[avr-gcc-list] Gamepad


HISorry for putting this mail here, but I thought since this mailing list
deals with avr u people will be electronics hobbist and may help me.I am designing a robot for a competition. It is manual and needs a
controller, for which I figured to use a gamepad, sony/dreamcast, but
thhe problem is interfacing it with atmega16. Can someone tell where to
find datasheets foe these/ what are the pins supposed to be connected
to.The dreamcast remote has a rotating control for speed, how does that thing work and how do i read it.ThanksspsIITK_______________________________________________

I'd imagine you'd be hard pressed to find a datasheet for a game console
controller.. About the best you could hope for is that someone has reverse
engineered it. Even then it's likely they won't publish the details.

I would suggest that you get an *old* PC joystick (ie one with a D15 connector
that plugs into a game port) and use that. They have simple close contact
switches and pots you can read with an ADC.

There is an interested (but gross :) analog stick.. an old MS sidewinder - it
has pseudo analog mode, but if you read from it in the right sequence it goes
into digital mode where it sends data out via the joystick button lines..
Gross, but pretty neat all the same :) There is some Linux code which groks
this beast..http://glide.stanford.edu/lxr/source/drivers/input/joystick/sidewinder.c?v=linux-2.6.10MS even have a patent on it..

Please use avr-chat then. That's exactly what it has been established
for: to get in contact with about the same community as avr-gcc-list
(minus those who really aren't interested), yet discuss things that
are not related to avr-gcc but are ``related'' somehow.

Never trust an operating system you don't have sources for. ;-)
