Re: [time-nuts] Lady Heather Server On Raspberry Pi 2 Model B?

[Adrian Godwin]

This turned out to be an easy way to run Lady Heather itself (herself ?) on
Linux - it works well under Wine, but identifying the serial port is a
problem. But run Heather with '/ip=localhost' and ser2net to connect to the
USB serial port and all is smooth.

I used the ser2net config line

45000:raw:0:/dev/serial/by-id/usb-Generic_USB_to_Serial_Converter_OCB6T5Y1-if00-port0:9600
8DATABITS ODD 1STOPBIT LOCAL

to identify a specific ftdi converter connected to a Trimble Resolution T
rather than a thunderbolt (it requires 8 / odd / 1)

Re: [time-nuts] Lady Heather Server On Raspberry Pi 2 Model B?

[Didier Juges]

For those who want to remotely monitor their Thunderbolt, I am getting ready to 
put out a new Thunderbolt kit with WiFi.

With the WiFi option, it is a server compatible with LadyHeather in client mode 
over the net.

The prototype is working, I am ready to buy the production hardware, which 
should be available in a couple of months.

Re: [time-nuts] Lady Heather Server On Raspberry Pi 2 Model B?

[Ralph Smith]

I wrote a program called tboltd that does just that. You have the option
of having it write the time to shared memory and using NTP's SHM driver.
You can get it at http://topoatlas.com/tboltd/tboltd.gz. It compiles on
FreeBSD, not sure about Linux. tboltd allows LH to connect while it does
its thing.

That is the right approach, and someone has already done that.
If I had seen this before I completely forgot, but my old friend N5TNL

Original code written for BSD:
http://ralphsmith.org/~ralph/thunderbolt.tar.gz

The  original announcement for the BSD version was almost 6 years ago by
Ralph Smith:

The follow-up by Leigh was right at 4 years ago:
https://www.febo.com/pipermail/time-nuts/2012-January/062566.html


Summary is the thunderboltd service runs and communicates with the
Thunderbolt, provides a network port for Lady Heather to connect to for
remote display and control of the Thunderbolt, and places the time into a
shared memory region for ntpd to pick up.

It works on x86, so I'm getting ready to install an ARM compiler to see if
it compiles cleanly for ARM.  I don't have the right RS232 level
translator yet to connect my Thunderbolt to my ARM system (BeagleBone
Black in my case, not RPi), so I can't check it out directly yet.

You’re right. I may be wrong, but I would expect that either gapd or ser2net 
would want to open the serial device exclusively, which would spoil things.

You might investigate whether you could make some sort of intermediate service 
that could be a client of gpsd and provide the listening socket for LH. If 
you’re fortunate, LH may be able to just connect up to gpsd directly. gpsd has 
the wherewithal to interleave client access, if I am not mistaken.

Of course. You just have ordinary ntp peers for that.

That’s true. My goal, though, was just to contribute to the ntp pool, so

That’s exactly right - it doesn’t claim stratum 1 until it gets an ntp lock 
over the network (at which point it can claim stratum 2 normally), and then it 
starts to take the pps updates and claims stratum 1.

The issue with the serial data stream in my case is that there’s no 
synchronization in it that’s sub-second accurate. That is, there’s no way to 
know which leading edge of which bit in the NMEA sentence is lined up with the 
start of the GPS second. And even if you get that, the serial driver doesn’t 
have any mechanism to accurately time-stamp the incoming characters - at least 
not nearly as well as the pps device. Now, that may not be the case with the 
tbolt, but with the module that that server’s using, trying to actually sync 
acceptably with gpsd is an exercise in futility. It’s much faster to just 
ignore the serial data and get synced initially over the network.

How does who decide what data goes to ntpd and what goes to LH?

If you have 2 serial ports, it would be easy to wire the pin from the TBolt 
to feed both serial ports.

ntpd knows enough about TBolts to tell it to send the time every second.  It 
would be easy to teach it to ignore stuff it doesn't want and doesn't already 
ignore.  That would let LH drive things and ntpd would just listen in on the 
second port.

It should be possible to duplicate the data stream in software, but I don't 
know how to do that on Linux.

Lady Heather is a pretty simple program,  but it is rather long and divided into 5 files. 
 Just getting set up to compile it in a new environment can be quite a challenge to the 
un-initiated (acouple of toupees worth of hair pulling once you can compile and link a 
simple "hello world" program.
Then you need to figure out how to draw dots and characters,  talk to the

once you are familiar with your operating system/environment,  but not

Hi Mark,

But QT would have also slowed a DOS era processor to a stop, and

run Lady Heather and display the data.

Re: [time-nuts] Lady Heather Server On Raspberry Pi 2 Model B?

[Nick Sayer via time-nuts]

I’m going to guess “no,” because only one thing can connect to the ser2net 
socket at a time.

If I were going to do it, what I might do is connect up the PPS output of the 
tbolt to a GPIO pin of the RPi and configure that pin for the pps device and 
set up ntpd for that. That way, LH can have the serial interface all to itself. 
I’ve done this with a far more ordinary GPS module to make a public stratum 1 
server out of a Pi Zero for the NTP pool (ntp.kfu.com).

No, ntpd would be getting time from the serial port, not from the network
socket.  The idea would be that ntpd was getting the clock time from the
serial port, but the time messages would be interleaved with whatever data
the Thunderbolt was sending back in request to the LH commands.

