Just checked back in here and noticed that the PS2 hardware forum is missing in action.

My question is what is required to make a decoder of a PS2 control pad?



Multigame used to make a PS2 to Vectrex adaptor that had many clever functions programmed into it.

I'd like to make something similar that takes a standard PS2 pad input and outputs the plain signal data for each point.


Thanks

There's been a LOT of info on PS1/PS2 controllers posted. I suggest starting with searching the forum.

Thank you for that most pertinent of tips - I performed a search before posting and didn't find anything that directly related to my question.

Do you have any keywords that might narrow the material down a bit? Found plenty about software/driver related stuff but nothing hardware based.

I've picked up a PS2 with a duff laser to have a look at how the controller port is wired inside the console and how the signal is chuffed around.

Any pointers would be appreciated.

There is tonnes of information on the net (and our forums) about the PS1/PS2 controller protocol. There are even a whole bunch of projects on the net using the PS1/PS2 controllers from a PIC or such, ranging from controlling a MIDI synth. to controlling a robot.

There are loads of pages like http://www.gamesx.com/controldata/psxcont/psxcont.htm which detail the protocol at a low level, so you can make a PIC or such drive it.

Hint: A PS2 pad will act like a PS1 pad until it's told not to, and even when it's in PS2 pad mode it still uses effectively the same protocol.

Here's another good doc that covers the extended pads you would have found searching here. I did since I lost the link... but five whole minutes searching here turned it up. :)
