Re: [Discuss-gnuradio] How to feed the "file source" block?

2013-03-10 Thread Nemanja Savic
You should provide file with sample values inside, and it depends on what kind of signal have you recorded, complex, real, etc.. Since you are collecting some signals, i suppose you are using file sink block in order to store data to file, so all you have to do is to provide that file to file sourc

I am using gnuradio on a 1.6 GHz C2D with 8GB of RAM and 32bit Linux, and most time the CPIU is bored, only compiling takes very long. Of course it depends on what you are doing, but basic stuff is almost unnoticed by the CPU :) Ralph. > -Original Message- > From: discuss-gnuradio-bounc

[Discuss-gnuradio] Configuration Management

2013-03-10 Thread Dan CaJacob
I have a lot of gnuradio and uhd configured nodes around the world. Up until now, we have managed them with a mix of simple configuration management and individual maintenance. However, I'd like to move on to using something more robust, like SaltStack, Fabric, etc. I am aware of Puppet and Chef
