Hi All,
I'm tiring to simulate a PWM circuit in Proteus, attached below. The problem is that simulation does not work. This is the message I get "Pin 'Cx' is not modelled". I'm new to Proteus. Thanks in advance.

Probably you didn't set the TRISC register to indicated if port C is an input or output.

No, every port is defined, but still I get this message after finishing the simulation....
