If you are debugging your own driver, use the structured troubleshooting workflow provided by Microsoft for I2C HID devices. Use kernel debuggers (like WinDbg) and HID-specific tools to capture traces of the communication between your driver, the HID class driver, and the device firmware. This will help you isolate whether the problem is in the initialization sequence, the HID report parsing, or the coordinate mapping logic.
Allows the device to communicate standard touch reports to Windows. kmdf hid minidriver for touch i2c device calibration best
Allow a user-mode service to write new calibration values to the registry and send a custom IOCTL to the driver. The driver should reload parameters and optionally reset the I²C device. If you are debugging your own driver, use
Implementing calibration in a KMDF HID minidriver for an I2C touch device is powerful but must be done carefully. Follow these best practices: Allows the device to communicate standard touch reports
A superior driver:
If your screen is horizontally/vertically inverted, or only touches in a corner of the screen, the calibration parameters in the .fw file do not match your display resolution.
