How to use thread in papyrus-rt application and are there more samples projects? [message #1737922]

I've try the papyrus-rt application in "Combining Papyrus RT with normal Code" topic. But seem the thread configuration in Top.Controller were not used in the output of C++ Code Genearation. (I attached the generated C++ code, seems no threads used in it)

there are 3 threads in Top.Controller,

Top = MainThread
Top.ledInterface = LEDInterfaceThread
Top.switchInterface = SwitchInterfaceThread

1. Could you tell me how to assgin capsule to these thread? and Are there any conceptions of logical thread and physical thread(like in RSARTE)?

2. Where can I get more samples projects and documentations for learning ?

Best Regards
Xiaoyu

I already provided an answer to those question to your previous question. I'm reproducing them here for completeness.

Note that the Top.Controller file is a temporary measure until we implement threading support within the Papyrus-RT. It is provided for experimentation only and it will be replaced once with implement a better thread mapping capability.

The Top.Controller file is used to map a capsule role to an OS thread.
The syntax within that file is "[capsule|capsulePart] = OSThreadName". Each assignment needs to be on its own line.
For example:
Top = TopController => The runtime creates the "TopController" OS thread and assigns the Top capsule it.
Top.pinger = =PingerController => The runtime creates the "PingerController" OS thread and assigns the "pinger" capsule part from the Top capsule to it.

The "LEDEmbedded" model was meant to illustrate a design pattern to interface to hardware and was not meant to be executable.

We have not yet decided how we will approach the concept of "logical threads" and handle its migration to Papyrus-RT. This will be implemented as part of the "thread mapping" capability mentioned above.
