Heio SDR people, on https://twitch.tv/gnuradio, the GNU Radio dev call is about to start. I'd like to remind everyone that asking questions there, in our #gnuradio:gnuradio.org Matrix room, or on the bridged #gnuradio on the libera IRC network, and also on Discord, is heavily encouraged!

Re: Meaning of value in noutput_items for an OOT with vector input

2022-04-21 Thread Jeff Long
Right. Of course you can just use one loop of noutput_items * vlen iterations. Technically noutput_items says how many items you may write, not how many the scheduler is delivering (implying input). In a sync block, they are the same though, unless you overwritten forecast(). On Thu, Apr 21,

Hi Jeff, Thanks for your reply! So let me make certain that I understand correctly your response where you said there were 16*512 samples (8192 samples). So I take it that noutput_items (which has alternating values of 15 and 16 when printed to the screen) tells me the number of vectors of vlen

Hi Marcus, Thanks for offering to assist me. The OOT signal processing blocks I have designed so far worked with streaming data. For this project, I wish to pass the data in as vectors (which is new to me). I am writing this OOT block to accept a vector of 100 floating point elements on each

You'll have to tell us what you do with that `data` and what the io_signature of your block is. On 20.04.22 17:22, George Edwards wrote: Hello GNURadio Community, In an OOT QA testing of a signal processing block designed to accept an input vector of 4 elements, I am having problems passing
