Project description


Documentation Status Discord Build Status Code Style: Black

Classes for use in communicating with devices on a 1-Wire bus.


This driver depends on:

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

Note: This library does not work on the Raspberry Pi as there is no kernel interface for it

Usage Example

import board
from adafruit_onewire.bus import OneWireBus
ow_bus = OneWireBus(board.D2)
devices = ow_bus.scan()
for d in devices:
    print("ROM={}\tFamily=0x{:02x}".format(d.rom, d.family_code))


API documentation for this library can be found on Read the Docs.
