Usrp_siggen.py exits on Mac OS X


#1

Eric,

Whe I try to run a recent version of usrp_siggen.py from CVS on Mac OS
X,
it produces the requested output signal for just a second or so, then
exits.

I see in the source code, at the end of main:

  try:
     fg.start()
 except KeyboardInterrupt:
     pass
 fg.stop()

As I understand it, this code executes fg.start(), which returns
almost immediately, and then executes fg.stop(), and then exits from
main.

On my system, the code does not wait in fg.start() for a keyboard
interrupt.

For now, in my working version I’ve changed the end of main back to:

 fg.start ()
 raw_input ('Press Enter to quit: ')
 fg.stop()

That works as it should - usrp_siggen keeps running until I type ^C.

Thanks for pointing out the problem.

I’ll revisit and fix.
