I am trying to simulate a PWM block using uVision2. I have my .cpp file(VC++ environment- in which I have the behaviour of PWM) and all the header files defined. When I compile it to get a DLL project - I get no errors. But when I test the same with a test code using uVision2 and the target as my DLL - I cannot see the output on debugging or any variables defined in my cpp files. When I try to see them in my watch window - i get "??????" what could be the solution to this? Thanks Regards, Ashish R. Dak
