Hi,
I'm assuming you're talking about fl2k here ? Please always be explicit, this mailing list is used by several different SDR projects and not just fl2k.
I was contacting to ask if there is any reason that the examples use standalone binaries to interact with the fresco chip rather than writing a library for gnuradio. Did something about gnuradio make the fresco's integration with it impractical? Would I be better off proceeding by writing a gnuradio block for the Fresco sink or a standalone SSB-tx program?
I think it's the other way around ... the fl2k stuff is mostly a pretty big hack and it eats up huge amount of CPU and that makes it quite impractical.
I think the examples are all very specific cases because that allow to optimize them for _exactly_ that application and use a bunch of tricks to try and reduce the CPU usage to levels that you can actually sustain. Making a generic GR block sure is possible, but it definitely will end up being very CPU intensive and as such require beefy machine to sustain the rate.
Cheers,
Sylvain
