Hello to everybody. First of all, I am working with Ubuntu 10.10 and GNU Radio 3.4.0. I tried to run the usrp2_wfm_rcv.py graph but I got the following error:
Traceback (most recent call last): File "./usrp2_wfm_rcv.py", line 289, in <module> app = stdgui2.stdapp (wfm_rx_block, "USRP2 WFM RX") File "/usr/local/lib/python2.6/dist-packages/gnuradio/wxgui/stdgui2.py", line 36, in __init__ wx.App.__init__ (self, redirect=False) File "/usr/lib/python2.6/dist-packages/wx-2.8-gtk2-unicode/wx/_core.py", line 7978, in __init__ self._BootstrapApp() File "/usr/lib/python2.6/dist-packages/wx-2.8-gtk2-unicode/wx/_core.py", line 7552, in _BootstrapApp return _core_.PyApp__BootstrapApp(*args, **kwargs) File "/usr/local/lib/python2.6/dist-packages/gnuradio/wxgui/stdgui2.py", line 39, in OnInit frame = stdframe (self.top_block_maker, self.title, self._nstatus) File "/usr/local/lib/python2.6/dist-packages/gnuradio/wxgui/stdgui2.py", line 60, in __init__ self.panel = stdpanel (self, self, top_block_maker) File "/usr/local/lib/python2.6/dist-packages/gnuradio/wxgui/stdgui2.py", line 81, in __init__ self.top_block = top_block_maker (frame, self, vbox, sys.argv) File "./usrp2_wfm_rcv.py", line 118, in __init__ self._build_gui(vbox, usrp_rate, demod_rate, audio_rate) File "./usrp2_wfm_rcv.py", line 201, in _build_gui callback=self.set_gain) File "/usr/local/lib/python2.6/dist-packages/gnuradio/wxgui/form.py", line 225, in __init__ nsteps = int((self.max-self.min)/self.step_size) ZeroDivisionError: float division I read in the mailing list that this problem could be related to the setting up of the gain slider control but I don't know how to fix it. Could anybody help me? A lot of thanks! Regards. Eduardo.
