I use pypi installed adafruit_onewire, and adafruit_ds18x20,but when I run :

import board
from adafruit_onewire.bus import OneWireBus
ow_bus = OneWireBus(board.SCLK_1)
devices = ow_bus.scan()
for d in devices:
print(“ROM={}\tFamily=0x{:02x}”.format(d.rom, d.family_code))

the result is:Traceback (most recent call last):
File “/home/a/UnderwaterAI/18b20.py”, line 3, in
ow_bus = OneWireBus(board.SCLK_1)
File “/home/a/.local/lib/python3.6/site-packages/adafruit_onewire/bus.py”, line 62, in init
self._ow = busio.OneWire(pin)
File “/home/a/.local/lib/python3.6/site-packages/busio.py”, line 481, in init
raise NotImplementedError(“OneWire has not been implemented”)
