The following example code illustrates a basic calibration implementation in a KMDF HID minidriver:
// Process calibration data sensitivity = ProcessSensitivity(sensitivity); offset = ProcessOffset(offset); gain = ProcessGain(gain); kmdf hid minidriver for touch i2c device calibration best
In this article, we discussed the best practices for calibrating a touch I2C device using a KMDF HID minidriver. By following these best practices, developers can ensure accurate and reliable touch input for their touch I2C devices. The example code provided illustrates a basic calibration implementation in a KMDF HID minidriver. The following example code illustrates a basic calibration
// Calibration commands #define CALIBRATION_CMD_GET_SENSITIVITY 0x01 #define CALIBRATION_CMD_SET_OFFSET 0x02 // ... offset = ProcessOffset(offset)
// Store calibration settings StoreCalibrationSettings(device, sensitivity, offset, gain); }
