X-NUCLEO-53L0A1 Proximity Sensor Expansion Board Firmware Package

Introduction

This firmware package includes Component Device Drivers and the Board Support Package for STMicroelectronics' X-NUCLEO-53L0A1 Proximity sensor expansion board based on VL53L0X.

Firmware Library

Class X_NUCLEO_53L0A1 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 VL53L0X proximity sensor,
2. up to two additional VL53L0X Satellites,
3. on-board 4-digit display

It is intentionally implemented as a singleton because only one X-NUCLEO-VL53L0A1 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 X_NUCLEO_53L0A1 *board = X_NUCLEO_53L0A1::Instance(device_i2c, A2, D8, D2);

Example Applications

• Hello World 53L0
• Display 53L0A1
• Display 53L0A1 Interrupts
• Display 53L0A1 with satellites
• 53L0A1 Satellites with Interrupts
• 53L0A1_HandGestureRecognition

The library and sample application code were tested against mbed revision 143, dated 26th May 2017.
