New Version of Wireless Controller Board, CG, Looky what M$ did... Options

[jonobot]

wow i was way off then... sorry for posting such a poor effort but i was just a tad impatient and thought id have a pop.

1)so all the grounds on A,B,X,Y(and LB,RB) can get wired together and brought down to tp2 or tp22?

2)Ill check up on the triggers but its a 10k resistor between 1-3 and 2 is ground is connected to ground on the button and 1 is the signal?

3)when i daisy chain the grounds on joysticks micro switches do i connect them to tp2 or tp22?

thanks for the help. if I'm rite with those questions i think i can start trying to wire it up.


cheers.

You're still a bit confused.

1) Correct. All of the buttons share that common ground, D-pad, ABXY, LB/RB, LSC/RSC, Back, Guide, Start and Sync.

2) The 10k Resistor goes between 1 and 3. Ya are hung up on the ground here for some reason though, forget all about that as 3 is really the ground on the CG version controller, it's backwards of how the other 3 are, so 2 is really voltage. Just wire it up like the other controller are, not how the ground/signal gets wired up. 1 -Resistor- 3 and then 1 -button- 2.

3) TP2 and TP22 are the same, so take yer pick or use them both.

thanks man. You are god.

i've spent past 3 days searching the web and was just getting confused about the triggers and where the grounds go. Well seems like i can have a good effort at it now then maybe try some of the other funky mods on this site. Never even knew half the stuff on here existed.

Many thanks again.

So i have followed this tutorial to the T and have worked on two boards with no issues. Now that I'm working on my PCB I'm having an issue. I have removed the triggers/thumb sticks, I have placed the resistors on the triggers where they go, but for the Thumbsticks I lost one of my resistors so I'm only running 3 instead of four, also know I had to use the back VIA's for my D-Pad because I messed up some of the contacts in the front. Well here is my issue, I have tested all my buttons and all worked but one. When I go left, it thinks I'm pressing Down on the D-Pad. I have looked at the PCB's posted by RDC here over and over, and it is where it is supposed to go, it is not touching any other contacts. Any help would be appreciated.

Thanks

If everything else is indeed correct and it's a CG version board ya shouldn't be having an issue like that. Having only 3 Resistors is making it so the stick is pointing in one direction all the time though, ya need to fix that first and then see how it works.

Will do.

[djorijun]

Will do.

Okay RDC,
So I went ahead and added the resistor. Still goes down when I press the DL on the rear VIA. I followed it to the chip as you have displayed below and it still went down instead of left, I also touched the one to the right of it and it also went down. I have a feeling that one is down for the Dpad and the other is down for the thumbstick. So I have a feeling that this trace is incorrect. Can you please give me a hand with this? Thanks
I circled the one you say is left on the DPAD and that is where I have soldered on to.

Sorry, but everything on that diagram is 110% correct. On top of having made them up I actually use them, because crap all if I'm remembering all that stuff, even though I pretty much have anyway, and I've never had any issues. Also the X/Y axis for the sticks are on the other side of the chip, so if yer getting the controller acting like that ya either have something seriously wired up wrong or a screwed up controller IC.

I believe what you're saying so I guess I have something wired wrong. Would you happen to have any ideas what it could be? I ask you because you are the pro, I was just saying what I've tried that way you can give me the advice as you have. Please don't take it the wrong way. Also the X/Y axis has the resistors required.

[RDC]

Without seeing what ya did to it it's hard to even guess, but something for sure isn't wired right, crossed or who knows what kinda damage done from tearing up the spots on the front and just messing with the board in general.

If it was a short on the DD and DL lines I'd expect it to move down and left at the same time no matter which one ya pressed, which is the same thing as pressing down/left diagonally, but since it's only moving down that's not possible.


There's nothing that I know of that will cause the controller to move down when left is pressed, it's a common Ground controller, so the only thing common there between those 2 things is ground, each direction has it's own line, so it's really impossible for one to do the other unless something is really screwed up somewhere.

This still confuses me. So if I want to add extra A and B buttons, I can scrape the top of the board at the correct point and solder to that? And where will the other side of the button be soldered to? I know's there's a CG but where would be the best/right place to solder A and B, or even with X and Y???

Please help, thank you!

Ground is ground, you can use any spot for that connection, TP2 and TP22 on the back side of the board are real good ones for that. As for the A and B vias to use, be VERY careful scraping them down and soldering the wire to them, if they get messed up it would be a real witch to fix that thing back up so it worked again.

Green is A, Red is B


No, if you connect the Base of the Transistor to ground it'll be on all the time and a 10k or so Resistor should be used between the Base and Emitter leads to make sure it stays off when it's not used, and unless you leave the Triggers installed yes a 10k will still need to be installed there as well. You want the Base lead to be wired to whatever button you're going to press that ya want to be the Trigger, so when that button is pressed THEN the Base is connected to ground, are ya pickin up what I'm layin down? Any small signal type PNP Transistor will do, it's just being used as a switch.

and is it necessary to put a resister in between the button and ground? What would happen if I didn't. All I want to do is add extra buttons

[RDC]

Have ya bothered to read any of this thread? or even that post ya quoted from? Since the answer is no, because if it were you'd know where the other side of every button goes, it's Ground, the G in the CG, C is for Common, as in shared by more than one. The best places to use for the Ground spots are right there in that post ya quoted also, TP2/TP22. All of the lines are traced out in the first couple pages of this thread if ya need to know where X/Y or any others are, specifically post #19.

The buttons don't need Resistors on them, only the Triggers do and only if they're removed, again has been covered before, so not putting them on there is exactly what ya need to do.

After kinda destroying a controller I actually understand a bit now. I scratched too hard into the board because my solder wasn't sticking. It was actually the B track so I'm gonna have to reroute it myself to rejoin the track :-S

Or alteratively scratch away at the button pads... but this will leave the normal buttons useless...

So the best way for adding an extra button, I need to scratch away at one of the little circles to expose the copper yeah? Solder to that right. Does anyone have any tips on soldering to such a tiny point becasue I don't want to risk messing up this controller any more.

Cheers guys

Good luck, fixing a mistake is always more difficult than doing it right the first time. Depending on how damaged it is there you're only option may be to solder to the leg of the IC, much more difficult than soldering to a trace.

Practice, then practice some more, then when ya can do that type of thing without damaging it, practice one more time to make sure it wasn't a fluke and ya know ya can pull it off. Read the Trace Repair threads in the Tutorials section also.
