Joystick-Servo control

[Lumit]

So we want to have the servos on the camera mount controlled by a joystick.
our camera mount: http://andymark.biz/am-0568.html

I have a feeling the issue is our number range conversion.

As I understand it, the joystick axes output a value of -127 to 127.
And the servos can use 0 to 1 (with set position) or 0 to 180 (with set angle).

So I added 127 to the joystick input, then divided it by 255, then fed that value into the set position VI. When powered up, it locks itself facing straight upwards, and wont respond to the joystick.

Am I missing something? It feels mathematically solid yet it isn't working! :P

thanks

If you use Joystick Get, the joystick value is -1 to 1.
Use that with Servo Set Position.
Just feed it directly for your first test without any mathematical manipulation.
