That's becos your buzzer is connected at the wrong place.

At the wrong place? That's weird. I'm sure 1 pin is connected that the VCC and the other is connected to the 1k resistor.

Anyways, do you know is there are any virtual HCS12?

Your last schematic


According to your schematic, if you move your buzzer from RCx to J3 then it would function correctly.

What is HCS12?

I believe that the HCS12 is the Freescale 68HC12 if I'm not mistaken.

Yeah. I think it's called Dragon Board for micro-processor subject.

Never used the Motorola HC12 before. But I have the HC11 SBC from New Micro Inc

The simulator for HC12 is here
But Proteus doesnt emulate HC12 anyway.

It's not for Proteus. It's for my mini project. That's all.

Thanks for your help
