Kmdf Hid Minidriver For Touch I2c Device Calibration Best _best_

| Pitfall | Consequence | Solution | |---------|-------------|----------| | Blocking I2C reads in ISR | High DPC latency | Use WdfRequestSend with no-wait flag | | Incorrect HID descriptor | Touch not recognized | Validate with USB.org HID Descriptor Tool | | Missing synchronization | Corrupt calibration | Guard with WdfSpinLock | | Kernel stack overflow | BSOD | Limit recursion; use WDF_NO_OBJECT_ATTRIBUTES |

Perform minimal calibration in the KMDF minidriver. Move complex, non-time-critical calibration to a user-mode service. The kernel driver should only apply final scaling and clipping. kmdf hid minidriver for touch i2c device calibration best
