Playstation 2 gamepad controller

[coldfire]

Hi All,

Anyone know how to interface Playstation 2 gamepad to PIC16 to robotic control? Thank you.

Regards

Have a peep  at these:


h**p://sophiateam.undrgnd.free.fr/psx/index.html

and

h**p://users.ece.gatech.edu/~hamblen/489X/f04proj/USB_PSX/psx_protocol.html

and I haven't tested this

Code:

This example is incomplete.

I made a pad with Freescale GT16 using DS2 dual Schock protocol.

And are you willing to help us indicating what is wrong with it ?
At first glance , I understand the BASIC code given is reading only the first value. Is it so ?

OK
The pad of the PS2 has some of 16 frames of command to adjust mode of operation.
Each frame has 8 bytes around with the method of configuration.
What is the site shows only the frame after programming the pad.
This is a first frame for Need for Speed Underground
