Joystick Calibration and Testing

Microsoft Windows® 95 provides a joystick application in the Control Panel to calibrate and test joysticks, including range of motion and buttons. This application lets the user choose from a list of joysticks, including the following:

·Generic joystick configurations

·OEM joysticks

·Custom joysticks

The application allows the calibration of up to six axes of motion, 32 buttons, and a point-of-view hat for each joystick. Calibration information is stored in the registry, so the user can switch from one joystick to another without recalibrating each one every time it is used. Once the user has calibrated or selected a new joystick, the calibration application updates the registry with the selected joystick and calibration information, and notifies the joystick driver accordingly.

Additionally, this application can notify a particular joystick of changes to the registry that affect the joystick, by using the joyConfigChanged function.
