Summary
In this chapter, we discovered the 1-Wire bus and how it can be used in order to get data from a simple temperature sensor device. We used a 1-Wire controller emulated by the GPIO interface and a more complex I2C device, which implements a complete 1-Wire controller. In both cases, we discovered that device management is almost the same and it's very simple.
In the next chapter, we're going to see another kind of bus that allows us to exchange data with several remote computers and that is at the base of almost every local computer network: Ethernet devices.
