Semiconductor Corp. that provides low-speed data, signaling, and power over a
single conductor. It is typically used to communicate with small inexpensive
devices such as digital thermometers and iButton devices. iButton®
devices are small, durably packaged modules with globally unique digital
addresses.
With its integrated 1-Wire interface, VG710 acts as bus master could
communicate with iButton device or 1-Wire thermometer.
Users should first correctly install their 1-Wire device, and then they can check
