Reading controller axes and mapping
Gamepad API exposes an ordered list of buttons and axes, a device identifier and mapping.
Gamepad API exposes an ordered list of buttons and axes, a device identifier and mapping. A standard mapping offers a common arrangement; an empty mapping does not establish a defect. Never assume numbered inputs have the same physical labels on every Xbox, PlayStation, Switch or generic controller. Axis pairs 0/1 and 2/3 are drawn when present. Some devices use other arrangements. Resting values, ranges and paths are reported observations, affected by drivers and calibration. The deadzone preview is an axial filter applied only to the display. The tool does not change the controller firmware or your game settings.
Measurement limits
A browser observes events exposed by your operating system. One test cannot establish whether a device is faulty. Connection, settings, focus and browser behavior can change the results.
