Re: Optimised and Verified STM32F4 Codec 2 port

Gullik Webjörn — 2013-05-24T09:49:22

This is great news!!

I bought (like many others) the STM32F4 discovery kit for essentially the
postage, in my case with the explicit intention to port Codec2 and the fdm
modem. Now I can have a small "codec2" module.......

I believe it is *very* useful to have a small embedded platform to enable
focus on "system level and integration".

Cheers & 73

Is this for a 40ms audo frame? If so, that would mean 87,5% to 100% usage,
which would mean that it may be possible to operate on a single
microcontroller (including maybe a second one for other tasks, or maybe
even not, if one could operate the other peripherals on DMA). That would be
sweet!

Thanks for your patch!

As David mentioned, I have been working on hamlib integration these
past few weeks. It covers some very similar ground to the work you
have done here.

I was wondering if your HID based rig has support in hamlib? I see the
following[1] rig type, which suggests yes. If that is the case, we can
get support for not just your radio but a large number of them by
using hamlib.

We tested a proof of concept hamlib FreeDV build on an IC-7200 earlier
this week, a serial over USB device. After proving that it worked, I
have gone ahead with integrating it properly. That is a work in
progress, but you can view the code on the 'hamlib' branch at
github[2]. I will finish off the integration and produce a build for
others to test with their rigs this weekend.

Git Mirror

Joel Stanley — 2013-05-24T05:58:12

Hello,

I'm a big fan of the Git version control system. To facilitate my
experiments with hamlib, and to make it easier for others to prototype
and share their own experiments, I have created a mirror of codec2-dev
and freedv (aka the fdmdv2 directory) Subversion and placed it on
github.

 https://github.com/shenki/freedv

 https://github.com/shenki/codec2

I chose to filter out some of the experiments that have been added and
subsequently removed from svn over time, in order to keep the
repository size down. Please keep this in mind when you consider
adding binaries or temporary files to the main repository.

Svn usernames are mapped to Git names and email addresses. David, when
you extend access to svn for others please let me know so I can add
the mapping.

Git syncs on the hour with the official svn repository. Please let me
know if this is insufficient for anyones needs and I can make it more
regular.

Cheers,

Joel

As a rule, use Makefile.linux (and Makefile.win32) as the golden
reference. It's what David develops with, and therefore it's what I
use too.

To avoid future confusion, I volunteer to remove the autotools files
from freedv (but not codec2, as this works well) svn this evening. I
will leave config.h for the time being, but it should go away shortly
too.

Looks like whoever updated src/version.h got it right (0.96.2) but we still
have the redundant version.h...

I tried a new build from the latest svn and everything appears to work
except that I do in fact get a segmentation fault if I try to open the
filters dialog. I'm not sure why. I did notice that I was missing the
dlg_options.{cpp,h} but I can see why. It's missing from Makefile.am which
is what I based my cmake config on, but it is present in Makefile.linux and
Makefile.win32...

Also interesting is fdmdv2_plot_waterfall_linux.{cpp,h} is used in both
linux and win32 Makefiles. Do we need fdmdv2_plot_waterfall.{cpp,h} then?

Oops! I hope I wasn't missunderstood. The 0.96 was fine, it was jumping to
0.961 that was the problem... No need to separate the 9 and 6. I'm not sure
what we'd call the last digit anyway, you already have major:0, minor:96
and presumably patch:1 to be incremented to 2 (if it's considered a patch
revision, or maybe 0.97 if it's "minor".

Hello Maitland,

That all sounds wonderful - especially something that lets us use
wxWidgets 2.8.

I'm not experienced in HID issues.  Joel VK5FJMS is also close to having
working hamlib integration (e.g. we've keyed an IC-7200 over USB) .
Joel - can you pls comment on this patch (when Maitland sends it) and
how we combine yr work?

Richard and list: - I've added a few little FreeDV fixes into SVN:

- made 1600 the default
- re-arranged main window and filter dialog so it fits on 800 x 600
netbooks
- created a Tools-Options dialog for misc. options like "test frames"
check box & "setting callsign" plus we can use this for other config
options as they are created.

and bumped the version to 0.9.6.2 as discussed yesterday.

Cheers,

David

This seems to clean up some inconsistant syntax.

We might still want to do this differently again -

wide strings and Unicode seems like a big win.

ideas for wx-2.8 backport - 0.96.1 version

A. Maitland Bottoms — 2013-05-24T01:49:44

Rats, I see there is a 0.96.2 in the works, so I'm
afraid the patches I have won't apply to head.
Actually, these are based upon SVN r1245 back
gefore Dayton.

Still, I would like to get these out for review.

fixup-string-handling.patch
plot-2.8-variation.patch
GetItemText-2.8-variation.patch
preprocess-wx-2.9-features.patch
HID-PTT

Let me describe these patches in this email, but
I will send them as separate emails later.

Whereas wxWidgets version 2.9 is a development
branch that will stabilize as version 3.0,

and whereas there is a great amount of similarity
between the 2.8 and 2.9 versions of wxWidgets,

I have made a stab at having fdmdv2 code support
both versions 2.8 and 2.9 of wxWidgets.

Step 1: It seems that with 2.9 it is possible to
be a little more sloppy with wxString types. So
the fixup-string-handling.patch adds back the
discipline on using wxT() and explicit string
conversion routines. This is bound to help things
stay more robust and avoid bugs. Also, since it
is possible to have variati

Re: sox files and lib

Tzafrir Cohen — 2013-05-23T06:26:30

That is: if you must bundle a library for platforms that don't have it,
make it possible to built with the system library (even better: make
that the default: the configure script checks for it. Trivial with
pkg-config. Or use a configure-time test) and only resort to using the
bundled copy if the system copy is not there.

Distributions have build dependencies in place to make sure that the
system libraries will be in place.

Re: FreeDV Dependencies

Richard Shaw — 2013-05-23T04:16:44

David,

Don't fret too much :) My intention was just to have a discussion, not
force an issue. If these are truly the best options available, then so be
it.

I'm using the DirectX SDK for Portaudio in my Windows build so it's "as
good as it get's" on the windows front from what I can gather.

The only serious substitution I can think of at this point is if we're
going to stick with sox, then we ought to evaluate soxr to see if it's a
good replacement for libsamplerate, as it's more soxish and of a child
project of sox.

The only other serious problem (at least to me) is that statically linking
with wxWidgets bloats the freedv binary to about 120MB, but I'm not sure we
have any viable alternative... Even if I could get dynamic linking working,
we would still need the runtime DLLs which would take up the same amount of
space...

Re: sox files and lib

Richard Shaw — 2013-05-23T04:08:44


Exactly. If there's a problem with the library then it should be fixed
(ideally). Copying it to work around the issue should be a last resort.


This is going to be a problem if a distribution has an old version of


The biggest issue with wxWidgets is that 2.9 is not a stable release,
it's effectively a 3.0 preview release which is subject to change. The
current Fedora maintainer has been gracious enough to come up with a
parallel installable package for 2.9 for Fedora, but has no interest in
maintaining a development branch, which I can not fault him for.

If it comes down to it I can volunteer to maintain the 2.9 branch until 3.0
is released and file a review request, but until FreeDV reaches some sort
of critical mass, it's just easier to have a separate FreeDV repository on
freedv.org.
