I²C, SMBus and hardware monitoring references

This document contains all kinds of useful references to I²C and SMBus documents and implementations, and to hardware sensors documentation and implementations. Please report any other references you have found!

I²C
- General overview
- I²C FAQ
- Philips, the I²C developers
  This site contains many example programs
- Simon Vogl's I²C Linux kernel module
SMBus
- SMBus specification documents
I²C and SMBus implementations
- Intel PIIX4 (82371AB)
  Intel SMBus adapter, integrated with many other functions. There are datasheet for most chipsets.
- VIA South Bridge (VT85C586B)
  VIA I²C adapter, integrated with many other functions. There is a separate section with datasheets.
