Arduino library to support the VL53L3CX Time-of-Flight ranging sensor with multi target detection

VL53L3CX

Arduino library to support the VL53L3CX Time-of-Flight ranging sensor with advanced multi-object detection.

API

This sensor uses I2C to communicate. And I2C instance is required to access to the sensor. The APIs provide simple distance measure and multi-object detection in both polling and interrupt modes.

Examples

There are 2 examples with the VL53L3CX library.

In order to use these examples you need to connect the VL53L3CX satellite sensor directly to the Nucleo board with wires as explained below:

• pin 1 (Interrupt) of the VL53L3CX satellite connected to pin A2 of the Nucleo board
• pin 2 (SCL_I) of the VL53L3CX satellite connected to pin D15 (SCL) of the Nucleo board with a Pull-Up resistor of 4.7 KOhm
• pin 3 (XSDN_I) of the VL53L3CX satellite connected to pin A1 of the Nucleo board
• pin 4 (SDA_I) of the VL53L3CX satellite connected to pin D14 (SDA) of the Nucleo board with a Pull-Up resistor of 4.7 KOhm
• pin 5 (VDD) of the VL53L3CX satellite connected to 3V3 pin of the Nucleo board
• pin 6 (GND) of the VL53L3CX satellite connected to GND of the Nucleo board
• pins 7, 8, 9 and 10 are not connected.

• VL53L3CX_Sat_HelloWorld: This example code is to show how to get multi-object detection and proximity values of the VL53L3CX satellite sensor in polling mode.

• VL53L3CX_Sat_HelloWorld_Interrupt: This example code is to show how to get multi-object detection and proximity values of the VL53L3CX satellite sensor in interrupt mode.

Note

The VL53L3CX is a fully integrated miniature module with a low power microcontroller with advanced digital firmware. Detection with full field of view (FoV) is up to 300 cm +. It works with many types of glass roofing materials. Xshutdown (reset) and stop GPIO are integrated to optimize remote operation.
