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 program reads the Sony Play Station 2 game controller data.
'Omer Yildiz Dec. 05; [email protected]


@ DEVICE intrc_osc, MCLR_OFF,WDT_OFF,PROTECT_OFF

TRISB = %01000111
TRISA = %00100000

DEFINE LCD_EREG PORTA   ' Set LCD Enable port
DEFINE LCD_EBIT 7       ' Set LCD Enable bit

dat var portb.6 ' Play Station game controller connections.
cmd var portb.7
att var portb.5
clk var portb.4

psxdata VAR Byte[7] ' Variable definitions.

start: 
' The first shiftin gets the mode. (73)
' The next 2 shiftins gets the pushbutton data.
' The next 4 shiftins gets the analog joystick data.

    LOW att
    SHIFTOUT CMD,CLK,0,[$1\8,$42\8] ' Initiate request for data from PSX controller.
    SHIFTIN DAT,CLK,3,[psxdata[0]\8,psxdata[1]\8,psxdata[2]\8,psxdata[3]\8,psxdata[4]\8,psxdata[5]\8,psxdata[6]\8] ' This is the Mode value, it will be dumped.
    HIGH att

        LCDOUT $fe, 1,   #psxdata[3],",",#psxdata[5],",",#psxdata[1]      'see what is changing...
        LCDOUT $fe, $c0, #psxdata[4],",",#psxdata[6],",",#psxdata[2]

    pause 10

goto start

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
