range of joystick input?

isaacdl · #1 13-06-2010, 21:16

I'm setting up a throttle control for our bot, using the Z axis (throttle control). The code I'm using to get the value of the Z axis is:

Code:

throttleSpeed = rightStick.getZ() ;

(throttleSpeed is type double.) I need to know what range the value of throttleSpeed could be. Is it -1 to 1, or 0 to 1, or 1 - 255, or something completely different?

-1 to 1, where -1 is flat, 0 is half way up, 1 is completely up. We've used throttle control the past two years where

Code:

throttleSpeed = (rightStick.getZ()+1)/2 ;

Perfect, thank you.
