Latest analog joystick code

[Vojtech P. <vo...@su...>]

Hi!

Just wanted to inform you that I ran an interesting test today:

First, I digged out a very old original IBM design NS558 based gameport,
and my 5 years old QuickShot QS-201 analog joystick, cleaned the
joystick thoroughly, applied some special contact cleaning and contact
care sprays to all the pots in the joystick, and silicone grease to all
bearings.

Then I used my latest analog code (with two stage noise filtration) to
read data from the joystick. And, I've got 10.5 bits of precision from
it. That's more than most digital joysticks can do ... Compared to BIOS
routine which does 5-6 bits, this is quite nice. I wonder how much
Windows drivers do get.

I was also surprised about how much difference proper care of the pots
made - before I applied the sprays and silicone, the resolution was
somewhere about 8.5 bits.
