Once the minidriver is deployed, use these tools to verify calibration: kmdf hid minidriver for touch i2c device calibration

You will implement a helper function to extract this blob. Store the calibration data in your device context

The KMDF (Kernel-Mode Driver Framework) HID minidriver serves as the critical communication bridge between a Touch I2C controller and the Windows Input Stack. When dealing with touch hardware, raw electrical signals must be translated into precise screen coordinates. Without proper calibration, a user’s tap may register inches away from the actual contact point. kmdf hid minidriver for touch i2c device calibration
