    Just got my RM-X2S found on Yahoo Auction a few days ago....
    Now I use the RM-X2S, Rockfire RM-203 Gameport to USB adaptor, the self-made adaptor, WINAMP 5 and the plug-in posted by Curiosity.... It worked!!

    Love you guys.... Hopefully, there will be a application/driver for using this in all Windows programs (maybe like hot-keys)....

    I am also looking for usb solution (EPIA). Would any gamepad work or need one with the analog sticks? what about a ps usb converter like this here http://www.lik-sang.com/info.php?pro...ikref=froogle2

    I am trying to connect from my car's OEM steering wheel control which also use varible resistance. I read thru the thread and it seems I will need resistors? I am not good in electronic, how do I know if I will need to use resistor and how should it be used?

    Here's the voltage output from car's steering wheel control

    What's "Except for above" mean? Is that what you get when no buttons are pressed? And where does the 5V come from? If the source is still there without the HU connected, you may not need any resistors. Not sure about the PS2 thing though. If you can find a pinout of the PS2 connector, that would help.

    I am basically trying to follow God_of_cpu's method (we both have the same car).



    The only different is that my EPIA board doesn't have gameport therefore I need a usb solution. In GOC's thread, other G35 drivers says the RadioShack USB -> Gameport adapter doesn't work. People say I can try to use a analog stick joypad but the problem is that it is too big. It seems that a Playstation pad -> USB adapter is cheaper and smaller. The description says it can connect both digital and analog PS joypad so I assume it has the digital converter build-in? I am really not sure so that's why I asked. Plus I am total noob when it comes to electronic and reading schmetic.

    The Radio Shack one is definitely hard to work with, but I have gotten it to work... half the time. The PS2 one won't work either, unless you connect a gamepad and hack into it. I just looked it up. The analog convertor is on the chip in the gamepad. That's why that adapter is so cheap. All it does is convert PSX data to USB. So I guess a USB gamepad is the best choice still, other than making a custom USB device and software or buying an expensive analog reader.

    Thanks Curiosity for looking up that PS/USB adapter for me. Now I just need to find a small and cheap USB gamepad.

    I got a logictech wingman gamepad. There are two PCBs inside: the main boad that house directional and push buttons, and then a smaller board that holds the analog control. There is a ribbon (5 wires) to connect between the two board.

    Here's a pic of the analog control board (front/back)


    I a bit confuse on how should I connect this because I dont understand how the analog stick works. I assume it is using variable resistance thus when I move the sticks I should get different voltage reading when measuring the input pins, am I correct?

    Well, I test this using a multimeter. I connect one end to the usb cable connector on the main game board. It is connect to the black wire from usb cable (there two black wires, one red, white and green). I then connect the other end of the multimeter to one of the input pins and I got 4.86v. I moved the stick around and I still get constant 4.86v? But in window's gamepad testing properties I can see the axis being move around.

    Am I measuring it incorrectly? Interestingly, when I measure between +5v and the input pins then I get different reading. As I moved the stick from left to right I get a reading of 0.01v to 0.05v. What does it mean? Also, as u can see on the analog stick board it is using some 10kOhm resistors, does this explain the 0.01v ~ 0.05v reading that I am getting?

    how should I connect SWC to this? thanks

    Oh, that's odd. The one I have has a 6 wire ribbon, and has 5V and ground going to all the pots. That should still work though. I think the reason you see such low voltage is because of the 10k resistor plus the load of the input dropping it down. First, are you going to use your HU or just disconnect it from your SWC? If you disconnect it, there shouldn't be any power going to it. You might want to test that anyway, to make sure. Just connect black to metal on your car and touch each wire of the SWC with red, using volts and ohms to make sure nothing is grounded either. I think pin 25 is ground? If it's all good, you should be safe. You may need to pull those 10k resistors off and connect them all between 5V and the input wires (5v-pin2, 5v-pin3, 5v-pin4, 5v-pin5), then connect to the SWC: pin4 to pin 22, pin5 to pin 23, and ground off the main board to pin 25. If that doesn't give you different values in the joystick config, you'll need different resistors.

    Thanks again Curiosity,

    Wire #25 from SWC is in fact a ground, my car works in reverse where it is suppling ground. I will be using a relay in GOC's desgin to switch between suppling ground or +5v to pin #25 of SWC. In carputer mode it will supply +5v to #25, in headunit mode it will supply ground.

    My problem is not able to understand how the gamepad works. May be someone more knowledgable can explain to me...



    -Here's my understanding...
    A - What is this? Is it suppose to be ground?
    B - I understand this is the input for the axis and it shoud output vairable voltage based on the position of the stick, right?
    C - I suppose this is the power. Since there's a 10k resistor in the path, the voltage measurement I get from here should be 0.05v max, correct?

    Well, when I test this with multimeter the result totally confused me.

    I connect the black probe of the multimeter to the USB cable-inlet's black wire. I suppose that is the ground. I then connect the red probe to point A and I get a reading of 4.65v. If A is suppose to be ground then this should be 0v right? The voltage reading between ground to B or C is constant 4.86v regardless of the position of the stick. Also, isn't the 10k resistor suppose to limit the voltage reading at point C to something like 0.04v rather then 4.86v?

    Just ignore point A. On most gamepads that's connected to ground, but it's just free there. There's probably a resistor on the main board that connects between the input and ground pulling it down some. Point C is the supply voltage which shouldn't change, and point B is the ADC reading voltage. That should really change. The ADC is basically just a voltmeter with a range of 0 - 5v or maybe in this case, it's more like 0 - 1v.
