How to simulate 8255 in proteus?

[dnlily2002]

Hi all:
I have a problem. I'm studying the MCU with the proteus and keil recently. Now I want to use the 8255 to extend the 8051's I/O, but I find the 8255 can't be active. What should I do? If I need a 8255's mdf file?


Please give me a reply!

Regards!

If You have V6 Proteus,you can find a *.dll file in models directory to run
simulations with 82XX without problems.
