Hi everyone, I want to see a simple cosine signal on oscope by writing a pyhton code. I am using scopesink2.scope_sink_c tool. The code is below:
and I got this error message: [r...@mehmet Desktop]# python mehmet_rx.py Traceback (most recent call last): File "mehmet_rx.py", line 99, in <module> my_top_block().run() File "mehmet_rx.py", line 87, in __init__ num_inputs=0, File "/usr/lib/python2.6/site-packages/gnuradio/wxgui/scopesink_gl.py", line 144, in __init__ msg_key=MSG_KEY, File "/usr/lib/python2.6/site-packages/gnuradio/wxgui/scope_window.py", line 430, in __init__ wx.Panel.__init__(self, parent, style=wx.SIMPLE_BORDER) File "/usr/lib/python2.6/site-packages/wx-2.8-gtk2-unicode/wx/_windows.py", line 68, in __init__ _windows_.Panel_swiginit(self,_windows_.new_Panel(*args, **kwargs)) TypeError: in method 'new_Panel', expected argument 1 of type 'wxWindow *' The python code: from gnuradio import gr, usrp from gnuradio.wxgui import stdgui2, scopesink2, fftsink2, form import wx class my_top_block(gr.top_block): def __init__(self): gr.top_block.__init__(self) sample_rate = 320000 ampl = 1000 decimation = 200 frequency = 1700000000 gain = 1000 #create the usrp source #0 represents the USRP number (in case you have multiple USRPs) u = usrp.source_c(0) #Set the decimation u.set_decim_rate(decimation) #Automatically choose the sub device #(this can be done manually, see below) subdev_spec = usrp.pick_rx_subdevice(u) #Set the mux u.set_mux(usrp.determine_rx_mux_value(u, subdev_spec)) #get the sub-device subdev = usrp.selected_subdev(u, subdev_spec) #Select receive antenna ('TX/RX' or 'RX2'): flex boards only! subdev.select_rx_antenna('TX/RX') #Set the gain subdev.set_gain(gain) #Tune the center frequency u.tune(0, subdev, frequency) self.wxgui_scopesink2_0 = scopesink2.scope_sink_c( self, title="Scope Plot", sample_rate=320000, v_scale=0, t_scale=0, ac_couple=False, xy_mode=False, num_inputs=1, ) self.connect((u, 0), (self.wxgui_scopesink2_0, 0)) if __name__ == '__main__': try: my_top_block().run() except KeyboardInterrupt: pass _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
