Re: PWM module 1 and 2
Hi Lubin, well I do not have the exact model on me now, not that it is a secret, its not my own project. So I have made a simple model (attached), which will give an error described above. When I add another motor PWM module (#1), then it works fine. I would guess that there is something in the firs...

PWM module 1 and 2
Hello, We have experienced problems when using only second PWM module on dsPIC33fj128mc804. it does not compile correctly. Log is enclosed. When we added the first PWM module, it works fine. Another "bug" is when we use both modules and different periods: both generate constant PWM visible in worksp...
