Define a custom IOCTL in your header:

Standard Windows calibration tools often fail to fix these issues because they are typically caused by a mismatch between the driver version and the specific touch panel firmware (e.g., Silead or MSSL1680). Power Management Bugs:

Your KMDF driver alone cannot perform calibration; it only applies it. A user-mode application must guide the user, collect points, compute coefficients, and call DeviceIoControl .

To support calibration changes at runtime (e.g., from a user-mode calibration app), you implement a custom IOCTL handler:
