LabVIEW Version: 7.1

License Type: BSD (Most common)

This is a toolkit to convert a state diagram designed with the editor dia into a LabVIEW state machine.

Warning: This uses Scripting: So be aware of dragons, black holes, rusty nails and other monsters. I've only tested it in LV 7.1., got a crash every 2 hours... Bugs and workarounds in newer LV versions welcomed.

Crashes in 8.5. Found the CAR (# 4CJFKTCS)). Edit: Fixed in V 1.0.1

Basic Operation

***************

Create an uml Chart in Dia (it is OpenSource too).

Compile it into a LabVIEW state machine (this will generate an enum based state machine with .vi and States.ctl for the TypeDefed Enum).

Code the States.

Getting started

***************

* You will need to have several OpenG packages installed. Dependencies: appcontrol, file, variantconfig. In order to install these, you need to get the VI package manager from:

http://jkisoft.com/vipm/download/

* For users of LV 7.x you need to get the TRefTraverse.llb from NI:

http://decibel.ni.co...t/docs/DOC-5091

From 8.0 onward they are located under vi.lib\utility

Propably you need to fix the linking from the main vi

* You will need to download Dia:

http://live.gnome.org/Dia

Customizing

***********

* In the Folder LV Scripting you will find the template 'State Machine Prototype Template.vit'. You can modify this within limits to change the state machine that will be generated.

* There is a lot of Documentation with the Code: Check out the documentation folder with the 'Tree VIs' and the uml diagrams (they are surprisingly also made with dia)

* If you have questions, ideas or found a bug, please do not hesitate to contact me! You can do so via PM on LavaG or via my private email on the BD of the About.vi

V 1.0.1:

* Fixed a bug in error handling (Error Handler Close.vi)

* Workaround for the 8.5 crash

* Support for changed Name of CaseSelect

* Started to add support for StarUML

Happy New Year

Roadmap (unsorted):

* Extending the set of verification plugins

* Loading/Parsing for StarUML/XMI

* Creation of String based State Machines

* Make it available for newer LV versions (see this scripting question)

* Handling of orthogonal states

* Converting Notes to Comments on BD

* Converting Transition Events/Guards to whatever

* Write an easy tutorial

Hi, This looks really neat. How is the progress on the Roadmap?

[SuperS_5]

I looked through this tool. Looks interesting, but very similar to the state-chart module. I tried to use the "Replace - no attributes" method, but, it always failed for me in LV8.6. Replacing to "Replace" and the "Params" disappeared, but everything worked after that. Learning how it parses Dia took some experimented, but, worked great when I got used to it. It is definitely pretty quick, and that is one point against the state-chart module.

Thanks, I'll play around with Replace (instead of RepNoAttrib) next week.

This is one of the main reasons that I have discontinued to work on this project, as I couldn't make it working in other LV versions.

It would be cool to work on this too. I guess the biggest question for me now is how would I participate?

You are welcome. I'll send you a PM so we can discuss this in private.
