: How do you create the dead zone? We are a rookie team, and need all the programming help we can get.

There are many different ways to program a dead zone. The simplest (but not always the best) is to use an if statement.

in pseudo-code:

if joystick is greater than 117 AND joystick is less than 137 then joystick = 127

127 is the neutral position, so if the joystick value is ever +/- 10 from the neutral position, then the robot won't move. out team has found that a value of +/- between 5 and 10 works the best.

There are a few problems with this method. If you can find them, then you probably don't need help developing a dead stick routine ;-)

You should also read the whitepaper on filtering the joysticks availible from innovationfirst.com. It contains a "dead stick" routine among other things
