The problem is that Modelica-based state-machines (e.g. the clock-based ones in the new Modelica 3.3. standard) or in older libraries, or the state-charts in ModelicaML usually refer to time is some way.
I assume you only want an FSM driven by some eventgenerator of your own?

Lazarescu Sent: den 25 mars 2013 11:59 To: openmodelicainterest@ida.liu.se Subject: Re: Generate C code for external (real-time) environment Hi Peter, Thanks for the reply. I'm looking for something along the lines of Simulink Coder: http://www.mathworks.it/products/simulink-coder/description5.html The purpose is to use OpenModelica to define some blocks of a system in terms of FSMs: https://en.wikipedia.org/wiki/Finite-state_machine These should be: ** simulatable within OpenModelica the usual way; ** exportable (e.g., as a stand-alone C function) that I can then wrap and include in a completely different (embedded) system (e.g., a wireless sensor node -- WSN). In other words, I try to use OpenModelica as high level functional input environment (e.g., for developers with no programming skills), with: ** testing capabilities (usual OpenModelica simulation); ** export capabilities (standalone C code generation). By these I mean something like: -- FSM conditions be encoded as either plain C 'if' or calls to functions that compute them -- these functions should be generated alongside the FSM C code; -- FSM states are decoded using C 'switch' or equivalent constructs; -- the I/O ports of the OpenModelica block are encoded in C as, e.g., function formal arguments (one of these may be the system time, if needed). We intend to use this flow and models as part of a free software high level synthesis of WSN applications. The developer should be able to input the top-level operation of a WSN node, such as: 'every minute read the temperature from port T and send it to the average block on port Ain. Every 60 minutes read the output of the average block from port Aout and send it to the radio input port TX for transmission'. Is there an OpenModelica export functionality close to this that I can use and, possibly, adapt? The API of the generated code is not critical, but the code should be self-consistent -- it should not make references to simulator or other external libraries. I hope this is more clear. Let me know if you need more info.
