## W1 Device Driver

The W1 kernel device driver allows you to control 1 Wire devices connected to GPIO 4.

The drivers are not loaded by default. See Loading Device Drivers.

The drivers can be loaded dynamically with:

    modprobe wire
    modprobe w1_gpio
    modprobe w1_therm

The module HiPi::Device::OneWire gives simple read only access to the device driver functions.

It is implemented primarily to support the HiPi::Interface::DS18X20 module that allows reading of the popular 18S20 and 18B20 temperature sensors.
