// Process calibration data sensitivity = ProcessSensitivity(sensitivity); offset = ProcessOffset(offset); gain = ProcessGain(gain);
The following example code illustrates a basic calibration implementation in a KMDF HID minidriver: kmdf hid minidriver for touch i2c device calibration best
// Calibration commands #define CALIBRATION_CMD_GET_SENSITIVITY 0x01 #define CALIBRATION_CMD_SET_OFFSET 0x02 // ... offset = ProcessOffset(offset)
// Calibration interface #define IOCTL_CALIBRATION_SET_SENSITIVITY CTL_CODE(FILE_DEVICE_UNKNOWN, 0x800, METHOD_BUFFERED, FILE_ANY_ACCESS) // ... gain = ProcessGain(gain)
