Pad help, please. PS2 DS2 "A" Series (18-pin)


#1

I’m attempting to use the SpiffyShoes solderless PCB hack but am having difficulty with this PS2 DualShock 2 “A” series board. I’ve determined the pin layout to be:

  1. L2
  2. L1
  3. Up
  4. Left
  5. Down
  6. Right
  7. Select
  8. Analog
  9. Start
  10. Ground (for 7, 8, 9)
  11. Ground (for other buttons, directions)
  12. ?
  13. Square
  14. Cross
  15. Circle
  16. Triangle
  17. R1
  18. R2

By using the #10 ground, I am able to get Select and Start to work (and presumably Analog). However, I cannot seem to get any other buttons/directions to work. I have tried using 10, 11, and 12 as a ground but can’t seem to get them to register.

I’m not even sure what 12 really is and I’m sure that’s part of my problem.

Can anybody give me a hand with this? I’ve been through the packhacking thread but didn’t see any mention to the 18-pin DS2, only the 16-pin DS that SpiffyShoes used in his article.

Thanks.

spiffyshoes is for DS1 not DS2


#3

You should probably post this in the padhacking thread.


#4

I saw that he used a DS1 but since this board is so similar (except it has two extra pins), I didn’t see why it wouldn’t work for it, too.


#5

IIRC, the analog buttons complicate things.


#6

I’ll try that. Thanks.


#7

I honestly thought I would have trouble with the Select/Start/Analog buttons (since they had their own dedicated ground) but they are the only ones that seem to work. It’s everything else that doesn’t!

The complete opposite of what I was expecting.


#8

I believe someone posted that the voltage in the pad decreases as more buttons are depressed. Maybe something related to that is causing problems?


#9

You are misinterpreting, he is not referring the the button labeled “Analog” but the fact that every button except Start/Select/Analog are themselves analog, i.e. pressure sensitive.


#10

You’re right, I was misinterpreting. Thanks for the clarification, Mayhem.


#11

this makes sense
