Running Flowgraph some a certain period of time

Hello GR,

  • Is there a way how to run my flowgraph for a given number of
    minutes/seconds then stop it.

  • I’d like to know too how to reconfigure my flowgraph (after I stop it
    from
    runtime) and resume its run after I changed for example the signal
    source at
    the begin of the flowgraph.

I tried:

My_flowgraph Description

def MyRoutine(args):
global tb
.
if (condition):
tb.stop()
myModifiedflowgraph.myModifiedflowgraph(args)
.
.
.####.

if name == ‘main’:
global tb
.
.
threading.Timer(10,myRoutine).start()
tb.Run(True)

My point here is that I need to run myModifiedflowgraph for a certain
period
of time then stop it and resume tb. FYI myModifiedflowgraph is the name
of
the other py script which contain the modifiedflowgraph called also
myModifiedflowgraph.
Any hints or explanations are well appreciated

Regards,
Ruecan

    Of course.
    If what you really want to do is doing a certain number of samples,
    the head block is what you need.

If your end condition really comes from outside, you should use
something like topblock.start(), [wait 5s, e.g. using time.sleep()],
toblock.stop(), topblock.wait()

This is not really reconfiguration, as far as I understand your
architecture. It is stopping and starting two different flowgraphs -
which is ok in theory, but you have to find a way to share the
hardware between the two. Which usually defeats the purpose of having
reconfigurable flowgraphs-adjusting your receiver structure to
changing environment.
In this case, it might be a good choide to disconnect() only the
blocks in tb that need to be replaced and connect() the new ones.

Greetings,
Marcus
