Yep, I concur. It is blazingly fast at rendering with the HackRF :)Can we control any options on the sink? For example frequency scale, waterfall rate, etc. A callback would be nice too. I'd like to use the fosphor sink in my gr-kx3 script that I use to control my HF transceiver.
This is very cool. Thanks. Darren On 27/10/13 17:12, Sylvain Munaut wrote:
Hi,However, it seems to be quite laggy, with 'chunks' of 'water' 'falling' at about 1 second intervals and not flowing smoothly.Yes, the FCD will not quite provide enough data for it ... It's more aimed at very wideband SDR :p It currently processes data in chunks of 128 * 1024 which for the FCD is pretty big. In lib/base_sink_c_impl.cc , look for "128*1024", there should be 4 matches, and replace them all by 16*1024 (you can't process less than that). It should improve the frame rate for very low sample rate. Cheers, Sylvain
