Linux Hardware Device Management

Given knowledge of the I2C and Onewire hardware protocols, learn how to treat such devices from userspace on Linux.

There are different aspects to device management, at least regarding I2C, Onewire, and the semantic aspect of being a sensor device

• I2C communication from userspace: using the I2C bus devices

• Onewire communication from userspace: the Onewire filesystem

• hwmon, covering sensor devices in a generalized way (here)
