Function Documentation

◆ VL53L1X_CalibrateOffset()

int8_t VL53L1X_CalibrateOffset	(	uint16_t	dev,
		uint16_t	TargetDistInMm,
		int16_t *	offset
	)

This function performs the offset calibration.
The function returns the offset value found and programs the offset compensation into the device.

Parameters

TargetDistInMm target distance in mm, ST recommended 100 mm Target reflectance = grey17%

Returns: 0:success, !=0: failed; offset pointer contains the offset found in mm

◆ VL53L1X_CalibrateXtalk()

int8_t VL53L1X_CalibrateXtalk	(	uint16_t	dev,
		uint16_t	TargetDistInMm,
		uint16_t *	xtalk
	)

This function performs the xtalk calibration.
The function returns the xtalk value found and programs the xtalk compensation to the device.

Parameters

TargetDistInMm target distance in mm
The target distance : the distance where the sensor start to "under range"
due to the influence of the photons reflected back from the cover glass becoming strong
It's also called inflection point
Target reflectance = grey 17%

Returns: 0: success, !=0: failed; xtalk pointer contains the xtalk value found in cps (number of photons in count per second)
