help with how to swap up axis with down axis requested

I made a converter to convert the 'plane' mode of the CH Pedals from joystick 2 x-axis left and right to joystick 1 y-axis up and down (like the t2 pedals). My problem is the accelerator is joy1 y-axis down and the brake is joy1 y-axis up, opposite of the t2 pedals. This is fine for games like CPR (swap pedals), N2, and GP2. But for games like ABC indy racing, Monter Truck Madness, and I think TOCA, the accelerator must be the joy1 y-axis up. How do I rewire the pedals to make the accelerator joy1 y-axis up and the brake joy1 y-axis down? -Jeff

You can't re-wire them, but you might be able to mechanically reverse the potentiometers in them. The way the joystick works is that increased (electrical) resistance is "higher" numbers and decreased resistance is "lower" numbers. There is no simple electrical change you can make to reverse them. If you can turn the pots around (or the mechanical linkage driving them), you will make them reverse their direction of highest resistance and with the same wiring as now, it will work in games from less forward-thinking manufacturers. There are also no doubt active electronic circuits that you could build that would accomplish this trick, but they're beyond the scope of mere mortals. :-) The other obvious alternative (for the patient) is to report the inability to configure the controls to your setup as a bug, return the game to the store, and refer those game manufacturers to the fine traditions handed down by their fore-fathers as examples of how to fix their bug. ---Jim

I was playing around with reading joysicks recently and it amazes me that anyone could guess right the first time about the direction when programming it. ;) (OK, maybe they read the manuals first ;);) When I decided to swap 2 of my four axes, I went ahead and put configurable axis swapping in for all of them ;) - Matt

Since I decided to use the CH Pedals for auto sims only, I disconnected all the wires from the pots and directly swapped those from the acclerator with the brake unit and vice versa. This would mean that I would be unable to use the unit for flight sims though. Doesn't matter to me since I also fiddled with the spring tension. I fitted 4 springs, yup 4, into the brake pedal. I mounted a metal bracket on each end of the spring mounts that could fit two springs for similar type to the standard spring and two smaller springs (the whole idea being to fill the pedal with springs). On the acclerator unit, I swapped the standard spring for a weaker unit which I had made at a local spring shop. It all works great so far. Next up would be perhaps to add a hydraulic piston to the brake unit for better `feel' Stanley

If you have standard off-the-shelf pots in the pedals (three wires), you can move one of the wires on both pots to get what you want. UAA (Ugly Ascii Art) follows: (view with a monospaced font obviously) Pot: +v^v^v^v^v^v^v^v^v^+ | ^ | | | | 1 <-2-> 3 The resistance across pins one and three is constant, and is equal to the sum of the resistance from pin 1-2 and 2-3. Pin 2 is connected to the movable wiper in the pot, which allows the resistances from 1-2 to be varied. So, if a pot is currently wired to pins 1 & 2, move it to pins 2 & 3 and vice versa. Sorry about the brain-fade, ---Jim PS: Of course, IMO it's still a bug in games that don't allow for proper controller configuration.

Sorry, to say it, but you're wrong, Jim. He just has to switch two wires on each pot. On one there are only two, so just switch them. This is of course only necessary for games that HARDCODE the joystick action for gas and brake (up and down, that is). l8er ronny -- |\ _,,,---,,_ I want to die like my Grandfather, ZZZzz /,`.-'`' -. ;-;;,_ in his sleep. |,4- ) )-,_. ,\ ( `'-' Not like the people in his car, '---''(_/--' `-'\_) screaming their heads off!
