Done, I hope changing the field width from 4 to 3 did not break something

Thanks. I'll run that through the tests for this weekend's update.

c) A new "Speedometer" tool, available under the Development menu in
the JmriDemo program. It times the interval between two input
sensors going inactive or active and converts that to scale MPH.
Still rudimentary, but I wanted to see how well it would actually
work. Note that senors only work with LocoNet now; NCE/Lenz feedback
is polled, and I don't have any code to do that.

Is this the begginings of what I was talking about a while ago about
automatically being able to calibrate your loco speed table so the the
throttle indicates scale MPH?

It is, but really only the beginning.

I don't yet understand how people will actually use something like this while programming. Any kind of iterative procedure to find the value for all 28 speed steps would take a _long_ time, and I'm not sure it's worthwhile. For a single value it could work, though I'm not sure how linear the typical locomotive is.

Mostly I'd like to play with it when I get some time on the layout, and encourage other people to do that too.

They work well

Hi Bob,

I just did a CVS update and run to have a look at the value boxes on top of
the sliders and yes the font is pretty small. Even when you set the value to
255 the text only fills about 2/3 of the box width.

I had a play around with the box and font size by tweaking the following
lines:

a) In the DecVariableValue constructor I changed:
_value = new JTextField("0",4);
to
_value = new JTextField("0",3);

b) In SpeedTableVarValue.getRep I changed:

float newSize = (v.getFont().getSize()+0.5f)/2.f;
to
float newSize = v.getFont().getSize() * 0.8f;

This gives me a font size of about 10 and it makes a space between the
sliders of about 1 mm so the page does not change much and makes the text
quite readable.

Looking at the code I'm not really sure what actually determines the width
of the text box and what I tweaked may not have made a difference as with
the above settings there is almost room for another character.

That sounds like a big improvement over the way I left it. Could you commit those changes?

Sorry, I was behind on checking in the source. I just committed a couple of things:

a) The buttons on the speed table

b) Convenience fixes to the roster menu filehandling so that it goes to a reasonable place when it opens the first time, and it remembers where you were later.

How about this Bob,

How About a magnifying feature to work with the small point size.

When one clicks on a slider adjustment or places the pointer on the small
numerical box above it, the numerical box grows larger (even overlapping
other adjacent boxes somewhat if necessary) such that the number become
very visible and easy to change. When one clicks on another slider,
numerical box, anywhere in a neutral window pane area or finishes typing
in the number and hit return, the box that has grown will now shrink back
to normal size showing the old or new value as required.

Another Idea is to have a dedicated numerical box that has a very
readable font size on the window pane some place above the speed table.
When one clicks on any slider, the box is updated to reflect the value
that correlates with that slider. When no slider is selected, the box
goes blank. Data entry is also done with this box. As before when a
slider is selected, the value in the box can be changed by clicking on
the box, making you entry and hitting return. After hitting return, the
box goes back to being just a display box. Of course sliding the slider
will dynamically update both the small font box and the big box. The
purpose of clicking on the box to perform data entry is to prevent
accidental data changes. The changes must be deliberate. Of course your
table graphical editing automation tools will work without clicking the
box.

Sorry to be so long getting back to this topic.

I've made a couple of attempts at getting the digits to line up
vertically, and there doesn't seem to be a clear-cut way to do it.
Perhaps somebody else knows how and is willing to contribute that
code.

Instead, I've added boxes above the sliders and adjusted the font in
them so that they fit. On some platforms, this results in quite
small type (e.g. on Linux, you get 5 point characters); still
readable, but small. You can type the numbers in there directly and
the slider will adjust, or you can move the slider until the number
is right.

I'll put out a test version over the weekend.

Based on predefined first and last speed steps, which are picked

curve that, when set-up in the speed table, result in a gradual
increase in speed from low to high end.

I've added a couple of buttons to:

*) Set the curve back to the default 0 -> 255 straight line

*) Set it to a straight line between existing endpoints

*) Set it to a log curve between existing endpoints.

Now that I've got the mechanism set up, adding additional adjustments is pretty easy.

I don't understand the Lenz product line. What should we put in

the

web pages, etc, so that other people don't hit the same problem?
E.g. is it just the Set 02 that won't work with the LI100?

