*USB* to analog joystick.

PCMCIA cards are used for all sorts of things. I want to replace a key or two on a keyboard on a laptop (or a free space on the case) with a PSP Joystick. Since there is a roundabout way to do this (Joystick to USB to PCMCIA), I was hoping there could be a more direct route to accomplishing such a task.

Has it been done before? (Analog input of PCMCIA in general)

How would I learn enough to accomplish this?

Would I have to build my own drivers?

I know old PCMCIA sound cards sometimes had an analog joystick port, usually on a breakout of some sort.

To make you're own, you'd need an ADC, then glue logic to bind it to the signals of PCMCIA (a varient of ISA, or PCI is it's Cardbus).

How old is this laptop? If doesn't have 32-bit Cardbus slots (same size, and backward compatible with PCMCIA, and for bonus points often called PCMCIA) the USB 2.0 cards won't work with it.

The said laptop is not in my possession yet, but I think it's fairly new. Not more than 3 years for sure. It might even be a Core Duo (although I doubt it).

Mind speaking in English? You're on to something, but I didn't understand a lick of it.

ADC == analog to digital converter. Makes the joystick's analog signal readable by the digital computer.

Erm...I think I'll take an easier route. A USB hub shoved inside the computer, with a USB Gamepad's guts (just the part for the analog) attached to one of the ports.

Does anyone know the USB gamepad with the smallest guts?

*Bump*

Could someone take pictures of various USB gamepads for me? I'm sure several of you have some. Looking inside an Xbox controller, there seems to be much work to do as far as tracing and removing unnecessary circuits goes.

Even pictures of the inside of a hipgear/intec controller would be fine, as I do believe there are USB models of the dualshock.

Well, I am new to the forums, but I do have some experience with this sort of thing.

Have you considered using a pulse wave via a PIC? It would require programming the PIC to identify the the resistive value, then convert it to a digital pulse wave.

Over at http://www.acidmods.com we are using pulse waves in order to make rapid fire in the 360 SpitFire modded controller:

Something like that would be perfect for what you are trying to do.
