3.5 Temperature update
Ambient temperature has an effect on ranging accuracy. In order to ensure the best performances, a temperature
update needs to be applied to the sensor. This update needs to be performed when the temperature might have
changed by more than 8 degrees Celsius.
A dedicated function named ‘VL53L4CD_Start_Temperature_Update()’ has to be used. The function can
only be used if the sensor is not ranging. Otherwise, the ranging needs to be stopped using function
'VL53L4CD_StopRanging()'. After calling this function, the ranging can restart normally.
