No 1-Wire controller - a GPIO is used instead

1-Wire is a registered trademark of Dallas Semiconductor for a device communications bus systems designed by Dallas Semiconductor that provides low-speed data, signalling and power over a single signal, albeit using two wires, one for ground, one for power and data. 1-Wire is similar in concept to I2C, but with lower data rates and longer range. It is typically used to communicate with small inexpensive devices.
