It comes from you pressing it.  The B button line runs straight to the MCU, U1p81. Schematic and even that button line is traced out in the first post.

Hello, the B button on my 1537 controller doesn't work, after a closer look I see that it gives no signal at all. Does anyone know where the B button signal comes from?

Good afternoon, please tell me the correct polarity! The gamepad is lying on the table with the sticks facing up.
1 - ground
2 - 5v
3 - resistor between the 2nd contact at 5.6kOhm, is everything correct?

That's what I experienced too...the xbox controller problem after changing the stick 3 times with different models and it still does the same thing....I still haven't found the solution. https://www.youtube.com/shorts/DFb8nQFKxvc?si=reYXpWrOKY8CggyK

Hello, I have a problem with a BDM-20 motherboard. It doesn't start, nor is it detected. When I plug the cable into it, it makes two orange flashes and that's it, it doesn't detect the cable either: I changed the battery with a new one, checked the input connector if it is firmly attached to the board...has anyone else encountered this problem? thx
Has anyone encountered this problem?

I have another problem, I changed the left stick, recalibrated, everything is fine. After 10 minutes it started to pull down, when I push it down it goes up....do you have any idea why? I have two boards that do the same thing and with different models of special xbox sticks

Ended up deciding against the faking touchpad thing. I was initially wanting to do it so that I can send ultra specific locations of the touchpad via buttons connected to a microcontroller, so that remapping software on PC can differentiate those ultra specific locations and normal touchpad touches. This way I can get extra buttons that are not merely mimic-ing existing buttons on the controller, but are completely unique.
I realised I can just do what I did before, and just have the microcontroller operate as a bluetooth keyboard like I have done before, and can add unique inputs to the controller that way.

That's a common spot for corrosion to happen on the 1708 and 1914 boards. R4 ad R7 are both 0 ohm jumpers, then C37 is 4.7nF. All of those can still be fine and the traces or a via there can have corrosion and cause issues. U4 on the other side of the board can also go screwy and cause that issue, but it looks like R4 there has probably gone open from corrosion on yours there.

Hello I have a problem, when I connect the joystick, several buttons are pressed simultaneously, I saw something suspicious in this area, can someone tell me the values or if this is where the defect comes from?

Hi there,
I've a 1708 controller whose left joystick is off horizontal center. I have replaced the horizontal axis pot, and then the entire joystick, but still cannot get the axis to center correctly. In fact, it seems to have gotten a little worse after my attempts. It seems the problem may be elsewhere on the board at this point. Is there a solution to this?
Thanks for reading!
