[Discuss-gnuradio] Why nothing change after I modified some codes in C++ block and successfully compiled it?
Hi guys, Thanks in advance. I have added some codes in c++ block, like *printf(i=%d\n,z);* for output test. However, after I compiled the modified block *(.cc file)*and generated the new object file* (.cc.o file)*, nothing printed out from the terminal, which means nothing changed in the original code. But actually I did. I feel so confused, hope everyone can help me. The example I used is in */home/k/src/gnuradio/gr-digital/examples/ofdm*, and the file I modified is /home/k/src/gnuradio/build/gnuradio-core/src/lib/gengen/* gr_peak_detector_fb.cc*, which is one c++ block connected by ofdm example. Best, Kay. ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio

Best, Kay. You have to run 'make install' after rebuilding or the system will just use the old installed libraries.

[Discuss-gnuradio] Updated UCLA ZigBee / IEEE802.15.4 blocks
Hi everyone, I updated the UCLA ZigBee blocks[1] to GNU Radio v3.6.4 (current master branch) and uploaded them to Github: https://github.com/bastibl/gr-ieee802-15-4 Currently, it just features basic, separated rx/tx chains. There is also a simple firmware for TelosB motes that I used to test interoperability. The firmware is based on the Contiki OS for embedded devices. In the next months we want to extend this with ideas from pre-cog[2] and build a simple transceiver systems to use in our lectures.

Re: [Discuss-gnuradio] uhd transmitter receiver
You can use FFT sink block to see your signal.Just connect after your USRP source block where you can see your received signal. - Manjusha -- View this message in context: http://gnuradio.4.n7.nabble.com/uhd-transmitter-receiver-tp39996p4.html Sent from the GnuRadio mailing list archive at Nabble.com. ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
Re: [Discuss-gnuradio] uhd transmitter receiver
i didn't mention any port numbers in my grc file.U can still set up sink and source blocks on the same grc file.since the usrp knows that sink is to transmit and source block is to receive. all you need to do is connect them and run the grc files. - Manjusha -- View this message in context: http://gnuradio.4.n7.nabble.com/uhd-transmitter-receiver-tp39996p40002.html Sent from the GnuRadio mailing list archive at Nabble.com. ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio

It doesn't look like there is the equivalent of Complex To Real for integers. Is there an alternative to converting to floating point and back? you could vector to streams, and null sink the second stream. * 1 input stream of vec length 2 and item size short * 2 output streams of item size short This works well.
