I wish to use the "Arduino Support for Simulink" to write code in Simulink and use it on an Arduino. But, I need to be able to incorporate interrupts in order to read the output from a quadrature encoder. Does Simulink support this? If not is there a way to access the sketch file before it is complied to add some more functionality that Simulink is lacking?

If you mean that you want to gey the encoder info i.e(speed,steps) you can do that in simulink without using interrupts refer to the built in example in the arduino support packages examples named ( Driving car with PID controller )

I assume you are referring to the Run on Target Hardware support for Arduino.
There is currently no support for working with Arduino interrupts from within Simulink. If you have Embedded Coder, you can access the generated code (the sketch) before it is compiled. Otherwise (if you just have Simulink) there is no way to access the generated code.

Hi I want to use this interrupt block to detect a change and then read whether the voltage is high or low. But I am unable to do that

Hi,Gautam Vallabha : I want to create a interrupt block of Arduino. Can you give an example to me about what you wrote " If you have Embedded Coder, you can access the generated code (the sketch) before it is compiled. "
thanks very much!

Dear Curtis,
you can check out that entry on the FileExchange LINK. You can use the template for creating custom S-function blocks.
Cheers Christoph
