PSP/Dualshock Control Pinouts and Info

[Blazinkaos]

I get really close to getting this done but i need something to connect the PS2 controller to PSP and i dont want to use those small usb.

[FaT3oYCG]

if you go to sparkfun and get an ipod connector it works great, i already had some to do this mod and didnt end up using these images as i had a sony schp 110 controller so i had to use my multimeter to try it out myself but i think i made the cable too small :P.

ill get some more kynar wire and another connector so i can re do it .

EDIT:
got the wire i just need the connector from sparkfun now :P.

Oh yea blizzrad showed me that now i remember now getting money the side for is another -_-.

[Blizzrad]

Ok, I think I finally have everything properly sorted out with this thread. The images and text are back together once again in the original post, and all is well in the magical kingdom.

   i want to determine which one is up down left and right to encircled part of the psp 1000 main board... i am going to directly contact my joystick and replace my original psp joystick to K800i joystick... pls help thak you...

Read this vhin its all explained here in the first post of blizzrad.

Analog Stick Contacts

The joystick contacts on the motherboard can be wired to external potentiometers to provide analog input. If you aren't familiar with how this type of potentiometer based joystick works, here is a basic summary.

Potentiometers are variable resistors, inside them is a resistive material with three pins connected to it. On either end of the resistive material are the power and ground pins, these typically remain at a constant voltage. The third pin is called the wiper, this is just a piece of metal that can move along the resistive material (in this case the wiper is attached to the arm of the joystick). As the wiper moves closer to ground the voltage read from this pin approaches 0, as it moves closer to the power input the wiper voltage approaches whatever the supply voltage is. When the wiper is directly in the middle, its voltage will be half of the input voltage (in accordance with Ohm's law). By reading the voltage on the wiper pin, the psp is able to determine the position of the joystick at any time.

Two different examples for providing analog input are shown in this post, one using an MCP4251 digital potentiometer, and another using hardwired Ps1 controller joysticks. When looking at your PSP motherboard in the way it would normally be oriented while using the PSP, the analog connections are as follows:

  [[ ]  ]  =GND
[  [ ]]    =X-Axis
  [[ ]]    =+2.5v
[  [ ]]    =Y-Axis

The 2.5v supply to the joystick is not constant, but pulsed for approximately 200µs at 130Hz, this can be seen in the oscilloscope view below. These 2.5v pulses are only present when the running application requires input from the joystick, otherwise the joystick supply will be at a constant 0v.

Hope this helps.

here the photo on the first page is removed, the photo there about how to connect analog

[Blazinkaos]

Going to have to get with blizzrad to fix those.

[danger007]

And why in the joystick had to hold the contact analog and GND to the PSP? If you want something where they were soldered

[Blazinkaos]

What exactly you trying to say you lost me.

[danger007]

I mean, why do we need contacts and Analog GND. In the photo I saw something that made ​​contact wire, so it means they need to connect to psp.Ya here want to know where to contact and analog GND with a joystick to be connected to the motherboard on the psp

This might be dumb to ask, and probably to late to ask as well, but can this mod work on a PSP 2000 Sysytem?

[Blazinkaos]

Man this is old and Yes it can be done just more difficult to compact the wires.

[The_Art_Of_Deth]

Awesome! Now all I need to do is find a Modder for Hire who can do this mod on my PSP at a Fair price, as I don't have the technical know-how or supplies to do this mod myself... Any chance you know of anyone who can? I looked all over the "Modder's For Hire" page here on Acidmods.com and no one replied to the emails I sent. I guess everyone just stopped doing mods as a paying job. I Appreciate the Info and Thanks in Advance!

Yea thats all you bro i dont know anyone off hand that does that anymore its been long time since i done it. Im also much older and have more responsibilities or else i would say yes. Good luck.

[The_Art_Of_Deth]

I see... Is there any possibility at all that, whenever you have the time, you can accept the job? Now I don't wanna come off as rude or offensive, disrespectful or demanding in anyway, I'm just really at witts end. I looked everywhere for people who can do this Mod with absolutely no luck at all. Like I said, is there any chance at all you can accept this Mod as a service request? I understand you have responsibilities and more important things to do in real life... but please, on the very small tiny bit of hope I got left in me, can you consider doing me this Mod please?    Whenever you can spare your time, wether its in 6 months from now, 3 years from now or even 1 decade from now, I'll wait as long as it takes... What do you say?

Thanks again for your time and replies! Have a Good One!

PS: never hurts to ask.   

[Blazinkaos]

I would have to get back to you on that. For I have not modded a PSP in so long and i mean years. So I would have to relocate all my equipment i use to use so forth and supplies.

[The_Art_Of_Deth]

I completely understand and Thank You for your Cooperation! I Look forward to your reply very soon. Thanks again for the info and consideration. I appreciate it, Have a good one!
