Locked Re: SCRIPTING - Can a script obtain the names of classes that are already running #scripting

 

Hi Bob,

Thanks again for your help.

I've achieved what I wanted to using your code samples, although I did have to change them slightly.? I was receiving errors that suggested the code was expecting 1 more value passed to it than what was being done.? So instead of using:

? ??jmri.jmrit.automat.AutomatSummary.get(i).getName()

I had to use:

jmri.jmrit.automat.AutomatSummary.instance().get(i).getName()

and the same with the code to step through the classes:

range(jmri.jmrit.automat.AutomatSummary.instance().length())

I found this from one of your previous posts on this forum.

Thanks again!

Locked Re: JMRI and DCC++: Exception with Simple Programmer in Ops Accessory Byte/Extended Byte mode #dccpp #4-18

 

Dave,

Thank you for pointing this out. I too suspect the issue is with DCC++ not being updated for a good few years now.

I wouldn't mind fixing the DCC++ code, especially if it boils down to just increasing the maximum DCC packet length.
(Pushing the changes to DCC++ 'official' repository would be another story).

Regards

Tim

I print my manifests to pdf and examine them there.? They show up in color.? Then if satisfied I print to paper from the pdf.? My main reason for going this route is to save toner and paper.

I looked at this at one stage, studied the DCC++ code and found that there's a maximum DCC packet length defined in the DCC++ code and that its one (or possibly two) bytes too short for NMRA S9.2.1 Ops Accessory Byte or Ops Accessory Extended Byte commands.

I came to the conclusion that, in order to solve the problem, the DCC++ code would have to be recompiled with this defined value changed.

But since I don't have the required Arduino hardware, nor the familiarity with recompiling the DCC++ code, plus the fact that there's nothing we can do in the JMRI code to work around it, I put the problem aside.

Locked Re: Canusb ports

 

If Zorin is derived from Ubuntu or Debian, you probably need to have the "dialout" group assigned to the user running JMRI.

In a terminal window, run the id command and see if your user has the "dialout" group.

If not:

sudo adduser ${USER} dialout

I hate computers.
Definitely something haywire with my Windows 10.
I hardwired my laptop to the printer and everything worked as it should.
For some reason, only in that particular screen, it doesn't want to print in WiFi mode.?? Go figure.

Will just live with it I guess.

Locked Re: New JMRI Version breaks my panels #4-18

 

Bob,

I have fixed all of the block warnings.

Block problems are generally caused by inconsistent block assignments. ?There are a couple of basic rules.
  • A block MUST be contiguous. ?For example, a-a-a-b-b-a-a-a is not valid. ?A track component with no block assignment will also break the contiguous rule.
  • Gaps between blocks break block continuity. ?Most of your turnouts do not have block assignments.
  • A good block design facilitates signaling.

Some Layout Editor comments.
  • A valid panel has no red, magenta, or yellow connection points. ?There should only be green connections, along with blue for the A connection for cross-overs and slips.
  • Use the Tools >> Check menu items to look for block issues. ?The should be no "Un-Connected Tracks" or "Non-Contiguous Blocks". ?"Un-Blocked Tracks" entries generally occur for secondary areas such as yards or branch lines.
  • Sometimes Non-Contiguous will occur for separate unblocked areas.

Changes.
  • Missing track segments were added to a couple of sub-panels to fix red/yellow connection points.
  • The anchor points at the end of lines on the sub-panels were changed to end bumpers. ?The was done using the "Change To" entry in the right click context menu ?for the anchor point.
  • The track segment block assignments where extended to include connected turnouts. ?Whether I used he left or right side was arbitrary. ?
  • CP Leech 330 cross-over was added to the main panel. ?Since that cross-over connects Block 915 and Block 916, it has to be on both the main and the CP Apollo sub-panel.

The updated panel has been uploaded to your folder.

Yes, that is correct.? The 23_2 version is the one where I needed to edit the XML file to change LS0 to LS930 because the new version of JMRI did not like the LS0 designation.? That is the latest version of my panel file.

Hi folks, I¡¯m new to DCC world and just got my share on two out of two non-working decoders. One being BLI P3, and while researching P3 issues I came across this thread on CV217.

