/* 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. */
