-Controlling 1-wire devices
-==========================
-
-The 1-wire bus is a serial bus that uses just a single wire for communication
-(in addition to wires for ground and power).  The DS18B20 temperature sensor
-is a very popular 1-wire device, and here we show how to use the onewire module
-to read from such a device.
-
-For the following code to work you need to have at least one DS18S20 or DS18B20 temperature
-sensor with its data line connected to GPIO12.  You must also power the sensors
-and connect a 4.7k Ohm resistor between the data pin and the power pin.  ::
-
-    import time
-    import machine
-    import onewire, ds18x20
-
-    # the device is on GPIO12
-    dat = machine.Pin(12)
-
-    # create the onewire object
-    ds = ds18x20.DS18X20(onewire.OneWire(dat))
-
-    # scan for devices on the bus
-    roms = ds.scan()
-    print('found devices:', roms)
-
-    # loop 10 times and print all temperatures
-    for i in range(10):
-        print('temperatures:', end=' ')
-        ds.convert_temp()
-        time.sleep_ms(750)
-        for rom in roms:
-            print(ds.read_temp(rom), end=' ')
-        print()
-
-Note that you must execute the ``convert_temp()`` function to initiate a
-temperature reading, then wait at least 750ms before reading the value.
