ST VL53L4CX - Bare Driver Basic Functions Description; Bare Driver

3 Bare driver basic functions description
This section describes the driver function calls flow that should be followed to perform a ranging measurement
using the VL53L4CX.
The VL53L4CX driver is used in two classes of applications:
• Factory applications used for device calibration, typically at the end of product manufacturing test (factory
flow)
• Field applications, which include all end-user applications using the VL53L4CX device (ranging flow)

GetCalibrationData()
Save part calibration data
Note: The calibration flow changes the distance mode. It is mandatory to call the SetDistanceMode() function if you
want to use the sensor just after a calibration.
Bare driver ranging flow is illustrated in the following figure.
