Subject: analog joystick (allegro)
Precedence: bulk


Anyone having experience with analog joysticks? I bought a 
Logitech Wingman Extreme and when using the allegro
poll_joystick() function - I think it's a general problem with 
the analog port (a/d) - I find that it is extremely noisy.

Coordinates jump randomly in a +20/-20 units range of the
total +255 - 256 full scale range.

Can one do anything about it in hardware? Like shielding ?
I might filter this out by masking off the four least significant
bits of the coordinate values but I'd hate to do this.
