Using the C2000 blockset with an F28379D. I have a subsystem block that I call with an interrupt (an ADC block).
--> What I want to do is create a "counter" variable in the subsystem, where this counter increments itself by 1 every time the interrupt is called. This way, I can view this variable in Data Inspector to see how often the interrupt is called. Is there an example that shows how to do this?

I think you can try this block. Put it inside the Subsystem and specify the sample time as -1, which inherits the interrupt.
