ST VL53L8CX - Functional Description of VL53 L8 CX; System Overview; Effective Orientation

2 Functional description
2.1 System overview
The VL53L8CX system is composed of a hardware module and the ultra lite driver software (VL53L8CX ULD)
running on a host (see figure below). The hardware module contains the ToF sensor. STMicroelectronics delivers
the software driver, which is referred to in this document as "the driver". This document describes the functions of
the driver, which are accessible to the host. These functions control the sensor and get the ranging data.

2.2 Effective orientation
The module includes a lens over the RX aperture, which flips (horizontally and vertically) the captured image of
the target. Consequently, the zone identified as zone 0, in the bottom left of the SPAD array, is illuminated by a
target located at the top right-hand side of the scene.
