I assume you made that block with gr_modtool. That should have produced a blockname.grc in your grc/ directory, and when you modify that, you'll get your GRC block. Best regards, Marcus On 10/16/2015 07:23 PM, Pedro Gabriel Adami wrote: > Dear all, > > I have a block .py and I'd like to add it

Just throwing this out there, but your low pass filter has a cutoff frequency of 7.5 kHz. It looks like you are trying to use the Slider with the ID "width" to change the cutoff frequency of the low pass filter. It doesn't look like it's actually connected to your low pass filter though because

I have installed ctrlport and playing around with it. What a great piece of work! thanks guys! I am running an application (cdma_txrx from my gr-cdma module) and I notice that with ctrport enabled it crashes, while without it works perfectly. With ctrport I get the following message that hints

[Discuss-gnuradio] Suggestions for C++ Coding of a new PRNG

2015-10-16 Thread Jason Noble
So I'm working on an FHSS implementation. I'm using a XORSHIFT PRNG. I wanted to make a GRC block so I can configure certain parameters for the PRNG (seed numbers, total number of hops to generate, etc.). The only output is an array (or vector output?) storing a hop sequence of, for example,

Re: [Discuss-gnuradio] Saving data

2015-10-16 Thread Marcus Müller
Hi Pedro, that's what the file sink is for -- "sinking" data into files. It's not producing a text file, because text files are pretty much a bad format for floating point values, usually, because you'd either be wasting enormous amounts of storage space to save each number in a textual format

2015-10-16 Thread Marcus Müller
Hi Jason, from a data flow perspective, your block is a /source/, because it doesn't need input, and produces output. In fact, although the sequence is only generated once, it can be iterated through arbitrary many times. So, without much doubt, this is a stream block source (which is a

Hi Achilleas, I can fully relate to the problems you've encountered with thrift; the problem is that their build system is "a little broken" on Fedora; I have saved the options I passed to ./configure to make it build; for example, I couldn't get the tests to build, nor the tutorial: ./configure
