Re: [Discuss-gnuradio] Off-line signal processing (GR in slow motion)

Off-line example (3 separate flowgraphs, run one at a time): 1. USRP -- File 2. File -- AM Radio Demodulation, produces audio data -- File 3. File -- Throttle @ audio rate -- Audio Sink As Tim O pointed out, #3 would just be File -- Audio Sink, since the Audio Sink consumes at a fixed rate

Re: [Discuss-gnuradio] Volk: Am I getting all that's available for ARM?

Just for the record. If the selected floating-point hardware includes the NEON extension (e.g. -mfpu='neon'), note that floating-point operations are not generated by GCC's auto-vectorization pass unless -funsafe-math-optimizations is also specified. This is because NEON hardware does not

Yeah, I think your right, mcpp isn't needed in the gnuradio pybombs recipe. Tim On Thu, Aug 8, 2013 at 9:05 AM, Alexandru Csete oz9...@gmail.com wrote: On Thu, Aug 8, 2013 at 2:16 PM, Tom Rondeau t...@trondeau.com wrote: On Thu, Aug 8, 2013 at 7:37 AM, Alexandru Csete oz9...@gmail.com

rant I would vote for making copious use of the doc section in every block's XML file. For example, as a beginner, I spent a lot of time fiddling with Stream to Vector to figure out the parameters were opposite from what I thought they were. It is frustrating to open up a block's sheet and

Re: [Discuss-gnuradio] Help Pybombs

-DCMAKE_INSTALL_PREFIX for cmake based projects, and the projects install into that prefix. Pybombs is simply running the configure/make/make install for the project you want to install and all it's dependencies. There's no magic about where it installs things.

Re: [Discuss-gnuradio] pybombs building 3.6.5.1 - swapping and out of virtual memory

by adding: make { make } This basically overwrites the template pybombs uses for the make stage, which uses the -j4 by default. It will result in a longer compile time, and again I wouldnt expect a machine with 4GB of RAM to have any problems, even with that option, but its something to try. Tim

I've stepped up to GR 3.7.0, re-used gr_modtool to freshly re-create my OOT module, everything builds, tests, installs OK. GRC has my OOT blocks listed and I can put them on my flowgraph. One of my OOT blocks is a function that takes in shorts and outputs shorts (a 1-to-2 interpolator).
