The source code and documentation for the library Limor demonstrates can be found on GitHub. Under the hood, it’s an I2C based API which has beed abstracted into something Pythonic. The code example included in the README (reproduced below) demonstrates how easy it is to use the LIDAR sensor with CircuitPython. In only a few lines of code it outputs data which Mu can use with its built-in plotter:
import time import board import busio import adafruit_lidarlite # Create library object using our Bus I2C port i2c = busio.I2C(board.SCL, board.SDA) # Default configuration, with only i2c wires sensor = adafruit_lidarlite.LIDARLite(i2c) while True: try: # We print tuples so you can plot with Mu Plotter print((sensor.distance,)) except RuntimeError as e: # If we get a reading error, just print it and keep truckin' print(e) time.sleep(0.01) # you can remove this for ultra-fast measurements!
It’s at this point in geeky blog posts that it’s traditional to bring up sharks, lasers and Dr.Evil. Happily, I ironically understand apophasis. ;-)
