Hi
I am creating a function for the code generation using the targetlink . The aguments to the function are 1) non-constant, call-by-value (Normal Varlable)
2) non-constant, call-by-reference (Pointer variable)
These two inputs will be passed to the stateflow chart and and in the chart, Pointer variable will be assigned by a constant value.
When designed the stateflow like this, and run the model, the following error will appear: Chart Input data 'Pointer variable' on left hand side of an expression.
Please help me out to solve this problem.
With Regards
Dileep

Hi,
Stateflow doesn't support writing pointer variables, you have to use Custom C code. Please refer to the sample model here.
Thanks.
