For engineers developing touch solutions over the I2C (Inter-Integrated Circuit) bus, the challenge is twofold. First, the device must conform to Windows' HID (Human Interface Device) standards. Second, it must account for physical variances in the touch sensor, display lamination, and environmental drift. The most robust solution to these challenges is a specifically architected for I2C touch device calibration. NTSTATUS ApplyCalibrationToHardware(WDFIOTARGET I2CTarget
