Kmdf Hid Minidriver For Touch I2c Device Calibration
These offsets should ideally be stored in the Registry or an ACPI _DSD (Device Specific Data) method so the driver can load them at boot without hardcoding values. Axis Inversion and Swapping
Some devices require writing to registers to activate calibration mode. kmdf hid minidriver for touch i2c device calibration
This write‑up focuses on implementation for maximum calibration control. These offsets should ideally be stored in the
