Figure 4. Cross-talk calibration valid distances
2.6.3 Cross-talk calibration procedure
The following procedure has to be performed:
• Perform Offset calibration, refer to Section 2.5: Offset calibration
• Choose the calibration distance, based on a ranging with cover window to be used, as
described in Section 2.6.2: Cross-talk calibration distance.
• Use a grey 17% reflectance target.
• Call the API calibration function: VL53L0X_PerformXTalkCalibration().
• The input of this function is the calibration distance in millimeters.
• The output is the cross-talk factor. This has to be stored on Host memory.
• The function applies and enables the cross-talk correction.
• Store the cross-talk factor on the Host memory. See Section 4.3.4 for loading
calibration data from Host.
Note: The API function VL53L0X_PerformXTalkCalibration() performs several
measurements, means and computation. Nothing has to be done on the Host side, except
calling this function, all is performed by the API.
