This is the working code but if I comment the last line the scopesink seems
"freezed" and I can' t even close it.
Chiara,
The audio sink effectively throttles your data streams to the
"sampling_freq". When you remove the audio sink, the computer has no
limitation on the rate at which it streams data from block to block...
the CPU usage jumps to 100% and the gui struggles to respond to user
input (hence the freezing).
Place a "gr.throttle(gr.sizeof_gr_complex, sampling_rate)" block right
after the "gr.sig_source_c" to artificially throttle the data stream.
What's wrong with my code?
Can I use scope_sink_c instead of scope_sink_f? How?
Change the scope to:
scope = scopesink2.scope_sink_c(panel,"Input -> USRP", sampling_freq,
num_inputs=1)
self.connect(src0, scope)
-Josh
Thanks in advance
Chiara
