Ok, I have seen some pretty crazy stuff when modding controllers (after all, I have only done 150 of them) but this sounds like a simple wiring problem. You have checked everything twice and all I can see for you to do is start over. Take off all the wires and the chip and completely start over.

I will post a pic of my controller set up and you can follow that, because your controller is just a plain mess.

Try hazers ideas first through (but I don't think its a hardware problem. If it was thinking it was a CG, don't you think the right trigger would always be on too?)

So if you have the supplies (you should always have spares) just do it again.

Yeah I have a lot of extra parts, like I said Im just a student right now, so I knew something might go wrong.
If you could you can just send me an email of the picture, I would like to see how a nice one it put together.
And did you use the same hex file Hazer put up on page 18 of this forum??

Ya that's the file I used. Like I said I will do it tomorrow. It is 12 o'clock where I am.

Good point. What this tells me is that the wire going from pin7 to the 330 ohm resistor to the middle wiper pin must be grounding out or disconnected. Normally for the Matrix controller, the PIC boots up and sees 1.5V on the right trigger and uses that to configure itself for matrix output. But what is happening here is that there is a disconnect and the PIC configures for a CG. That would explain why the aiming is stuttering without pressing the triggers. The reason why there is no rapidfire is because that output is disconnected/grounded before getting to the right wiper.

I think you might have solved it for me, maybe. When you say that PIN-7 should got to the 330-ohm resistor then to the right middle trigger pin. Dont you mean PIN-2????
 
When Im looking at you schmatics of the old-controller is the chip up-right, or is it on its back????

The chip in that picture is in the crawling or pin down position.  If you look at the chip from the top you will see a small dot on the chip that is pin1 (power pin). I am betting that you did it all backwards when you wired it up( i think i did my first one the same way) and got the same results as you are getting.

pics there.

Sorry Hazer, I just don't like the resistors. I don't know why I put the other pics there but I did. And that's only a third of my controllers.

Enjoy!

P.S. Get an A+ on that project.

Wow yours is clean looking compared to mine. Thanks a lot for the pics thats sweet, I have one question I see you soldered to a pin in the middle of the controller, what is that for??
 
And I should get an A+ on this one, I have spent well over the 33hours on it. Now I just have 3 more projects to think of and do....

Matt thanks alot that is what I did. Ahhh thats funny... Im still new to the whole digital electronics part of it all, our teacher just went over it a little bit but we cover it all in about two more quarters. Well thanks for the info.

It is another source for ground. I just use it when the other ground gets cluttered.

Hey Hazer. I am curious. Would it be possible to make a code that does exactly what this code does (press on off, hold to change) except make it specifically for the right trigger and only do 2 modes?

What I mean is, is is possible to make a version of this code that does not require the 10k resistor (you said the it is there because of controller type detection or something to do with the left trigger)?

I know I shouldn't say this, as it might change your mind about me BUT I would like to make a simple kit for people to install. Naturally, you are the first person I look too. Now, I really am trying to learn this stuff, but with business booming and all (40 sales in two weeks) and school (ya, I don't love to say it but I'm 15) I don't have much time to learn.

But really thanks for all of your help and I thought that I would let you know that the $6,000 I have earned in this business are going to my college education.


So thanks again Hazer.

Hey brianjoy77 Im going to upload a pic, I just want to know how you connected the bottom left tack switch. In the pic I put a light blue mark of where Im taling about. I just to know if you spliced the two wires or just connected them both to the tach switch lead??

I think I know what you are talking about.

First connect the 10k resistor from pin 1 to pin 4.

Then connect the power to pin 1.

Then connect the tact switch to pin 4.

Do this so that you have 2 wires soldered to pin 1 and 4.

I don't splice any wires. I solder them all to the chip, Hazers pic is a little confusing at first and I understand why you thought this.

So on the pic that you sent me, the notch of your chip is facing down, I mean pointing toward the bottom of the controller???

Yes the notch is facing toward the bottom.

What kind of new code are you trying to get??
 
 
And another question about your pic, the wire you run from the ground in the middle of the controller, where is it going??

I am trying to make a chip that is a little easier to install (read my post a few up). Also, I want to put in the sniper active reload for Gears (but Hazer said no, so its not that important to me).

As for the picture, the ground is going to pin 8 on the chip. The other ground is connected to the right and left buttons.

So you got the middle ground going to PIN-8, then from the ground on the bottom you have one wire going to one post on the right tack switch, and the other wire running to the post on the left tack switch????
Then with the other post from the right tack switch you run the wire from there to PIN-5, and from the other post on the left tack switch you run that to PIN-4?????
 
I think Im reading this right....
