    this site shows the pin layout of the psp vs a regular analog stick, and how to connect an analog stick to the psp. Since the negcon has only three pins for the turn, where would these three wires be connected to from the negcon potentiometer?
    It's the same as a Stick, the neGcon just has the X-Axis (left/right) where the Stick has and X-Axis (left/right) and Y-Axis (up/down), so you'd just connect it to the spots the X-axis of the Stick are using, which going by that diagram is A/B/C, with B being the Wiper (center pin) then A and C being power/ground, and if ya get the power/ground backwards it'll just work backwards is all and swapping them will fix it.

    xbox negcon now is a reality. I wish I had the thrustmaster wheel for it, but I ended up just using the yamaha motorcycle wheel that was made for it (kinda). The yamaha wheel comes with a controller converter for xbox/gamecube, and has sensitivity settings, although with this game, I would rather have it perform like it does on the other wheel, set at 45 degrees. Anyway, I think this will work well when I get used to it.

    IH8you, I was wondering how the one you were making was working out?

    Default Oh yeah!

    I've just succeeded in building a microcontroller-based circuit that allows me to use an unmodified negcon on the ps3. I'm pretty pleased as I've spent practically every spare moment for the last three weeks trying to figure this out!

    At the moment it only works on full sensitivity. This should be trivial to code a solution for, but I'd like to use a potentiometer to calibrate sensitivity so as I have to learn ADC routines for the controller it might take a little while to get right! Also, only the twist is analog. I think I should be able to get the other buttons analog but it's not a priority as I've never used them that way. Likewise the lack of home button.

    quick picture: (my camera is ) http://www.wipeoutzone.com/forum/alb...pictureid=2081

    more details to follow!

    That sounds very promising. An analogue option would be good, but I'm not sure about analogue buttons for WipEout HD. With the sideshifts and barrel rolls, I think digital would work better. So perhaps full analogue is not a necessity for HD but may be for the other games.

    You guys are genius ! You should use Webex and cooperate among all of you and maybe this could be financed one day?
    I had chance to get into my hands Al's HD Neg V1.0, i sent it back to him to get the new V2.0

    Special greetings to you Element42, Mister Mo(lybdenum). great to see back an old Neggie lover

    More progress, have successfully added potentiometer for calibration, as well as some push switches to map the buttons not on the negcon (L2, L3, R2, R3 & select). I have attempted the home button and analog buttons but no success... actually, I could use a little help here.
    I need to see some HID reports for other PS3 devices. An HID report is a little chunk of code that tells a host device exactly what a USB peripheral is and can do. I managed to get my adaptor working after essentially copying the report from a standard PSX -> USB adaptor. If I'm going to get the home and analog buttons working, I think I'm going to need to see the HID report of something else with a home button and analog buttons! The Sixaxis/dualshock3 has a report that is very complicated so ideally what I want is a report from a steering wheel with analog throttle & brake (like the Arno-con! which presumably maps the analog buttons), and a PS3 adaptor something like this:
    http://www.wipeoutzone.com/forum/alb...pictureid=2084
    That's a PS3 adaptor that will take a PSX controller and a PSX memory card. Unfortunately mine doesn't work! But importantly it has a home button.


    So, how do you find out the HID report?
    1. Install USBlyzer (trial version) from http://www.usblyzer.com/download.htm
    2. plug in the gamepad to the computer.
    3. Install & open the program
    4. In the top-left panel (device tree) click on the port that is directly above the gamepad (should say something like Port x: USB human interface device)
    5. In the bottom-left panel, scroll down to the bottom section (Interface x: HID report descriptor). This should begin with something like "Usage Page (generic desktop) 05 01'. Select to the bottom, copy and paste into notepad or something.
    6. It would also be useful if you could go to Control Panel -> Game Controllers -> Properties and find out which button number lights up when your press the home button.
    7. Shoot me a PM with the info!
    Right, that's all for now. The home & analog buttons are really just a software issue so I can get on with some stripboard soldering to properly 'make' this thing...
