Re: [Discuss-gnuradio] Synchronizing 3 USRP-N200
Dear Ian and All, Although I tried what you have said, the phase is random and different every time I run the flow graph. I deeply suspect that synchronization is actually done on the boards. I use a GPS receiver for synchronization and yesterday I noticed that the shape of the PPS signal is as the one in the attached image. I am afraid that the ripple and the overshoot can imitate the behavior of the PPS in much smaller period than one sec. Do you believe so? Can I use a usual function generator for the PPS instead of the GPS receiver? In other words, should the ref/pps signal be sync?

First you need to ensure that the measurement of your pps signal shows the reality, and is not some measuring error.

There will be RRC waveform corresponding to every bit out of the source. The RRC waveform corresponding to a bit in source2 should fall between RRC waveform corresponding to 2 bits of source1 ( preferably at the midpoint ). I guess I can not do a streams to stream converter, before RRC, because what that would give me a channel with twice the bandwidth of a single channel.

[Discuss-gnuradio] GNU Radio, ControlPort, and ICE and GCC versions
Just a quick note about some software version info. GCC 4.7 and ICE 3.4.2 don't play well together. If using GNU Radio on a machine with GCC 4.7 and you want to use ControlPort, you have two options: - Downgrade to GCC 4.6 (this is by far the easiest), or - Upgrade to ICE 3.5.0. I have verified that ICE 3.50 and GCC 4.7 build GNU Radio and ContolPort fine. But I had to do a bit of work to get GNU Radio to handle 3.5 properly because we are expressly looking for 3.4. Also, when I built 3.5.0 from scratch, there was no PC file. I was able to copy the PC file from 3.4.2 and just update it accordingly and everything worked fine from there.

[Discuss-gnuradio] Updated GRC categories - prep for v3.7
The next stage of preparing for GR v3.7 is work to make the GRC
component structure more sane. By duplicating blocks, we also made it
more difficult to use the GRC category tree because of duplication
there, too.
But now that we're satisfied that the blocks are working and that we
have transitioned most of the GRC components out of gnuradio-core,
we've restructure the components.
* We removed all of the old blocks from the GRC component tree.
* This does _not_ remove the blocks from GRC, so this does not affect
GRC apps already created.
* The change affects how we find blocks, and the blocks in the
category tree are now (almost) all from 3.7.
* We have changed the category names and reorged all of the blocks, so
it might take a little bit of getting used to. But we feel the new
categorization is more intuitive.
** The next section shows the new category names used.
* When using the component tree, almost all the blocks listed there
are the new blocks for 3.7.
* When opening your GRC files now, if you are using a block that is
from 3.6, the name will be: "Block name (old)".
** This is to make it clear that you are using a pre-3.7 block.
* The (old) name is to help identify where you can update to a new 3.7
block in your flowgraph.
** This will help prepare you for the conversion to v3.7
* The search box will return all blocks found, including the (old)
blocks, so you can still get access to these, if you really want.
Note. Not all GRC blocks were converted this way on master. A lot of
the hierarchical blocks that had a GRC component were not necessarily
moved over to the new components on the master branch. So you might
still find a few problems when opening up old GRC files in 3.7.
To see the list of blocks that are still being pulled in the old way,
you can look at grc/blocks/block_tree.xml in the source code, or it is
installed into ${prefix}/share/gnuradio/blocks/block_tree.xml.
This should really help with transitioning your work to 3.7 when you
need to and in the meantime will not affect your current, running
systems in anyway but looks.

I realized that adding -fpermissive to gcc will make it compile and run as expected. I guess I can now look forward to being publicly crucified at the next C++ convention... On the other hand the Python does the same thing behind the scenes so I will not loose any sleep over this.

I was waiting until I had more time to help you out with this, but no need. It'll be good to have some C++ apps using ControlPort out there for us to look at :) Tom ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
