The product documentation for the 2-Axis Joystick (http://www.parallax.com/StoreSearchResults/tabid/768/txtSearch/joystick/List/0/SortField/4/ProductID/581/Default.aspx) does not mention anything about a trim for centering the joysticks, and the feature is not present on any of the several different mini joysticks that I have.

This (https://sites.google.com/site/parallaxinretailstores/home/2-axis-joystick) page clearly shows such a feature to exist. Is it really true?


A trimmer control is provided for each axis to adjust the centering value provided by the joystick. These controls are located on the sides of the joystick, under the control knob. Use a small flat-bladed screwdriver to make any needed adjustments.

No, don't think so. The mention of the trimmer has since been removed.

It still doesn't allow the joystick to return to a center value. In both or all directions.

Center trimming is generally done in software these days to keep cost and complexity down.
