WebHID Firmware-Level PlayStation Controller Calibration
Traditional deadzone adjustments only mask stick drift in software. WebHID zero-point sampling reads raw 16-bit analog stick values directly from the DualSense hardware microcontroller.

How do I calibrate stick zero-point offsets on PS5 DualSense or PS4 controllers?
Connect your PlayStation controller to your computer via USB cable, click "Connect DualSense via WebHID", rest the sticks in center position, and click "Sample Center Offset".
What is WebHID hardware controller calibration?
WebHID is a modern browser API that communicates directly with Human Interface Devices (HID). It enables low-level memory sampling for DualSense and DualShock controllers without installing third-party software.
Does WebHID calibration fix PS5 stick drift permanently?
Yes! Re-centering software zero-point offsets recalibrates resting center values, resolving minor stick drift caused by spring wear without requiring soldering.
