A PlayStation Controller maybe just a little piece of electronic device with few electronic parts inside it, but the fact is, you can never play your e-games console without it. This device has only two basic functions; on and off. That’s right! If you have read any articles on electronics, you will know that Integrated circuits have those functions only. When you press on any of the buttons in your PlayStation Controller that sends a signal to the main processor telling it that such function is set to “ON”, thus, a specific action in your e-games are performed. Otherwise, you won’t see any actions performed on your screen.
Now, if you have an older version of PlayStation, its controllers will also work with PlayStation 2 e-games consoles but will never work on PlayStation 3. Likewise, PlayStation 2 controllers will also work for PlayStation but never on PS3. It is because; a specific IC is made to match its interface with the other. Thus, any incompatible IC’s can never communicate with each other.
The first two models of PlayStation have the same layout used in their controllers that’s why they also have the same functions when used interchangeably. However, PlayStation 3 has a really different circuit layout with a different IC used that is why controllers from the earlier versions cannot be interpreted by the main processor.
So, there is only one thing you must understand: if you are to buy a PlayStation Controller, you must first know the model of your PlayStation console.
