Re: [Discuss-gnuradio] How to update FPGA in E100

Hi, We are using USRP-E100, but that requires us to find a Xilinx ISE first. We will go on that but since we can get a USRP1, we want to know how to update FPGA on USRP1 too. We have already successfully compiled it in Quartus, and we want to have a test first. The file and the only file we have

Re: [Discuss-gnuradio] Extending UHD Device Support

Jeffery, The first thing to keep in mind is that everything is GPL'ed (and specifically, *not* LGPL). This means that if you use any UHD host code, you must obey the GPL for EVERYTHING that links in. This goes all the way up to your customer's application. This restriction already applies for G

Re: [Discuss-gnuradio] What is the default action of USRP during underruns?

Nothing is repeated. Samples dropped during an underrun are lost. --n On Wed, Aug 24, 2011 at 10:00 PM, Marcus M wrote: > Hi, > What does the USRP do during underruns? Does it repeat sending the old > samples or does it wait until the newer samples are produced by the > computer? > > Thanks > >

Yooxi, The USRP1 used an Altera FPGA. The USRP E100 uses a Xilinx Spartan-3A FPGA. The FPGA code you want to be modifying is in the fpga/usrp2/top/E1x0 directory. --n On Wed, Aug 24, 2011 at 9:30 PM, xi yang wrote: > Hi, all, > > We have made a FPGA FFT module. > We downloaded the UHD source c

Hello All, I'm trying to use FFTW in the development of a new signal processing block. The ./boostrap and ./configure commands work fine, but when I type the make command, I get the following error: /usr/src/gnuradio/gr-deteccao/lib/.libs/libgnuradio-deteccao.so: undefined reference to `fftw_exec

[Discuss-gnuradio] Two instances of QT GUI Sink in a single program

Is it possible to put two QT GUI Sinks (FFT displays) in a single application window? I want to use one to show the radio spectrum (to/from UHD) and another to show the audio spectrum, at the same time. When I put two QT GUI Sink blocks in a GRC graph, I see only one of them in the application win

[Discuss-gnuradio] Can't reliably do T/R switching with valves with UHD and RFX400

I am trying to switch a GRC transceiver between transmit and receive using a boolean variable that shows up on the GUI as a pair of QT radio button or as a checkbox. The boolean variable controls two valves, one between the UHD source and the rest of the receiver, and the other between the transmit
