[Stick-Building Question] Can't Wire Triggers


#1

TL;DR I need to find a way to wire the Afterglow 360 triggers to my arcade stick buttons.

When I was building my arcade stick, I have a problem wiring the analog 360 triggers to the digital buttons. They’re properly wired with the ground at the bottom and the second wire in the middle, but every time I press one of the buttons (in this case, the left trigger), it will move the z-axis down all the way, and then slowly move it back up to the center in about 6 seconds. Same thing for the right trigger, only it moves all the way to the right and to the center.

And I saw a video recently that I thought would be the answer: http://youtu.be/9Km1P4wM480

It said to use a resister and then wire the buttons which I thought would work, but once I did that, I had the same problem, where the axis would move down and up, etc. I have no idea if it’s because I’m using a third-party controller (The Afterglow Gamepad for Xbox 360) or if it’s wired wrong, or both. This has been bugging me for weeks, and I’m desperately trying to find an answer, so any help would be greatly appreciated.

Many thanks in advance!

With something like this , we need to see pictures of your wiring and how you inverted your triggers.

Okay, I’ll try to get as detailed as possible.

Let me know you you need any more pictures.

Yeah, that’s generally not how to wire triggers on a padhack.
You need to neutralize the analog part.

Basically, you have 3 contact points on the analog trigger: V, Signal, G.
You need to solder a 10kOhm resistor between **V **and Signal, and a second 10kOhm resistor between **Signal **and G.
Then you solder your wire from your pushbutton to Signal.

Sorry I took so long to get back to this, but I finally got around to wiring it. So we wired the stick just like you said and it worked! Now the triggers are acting just like normal buttons. I only have two minor problems with it now:

  1. When I press both triggers at the same time, they stop working. However, pressing one button at a time works. This is my most minor problem, because I barely use these buttons in games, but a fix would be nice.
  2. In some smaller indie games like Skullgirls and Jamestown, the deadzone on the triggers are not far enough for the game to register them as buttons. However, AAA games like SSFIV AE and MK9 aren’t nearly as picky and they register properly.

Other than that, it works great! A solution to both of those problems is greatly appreciated, but if there is none, I can live with what I got!

What you should do is plug them into a PC, and check out the behavior in your Devices and Printers.
You should be getting a window that looks like this:

From there, you should be able to see what goes on:

  1. The Z-axis bar on top should go all the way to the left when you press RT and all the way to the right when you press LT. Pressing both should keep the bar centered
  2. I don’t see how games would not register it, but I unfortunately don’t own either of those indie games; with the trigger hack with the resistors, you’re basically setting the triggers to be “unpressed” when your button is not pressed, and “pressed all the way” when you press your button. Unless those game specifically require hitting a midpoint in the analog part? I don’t think I can help you on that one.

Okay, so I’m supposed to be pressing the triggers all the way when I press the button? On my z-axis it’s only going down/up about halfway. However, I’ve found a solution. I just calibrate the controls in the settings tab, and now they’re pressed down all of the way. It even saves the settings I want when I apply them. So ya, I think that’s settled. Thank you so much for your help guys!
