X-NUCLEO-53L1A1 Proximity Sensor Expansion Board Firmware Package

Introduction

This firmware package includes Component Device Drivers and the Board Support Package for STMicroelectronics' X-NUCLEO-53L1A1 Proximity sensor expansion board based on VL53L1X.

Firmware Library

Class XNucleo53L1A1 is intended to represent the Proximity sensor expansion board with the same name.

The expansion board provides support for the following components:

  1. on-board VL53L1X proximity sensor,
  2. up to two additional VL53L1X Satellites.

It is intentionally implemented as a singleton because only one X-NUCLEO-VL53L1A1 may be deployed at a time in a HW component stack. In order to get the singleton instance you have to call class method `Instance()`, e.g.:

// Sensors expansion board singleton instance
static XNucleo53L1A1 *board = XNucleo53L1A1::instance(device_i2c, A2, D9, D2);

Example Applications
