Inserting C Code in Simulink block

2 visualizzazioni (ultimi 30 giorni)
Hello;
I'm trying to learn how to insert C code in the user defined blocks of simulink, but I didn't have success.
I made this code in Code Composer Studio:
#include <stdio.h>
#include <math.h>
double y;
double u;
int main(void)
{
y=u*2;
return(y);
}
And I made this simple diagram
With this code in the matlab coder:
function y = callingmultiplicador(u)
%#codegen
y = 0.0;
y = coder.ceval('multiplicador',u);
But When i try to run, i obtain this error:
Warning c2_untitled.c: 180 missing prototype for multiplicador
Warning c2_untitled.c: 180 Missing prototype for 'multiplicador'
0 errors, 2 warnings
c2_untitled.obj .text: undefined reference to 'multiplicador'

Can you help to understand the problem???
Thanks

double multiplicador(double u) {
return 2.0*u;
}

Thanks that works, but now I try another test but I have a rare error, but I will open another question for it. Thanks again.
