple GRC flow graph, I have a theory and I'd be grateful if someone can confirm it or refute it. Say I have a simple flow graph consisting of a file source connected to a hardware sink. My understanding: when I run the flow graph,

Do you have pygccxml and castxml installed on this machine? And if so, are they recent versions (pygccxml >= 2.0) When gr_modtool bind is called, pygccxml compiles the project headers then scrapes the symbol information to generate the python bindings. Not finding memory.h sounds like an outdate

porting OOT to 3.10.5 missing memory.h

2023-04-24 Thread Grace Yeung
Hi, I am trying to port my OOTs from gr 3.8 to 3.10. Following the porting guide and running "gr_modtool bind" work on all our machines running 3.10 except one that is on 3.10.5 where block.h tries to include memory.h which is missing. What's the best way to get around this besides just copying

Logging question

2023-04-24 Thread Volker Schroer
Hi, I'm trying to understand gnuradio's logging. So I setup a simple flowgraph signal_source -> throttle-> add const-> time_sink. To enable debug logging I have to set [log] debug_file = stderr debug_level = debug log_file = stdout log_level = debug in ~/.gnuradio/config.conf or in $CMAKE_INS
