KMDF HID Minidriver for Touch I2C Device (often associated with
// Process calibration data sensitivity = ProcessSensitivity(sensitivity); offset = ProcessOffset(offset); gain = ProcessGain(gain); kmdf hid minidriver for touch i2c device calibration best
The following example code illustrates a basic calibration implementation in a KMDF HID minidriver: KMDF HID Minidriver for Touch I2C Device (often
- Gain and offset values for X and Y coordinates
- Touch pressure sensitivity
- Gesture recognition
- Use
WPPtraces to log raw and calibrated coordinates. - Enable HID debugging (
!hidpdpin WinDbg) to see final touches entering the input stack.
// Get calibration data from device ULONG sensitivity, offset, gain; GetCalibrationData(device, &sensitivity, &offset, &gain); Gain and offset values for X and Y
