Re: How can you force the Scheduler to deliver appropriate vector size input

2022-10-25 Thread Ivan Iudice
Hello George, the input vector size is determined (more or less) by the forecast method. If the size is greater than you need, this is not a problem, you need to consume only the number of items you need. You will find the unconsumed items in the next buffer. The problem arises if you need a mini

How can you force the Scheduler to deliver appropriate vector size input

2022-10-25 Thread George Edwards
Hello GNURadio Community, I designed an OOT block to accept vectors of size 448 samples. In the flowgraph, my block is preceded a Stream-to-Vector block with the vector size set to 448 samples. My OOT block expects vector data that are of length 448 or multiple of 448 samples for signal processing

Thanks Marcus. I want to build a marine VHF scanner with an RTL-SDR. So I start at the base marine frequency, evaluate the channel power, and if less than a threshold, go to the next channel, until I see a power > threshold which indicates activity and I stop scanning and switch to demodulati

Hi Jeremy, that sounds very much like your use case calls for a stream of samples rather than a variable being updated. Would that be possible? It's a bit hard to help you without any context, so if you could describe what you're doing, or share a flow graph, or anything, that might help! B

Hi Jorge, hope you don't mind me replying on the list itself - as this is really just the same email as before :) So, yes, you'll need one of gmp or mpir. But these should be there, since you already seem to have built GNU Radio for the ARM target, right? That's what's confusing me. Best r

Hi Jorge, I sadly can't read your screenshot. Would you mind Copy and Pasting the text? GMP and MPIR are the same thing. You only need one of them, not both! Best regards, Marcus On 25.10.22 18:57, Marcus D. Leech wrote: On 2022-10-25 12:17, JORGE GONZALEZ ORELLANA via GNU Radio, the Free & Op
