    • Edge distortion (common in projected capacitive touch) may require a second-order polynomial or a lookup table. Implement this in the minidriver only if the controller’s firmware lacks native correction.

    Implement I2CReadRegister() and I2CWriteRegister() using WdfIoTargetSendI2cWriteRead. kmdf hid minidriver for touch i2c device calibration best

    Windows touch devices (I2C HID digitizers) often require calibration to map raw sensor coordinates to screen coordinates. While user-mode calibration via TouchCalibration (tabcal) exists, kernel-mode calibration inside a KMDF HID minidriver is necessary when: Provide vendor utility:

    This document outlines best practices for implementing calibration in a KMDF HID minidriver for an I2C touch device. Logging:
