VL53L1X

From the datasheet: "The VL53L1X is a state-of-the-art, Time-of-Flight (ToF), laser-ranging sensor, enhancing the ST FlightSenseā„¢ product family. It is the fastest miniature ToF sensor on the market with accurate ranging up to 4 m and fast ranging frequency up to 50 Hz."

Wiring

The wiring is the same than any other I2C module. Most of the already available modules also have pins for shutdown (SHUT) and an interrupt (GPIO1).

You need to wire up as follows:

Pin Name Espruino
1 GPIO1 N/C
2 SCL I2C SCL (B6)
3 XSHUT 3.3v
4 SDA I2C SDA (B7)
5 VDD 3.3v
6 GND GND

Software

You can use the VL53L1X (About Modules) module with the VL53L1X as follows:

I2C2.setup({sda:B3,scl:B10});
digitalWrite(B4,1); // set XSDN -> turn the sensor on
var laser;
setTimeout(function() {
  laser = require("VL53L1X").connect(I2C2);
  // make one reading
  console.log(laser.performSingleMeasurement().distance+" mm");
  // or repeatedly measure
  setInterval(function() {
    // sets LED brightness depending on distance
    var dist = laser.performSingleMeasurement().distance;
    analogWrite(LED1, (300-dist)/300, { soft:true, freq:200 });
  }, 50);
});

XSHUT isn't needed and can be connected to 3.3v. It is used for powering the device on and off (and you must leave a 2ms delay between powering the VL53L1X on and using it).

VL53L0X Compatibility

The API of the module is partially compatible with the VL53L0X module. Just replace require("VL53L0X") by require("VL53L1X") in your code and it should work. The function performSingleMeasurement is provided as an alias of readMeasurement in order to keep the backward compatibility.
