| Summary | Inverts the active joystick axis. |
Sometimes it is desirable to invert one or more axes to create a more intuitive user interface. The Set Axis Inversion (#27) command allows the user to set the invert status of the active axis. Use Invert Status = 1 to set the current axis to non-inverted, use Invert Status = -1 to set the current axis to inverted. Use Invert Status = 0 to toggle between invert and non-invert (the Invert Status of the reply will still be either 1 or -1).
See the Set Active Axis (#25) instruction for information on how to select an axis. Each axis can be inverted independently of the other two axis. See command #26 for an example of how to invert a particular axis.
Here are the default directions for each axis (not inverted):
- On axis 1, left is negative and right is positive.
- On axis 2, down is negative and up is positive.
- On axis 3, counter-clockwise is negative and clockwise is positive.
What constitutes positive or negative motion depends on the device; see the user’s manual for the device in question. The default axis inversion setting for all joystick axes is non-inverted.
