[Discuss-gnuradio] using daughterboard IO pins

[Chuck Swiger]

Gang - Is there a trick to using the IO pins? I tried this:

sink = usrp.sink_c(0,64)
sink.read_io(0)

 and it hangs up. Trying:

sink.write_io(0,0xffff)

gets a segfault and python bails out. Same thing with

sink._write_oe(0,0xffff,0xffff)

- segfault.

I need someway to read a morse code key 8^)

From what I can tell the basic Rx/Tx d'boards just have pin headers
for IO so playing with sink._write_oe() shouldn't hurt anything.
