Using a Database in RTWS and Simulink with the same code

Hi,

i'm developing a model which will be used to simulate and verify some FSM and write the results into a database.

Currently im using SQLite via extrinsics aka mksqlite, which works perfectly in the simulation. Of course it won't work after building embedded target code because there are no equivalent c functions for mksqlite.

My plan is to rewrite all database operations to use S-functions but this causes problems. I know that RTWS can specify an initialisation function for the embedded target where i could open the database etc. but this wont work in the simulation.

how can i open my database in an initialisation function written in C which is executed in the simulation and the embedded target? is this possible?

regards,

Jan

I cannot comment on the task or feasibility to rewrite all database operations as S-functions. However, within a C-code S-function you can use the preprocessor symbol MATLAB_MEX_FILE to do host (simulation) and target specific things:

#ifdef MATLAB_MEX_FILE /* host/simulation */
/* simulation code, typically nothing */
#else /* target */
/* code to access I/O board */
#endif

So I would use this in the initialization part of your S-function.
