How to pass simulation context into Scilab C block?

I have been developing my own function block in Scilab/Xcos on the C block basis and I have been struggling with passing parameters defined in the simulation context into the C code. Does anybody know how to do that? Thanks in advance for any ideas.

How to set parameters in Scilab blocks from SciPad?

I don't know if anyone faced the same problem! In MATLAB, we can easily set the parameters of Simulink blocks from m-files. For example, we can change the coefficients of transfer functions, PID gains, step-input magnitude, simulation time, etc. In…

Global variables Xcos

I am new to Xcos. Is there a way for a block to read or write to a variable that other blocks could also access? or if there is a work around to achieving the same. Thanks

Porting xcos from 5.5.2 to 6.0.1

Opening xcos drawn in 5.5.2 using 6.0.2 results in blank pages. There are no special import functions I can find in the 6.0 help. There are no white papers I've found yet on the scilab website. I suspect that since 6.0 was a substantial rewrite…
