Introduction¶

CircuitPython driver for the DS2413 one wire 2 channel GPIO breakout.

Dependencies¶

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.

Usage Example¶

import time
import board
from adafruit_onewire.bus import OneWireBus
import adafruit_ds2413

ow_bus = OneWireBus(board.D2)
ds = adafruit_ds2413.DS2413(ow_bus, ow_bus.scan()[0])

led = ds.IOA
button = ds.IOB
button.direction = adafruit_ds2413.INPUT

while not button.value:
    led.value = True
    time.sleep(0.5)
    led.value = False
    time.sleep(0.5)
