6 I2C (pronounce: I squared C) is a protocol developed by Philips. It is a

15 Because the SMBus is just a special case of the generalized I2C bus, we
16 can simulate the SMBus protocol on plain I2C busses. The reverse is
23 When we talk about I2C, we use the following terms:
30 of I2C adapters. Each specific adapter driver depends on one algorithm
37 For a given configuration, you will need a driver for your I2C bus (usually
38 a separate Adapter and Algorithm driver), and drivers for your I2C devices
