I need some help converting some simple C code from an S-Function to a TLC file, but I'm not familiar with the syntax enough to do so. I'm not even sure if it can be done or not.
Here's the C code:
/* Function: mdlOutputs =======================================================*/
static void mdlOutputs(SimStruct *S, int_T tid)
{
union {real32_T x; uint8_T c[4];} sp;
real32_T *in;
uint8_T *out[4];
int_T i;
in = (real32_T *) ssGetInputPortSignal(S, 0);
sp.x = *in;
for (i=0; i<4; i++)
{
out[i] = (uint8_T *) ssGetOutputPortSignal(S, i);
*(out[i]) = sp.c[i];
}
}

请先登录，再回答此问题。

Figured it out...
%%File : sfun_Single2FourBytes.tlc
%%Description:
Real-Time Workshop interface for S-function "sfun_Single2FourBytes.c"
%implements sfun_Single2FourBytes "C"
%function Outputs(block, system) Output
/* S-Function "sfun_Single2FourBytes" Block: %<Name> */
%assign in = LibBlockInputSignal(0, "", "", 0)
{
union {real32_T x; uint8_T c[4];} sp;
sp.x = %<in>;
%foreach i = 4
%assign out = LibBlockOutputSignal(i, "", "", 0)
%<out> = sp.c[%<i>];
%endforeach
}
%endfunction
%%[EOF] sfun_Single2FourBytes.tlc
