Hello
I am executing a flowgraph where I pass different parameters to the work()
function of my block in every iteration.
1. I would like my flowgraph to execute once with a certain set of
parameters and on satisfying a certain condition, it should stop execution
(even if the queue/buffer of the block is not empty).
2. The control should come back to the main() function and the next
iteration should start with a new set of parameters and again upon
satisfying a certain condition the flowgraph should exit.
*The work() function is of the block "test_demo":*
*############new_test_tx.py#################*
class test_demo(gras.Block):
def__init__(self,parameters):
gras.Block.__init__(self,name="test",
in_sig = [numpy.uint8,numpy.uint8,numpy.uint8],
out_sig = [numpy.uint8,numpy.uint8])
def work(self, ins, outs):
--some process here
*The top_block is as following and has code for all the connections(not
shown here):*
class top_block(grc_wxgui.top_block_gui):
def __init__(self,options,llr):
grc_wxgui.top_block_gui.__init__(self, title="Top Block")
_icon_path = "/usr/share/icons/hicolor/32x32/apps/gnuradio-grc.png"
self.SetIcon(wx.Icon(_icon_path, wx.BITMAP_TYPE_ANY))
self.=new_test_tx.test_demo(options.parameters)
def main():
parser = OptionParser(option_class=eng_option, conflict_handler="resolve")
parser.add_option("", "--args",default="",
help="set the address of usrp_device [default='']")
(options, args) = parser.parse_args ()
# build the graph
tb=top_block(options,param)
tb.Run(True)
if __name__=="__main__":
main()
I am able to execute the flowgraph once and then the main() function exits.
I would like to perform this action for some 1000 iterations. It is a kind
of for loop that I use during C/Python programming. How can I use it with
GNURadio and Python.
Thanks and Regards,
Sumedha