It is specifically the LH200 handheld which doubles as a command
station. Although it can program decoders on the main and on a
programming track, it cannot communicate with decoders over express
net and therefore cannot be used through the LI100F with software
like DecoderPro to program decoders.

Perhaps you could just mention the fact only the LZ100 command
station can be used with the LI1200F interface and your software,
but Lenz should make this much clearer in there documentation.

to program decoders is my prime interest.

The programs are written to take control of the serial port, so only one can run at a time.

For those using a Digitrax system, Alex Shepherd has built a "client-server" capability. You can run one "server" program that uses the command port, and then multiple "client" apps can talk to the layout through that server. The clients can be on the same machine or on different machines. It really works nicely, but we don't yet have a set of simple instructions on how to use it.

This could be extended to the other DCC systems if anybody were interested in doing it.

The "JmriDemo" program (sometimes written as JMRIdemo and JMRIDemo;

we're not too consistent on that) contains all of the code that
exists. It's got a complicated menu bar with lots of things to try,
and it's missing even the most basic of instructions, so it's not
really a good demo or tutorial.<

If I understand your question properly, there are two parts to the answer.

Right now, "running trains" has only rudimentary support in the code. People seem to have been more interested in aspects of decoder programming, so that's were the work seems to be happening. You can flip turnouts, etc, but there's nothing as handy as the nice screens you see in programs like RR&Co and WinLock. And there's almost no documentation.

Still, progress is being made, with more stuff each couple of weeks.

The "JmriDemo" program (sometimes written as JMRIdemo and JMRIDemo; we're not too consistent on that) contains all of the code that exists. It's got a complicated menu bar with lots of things to try, and it's missing even the most basic of instructions, so it's not really a good demo or tutorial.

Perhaps I can interest somebody in putting something together? That would be a real contribution.

As to downloading these: In the most recent files, they come with DecoderPro as part of the package. On windows, look in the JMRI group in the Start menu and you should see them. On other systems, there should be runnable icons in the "JMRI" directory or folder. E.g. on MacOS X, look for the "JmriDemo" icon and double-click, etc.

If those don't run, please let me know.

Yes, it's pretty clear that everything is communicating.

Can Windigital 8.5 program decoders? If so, that means that the command station will accept programing commands, and there's something wrong with what DecoderPro is sending.

Also, could you try several of the programming modes to see if you're encountering a limitation there? Perhaps the Set 02 can only do "direct mode", for example. To check this, there is a set of radio buttons at the bottom of the screen on which you select the decoder type. They say things like "Paged", "Register", etc. Pick each one in turn and hit the decoder "ident" button to see if it works.

That's interesting.

Those are messages from the LI100, so the program is successfully
exchanging messages with the LI100 over the serial link.

1 4 5 is from the LI100 itself, and means that "instruction was
successfully sent to command or normal operations have resumed

after

a timeout"

But "61 82 e3" is a bad sign. It is from the command station, and
means "Instruction not supported by command station".

It looks like everything is communicating OK, but the Set O2 is
refusing to do a programming operation from the XPressNet. I'm

not

familiar with the Set 02. Is there some option you have to set to
make it accept this? Is it a full XPressNet command station?

appears 1 4 5
1 4 5
61 1 60

with the Set 02 command station. I have also changed the LH200 but
no difference is made.

Alex

Is there a difference between the LI100 and LI100F?

A systematic approach to diagnosis will probably help here.

First, get a consistent set of settings. The best starting place

for

settings is 9600 baud (which should be the LI100's default) and no
flow control.

Make sure the LI100 and command station are talking to each other.
If they are, the LI100's LED will be on solid; if not, it will be
blinking.

Next, start a trace of the serial port by selecting

the "Lenz/Atlas

Command Monitor" item from the "Debug" menu. As you try to

program,

you'll (hopefully) see some traffic in that display. The command

to

start a programming operation is:

22 14 8 3e

And the LI100 will then reply with a burst of stuff. Do you see
either half of that? After a while, you'll see

21 81 a0

which is the program giving up and sending a reset command. Do

you

see this? After how long?