LH would also be seeing the time messages, but it sees those anyway, so I
think the only concern would be the behavior of ntpd when all the data
from LH commands is going by.  Possibly a second concern of whether ntpd

You still have to get wall clock time from somewhere, PPS just delineates
the seconds, it doesn't name the seconds.
For some cases you could have ntpd get the starting time from another
network source and just use PPS to keep track of the seconds after that,
but then you would still have corner cases of knowing when leap seconds
occurred, maybe others.
And of course if you relied on network access to other time servers you
could not operate on an isolated network.

How did it get the correct time set at startup?  Did it have to query
other network servers to set the time, then the PPS controlled the clock
after that?
Can it be a "stratum 1" server if it has to rely on another server to get
the correct time when it starts up?  I guess it could if it doesn't serve
time until it has checked with other stratum 1 servers to make sure the
time is correct.

Sorry, didn't mean to go off into those weeds, but that isn't the system I
want.
I want a machine which can get the correct current time without reference
to another system, which means that ntpd must get the time information
from somewhere, either by directly reading the serial port, or passed
through from gpsd which is reading the serial port, or some similar setup.
The PPS driver would be connected directly to ntpd.

If you telnet or nc into your rpi on port 3200, you should get a connection and 
you should get a bunch of garbage. If not, ser2net isn’t working. Is it 
running? sudo /etc/init.d/ser2net restart (did you do that after changing the 
config file?)

If ser2net is working then it must be something about the LH params that’s 
incorrect. Do you have the correct IP address and port? Is there anything 
between the two - firewalls or routers or the like?

Can ntpd using a Thunderbolt as a time source run cooperatively with LH
accessing the same Thunderbolt over ser2net?  That seems like the best
case scenario for using a small ARM system with a Thunderbolt as a time
server.

Re: [time-nuts] Lady Heather Server On Raspberry Pi 2 Model B?

[Mike George]

Ed:

A few recommendations for troubleshooting.

In /etc/ser2net.conf comment out the 4 default lines (/dev/ttyS0-3)
so that the line Nick provided is the only config present.

Stop ser2net:
 /etc/init.d/ser2net stop
then restart:
 /etc/init.d/ser2net start

Make sure ser2net is running:
 ps -ef | grep ser2net

If not, tail /var/log/syslog and see if any errors were reported on 
statrtup.

Normally you just see a single line reporting successful startup.

If it is running , make sure it is listening on the socket you specified 
(3200):

   netstat -tln | grep 3200

you should see a line with 0.0.0.0:3200 under local address

There is additional troubleshooting you can do depending on results
of above steps.

Good luck.

Mike

Re: [time-nuts] Lady Heather Server On Raspberry Pi 2 Model B?

[Chuck Harris]

If you stick to something like QT4, which is either python,
or C++, it is rather easy.

QT4 has everything set up for you already, and a compiler for
the graphics screens.  You create the basic screen in the
designer, and tell it what you want it to do when a mouse
hovers, clicks, drags, etc... and it does it.

QT4 also has all of the fancy graphics routines you could
imagine wanting... including routines to plot graphs, polar,
linear, log, bar... whatever.

Tons of tutorials are available on line... as are lots of
complete projects... open source and all that.

QT4 is oriented towards C++, but it has been ported to python.
This opens up a broad world of mathematical and plotting libraries,
as well as USB, IP stacks, printing routines, everything.  The
big problem is the tutorials are for C++, and there are some
pretty significant differences between C++ and python.

Life would have been 1000% easier for Mark and John if they
had used QT4 in the first place Especially Mark, as his
original work was for DOS, which needed extreme hand holding
for every little thing.

The biggest problem I found was not getting totally confused
by the extreme number of #ifdef statements that made it work
on this, or that variation of DOS, 'Doze, debug...

Re: [time-nuts] Lady Heather Server On Raspberry Pi 2 Model B?

[John Miles]

The server is a console app that uses plain Winsock calls derived from the BSD 
sockets API, so it could run on anything down to and including an Arduino 
without too much work.  Porting the GUI client to anything else would be a fair 
bit of work, though.

Not all that much work.  There are only a few routines that would
need to be supplied for screen, mouse, and serial I/O.


Hi Mark and all,

How much *skill* is needed to do a port?  I'd love to have a Nortel 
NTBW50AA / NTGS50AA GPSDO source (while the Z3801 continues to work, it 
does fail self-test), but the thought of having yet another Windows PC 
going in the shack gives me hives.  (okay, maybe not that bad, but...)


A Raspberry Pi on the other hand doesn't take up much space, has the 
ability to be remote controlled easily, and would probably lead to me 
purchasing one of the Nortel units.


So I'd love to see a port, but given that my last programming effort was 
FORTRAN 77 and Windows basic (although I'm learning C for the MSP430 at 
the moment) I wonder if I've got anywhere near the skills to do it...


thanks much and 73,
ben, kd5byb

LH is an excellent program, and it needs to be brought into
polite society, by making it run natively on all platforms.

Changing it to Python, and PyQT4, is easy, but there is a lot
of code base to sift through.

Once on Python, and PyQT4, it will run natively everywhere.
Including smartphones and tablets.

Well, you can run Windows 10 on the Pi...

As the question was running LH Server, perhaps it could be compiled as a
