I'm trying to modify some code from the multi_fft.py example file and
don't understand what an error message is trying to tell me.
I've searched with little success.
The original works, but anything I've tried to do (e.g. am
demodulation, audio output, resampling) fails with a similar "not
coercible to endpoint" message.
Original code segment:
for i in range(nchan):
scope = fftsink.fft_sink_c(self, panel,
sample_rate=input_rate/sw_decim,
title="Input %d" % (i,),
ref_level=80, y_per_div=20)
vbox.Add(scope.win, 10, wx.EXPAND)
if options.filter:
chan_filt = gr.fir_filter_ccf(sw_decim,
chan_filt_coeffs)
self.connect((di, i), chan_filt, scope)
else:
self.connect((di, i), scope)
Modified segment:
for i in range(nchan):
scope = fftsink.fft_sink_c(self, panel,
sample_rate=input_rate/sw_decim,
title="Input %d" % (i,),
ref_level=80, y_per_div=20)
vbox.Add(scope.win, 10, wx.EXPAND)
rr = blks2.rational_resampler_ccf(3, 2)
if options.filter:
chan_filt = gr.fir_filter_ccf(sw_decim,
chan_filt_coeffs)
self.connect((di, i), chan_filt, rr, scope)
else:
self.connect((di, i), scope)
# raise ValueError, "Not coercible to endpoint: %s" % (x,)
#ValueError: Not coercible to endpoint:
