Re: DSPIC33FJ32MC204 SIMULINK : the scope doesn't work.
Set the duration to 1 sample in the External signal & triggering panel. (currently set to 10000). Otherwise, the model is likely to store 10000 samples before sending them all. (don't you get an error message in the diagnostic windows about a possible "out of memory" error ?)
Provided the model is set with a 1s time step, that might take 3 hours before you see anything !
Could you try setting a faster time step (in the Model solver configuration panel) ; I would try at least 10 times faster with a 100ms time step (if not 100 times faster).
Is the numerical display working ?
