Hi Noor,
It is my understanding that you are working on Arduino and wants to know how to interpret existing Arduino code to Simulink s -function. S-Function builder block can be used to interpret the Arduino IDE Code to S-function.
In the properties window of S-Function builder add the necessary Arduino libraries and C++ S-function libraries under ‘libraries’ tab.
In the ‘Data Properties’ tab, under ‘Input ports’ add the required inputs and under ‘Output ports’ add the required outputs.
In the ‘Data Properties’ tab, under ‘parameters’ add parameter and specify the pin number in the Value field.
Use ‘Data type attributes’, to specify the data type for input and output ports.
‘Output’ tab corresponds to void loop() in Arduino IDE and ‘Update’ tab corresponds to void setup() in Arduino IDE.