?

Apparently, CV217 is not supposed to be documented, because it¡¯s a service CV. The below clarification came directly from BLI tech support, when they were troubleshooting my issue. I¡¯m just sharing and hope it can be of use for those working on BLI decoders.

?

BLI tech:

========

After setting CV217=196, it should either work or not work on the program track - but you could set it to lower or higher values to experiment (range of 0-255).

?

When we designed our latest decoder, we wanted to have a lot of capacitance to prevent pickup issues over frogs and such.

However, that design posed a problem with reading CV's sometimes and in some programming modes because when the energy was used to A) Charge the capacitors, and B) "chirp the motor" - the packet of data could not make it round trip back to the throttle.

Our engineer created CV217 to lessen the amount of power that was given to "chirp the motor" to overcome that obstacle. That's why it's not an NMRA standard - it's a BLI thing.

The higher you set CV217, the less power is given to the motor while programming.

Locked JMRI and DCC++: Exception with Simple Programmer in Ops Accessory Byte/Extended Byte mode #dccpp #4-18

 

I am running JMRI 4.18+R37ad3d0 with Java 11.0.6 in Ubuntu, and DCC++ Basestation. When using Simple Programmer in Ops Accessory Byte or Ops Accessory Extended Byte, I get the following error:

2020-02-09 22:56:29,637 ptionhandler.UncaughtExceptionHandler ERROR - Uncaught Exception caught by jmri.util.exceptionhandler.UncaughtExceptionHandler [AWT-EventQueue-0]

The DCC++ Traffic Monitor shows nothing. Alas I am not familiar with Java to identify what and where exactly communication between JMRI and DCC++ breaks.

Can it be the problem with DCC++ Basestation? As far as I understand, JMRI uses DCC++ command 'M' for Extended Accessory packets.
Locked Re: Operations manifest printing #operationspro

 

Phil,
I usually use the "preview before printing" to ensure that what I want to print looks correct.?? Sometimes I also find that what I thought might be one page is two.?? If so I can make changes to print what I want.

I have tried the "Print" without going through "properties", however the result is the same.?? Things just sit there and do nothing.
I even tried changing some colours in the Manifest.?? The colour changes showed in the preview with the same result.?? I did notice that the colours do not show the "preview" to print.? I guess it is using a different path.

I just don't know enough about computers to track this one.??? I have been able to print anything else in the program, except for the Manifest.

Maybe I'll just download the newer version and try it.
I assure the procedure would be to back up my "Operation" files then uninstall the old version before installing the new.

Locked Re: pickup and setout of locos in route #operationspro

 

Gordon,

That's exactly how OperationsPro works, there's only a comment made for the operators, the helpers never move with the train, they only have to exist at the start of the helper location.? No need to build a route for your helpers to return, they never move in the database.

Locked Re: pickup and setout of locos in route #operationspro

 

Matt,
You could operate your helpers as a turn with their own route from where they pickup the train and drop it off. Your route would be from A with no SO's or PU's to B and B with no SO's or PU's to A.
I operate helper service off the grid...JMRI doesn't know they are there. I keep it simple.

Sorry to have to ask another newbie question, but you stated in your reply:

You can also iterate through the list of running automats, etc.
I can't see any method to achieve this on the page you referenced, nor can I find an example anywhere. Would you be so kind as to provide an example of how to iterate through the list of threads displayed in the thread monitor?

One other thought as I try to re-create the error: why do you click on the "preview before printing" in the Canon print window???

Does it print if you do not have that Canon option clicked??

I just checked with my Canon printer and it worked both ways, but I have had problems with my Canon apps in the past so that may be the flaw in the path.

Locked Re: Operations manifest printing #operationspro

 

Irvin,

When you print your manifest from the preview text editor, you are using the editor to print your manifest and not the program.? Your issue is related to JMRI trying to print your manifest.? I need you to check the system console for messages when printing from JMRI.? It may reveal why you can't print.? Also, if you deselect the option to use the text editor for previewing a manifest, does the preview provided by JMRI look ok?
