Direttamente da /usr/src/linux/Documentation/i2c/summary si legge:
| Code: |
I2C and SMBus
=============
I2C (pronounce: I squared C) is a protocol developed by Philips. It is a
slow two-wire protocol (10-400 kHz), but it suffices for many types of
devices.
SMBus (System Management Bus) is a subset of the I2C protocol. Many
modern mainboards have a System Management Bus. There are a lot of
devices which can be connected to a SMBus; the most notable are modern
memory chips with EEPROM memories and chips for hardware monitoring.
Because the SMBus is just a special case of the generalized I2C bus, we
can simulate the SMBus protocol on plain I2C busses. The reverse is
regretfully impossible.

"Questo dispositivo lo supporta???" |
per esempio, la misura della velocita' delle ventole (e il controllo della velocita') funziona su SMBus |
