[USRP-users] RFNoC: Radio --> RFNoC:FFT with stream args
Hi, I am creating a grc flowgraph with RFNoC blocks, some of which are custom blocks I created. To start, I am simply trying to connect an RFNoC:Radio block (in RX mode) to an RFNoC:FFT block, where I am setting the spp parameter in the Radio's Stream Args box to the FFT size (spp = 128). I see quite a lot of discussion in the group over the years regarding this issue. Setting the spp parameter doesn't work for me. In fact, it doesn't seem to do anything. I always get the error: Source IO size "8" does not match sink IO size "1024", no matter what I set spp to. Any ideas? thanks, Jim ___ USRP-users mailing list USRP-users@lists.ettus.com http://lists.ettus.com/mailman/listinfo/usrp-users_lists.ettus.com
[USRP-users] problem installing uhd-fpga related to pyqt5
Hi, I am installing gnuradio/rfnoc on a Ubuntu 14.04 machine using Pybombs. Everything goes well until it starts to install uhd-fpga, and the first thing it tries to do here is install pyqt5 (PyQt 5.6). When configuring the pyqt5 package, it says "Configuration failed. Re-trying with higher verbosity." Then I get the failure "Error: Make sure you have a working sip on your PATH or use the --sip argument to explicitly specify a working sip." I don't know what to do here. I've installed gnuradio/rfnoc before but never got this error. I saw something online stating that pyqt5 requires Python 3.5 or later, and I only have Python 2.7.6 and 3.4.3, so maybe that's the problem??? Please help. Thanks. ___ USRP-users mailing list USRP-users@lists.ettus.com http://lists.ettus.com/mailman/listinfo/usrp-users_lists.ettus.com
[USRP-users] RFNoC:Delay block?
Hi, I am wondering if there is some type of variable delay block available in RFNoC. I see that there is a Delay block available in gnu-radio, but I need it to be in the FPGA.
