Kmdf Hid Minidriver For Touch I2c Device Calibration Best ^hot^

For touch device calibration, accuracy depends on how the driver handles coordinate mapping and data persistence. Calibration Persistence : Store calibration data (matrices or offsets) in the device's hardware registry key or the driver's Parameters\Wdf

Implementing a KMDF HID Minidriver for I2C touch devices requires navigating a unique "driver pair" architecture. Because the HID class driver ( hidclass.sys
