單片機源程序如下:

/* This example shows how to get single-shot range
measurements from the VL53L0X. The sensor can optionally be
configured with different ranging profiles, as described in
the VL53L0X API user manual, to get better performance for
a certain application. This code is based on the four
"SingleRanging" examples in the VL53L0X API.
The range readings are in units of mm. */

LiquidCrystal Library
Demonstrates the use a 16x2 LCD display. The LiquidCrystal
library works with all LCD displays that are compatible with the
Hitachi HD44780 driver. There are many of them out there, and you
can usually tell them by the 16-pin interface.
This sketch prints "Hello World!" to the LCD
and shows the time.
The circuit:
* LCD RS pin to digital pin 12
* LCD Enable pin to digital pin 11
* LCD D4 pin to digital pin 5
* LCD D5 pin to digital pin 4
* LCD D6 pin to digital pin 3
* LCD D7 pin to digital pin 2
* LCD R/W pin to ground
* LCD VSS pin to ground
* LCD VCC pin to 5V
* 10K resistor:
* ends to +5V and ground
* wiper to LCD VO pin (pin 3)
