Introduction

This document describes how to get started with the X-CUBE-53L1A2 software expansion for STM32Cube.

The VL53L1 is a state of the art Time-of-Flight (ToF) laser-ranging miniature sensor, enhancing the ST Flight Sense product

family. Housed in a miniature and reflowable package, it integrates a single photon avalanche diode (SPAD) array, physical

infrared filters and optics to achieve the best ranging performance in various ambient lighting conditions, with range of cover

glass options.

Unlike conventional IR sensors, VL53L1 uses ST’s latest generation direct ToF technology which allows absolute distance

measurement whatever the target color and reflectance. It provides accurate ranging up to 8 m and can work at fast speed (60

Hz), which makes it the fastest miniature ToF sensor on the market.

With patented algorithms and ingenious module construction, VL53L1 is also able to detect different objects within the field of

view (FoV) with depth information (histogram) at 60 Hz.

X-CUBE-53L1A2 provides a complete software for STM32 to build applications using the VL53L1 ToF sensor.

It is easily portable across different MCU families thanks to STM32Cube. This package contains a sample application to transmit

the ranging data to a PC.

The software provides an implementation example for STM32 Nucleo platforms equipped with the X-NUCLEO-53L1A2

expansion board, featuring the distance ranging sensor.

The software is based on STM32Cube technology and expands STM32Cube based packages.
