--- Quote from: thewisteron on February 16, 2014, 09:16:49 pm ---Another question. I'm reading about the u-hid and I'm worried it can't handle 38 buttons, 4 u360s, a spinner and two light guns. I'm still not clear on all of the connections. I guess I should have figured that out before ordering :(

If only there was a FAQ entry that explained how to add up the required inputs.  :P

First up the two light guns.  Aimtraks have their own USB interface boards = not connected to UHID.

From the UHID page:

--- Quote ---Control counts which can be configured:

Total 50 connection pins.

Max 8 analog axes on 50 possible pins (Windows limitation)
Max 32 Gamepad buttons on 50 possible pins (Windows limitation)
Max 8 Quadrature mouse devices on 16 possible pins out of the 50.
Max 3 Quadrature mouse axes (X, Y and Z, Windows limitation)
Max 50 keyboard keys on 50 possible pins.
Max 16 LEDs in any combination of PC or U-HID controlled. (USB 500 mA current limitation).
Max 50 low-current output drivers.

--- End quote ---

Starting with 50 pins and subtracting as we go:

1 ground for buttons (and spinner below)
---49 pins left

38 buttons - 38 keyboard keys (or 32 gamepad buttons + 6 keyboard keys, etc.)
BTW, since you mentioned pinball flippers, there is some MAME/Pinball overlap that can free up some inputs.
---11 pins left

spinner - needs 2 data pins, 5v, and ground (piggyback on button ground to save pins)
---8 pins left

Looks like you need more inputs for the 4 u360s and 16 LED channels mentioned above.  :dunno

I'm curious why you did a u-hid? I would have done an I-pac4 myself. I don't think I would go full-RGB, either, on a 4 player just due to the sheer amount of wiring involved.

Hey, that is a handy link!

I was going to use the USB cable for all four of the U360s, so I shouldn't need pins for those.  I am also just realizing that they already include 10 pin headers for 8 additional buttons per joystick.  That is a pleasant surprise!

I went with UHid because of the LED + button combo.

I'll see if I can do what I need to do with the Uhid/U360s when they arrive this week.

thewisteron - Do you have notifications turned on so you see when you get PMs? I've been waiting to hear back from you.
