[Discuss-gnuradio] Bug in volk on armv6

2013-07-01 Thread Alexey Bazhin
Hi! I would like to report a bug in volk on armv6. There is infinite "while" cycle in volk/tmpl/volk_cpu.tmpl.c function "has_neon" (line 111). Code "while(!found_neon && auxvec_f) {" will loop infinitely if there is no neon in platform. found_neon will never be true and file descriptor auxvec_f

Hi all guys, i have just wanted to build and install 3.6.5.1 on my system (RHEL6, 64bit). I did cmake, and warnings about missing header files came out, for example: Looking for intrin.h - not found > Performing Test HAVE_WERROR_UNUSED_CMD_LINE_ARG - Failed > Performing Test have_maltivec - Faile

[Discuss-gnuradio] Setting the DSP frequency in the UHD blocks

2013-07-01 Thread Wallace, Frank L CIV NSWCDD, Q41
In gnu radio companion for a UHD block, how do I set the DSP frequency as well as the RF frequency. I have done this in my C code which doesn't use gnuradio using the tune_request_t structure. From the comments in the python code, it appears that there is some way to do it. I understand that

Hi Frank, Use the following line as the frequency variable for the 'UHD Source' & 'UHD Sink' blocks in GRC: uhd.tune_request(center_freq, rf_freq=(center_freq+lo_offset),rf_freq_policy=uhd.tune_request.POLICY_MANUAL) Where 'center_freq' and 'lo_freq' are variables which need to be defined. Usin

If you've been having trouble today getting a successful build out of build-gnuradio, please update your copy of build-gnuradio and try again. The "main" branch was updated to 3.7.0 and I didn't know that, so build-gnuradio was dutifully fetching "main", and then fetching various OOT modules

This is a question primarily for Marcus D. Leech (aka patchvonbraun): In your simple_fm_rcv project, you have a "Multiply Const" block that contains the constant 3.16k whenever stereo is enabled. I presume this is used to amplify the level of the "L - R" signal to reach the ideal level of separati
