9 1-Wire is a low speed half-duplex serial bus using only a single wire plus
11 Similarly to I2C, 1-Wire uses a bidirectional open-collector data line,
14 The 1-Wire bus supports longer bus lines than I2C, while it reaches speeds of up
17 over a bus length of 100 meters. Using overdrive speed, 3 nodes on a bus of
19 fewer nodes on the bus may allow to reach larger bus extents.
