Ok so I need to be able to swap the functions of Start and Select on my custom sticks via a DPDT rocker switch. Can anyone help me out as to how I go about it as I'm not sure how to wire it up. I have an idea but I need it confirmed. A diagram would be great.

Thanx.

Custom sticks don't need +5V, unless you want to use it for something fancy like lights, autofire or optical stick. If you plan on using a NGCD pad in your supergun you need 5V in pin 8 of the supergun's controller port.

In any case, be warned that if you use pin 8 for a coin button and hook the controller to a machine that has 5V in pin 8 (like the AES and MVS controller ports), if you press that coin button there will be a short between 5V and ground and your system will reset, which may damage it. I would leave pin 8 empty if I were you.

Just a guess, but the CD pad uses a PCB (and from what I remember a few chips), so maybe some of the components need the 5V to work properly.

The old style pad is just buttons.

Thanx Dani. My MVS board will be fine as it no longer has Pin 8 in the control ports. I plan to never use CD sticks or pads with the board so the pin will not be missed.

Which bit are you stuck with? and do you mean have one button for both functions or two buttons on each stick and you want to flip them over?

I have Start and Select. I want to be able to flip the rocker so they become Select and Start. I think I have to wire it like below, but I'm unsure.


Start Start Select
Select Select Start


Left will give me Start and Select and right will give me Select and Start right?

Yes, that's correct.

Ok cool, so should I wire it with 2 wires from each terminal on the buttons or chain the wires at the terminals on the rocker switch?

reading this, I am not sure what you want really....



you want to swap the functions of the buttons?


one button that needs to work for both with a switch?


two buttons that you want to swap back and forth from controller to controller?

I have a stick, it has 2 buttons. One is Select, one is Start. Just like a Neo stick or a PS2 pad.

Looks like this:

Select, Start.

I want to wire the rocker switch so I can make them swap around like this:

Start, Select.

Then when I switch it back it'll revert to:

Select, Start.


I have a good idea about how to do it, I just need to know whether I should run 2 cables from each button terminal to each rocker terminal or one cable from each button terminal and then chain it to the other terminal on the rocker switch?

If it were me, I would hook it up like this and have the on/on rockers on the back of the sticks. yeah, the pic sucks, but ot will work.

grounds don't matter. hook 'em all together.


wire the buttons to the middle, start on top and select on bottom.
wire the select to the top left, then chain that to the bottom right.
wire the start to the top right, then chain that to the bottom left.


I remember this from when I made a switch to switch button configs on my arcade panel.

Okay, so I'm having a bit of a problem now. One stick works fine, I can swap the functions of the Start and Select buttons with the rocker.

Rocker left: Start and Select.
Rocker right: Select and Start.


The other stick is funny, the rocker either makes the Start button work or the Select button work, but not both at the same time and does not swap the functions.

Rocker left: No Start and Select.
Rocker right: Start and No Select.

It's wired exactly the same as the first stick. I've checked it several times and I just cannot understand why it is doing this. The only thing I can think of is that the rocker switches are different, but they were both bought at the same time and are apparently both the same model of ON/ON. I'm thinking one might be faulty?

Can anybody offer any help as it's driving me mad.
:help:

If you are positive that the wiring is identical, then the switch is bad. I think about half the DPDT rockers I have bought in my life have had problems...

I would follow NGT's ever so nice artistic representation above :chimp: It's pretty straightforward once you realize that the start and select buttons in his picture are actually about 1/10th the size of the rocker switch and he didn't just ground the middle pins which was what I originally thought the pic represented.

cheers,

fekkers? Hmmm

Its multi-meter time. time to check everything out to see if it works, continuity tests all around to make sure the toggle switch is behaving as you expect, and also to verify the wiring/soldering. If the switch was to swap the start and select functionality of the buttons, and start works one way, and select works the other way, logic says that means only one pushbutton is working. I'd double check the toggle switch first, then check the pushbuttons to make sure they both work, and check the wiring around.

One thing you didn't mention was what kind of pcb you're using in this stick. Remote possibility of oddball ground issues with crappy third party pcb's. But my gut instinct: bad pushbotton or wiring to the button. Only some time with a multimeter will tell you exactly where.

Ok so I was actually wrong. What happens now is this. Remember there are two buttons like this: Select-> [] [] <-Start. Only the right "start" button functions now, the left "select" button does nothing.

Rocker Left: Button=Select.
Rocker Right: Button=Start.

I've checked the wiring and it is exactly the same as the first stick. Both the buttons work when you take the rocker switch away, so none of them are broke, but the circuit is not behaving in the way I want it to.
The PCB/stick is a Hori Fighting Stick PS. I am leaning towards a faulty rocker. I shall pick up another few and try those I guess, after I get busy with the multimeter. Thanx for the help. I shall post back if I still have problems.
