i2c DS2482-100

Notes: The DS2482-100 is an i²c slave and 1-wire bus master.

i²c is a chip-to-chip protocol developed by Phillips
- A subset of the protocol, SMBUS is used extensively in modern PCs, for configuration of memory, audio, sensors, etc... See lm-sensors.
- The Linux kernel has drivers for many i2c masters
- The i²c master can be opened as a device: /dev/i2c-n where n in an integer.
- More sophisticated address control can be specified.
- Extensive information is available.
A list of available i²c masters can be seen in /sys/class/i2c-adapter
- /dev/i2c-0 should be used on the command line (analogous to /dev/ttyS0 for serial)
- The address of the DS2482 on that i²c bus will be auto-probed. This might cause problems with other i²c slaves on that bus.

See also the DS2482-800 -- an 8 channel version of this chip.

Note: Much of the motivation and testing of the DS2482 support are due to Jan Kandziora and Daniel Höper.
