Hi, I'm generating a driver to generate C code, and I need to pass one string from mask to the generated code. Is possible to pass this string from Simulink, with S-function or mytlc.tlc? I have thought that I can pass a string collecting the block name from mytlc.tlc, but it isn't the correct form. Thanks in advance

Yes, I think this should be possible if you register the parameter as nontunable. You will need to implement the mdlRTW method in the S-function and write the parameter using ssWriteRTWParamSettings - the TLC file can access its value from the SFcnParamSettings record . Also, uncheck the "Evaluate" box for the parameter on the Mask .

I dont think this works. I'm missing something trivial, can you please help
S-Function CODE SNIPPET
#define MASK_PARAM_NAME1(S) ssGetSFcnParam(S,1)
#define MASK_PARAM_NAME2(S) ssGetSFcnParam(S,2)
#define MDL_RTW
static void mdlRTW ( SimStruct * S )
{
const char_T *testTLCStr = "maskParam1TLCName";
const char_T *maskParam1TLCName = (const char_T *) (mxGetData(MASK_PARAM_NAME1(S)));
const char_T *maskParam2TLCName = (const char_T *) (mxGetData(MASK_PARAM_NAME2(S)));
if (!ssWriteRTWParamSettings(S, 2,
SSWRITE_VALUE_QSTR,
"maskParam1Name",
testTLCStr,
SSWRITE_VALUE_STR,
"maskParam2Name",
maskParam2TLCName)) {
return; /* An error occurred which will be reported by SL */
}
ssWriteRTWStrParam(S, "maskParam1NewTLCName", maskParam1TLCName);
}
Mask Parameter 1 is
'maskParam1TLCName'
Mask Parameter 2 is
'maskParam2TLCName'
TLC CODE SNIPPET
%assign maskParam1TLCName = SFcnParamSettings.maskParam1Name
%assign maskParam2TLCName = SFcnParamSettings.maskParam2Name
testStringFromMaskFcn( (uint32_T*)&%<maskParam1TLCName>,
(uint32_T*)&%<maskParam2TLCName> );
testStringFromMaskFcn( (uint32_T*)&%<maskParam1TLCName>,
(uint32_T*)"%<maskParam1NewTLCName>");
AUTO GEN CODE SNIPPET
testStringFromMaskFcn( (uint32_T*)&maskParam1TLCName,
(uint32_T*)&);
testStringFromMaskFcn( (uint32_T*)"m",
(uint32_T*)&);
In the above ssWriteRTWParamSettings case only testTLCStr goes through in the form of a string to auto-gen code however maskParam1TLCName and maskParam2TLCName do not go through.
Also in case of ssWriteRTWStrParam only the first character of maskParam1TLCName goes through to auto-gen code

yup! This method works! I successfully pass in string variable using Edit UI. Then, retrieve the string parameter in using TLC file (Code generation)
